Safe exam browser linux

About Overview

Concept

Safe Exam Browser is a web browser environment to carry out e-assessments safely. The software turns any computer temporarily into a secure workstation. It controls access to resources like system functions, other websites and applications and prevents unauthorized resources being used during an exam.

General Concept

SEB runs on a local computer and it is connected via the internet to a learning management system (LMS) or an e-assessment system. Generally SEB works with any web based LMS and other kinds of web based exam systems. Some learning management systems (LMS) like for example Moodle, ILIAS, OpenOLAT and exam solutions as Inspera Assessment offer a quiz mode specifically compatible with SEB.

Architecture

SEB consists of a kiosk application and a browser part, which are running on an examination computer or tablet device. The kiosk application locks down the examination computer, the browser part communicates over the internet (or a LAN) with the quiz module of an LMS running on a server.

Schematic illustration of an online exam with Safe Exam Browser and a LMS, for example ILIAS or Moodle. In addition a third party application can be allowed to run at the same time, for example Excel or R

Components

The illustration above shows the two internal components which SEB consists of, the kiosk application and the browser part. The third part of an SEB exam environment is build into the supported LMS. Optionally one or several third party application(s) can be allowed to run during an exam and are started by the SEB kiosk application.

1. The kiosk application locks down the computer and starts the SEB browser plus optional third party applications. Since this application has to control miscellaneous OS functions, it is designed very system specific.
2. The SEB browser loads and displays the LMS exam page using a preset URL and doesn’t show any navigation elements like address bar, search engine field etc. The Windows version of SEB currently uses the Mozilla Gecko browser engine, either in the form of Firefox or XULRunner. SEB for macOS and iOS use the WebKit browser engine.
3. The learning management systems contain so-called quiz modules, which are used for online exams. SEB relies on extensions/skins to the quiz modules in Moodle and ILIAS for secure exams. With these extensions the user interface of the LMS is reduced to just contain navigation for the exam (no links to other pages outside the quiz) and no other undesirable features like messaging. An exam can also be configured to run only with SEB, not another browser. These SEB LMS extensions, which originally had to be installed separately to achieve this connectivity with SEB, have been integrated into the LMS in recent versions of ILIAS and Moodle.

SEB for Windows

Safe Exam Browser for Windows consists of the SEB kiosk application, which opens an own Windows desktop and blocks system commands like keyboard shortcuts (for example ALT+F4) and right mouse button clicks. The second part is Firefox, running in a so-called XUL runtime mode. The SEB XUL browser application running on Firefox connects to the LMS, using a pre-configured start URL. The SEB browser doesn’t contain a URL or search field and navigation controls (back/forward, reload) can be disabled.

SEB for macOS and iOS

In contrast to the Windows version, Safe Exam Browser for macOS and iOS is a monolithic application using a web browser framework instead of a browser runtime. It’s using the WebKit engine, on which Safari and some open source browsers are based. Otherwise, SEB for macOS/iOS connect to the Learning Management Systems in the same way as the Windows version.

Configuration

Safe Exam Browser enables secure exams on unmanaged computers like students’ own laptops and tablets as well as in managed environments on all three platforms Windows, macOS and iOS. Starting version 2.0, SEB offers an individual configuration per exam, which is protected by a strong encryption against manipulation. Thanks to an elaborate authentication feature, the exam system can verify that a particular, unaltered SEB version and the correct exam settings are used for an examination. This facilitates secure exams especially on unmanaged computers like students’ own laptops/tablets.

Safe Exam Browser 2.0 and later is a unified version which brings almost the same features, exam system interface, compatible configuration files and a very similar user interface onto all three platforms, while still taking in account operating system differences and unique platform specific features.

Privacy Statement

SafeExamBrowser (SEB) doesn’t send any personal information to any centralized server and is not connected to any web analytics, user tracking or clickstream analytics service. Some data which can be considered to be personal (computer host name, computer account user name, some URLs of opened web pages etc.) can be contained in the log files SEB saves on the system it is running on (when used with default settings). Log files are not transmitted to any server by SEB, you can manually collect those log files for debugging purposes. Logging can be switched off in SEB’s settings (Win/Mac). SEB is not collecting other user data, SEB is basically only displaying web pages as any other web browser and therefore doesn’t «know» details about exam users. As SEB can be used with various web-based examination systems, you have to make sure that those systems protect the examinees’ data.

