Safe Exam Browser – SEB for macOS opens a web browser window without navigation elements and locks the computer into a kiosk mode, which prevents from switching to other applications or quitting SEB untimely.SEB enables secure exams on unmanaged computers like students' own laptops as well as in managed environments. Currently SEB integrates with the wide spread learning management systems (LMS) Moodle, ILIAS and OpenOLAT and several non-commercial and commercial exam systems, as for example Inspera Assessment. Generally it can easily be used with most web-based online quiz and e-assessment systems.

To prevent switching to other applications or interrupting an exam, SEB disables the macOS Dock, the process switcher (cmd-tab/cmd-shift-tab), the Apple Menu and various other items in the menu bar, the Force Quit window (cmd-opt-esc), normal reboot (ctrl-cmd-eject), normal shutdown (ctrl-opt-cmd-eject), hiding the application, printing, Exposé, screenshots and the Notification Center.

Display and system idle sleep is also prevented while SEB is running. It can also be set whether users can quit SEB and if it is required to enter a quit password to do so.

Its possible to configure SEB to quit after the exam is submitted without having to enter a quit password by specifying a quit link and placing this on the summary page displayed by the LMS after submitting the exam.

In the browser window there is no right mouse (or ctrl-) click popup window available, links requesting to be opened in a separate window can be set to be blocked generally, to open in the same browser window or in a new SEB window. Besides that, the browser is supporting Java, Quicktime and Flash content (as long as the required plugins are installed on the system). SEB can also be configured to always use the more secure internal PDF viewer instead of the Acrobat Reader plug-in.

SEB features an optional dock/task bar displaying an icon for the SEB browser with controls for its open browser windows and widgets. Buttons in the dock for quitting SEB, restarting exam, reloading page and a display for the current time improve usability in exams. Clicking the SEB icon in the dock and holding the left mouse button down or a secondary (right mouse button) click displays a popup menu with all open browser windows, the main browser window is at the bottom. With this menu you can switch between open browser windows.

It is possible to configure if you want examinees to be able to use the spell and grammar checker and the macOS dictionary lookup feature. Also availability of page and text zoom can be configured.

SEB detects when it was started in a virtual instead of a native environment and refuses to run. This virtual machine detector hinders manipulating SEB further when used in unmanaged environments.

SEB also detects attempts to switch the user and displays a lock screen afterwards which needs to be unlocked with the quit/restart password by exam supporters/supervisors.

SEB for macOS is based on the WebKit browser engine, which is also used by Safari, Apple Mail and many open source browsers (in contrast to the Mozilla Firefox/XULRunner/Gecko engine used by SEB for Windows). There might be some small differences regarding rendering of web pages in those different browser engines, so you should check all functionality of your quiz in SEB for macOS before using it in exams.

SEB for macOS can be used together with additional (third party) applications during an exam. You can download and open files linked in your online exam, edit it in a third party application and then upload the results to your online quiz/LMS again. Currently this is only possible when SEB is used in a separate user account managed by macOS parental controls.

From version 2.0, encrypted .seb configuration files are used which allow to individually configure SEB per exam.

Also see the how to use SEB 2.0 document explaining the concept behind SEB 2.x and its new features.

Please understand that you also have to configure your exam system correctly to be locked down securely. SEB is generally locking down exam client computers only, not the exam system or the quiz module of a learning management system. Check documentation for your exam/learning management system on how to lock it down correctly.

Some learning management systems require plugins to be installed to fully support secure exams taken with SEB, others have built-in support.

SEB support in Moodle has the following objectives:

  1. Don't display any links during an exam which would allow to navigate to other sections of Moodle or even other websites. This means the course navigation, link to the user's Moodle profile, logout, link to the University homepage etc. needs to be disabled/hidden. Only the quiz navigation (to navigate to other questions) and the "Finish attempt..." link should be visible
  2. Make sure a quiz can only be taken using Safe Exam Browser, display an error message if trying to open the quiz in another web browser.
  3. Optionally check if the correct version of SEB and legitimate SEB settings are used.

There are two options how to activate SEB support in Moodle. Both achieve the above objectives 1 and 2. Only the second option also ensures objective 3 is met:

  1. Enable the "classic" SEB support in Moodle: How to activate the SEB secure browser mode in a Moodle quiz. Then configure the quiz at Administration / Quiz administration / Edit settings / Extra restrictions on attempts / Browser security / Require the use of Safe Exam Browser. This option uses only a basic, not very secure check for the used browser. This may be safe enough if students can only access the exam from centrally managed university computers inside a computer lab/exam room. For other scenarios like BYOD you should use the second option.
  2. Use the Browser Exam Key authentication in Moodle for the connecting SEB version and its settings by installing the quiz access rule plugin in Moodle. In addition you will have to copy the Browser Exam Key hash code string into the quiz settings (Administration / Quiz administration / Edit settings / Extra restrictions on attempts / Allowed browser keys). This key is generated by SEB when you save the settings you intend to use for the exam. As this key includes a hash (checksum) of both the saved exam settings and the code signature of the used SEB version, you may have to generate and copy several Browser Exam Keys into the Moodle quiz settings, for example one for the Windows version of SEB and one for the Mac version.

Sometimes hiding course navigation, link to the user's Moodle profile, logout etc. doesn't work as expected because some custom Moodle themes don't support the secure browser mode of Moodle correctly, they display links with which students can get out of the quiz during an exam. If this happens only with your customized theme and not the standard Moodle theme, then your theme is not implemented correctly. In that case you should fix the problem in your custom Moodle theme. You may also create URL filter rules which only allow to access the exam and no other parts of Moodle, but this is not trivial and we cannot provide you with any support on that.

You may find additional information and help in the discussion boards for SEB and Moodle.

You can find information about how to install the ILIAS plugin for SEB support here.

Please note that currently support for Safe Exam Browser in ILAS can only be switched on for some roles of a whole installation, not a single exam/course.

An assessment mode has been added to the OpenOLAT standard with the 10.2 release. The assessment mode allows course authors to limit the functionality and access of OpenOLAT courses for exam settings. An exam setting is not limited to online tests however, IMS QTI assessments, SCORM modules, external LTI 1.1 tools and all other OpenOLAT course elements can be configured for such an exam setting.

One of the many security features is the enforced usage of Safe Exam Browser. An exam setting can be configured with multiple Browser Exam Key keys.

No additional software needs to be installed in order to use the assessment mode together with Safe Exam Browser. The assessment mode is globally enabled / disabled in Administration -> Modules -> Assessment mode. Within the courses the configuration is done in the course menu.

More information and a video tutorial about the assessment mode.

You can download the DMG disk image file here. If it doesn't get mounted, just double click on the downloaded file. Then drag the SEB application to the Applications folder (you can drop it on the alias icon in the mounted volume). Make sure you don't have another SEB version 2.x on your Mac (as a .seb config file or a seb:// link might get opened with the wrong version).

When you start SEB, all currently running applications are hidden and all attached screens are covered with a black background. On the main screen SEB opens its web browser window filling the whole screen (the window can be resized and moved nevertheless). Optionally you can use a full screen presentation or customize the relative or absolute width, height and horizontal positioning of the SEB main browser window and separately for secondary browser windows.

SEB opens the webpage at the preset Start URL, which might take some seconds. Initially, as long as you don't set another Start URL (see Configuration), SEB for macOS opens the project web site displaying this documentation.

SEB can display navigation buttons in the browser window toolbar (if enabled), and if browsing back/forward has been enabled, you can use cmd-Cursor Left to go back in the browser history and cmd-Cursor Right to go forward in history. Cmd-R reloads the current page.

To quit SEB (while it's using the default settings), just press the quit button in the SEB dock, cmd-Q or the red close button in the browser window. Quitting SEB can (and should in most cases) be password protected in its settings. When SEB quits, the applications which were visible before starting SEB will get unhidden again.

SEB for macOS has a comfortable built-in editor for the platform-independent SEB configuration files, which can also set all additional individual settings for the Windows version. Invoke it by selecting Preferences… in the SafeExamBrowser menu (if visible), by simultaneously pressing the cmd - , (comma) keys, or the F3 and F6 keys (on modern Mac keyboards you usually also have to hold the fn key). After setting a SEB administrator password, users have to enter this to display the preferences window. SEB for macOS can also be configured not to display the preferences window at all, this could make sense on exam client computers.

While the preferences window is displayed, switching to other running (initially hidden) applications is possible and the screen background isn't blacked out. Also the menu bar is displayed, so SEB menu commands can be used. You can also drag and drop .seb configuration files onto the preferences window or the SEB icon in the macOS dock (not the SEB dock). In the preferences window 9 tabs with grouped settings are available.

  • In the General pane you'll find basic settings like the URL which SEB opens and the passwords to enter preferences or open a config file for editing and to quit/restart SEB. When first time using SEB, you might only have to change these general settings, as the default values for all other settings should reflect the more "secure" option.
  • Config File contains details about encryption of the SEB .seb configuration files plus all functions to deal with opening, saving, reverting, duplicating and applying settings. These commands can also be accessed in the Settings menu and the popdown menu in the preferences window title bar (clicking on the triangle symbol).
  • User Interface contains general SEB user interface settings;
  • Browser all detail settings for the built-in SEB web browser.
  • Down/Uploads refers to file downloads and uploads, Exam handles the connection to exam systems and exam specific settings.
  • Application is for handling permitted and prohibited processes;
  • Network about the URL filter, certificates and proxies.
  • Security contains detail settings about how SEB locks down security relevant system features.

There are two different modes in which you can edit settings:

  • Edit local client settings: Changes settings of this SEB client. These local client settings are saved persistently on drive (in the ~Library/Preferences/ directory). When you change a setting option, then it is immediately saved (this is how preferences in other macOS standard applications work).
    In the title bar of the Preferences window 'Local Client Settings' is displayed instead of a file name.
  • Edit a .seb settings file: When you open a settings file, it is always loaded temporary into memory and will be discarded when you quit SEB. So loading a .seb settings file for editing into the Preferences window (which serves as the configuration editor in SEB for macOS, similar to the SEB Config Tool in SEB for Windows) won't change settings of this SEB client permanently. If you change something, you have to explicitly save the changed settings into the same file (using the command Save) or to another file (Save As…).
    In the title bar of the Preferences window the file name of the currently loaded settings file is displayed, together with an file icon. As usual in macOS document windows, you can cmd-click this icon to show the path where the file is saved (as long as it already was saved on drive, see below).

You can switch from editing local client settings to editing a settings file with the commands:

  • Save As… Saves local client settings into a .seb file and if answering the following dialog 'Edit Saved Settings'? with Edit File switches from local client settings to the new file.
  • Edit Duplicate: Switches to editing a settings file (with the default file name SebClientSettings.seb), when saving this config file, the file chooser will be displayed to select a destination directory and to change the file name if desired.

You can switch from editing a settings file to local client settings with:

  • Revert Settings to Local Client Settings: The currently edited settings file is discarded and SEB switches back to editing local client settings.
  • Use Current Settings to Configure Client: Settings from the .seb file which is currently being edited are used to configure local client settings (overwriting current local client settings) and SEB switches to editing local client settings.

When closing the Preferences window, SEB asks if edited settings should be saved (if you were editing a .seb settings file, local client settings are autosaved as described above). SEB also asks if those edited settings should be applied. If you answer Don't Apply, then edited settings are discarded and SEB continues using settings which were in place before opening the Preferences window. If you answer Apply, then SEB reconfigures and restarts itself using those edited settings, and the web page at Start URL is loaded.

If you apply an opened/edited .seb settings file, then SEB is running in the exam mode, same as if SEB is started opening a .seb config file for starting an exam or if the user loaded a .seb config file for starting an exam from an exam portal page. More information about this you can find in the how to use SEB 2.0 document explaining the concept behind SEB 2.x.

Detail description of all parameters in the preferences window panes follows below. You can also use tool tips (move the mouse pointer over a button, text field or other control in the Preferences window) to get a short explanation for the function of the according setting option.