There is no registration whatsoever required when downloading, installing or using SafeExamBrowser. SEB is not connecting to any cloud service or server, besides the web server which you enter as «Start URL» in your settings. When started with default configuration, SEB for Windows/macOS displays this page

As SEB is open source, anybody can review the code to verify that SEB really doesn’t connect to any centralized servers and is not sending any collected user data. Additionally, SEB for iOS contains a security module to verifiy the integrity of the SEB application and the iOS environment. This module is only distributed in binary form and for security reasons its source code is not available as open source. This module doesn’t collect or send any personal information to any centralized server, it is not accessing the network or the Internet.

Windows Legacy

Safe Exam Browser 2.4.1 for Windows 7, 8.1 and 10
SHA1: aec3ef8a45a40942f8675e7ab77b896e1ce05dba

SEB 2.4.1 for Windows is a maintenance release, which can be used if the refactored, more modern version SEB 3.0.1 misses a feature you need. SEB 2.4.1 fixes an issue which was reported to happen when using the SEB-Moodle Deeper Integration (available by default in Moodle 3.9 and as plugin for Moodle 3.7 and 3.8).

Please note our new update policy: We will only support the latest SEB version and will remove all older SEB versions after a grace period. Only with updated SEB versions you can achieve the best possible security and stability of e-assessments. Before asking any support question or reporting a bug, install the latest SEB version and try to reproduce the issue with the most recent version. We can’t answer questions anymore when the SEB version isn’t mentioned or when you don’t confirm you tried it with the current version.

• Fixed issue when the old browser window stayed open while reconfiguring with seb(s) link, together with the Firefox file open dialog. Should fix issues when using SEB-Moodle Deeper Integration.
• Implemented fix for VMware Windows Registry error: The Registry value for «Enable VMware Client Shade» will now only be set if the active configuration explicitly says so (see new setting in SEB Config Tool / Registry / «Set VMware configuration». Don’t enable this setting if you are not running SEB in a VMware Horizon View virtual desktop.
• Added Zoom to list of prohibited applications. If you want to use Zoom together with SEB, you have to set its «Active» property to false (Applications / Prohibited Processes).
• Added expansion of environment variables in path of permitted processes. This allows to configure applications to run as permitted process, which need to be installed in subdirectories of the user directory, for example %AppData%.

New since SEB 2.4:

• Config Key feature, hash checksum value to verify settings used by SEB. The Config Key can be generated automatically by a compatible exam system together with the SEB config to be used for an exam. All SEB versions supporting the Config Key generate the same key, as long as the same SEB config file is used.
• Implemented setting keys to control clearing cookies when starting/ending a session (examSessionClearCookiesOnStart / examSessionClearCookiesOnEnd). This can be used to keep users logged in (SEB started with client settings) after an exam session was started.
• Now TLS 1.2 is supported for downloading .seb files using sebs:// links.
• Added more default prohibited processes.
• Private clipboard should now also work correctly with rich-text editors like TinyMCE (fixed double pasting of text).
• Additional bugfixes.

See release notes for all changes.