SEB Preferences Window General Pane
  • Start URL: Full URL (starting with http:// or https://) of the page to open when SEB is started.
  • Paste from saved clipboard: SEB saves the content of the clipboard (if it's a text string) when starting up and before clearing the clipboard. Use this link to paste the saved string to the Start URL field.
  • Administrator password: Password required to enter the preferences window or to open a config file for editing. It's recommended to set an administrator password!
  • Confirm administrator password: Retype the administrator password. As long as it's not matching the administrator password typed in the field above, Please enter correct confirm password is displayed below and you cannot save the preferences.
  • Allow user to quit SEB: If selected, Users can quit SEB with cmd-Q or clicking the main browser window (the one that displays the exam) close button. Otherwise you can use a quit link in your exam system, shutdown or reset the computer or use the Quit button in this preferences window. In a computer room in a university or school you could for example use some tool to shutdown or reboot all computers after a exam and therefore not allow students to quit SEB themselves at all.
  • Ignore exit keys (Win): SEB ignores the exit keys and can only be quit manually by entering the quit password. Exit keys can only be set and used in the Windows version of SEB and are considered deprecated, the prefered way to secure SEB from being quit is the quit password.
  • Quit password: This password is prompted when users try to quit SEB with cmd-Q or the red close button in the browser window. If no quit password is set, then SEB just prompts Are you sure you want to quit SEB?
  • Confirm quit password: Retype the quit password. As long as it's not matching the quit password typed in the field above, Please enter correct confirm password is displayed below and you cannot save the preferences.
  • About: Shows a window with SEB copyright information and version number. Click somewhere into the window to close it.
  • Help-Button "?": Displays this manual page in a new browser window.

You can get out of the preferences windows using one of the three buttons described below:

  • Close window (standard red close button in the windows title bar).
  • Restart SEB: Saves preferences, eventually reconfigures and restarts SEB, displaying the webpage at start URL.
  • Quit: Saves preferences and exits SEB.

You can also exit SEB while applying changed settings using the item Apply and Restart SEB in the Settings menu.

SEB Preferences Window Config File Pane
  • Use SEB settings file for ... starting an exam: A config file saved with this option will start the exam with the according settings, but won't change local SEB settings.
  • Use SEB settings file for ... configuring a client: A SEB settings file saved with this option can be used to change local settings of a SEB client. This means, next time the Safe Exam Browser app is started directly (by opening its icon from the Applications folder, the Dock or Lauchpad), it will use these settings. Usually you should encrypt it with the same password which is set as administrator password on the SEB client or none if there is no administrator password set on the SEB client yet. If you use another settings password, then users are promted to enter it.
  • Allow to open preferences window on client: Usually you should disable the preference window on exam clients besides for debugging purposes.
  • Choose identity to be used for encrypting SEB settings file ... In this popup menu all identities (X.509 certificates with RSA public key and associated private key) in your default keychain are listed, which can be used for encrypting and decrypting. Export the chosen identity (in Keychain Access utility) and install it on your SEB clients or embedd that identity into a config file for configuring a client (see Network pane – Certificates section).
  • Settings password: Password to decrypt the config file, if one is set then it will be prompted when SEB reads the settings.
  • Confirm settings password: Retype the settings password.
  • Open settings... Lets you choose a .seb settings file which will be loaded into memory, so you can edit the settings.
  • Save settings (as...) Saves the SEB settings using the same file name or lets you choose a file name and location for the SEB settings file. You have to either enter a password or choose a cryptographic identity with which the SEB settings file will be encrypted. Use the saved encrypted settings file to either start the exam in SEB or to change the local settings of a SEB client, depending on the Use SEB settings file for ... option.

Revert Settings to…

  • Default Settings: After the user confirms, settings are reset to the default settings.
  • Local Client Settings: After the user confirms, revert to the local client settings.
  • Last Saved: After the user confirms, settings are reverted to the last ones saved or loaded.

Use Current Settings to…

  • Edit Duplicate: Creates a duplicate of the current settings and continues editing those.
  • Configure Client: Configures the client using settings from the .seb file which is currently being edited (overwriting current local client settings) and SEB switches to editing local client settings.
  • Apply and Restart SEB: Applies current settings, closes Preferences and restarts SEB.

Local client settings are saved according to macOS standards in the user's Library/Preferences/ directory (~/Library/Preferences/, is by default invisible in Finder). Starting SEB version 2.0, it isn't anymore possible to deploy the org.safeexambrowser.Safe-Exam-Browser.plist file from the Preferences folder to other machines (due to stronger, individual encryption per client). Instead, either deploy and open a .seb config file saved with the option 'Use SEB settings file for ... configuring a client'. This requires user interaction, because SEB will show an alert 'Local settings of this SEB client have been reconfigured. Do you want to continue working with SEB now or quit?' and one of the buttons 'Continue' or 'Quit' has to be clicked. As an alternative, you can use the new pre-configuration feature when deploying SEB on managed systems which works similar like in SEB for Windows (and doesn't require user interaction):

While starting, SEB now checks if there is a configuration file named SebClientSettings.seb in in the Preferences folder (~/Library/Preferences/) and reconfigures itself silently (no user feedback) to the settings in that file, then the file is deleted. This works only if the administrator password in this file matches the one set in the local settings of the SEB client or if there isn't an administrator password set yet in the local settings. This means, if the SEB clients haven't been configured before (because SEB just got installed), you can set an arbitrary administrator password in the SebClientSettings.seb file. The second time you reconfigure SEB clients with this method, the administrator password in the new SebClientSettings.seb file has to match the one used before, otherwise the client won't be reconfigured. The file can either be unencrypted or encrypted with a password that matches the administrator password set in the local settings of the SEB client (otherwise the password to decrypt the settings file will be prompted and the user has to enter it).

In the rare case you would have a problem with the local client settings of a client computer, for example if SEB crashes after starting, you should try to reset the local client settings. Since OS X 10.9 Mavericks this isn't possible by just deleting the org.safeexambrowser.Safe-Exam-Browser.plist file from the Preferences folder, because macOS caches those preferences. Instead use the command defaults delete org.safeexambrowser.Safe-Exam-Browser from the Terminal app shell. Then you should be able to start SEB again, as local settings are reset to the default values (there will be a message displayed indicating that local client settings were reset when you start SEB).

SEB Preferences Window Appearance Pane
  • Use browser window: Use a window for the SEB browser which can be scaled and moved around, also to another screen when available. One advantage of using a browser window is that if you're using a large wide screen display, some web pages may not be ergonomic to read. With the scalable browser window you can adjust the width of displayed web pages.
  • Use full screen mode: Display the SEB browser full screen.
  • Touch optimized (Win): Enables the touch optimized mode for Windows tablet computers (for Windows 8.1 and 10) featuring:
    • Larger buttons in the SEB task bar
    • Touch optimized message boxes (alerts, dialogs) with larger buttons
    • The Winodws on-screen keyboard is displayed when the user touches a text field on a browser page or when SEB asks to enter a password.
    • New web pages open in full screen 'windows', switch between open pages with the open windows chooser popup menu invoked by tapping the SEB icon in the SEB task bar. With the close button below each window in this window chooser you can close open browser full screen 'windows'.
  • Enable touch exit (Win): When enabled, SEB can be quit in touch optimized mode with a swipe down from the upper display edge (helpful when the SEB task bar with the quit button is not used).
  • Automatic on-screen keyboard behavior (Win): Controls when SEB displays the on-screen keyboard.
    • Always show
    • Never show
    • Detect physical keyboard: If a physical keyboard is connected, SEB doesn't show the on-screen keyboard.
  • Main browser window size: You can set the width and height of the main SEB browser window as absolute points (pixel) values or a percentage of the screen width or height. You can enter the dimensions (in points or percent values) in the text field or select one of the predefined values in the popdown menu.
  • Main browser window horizontal positioning: You can choose how the window will be positioned horizontally if it doesn't fill the full screen width: Left, Center, Right.
  • Enable browser window toolbar: Indicaties if a toolbar is displayed on top of the browser window which can also be hidden by the user if it's disturbing. The toolbar containts the back/forward browsing buttons, page and text zoom buttons (if enabled) and the reload button.
  • Hide toolbar as default: After SEB starts, the browser window toolbar is hidden. Users can unhide the toolbar in the view menu or the key combination cmd-alt-T.
  • Show menu bar: Show the macOS menu bar to allow accessing settings like Wi-Fi and for changing keyboard layouts.
  • Show SEB dock/task bar: The SEB dock is displaying an icon for the SEB browser with controls for its open browser windows and a quit button, plus additional optional buttons and information widgets (see below and in the Exam pane for the restart exam button). Clicking the SEB icon in the dock and holding the left mouse button down or a secondary (right mouse button) click displays a popup menu with all open browser windows, the main browser window is at the bottom. With this menu you can switch between open browser windows.
    • Dock height: SEB Dock height in points (pixel height x 2 on Retina HiDPI displays). In SEB for Windows display DPI settings are now also taken in account, in touch optimized mode task bar is scaled up in addition.
    • Show Wi-Fi control (Win): Allows to reconnect to Wi-Fi networks which have previously been connected to.
    • Show reload button: This button in the SEB task bar reloads the current web page. Shows warning if enabled in Browser settings tab.
    • Show time: Displays current time in SEB task bar: This is for example helpful if you decide to ban personal watches in exams (because of smartwatches).
    • Show keyboard layout (Win): Shows current keyboard layout and allows to switch to other keyboard layouts which have been enabled in Windows.
  • Enable page zoom: Pages can be zoomed with cmd +/- or the commands in the view menu and buttons in browser window toolbar (Mac) or with Ctrl-Mousewheel (Win).
  • Enable text zoom: Text in browser windows can be zoomed with ctrl - cmd +/- or the commands in the view menu and buttons in browser window toolbar (Mac) or with Ctrl-Mousewheel (Win).
  • Zoom Mode (Win): Zoom whole web pages or just text using Ctrl-Mousewheel (only in Windows version)
  • Allow spell checking: Allow using check spelling/grammar and 'correct spelling automatically'
  • Allow dictionary look up: Allow looking up text elements on a web site using the 3-finger tap on a trackpad or ctrl-cmd-D
SEB Preferences Window Browser Pane
  • Links requesting to be opened in a new browser window ... This popup list offers three policies:
    • get generally blocked
    • open in same window: This was the behaviour in SEB for macOS versions before 1.5.
    • open in new window
  • Block when directing to a different server: Hyperlinks which direct to a different host than the one of the current page will be ignored.
  • New browser window size: You can set width and height of new browser windows, use "Screen" if you want the window to fill the full width or height of the screen.
  • New browser window size: You can set the width and height of new browser windows as absolute point values or a percentage of the screen width or height. You can enter the dimensions (in points or percent values) in the text field or select one of the predefined values in the popdown menu.
  • New browser window horizontal positioning: You can choose how the window will be positioned horizontally if it doesn't fill the full screen width: Left, Center, Right.
  • Links in JavaScript/plug-ins ... This popup list offers three policies for hyperlinks opened from JavaScript or plug-ins (like Flash):
    • get generally blocked
    • open in same window: This was the behavior in SEB for macOS versions before 1.5, but links got only opened, when they were not directing to a different server (see the checkbox below). USE WITH CARE: When 'open in same window' is selected, then some JavaScript/HTML5 features (like File API) might not work
    • open in new window
  • Enable plug-ins: Enables web plugins like Flash. For security reasons it's recommended to disable this option if you don't use any plugin content.
  • Enable JavaScript: Please note that most modern websites need JavaScript for full functionality.
  • Enable Java: Enables Java Applets. Starting SEB 2.0 this option is disabled by default because Java applets are considered a potential security risk.
  • Block pop-up windows: Disables pop-up windows (often advertisement) opened by JavaScript without an user action such as a button click.
  • Allow browsing back/forward: Disabling browsing to previously visited pages (by cmd - Cursor left) increases security, because it might be possible to leave an exam by browsing back to an external start page.