• Using the powerful feature «Additional Resources», external and embedded webpages, full or partial websites, HTML5 web applications and PDF documents can be accessed securely and easily in exams using icons in the SEB task bar (similar to permitted applications) or hierarchical popup menus.
• Support for encrypted .seb setting files which allow to individually configure SEB per exam. The configuration is compatible with the Windows, Mac and iOS versions of SEB. Use the separate SEB Windows configuration tool to create .seb settings.
• Buttons in the SEB task bar for back to start, reload page, change keyboard layout, switch Wi-Fi network, change audio volume and a display for the current time improve usability in exams.
• Feature to quit SEB after the exam is submitted by specifying a quit link and placing this on the summary page displayed by your LMS after submitting the exam.
• The Browser Exam Key allows an exam module to authenticate the connecting SEB version and its settings. Plug-ins offering this functionality have been released for the learning management systems Moodle and ILIAS, OpenOLAT from version 10.2 has built-in support.
• Configurable options (per exam) in the user interface: Size and positioning of browser windows (main window with the quiz and additional browser windows) can be preset. The SEB main browser window can be displayed full screen or as a sizable and movable window.
• Permitted third party applications are easy to start and to switch to (autostart together with SEB and by clicking on its icon in the SEB task bar). Prohibited processes and applications can be defined which are closed when SEB starts up. SEB contains a list of default prohibited processes too.
• PrintScreen can be blocked, the clipboard is cleared when SEB is started and stopped.
• Security feature which monitors processes and hinders all non-permitted applications to open, become active and display windows while SEB is running.
• Individual proxy settings, URL filters and server certificates can be used per exam.
• SEB config files saved for configuring a client can contain embedded cryptographic identities (X.509 certificates with private key) which will be installed in the Windows Certificate Store and then can be used to decrypt .seb config files without having to use a settings password.
• Screen saver and idle sleep are paused while SEB is running to prevent having to enter an screen unlock password before the exam starts.

SEB configuration editor for creating and modifying .seb settings files for Safe Exam Browser:

• Allows to define all options for the Windows and Mac versions of SEB 2.x.
• Can save .seb files for individual configuration per exam and per exam client, which are protected by strong encryption against manipulation.
• Configuration files can configure a SEB exam client to show for example a portal page with the current exams.
• Configuration files can be used to start an exam with individual configuration (like specific security and user interface options, permitted third party applications and additional resources, Browser Exam Key for authenticating these settings and the SEB application to an exam server, Quit Link to close SEB automatically when an exam is submitted etc.).
• Supports .seb files encrypted with password or X.509 (public/private key cryptography) certificates. For debugging purposes .seb configuration files can be saved unencrypted in an human readable XML format.

See release notes for all changes and read the manual for more information.

macOS

Current version of Safe Exam Browser for macOS 11, 10.15, 10.14, 10.13, 10.12, 10.11 (limited support* for 10.10, 10.9, 10.8 and 10.7)
Build 3140. SHA1: b5fa2826411aa8e8448b26ec8aa28d2d5c50aad4

SEB 2.3.2 is a minor update for 2.3.1 with one bug fix:

• When running on macOS 11 Big Sur on Intel CPU based Macs (tested on macOS 11.2.3), system processes displaying UI in the foreground were not recognized as system applications and terminated by SEB or locked SEB (displaying a red lock screen) if SEB couldn’t terminate them. Now system processes should be identified correctly both on Intel and Apple Silicon based Macs.
• SEB 2.3.1: Changed default setting for AAC to disabled, using a new settings key enableMacOSAAC.

SEB 2.3 added new capabilities, improved the user interface for students and exam administrators and fixed several issues:

Support for Automatic Assessment Configuration (AAC) macOS Assessment Mode. AAC can be used optionally if running on macOS 10.15.4 or newer. Assessment Mode blocks various macOS features which shouldn’t be accessible during exams. Also no other applications and processes running in the background can access the network while Assessment Mode is active.

By default, the old SEB kiosk mode is still used also on latest macOS versions (see Preferences / Security / «Use Assessment Mode (AAC) if available», settings key enableMacOSAAC), as AAC doesn’t support optionally enabling features like like screen capture/sharing, Siri and Dictation. Assessment Mode also cannot be used if you want to run a video conferencing solution in the background during an exam for proctoring.

New options to enforce using the internal (built-in) display of a MacBook or iMac but optionally still allowing to use the external display on a Mac without built-in display (Mac Mini, Mac Pro).

Fixed an issue when calculating the Config Key for configuration files containing prohibited processes entries for both macOS and Windows.

New battery indicator in the SEB Dock, automatically displayed on devices with battery when the macOS menu bar with its battery indicator is disabled. This specifically applies when using Assessment Mode, as then the menu bar is always hidden.

Full compatibility with macOS 11 Big Sur.

Native support for Apple Silicon (universal binary).