  • Remove profile (Win): Removes XULRunner browser profile (containing caches and also local storage) when quitting SEB.
  • Disable local storage (Mac): Local storage (which is stored per origin, e.g. the combination of protocol, hostname, and port number as defined in the same origin policy) is meant to persist after a browser is closed. This might be a security issue though if you don't know how securely an exam system is handling information in localStorage. If your web application uses local storage, you have to be sure data is saved encrypted and removed when no longer needed as SEB doesn't remove local storage itself.
  • User agent: Choose browser agent settings for SEB running on various operating systems and device types
    • Default: Default user agent string on this Mac (it depends on installed Safari/WebKit version and therefore can differ on exam clients!)
    • Custom: Enter a custom user agent string (SEB appends its version number automatically)
  • Use SEB without browser window: If you intend to use another application for an exam and don't need to display any web content on the exam client, you can switch off the SEB browser with this option. Don't try to disable XULRunner in the Application -> Permitted Processes tab, that isn't necessary when using this option. This feature is not yet available in SEB 2.1.2.
SEB Preferences Window Down/Uploads Pane
  • Allow downloading and uploading files: Usually to be used when switching to third party applications is enabled.
  • Save downloaded files to: Choose the download directory with this popup menu.
  • Open files after downloading: Downloaded files will be opened with the according application, which has to be set correctly in the system for each used file type!
  • Download directory Windows: Enter a valid, Windows-specific formatted path to a directory which should be used to save donwloaded files.
  • Choose file to upload … SEB can let the user choose the file to upload manually (as usual) or automatically choose the same file which was downloaded before. There are three possible policies to choose the file to upload:
    • manually with file requester
    • by attempting to upload same file downloaded before: If the file is not found, a file requester is presented and the user can choose some other file manually.
    • by only allowing to upload the same file downloaded before: If the file is not found, an error message is presented. This setting might bring additional security, because only files which have been downloaded before (in the same browser session, means since SEB was started) can be uploaded. If several files have been downloaded, pressing the choose file (or similarly named) button in the browser window will first choose the file most recently downloaded, pressing the button several times will cycle through all the files downloaded in this session.
  • Download and open PDF files instead of displaying them inline: PDF files will not be displayed by SEB but downloaded and opened (if Open files after downloading is active!) by the application set in Finder (usually Preview or Adobe Acrobat). This option is useful when you allow to switch to third party applications and want to use some PDF forms which have to be filled out by the examinees/users.
  • Download and open SEB config files: SEB config files are downloaded and opened regardless if downloading and opening other file types is allowed.
SEB Preferences Window Exam Pane
  • Use Browser Exam Key (send in HTTP header): Enables using the Browser Exam Key, it is send in an HTTP header to authenticate the SEB client and its settings to a compatible exam system.
  • Browser Exam Key: Copy this key which depends on your SEB configuration and the SEB version/application signature) to the according field in your quiz settings in the exam system having support for SEB 2.0 or later built in. The Browser Exam Key is automatically re-calculated and displayed in the Exam preferences pane. This happens whenever a setting changes if editing local client settings and after saving a config file if editing settings for starting an exam.
    Important: First save your final exam settings in a .seb settings file and then generate and copy the browser exam key to your exam system's quiz settings as the Browser Exam Key changes when you change any setting.
    Please note that if you want to use the same .seb config file with Windows and Mac clients, you should not alter the file anymore when you're copying the Browser Exam Key hashes to your exam settings in your quiz module. Re-saving it will change the Browser Exam Key of that file also in the SEB version on the other platform. The keys for the Mac and the Windows version will in any case be different, so you have to load the final .seb file into both versions and copy both keys to your quiz settings.
  • Copy Browser Exam Key to clipboard when quitting SEB: SEB clears the clipboard when quitting, so you should either use SEB to copy the exam key to your quiz settings or this option to find the exam key in the clipboard after quitting SEB.
  • Link to quit SEB after exam: Its possible to configure SEB to quit after the exam is submitted without having to enter a quit password by specifying a quit link (full URL starting with http:// or https://) and placing this on the summary page displayed by the LMS after submitting the exam. If a Quit Link is entered, it works regardless of other quit settings in the General pane (Allow user to quit SEB and the Quit password is ignored when a quit link is clicked).
  • Restart exam button: Either check the "Use Start URL" option or enter a link to which the exam is redirected when the restart exam button is pressed. The restart exam button is displayed in the SEB task bar when either the "Use Start URL" option is selected or a link is entered.
  • Title/tool tip text for the restart button: This text is displayed as the title of the confirmation alert and as tool tip on the icon. Leave empty for a standard text (which is localized to the SEB user interface languages).
  • Protect restart exam button with the quit/restart password: The quit/restart password (if set, see General pane) must be entered when the restart exam button was tapped. Exam support/invigilators should be told this password to be able to restart the exam if there is a problem.
  • Monitor processes (Winows): If enabled, SEB monitors which processes/applications are running during an exam. When SEB is started, an alert/dialogue window is displayed to tell the user to quit the currently running applications (which are not in the list of permitted processes) and to restart SEB afterwards or to let SEB kill the applications risking that there could be data loss. Prohibited background processes are killed automatically, without user confirmation. Applications which allow to be terminated nicely in macOS are automatically terminated (also without asking the user).
    clients.

Third party applications and processes which are permitted to run during an exam. Permitted applications show up in the application chooser, they can be used during an exam in addition to the SEB browser.

Using permitted processes is not yet functional in SEB 2.1.2 for macOS. You can define and edit permitted processes for SEB for Windows here.

SEB Preferences Window Applications Pane, Permitted Processes Tab
  • Allow switching to third party applications: If this option is activated, the kiosk mode induced by SEB will be reduced one level. The process switcher (cmd-tab) will work, so it's possible to switch to other running applications.
    Use this option only when running SEB in a user account managed by parental controls, with only SEB and the desired applications allowed. Also you should switch on Simple Finder and don't give users access to other accounts with administrator rights on that computer (see Secure Environment).
  • Allow Flash to switch to full screen mode: Playing videos with Flash in full screen mode is a security problem. That's why it is strongly recommended to use HTML5 video (there full screen mode is no problem) instead of Flash whenever possible. Depending on the Flash video player and the Mac used, it can be difficult to switch back from full screen mode (best is to use the esc key), so if you don't need full screen mode, don't enable it here.
    When switching to third party applications is disabled, Flash fullscreen mode isn't possible at all.

Selected Process details:

  • Active: Indicates if this permitted process item is active (can be used while testing).
  • Title: Application title which is displayed in the application chooser.
  • Description: Optional, should explain what kind of process this is, because this might not be obvious only from the executable's name.
  • OS: Indicates on which operating system the permitted process runs (currently only the option Win works).
  • Executable: File name of the executable, which should not contain any parts of a file system path, only the filename of the exe file (like calc.exe).
  • Window Handling Process: Process executable which is actually handling the main window, this is necessary to indicate for Java and some other applications (for example OpenOffice, Eclipse, Adobe Acrobat).
  • Path: Optional filesystem path (formatted system specific) to the process executable's directory excluding the filename, see field executable. If the path is not given or relative, then SEB searches the system provided paths for applications. For applications which have been installed and properly registred in Windows App Paths you don't need to specify the path.
  • Arguments to append to the executable of the application when starting it. You can select if an argument is active or not (for testing). You can add and remove arguments using the +/- buttons.
  • Icon in task bar: Mainly useful for background processes (not requiring user interaction) which you want to autostart when SEB is run.
  • Autostart: Start the process automatically together with SEB.
  • Identifier: String of the process identifier in reverse domain notation (Mac) or the string or substring of the main window title of a process which doesn't have a MainWindow handle (Win), this is usually the case with Java applications (use for example "OpenOffice" for OpenOffice Calc).
  • Allow running in background: Permitted processes with this option set are allowed to already be running when starting SEB. In this case SEB doesn't ask the user if the process can be terminated before continuing to start SEB. Processes with the option "Allow running in background" don't have an icon in the SEB task bar. They can nevertheless have the option "Autostart" set, in this case SEB attempts to start the permitted process regardless if it was already running or not (and the option "Icon in task bar" is considered in this case).
    If you need some background process running together with SEB and this process might display some window or alert/message box, you have to add this process's executable to permitted processes with the option "Allow running in background" set, otherwise SEB will hide the window of the background process when "Monitor processes" is selected (or even terminate that process, in case it cannot be hidden).
  • Allow user to select location of application: The user is presented a file dialog window allowing to locate the third party application's executable if it cannot be found at the path specified and paths provided by the system (instead of just displaying an error message). Only applications matching the executable string specified are accepted.
  • Force quit: Indicates whether an application/process may be terminated in a not-nice way, what may cause data loss if the application had unsaved data in memory or was just writing to a persistent memory/drive. If this application is safe to be terminated anytime, then enabling this setting helps to avoid bothering users: Because if this setting is disabled and the application is running when SEB is started, then an alert/dialogue window is displayed to ask the user to quit this permitted application together with other permitted and the prohibited applications and to restart SEB afterwards (or to let SEB terminate the applications risking that there could be data loss).
    Disabling this setting does not mean that processes are not killed: Depending on the platform's capabilities, SEB first tries to terminate prohibited processes and applications nicely or asking the user to do it themselves, if this doesn't work then it terminates them anyways (as long as monitor processes is enabled). But enabling Force quit will speed up this process.
    This flag should not be set for macOS applications which allow to be terminated nicely (they are anyways automatically terminated, without asking the user).

Java applications (like OpenOffice) can be used as permitted processes, but require specific settings: The title of their main window must be defined in the field Permitted Processes -> Identifier (for example "OpenOffice Calc"), the required main executable in Permitted Processes -> Executable ("scalc.exe") and the process which is actually handling the main window in Permitted Processes -> Window Handling Process(es) ("soffice.bin"). For this example the executable path should be entered as "program" in Permitted Processes -> Path, as that is the relative path to the main executable from the OpenOffice main directory, which is registered in Windows App Paths.

List of processes which are prohibited to run during an exam when monitor processes is enabled. This prohibited list of processes makes sense because SEB usually allows to run system processes (SEB for macOS allows all processes and applications signed by Apple to run), but some of them might not be wanted during an exam. With prohibited processes you can prevent some specific background processes and applications from running together with SEB. Use this with care, test if the system continues to run safely when the prohibited processes are killed by SEB.

Using prohibited processes is not yet functional in SEB 2.1.2 for macOS. You can define and edit permitted processes for the Windows version of SEB here.

SEB Preferences Window Applications Pane, Prohibited Processes Tab

Selected Process details:

  • Active: Indicates if this prohibited process item is active.
  • Executable: Process name, usually the filename of the executable.
  • Description: Optional, should explain what kind of process this is, because this might not be obvious only from the executable's name.
  • OS: Indicates on which operating system SEB should watch for the prohibited process (currently only Win works).
  • Identifier: String of the process identifier in reverse domain notation (Mac) or the string or substring of the main window title of a process which doesn't have a MainWindow handle (Win), this is usually the case with Java applications (use for example "OpenOffice" for OpenOffice Calc).
  • Force quit: Indicates whether an application/process may be terminated in a not-nice way, what may cause data loss if the application had unsaved data in memory or was just writing to a persistent memory/drive. If this application is safe to be terminated anytime, then enabling this setting helps to avoid bothering users: Because if this setting is disabled and the application is running when SEB is started, then an alert/dialogue window is displayed to ask the user to quit this prohibited application together with permitted applications and to restart SEB afterwards (or to let SEB terminate the applications risking that there could be data loss).
    Disabling this setting does not mean that processes are not killed: Depending on the platform's capabilities, SEB first tries to terminate prohibited processes nicely or asking the user to do it themselves, if this doesn't work then it terminates them anyways (as long as monitor processes is enabled). But enabling Force quit will speed up this process.
    This flag should not be set for macOS applications which allow to be terminated nicely (they are anyways automatically terminated, without asking the user).
SEB Preferences Window Network Pane, Filter Tab
  • Activate URL filtering: Filter URLs when loading web pages using the filter set defined below.
  • Filter also embedded content: If selected, also all embedded ressources will be filtered using the filter set. Note that there can be hundreds of resources such as images and other media per page, so filtering all content may slow down page loading.

The table contains URL filter rules, consisting of a allow or block action. The URL filter always first processes rules with the block action, if one matches, then the according http request is discarded. If no block rule matched, then rules with an allow action are processed. If one matches, then the request is loaded. If no allow rule matched, then the request is discarded.
Discarding a http request means that a link with the URL is not followed and the user is notified with an alert. When content filtering is enabled, an embedded resource with the according URL is not loaded, in this case there's no notification about that, but it is written to the log (log level Warning on Mac). Create a new rule by clicking the'+' button below the table. Remove a rule by selecting it in the table and clicking the '-' button.

SEB automatically creates an allow filter rule for the exact address of the Start URL defined in these settings. This means that if your Start URL is example.com, then all pages and resources in the domain example.com will be allowed. If your Start URL is example.com/exams/engineering2015-1.html, then only the pages with this exact address will be allowed. In this case you have to manually add an allow filter rule so all pages and resources your exam uses will be allowed (like example.com/exams/*).

Rules

  • Active: Indicates if the rule is active.
  • Regex: Indicates if the rule is a regular expression.
    If Regex is not checked, then the rule can be formatted using the wildcard '*', which stands for an arbitrary string of any length.
  • Action to process if the corresponding expression matches. Possible actions:
    • block
      If the URL matches the expression, then it is rejected and processing of the remaining rules is stopped.
    • allow
      If the URL matches the expression, then it is accepted and processing of the remaining rules is stopped.

    If the URL filter reaches the last rule (means there was no matching block or allow expression found), then the URL is discarded. If you want the URL to be accepted if no matching block (or allow) expression was found, then add an 'allow *' expression.
  • Expression: A Text field which contains the filtering expression or pattern, either in a regular expression (Regex) format or a simpler filter expression containing the wildcard char '*'. A filter expression can filter against all elements of a URL/URI according to RFC 3986:

    scheme://user:password@host:port/path?query#fragment

    Format for a filter expression in the non-regex format:
    • Scheme is optional, and must be followed by '://'.
    • The host field is required (besides when filtering against a protocol like about:blank or data:), and is either a partial or full hostname or an IP address. It can also contain or be replaced completely with the wildcard '*' char, see below for details. The URL filter doesn't resolve hostnames itself, so if you allow everything and only block 'hostname.com', then that host could still be reached using its IP address. You should therefore mainly use whitelisting to allow accessing only specific sites during an exam.
    • An optional '.' (dot) can prefix the host field to disable subdomain matching, see below for details.
    • An optional port can come after the host and always has to start with the character ':'. It must be a valid port value from 1 to 65535.
    • An optional path can come after the host or after the port and always has to start with the character '/'. Parts of the path can be replaced with the wildcard char '*'. If a path ends with a '/', that trailing '/' is removed (as the filter doesn't distinguish paths with or without trailing '/').
    • URL parameters like a query string can be indicated and always have to start with the character '?'. Parts of the query can be replaced with the wildcard char '*'.
    • Filtering against a fragment usually doesn't make sense, as the content can be reached by scrolling the loaded page. Allowing specific fragments could force people to use a link to a particular anchor on a page (other links would not work).

      Examples for filter expressions:
    • 'example.com' matches 'example.com', 'www.example.com' and 'www.mail.example.com' (internally processed as a host name search for 'example.com' and a search for '*.example.com')
    • '.www.example.com' matches exactly '*://www.example.com' (no other subdomains)
    • 'mail.*' matches all hosts having a subdomain or domain 'mail', like 'mail.ethz.ch', 'www.mail.gov.to', 'mail.com'
    • '*:8088' matches all requests to port 8088
    • 'example.com/stuff/*' matches all requests to any subdomain of 'example.com' that have 'stuff' as the first segment of the path
    • 'example.com/images/*.png' matches all requests to any subdomain of 'example.com' that have '/images/' as the first segment of the path and '.png' as the path extension of an file URL (means it matches all PNG images in the '/images/' directory or its subdirectories)
    • '*.net' matches all host with any kind of subdomains in the .net top level domain like 'example.net', 'www.example.net', 'www.mail.example.net'
    • '*/*.net' matches all files with a '.net' file extension on any host

      You should consider using a regular expression if performing complex filtering (when a simple filter doesn't cover all possible cases how that complex URL could be formatted) or split the expression into several filter rules. The order of filter rules is not relevant.

SEB Preferences Window Network Pane, Certificates Tab
  • Choose TLS/SSL certificate to embed into settings: Lists valid TLS/SSL certificates from the macOS keychain (if a TLS/SSL certificate isn't listed here, use the "Advanced…" option below). Selected certificates will be included into a .seb settings file when it is saved and used on the SEB clients which are started up with that .seb exam configuration. Users then won't be presented a warning when connecting to https servers with self-signed certificates and you don't need to distribute TLS/SSL certificates manually to the exam client computers.
  • Choose CA certificate to embed into settings: Lists valid certificate authority certificates from the macOS keychain (if a CA certificate isn't listed here, use the "Advanced…" option below). Selected certificates will be included into a .seb settings file when it is saved and used on the SEB clients which are started up with that .seb exam configuration. Users then won't be presented a warning when connecting to https servers with certificates which rely on a certificate authority which isn't included in the system's root certificate store. You don't need to distribute CA certificates manually to the exam client computers when embedding them into a SEB config file.
  • Pin embedded certificates: If this option is selected, the certficate store of macOS isn't used to evaluate the validity of a server certificate when SEB connects to a secure server using https. You have to embed TLS or CA certificates into SEB settings which establish trust for the secure servers you want SEB to connect to. The used certificates must be valid (not expired, containing the server's host address in "common name" or "alternative names"). If you want to use a certificate which fails validation (for the mentioned reasons), use a "Debug Certificate" which you can add in the "Advanced" window, where you can override "common name" and "alternative names" by changing the displayed name of the certificate into the server's host address (you can also specify a non-default port number).
    If "Pin embedded certificates" isn't selected and you embed TLS, Debug and/or CA certificates, these
    certificates extend the system trust store (as if you had manually added them to the system trust store)
  • SEB only supports embedding TLS/SSL and CA certificates and using certificate pinning if running on macOS 10.9 or later versions. If you want to make sure that embedded certificates and certificate pinning work on all exam clients, then you should enforce the minimum macOS version 10.9 in the Security pane.
  • You can also choose cryptographic identities from the keychain which are suitable for decrypting .seb files on SEB exam clients (X.509 certificates with RSA public key and associated private key). Those will also be added to the .seb settings file. Use this feature for creating a .seb file for configuring a client and add the identity or identities you like to use for encrypting SEB config files for starting exams later. Thanks to this feature you won't need to export the identities in Keychain Access and install it on your SEB clients manually.

In this pane you can configure proxy settings for the exam client computers which override the system's proxy settings on the clients. Using those SEB proxy settings is not available in SEB 2.1.2 for macOS, you have to set proxy settings in System Preferences / Network on each client computer. SEB 2.1 and newer for Windows supports individual proxy settings which you can configure here.

SEB Preferences Window Network Pane, Proxies Tab
SEB Preferences Window Security Pane, System Lockdown Tab
  • SEB Service policy: The SEB Service is a background process running with elevated privileges (with administrator rights), which is necessary to block and unblock some system features. You can define the policy that applies when the SEB Service isn't running (for whatever reason):
    • allow to use SEB without service: SEB is allowed to run without the SEB Service, it will only be noted in the log that the service was not securing the computer during the exam.
    • warn when service is not running: A warning is displayed when the service is not installed/running, but the exam can be started.
    • allow to use SEB only with service: SEB is only allowed to run when the SEB Service is installed.
    SEB for macOS doesn't use a SEB Service. This setting has an effect in SEB for Windows only.
     
  • Allow SEB to run inside virtual machine: Indicates if SEB is allowed to run in a virtual machine (e.g. for exams in virtual desktop environments) or not (in order to prevent potential manipulations).
  • Allow screen sharing: Allows macOS screen sharing to be used. If this option isn't enabled, SEB shows an alert and refuses to start up. If screen sharing is detected while SEB is running, a red lock screen is displayed and SEB can only be unlocked after the screen sharing session has been stopped and then the restart/quit password is entered (therefore exam supervision/support should know this password!).
    To avoid that SEB locks itself during an exam when it detects that screen sharing started, it's best to switch off 'Screen Sharing' and 'Remote Management' in System Preferences/Sharing.
  • Enable screen capture: Controls macOS screen capture (invoked with cmd-shift-3 and cmd-shift-4), corresponds with Enable Print Screen in Windows. If users have the DropBox client installed and activated to upload screen shots directly to their DropBox, then this will also be stopped when screen capture is disabled.
  • Use private clipboard: Prevents utilities running in the background and Universal Clipboard (on macOS 10.12 Sierra) to be used to copy-paste contents into or out of exams. Private clipboard should always be used besides when working with third party applications in a managed user account.
  • Enable logging: The log can help in debugging SEB (if you send it to the developers) and to find out about possible manipulations. You can save the log to a network drive mounted on all exam client computers, since the log's name is unique and contains the machine's name and IP address.
  • Log level: The log level indicates which information gets saved. Error includes fatal application and browser level errors, Warning are non-fatal but non-expected or security affecting events. Info includes most user actions including all browser navigation actions like addresses of opened web pages. Debug is reserved for information which is only necessary for in-deep program code debugging. The log will contain the selected log level plus all levels with a lower value, a log with the Verbose level contains events of all levels.. Default is Warning (error and warning messages). Debug and Verbose are meant for debugging (send such a log file to the SEB developers to find out details about a problem).
  • Save log file to: Choose the directory where to save the log to. You could also save the log to a network drive mounted on the exam client computer.
  • Use standard directory: The log is saved to the directory ~/Library/Logs/Safe Exam Browser/ which is also displayed in the Console app log list.
  • Log file directory Windows: Enter a valid, Windows-specific formatted path.

OS Specific Settings: macOS

  • Enforce minimal macOS version: This is helpful if your web application isn't compatible with an older WebKit version (as for example used in OS X 10.7) or if you want to make sure that embedded certificates and certificate pinning work on all exam clients. In the latter case you should enforce the minimum macOS version 10.9.
  • Disable app switcher when starting: SEB checks for the command key being held down while SEB is starting up. This prevents using the application switcher to mess with SEB's kiosk mode.
  • Force installation in Applications folder: SEB enforces to be installed in an Applications folder (/Applications or ~/Applications).
  • Allow display mirroring (affects also AirPlay Display): If not selected, SEB prevents to mirror the main display to another (for example an AirPlay Display).
  • Maximum allowed number of connected displays: If more displays are connected, these are blanked with an orange full screen window. Disabling display mirroring and allowing only one display can prevent wireless displays be used to cheat or leak exam content.
  • Use built-in display: Use the built-in display (if available) when only one display is allowed or when switching off display mirroring.

OS Specific Settings: Settings for SEB Windows

  • System Lockdown: The Kiosk mode settings reflect how the computer is locked down while SEB is running, see Windows manual for details.
  • Registry: Select which options in the Windows Security Screen invoked by Ctrl-Alt-Del should be available while SEB is running (switch user, lock this computer, change a password, start Task Manager, log off, shut down, ease of access). In addition the Registry setting Enable VMware Client Shade activates the 'Shade' bar at the upper edge of a virtual desktop. If you're not using VMware, this setting doesn't have any effect.
  • Hooked Keys: Here you can select which special and function keys are blocked or enabled. Note: Enable Print Screen corresponds with Enable screen capture in macOS (changing one settings also changes the other). Same as in macOS, if users have the DropBox client installed and activated to upload screen shots directly to their DropBox, then this will also be stopped when Print Screen is disabled.

SEB for macOS is running on 64-bit Intel Macs with the following operating systems:

  • macOS 10.12 Sierra
  • OS X 10.11 El Capitan
  • OS X 10.10 Yosemite
  • OS X 10.9 Mavericks
  • OS X 10.8 Mountain Lion (TLS/SSL/CA certificate embedding and certificate pinning not supported)
  • OS X 10.7 Lion (only supported as client, preferences window not available. TLS/SSL/CA certificate embedding and certificate pinning not supported)
  • Mac OS X 10.6 Snow Leopard (only supported up to SEB 1.5.2)

As mentioned, it is more secure to use SEB for macOS in a managed environment, for using third party applications it's generally required. When you create a separate user account with the settings described below, you can achieve a really secure environment.

  • Create a Standard or Managed with Parental Controls user account (System Preferences -> Accounts). For running third party applications together with SEB, you have to use an account managed by parental controls.
  • You can add SEB to Login Items in the Account Preferences, then SEB will be started automatically after the exam user logs in.
  • In Login Options you should uncheck the checkbox in front of Show fast user switching menu as, at least when the examinees have access to other accounts on that computer.
  • If you use an account with parental controls and third party applications, you can set (System Preferences -> Parental Controls) the option Simple Finder and Only allow selected applications with only SEB and the desired third party applications selected and in the Web tab Allow access to only these websites the URL to your LMS server.
  • In System Preferences -> Sharing you should switch off everything, especially Screen Sharing, File Sharing, Remote Login, Remote Management and Internet Sharing. Or protect everything with proper passwords and don't give users administrator rights on that computer.
  • Enable Open Firmware Password: The Open Firmware password is a security feature available on modern Macintosh systems. If you enable the Open Firmware password, the computer will execute a secure boot sequence. Specifically, enabling the Open Firmware password prevents users from starting up the computer from a volume other than the chosen as the startup disk (chosen in the Startup Disk preference panel within the System Preferences.) Also, enabling the Open Firmware Password prevents users from booting into single user mode using Command-S key combination at boot time. An administrator can enable the Open Firmware password booting up from the restore partition (hold Cmd-R while powering computer up) and using the Set Firmware Password menu option. In OS X 10.7 you need to use the Firmware Password Utility application that can be copied from the macOS software installation disc (located at /Applications/Utilities/ on the disc, not visible in Finder, use the Terminal).
    The Open Firmware Password will be reset if a user changes the amount of the physical memory in the machine and reboots. Systems which require Open Firmware Password level security need to be protected from users gaining physical access to the internals of the computer.