Preferences window can be opened by holding the option/alt key when starting SEB (also when dropping a SEB configuration file onto the SEB icon).

Fixed drag-and-drop of configuration files onto the Preferences window. Note that files in iCloud drive need to be downloaded first (click the cloud icon in Finder’s list view).

Added SEB 3.x for Windows settings to the Preferences window.

Improved starting SEB by opening settings, fixed some related issues.

Improved workaround for SEB freezing when a webpage tries to download a font.

• Support for encrypted SEB setting files (file type .seb ) which allow to individually configure SEB per exam. You can use the same .seb files for starting exams on SEB Windows clients and SEB clients on macOS.
• Comfortable built-in editor for the platform-independent SEB configuration files, which can also set all additional individual settings for the Windows version.
• SEB features an optional dock/task bar displaying an icon for the SEB browser with controls for its open browser windows, additional buttons and display widgets.
• SEB can easily be quit after the exam is submitted by specifying a quit link and placing it on the summary page displayed by your LMS/exam system after submitting the exam.
• The Browser Exam Key allows an exam module to authenticate the connecting SEB version and its settings. Plug-ins offering this functionality have been released for the learning management systems Moodle and ILIAS, other systems have built-in support: OpenOLAT, Inspera Assessment and others.
• User interface can be customized: Size and positioning of browser windows (main window with the quiz and additional browser windows) can be preset. Main window can be displayed full screen. An indicator shows network activity.
• SEB can optionally display the standard macOS menu bar and a tool bar in browser windows, functions like ‘About SEB’, quit, open preferences, reload page, zoom page/text and browsing back/forward are therefore easier accessible.
• Enhanced URL filter including teaching mode to control access of the SEB browser to web links and resources. Saved settings files contain URL filter rules which also work in SEB for Windows.

See release notes for all changes.

* Please note: On macOS 10.7 — 10.10 SEB can only be used as an exam client, the preferences window is not available. Run SEB on macOS 10.11 or higher to create a .seb configuration file to configure SEB clients running on older macOS versions as well. With default settings, SEB 2.3 runs only on macOS 10.11 El Capitan or newer (as macOS 10.10 or older provide a clearly outdated and less compatible WebKit browser engine). You can change this setting if you want students to be able to use older macOS versions.

Current version of SafeExamBrowser for iOS/iPadOS 11 and newer

The major update SEB 3 for iOS supports the modern WebKit browser engine, access to camera/microphone via WebRTC on iOS 14.3, SEB Server and live remote proctoring.

New in SEB 3.0.1 for iOS:

• SEB 3.0.1 runs by default on iOS/iPadOS 15
• Fixed that a custom user agent and suffix wasn’t updated when reconfiguring SEB.

New in SEB 3.0 for iOS:

• Support for the modern WebKit browser engine, which increases performance, stability and compatibility with web applications.
• Access to camera/microphone via WebRTC on iOS 14.3 or newer.
• SEB 3.0 for iOS can now also be started with seb(s) links to servers requiring authentication (including Basic Auth).
• With the SEB integration in Moodle 3.9 or newer, you can now use the «Launch Safe Exam Browser» button to open the quiz in SEB for iOS.
• SEB JavaScript API, currently for querying app version details, ConfigKey and BrowserExamKey security elements.
• Live remote proctoring using the free, open source video conferencing solution Jitsi Meet. You can use any Jitsi Meet server to test this feature, for example https://meet.jit.si (or install your own Jitsi Meet server).
• AI (machine learning) supported proctoring detects if candidates disappear from the camera view or if other faces show up. Also suspicious face movements are detected and displayed with warning symbols in the video stream. The face tracking features work on-device and respect privacy.
• Support for SEB Server: In the web backend of SEB Server, an administrator can import exam metadata from a learning management system (LMS) and create SEB Server exams. The list of current exams is then displayed on the SEB clients connected to this SEB Server instance. During the exam, the clients can be monitored in the SEB Server web backend, SEB can be quit remotely etc.
• Both Jitsi remote proctoring and SEB Server require examination administrators to set up their own server instances (or use external service providers) and configure SEB clients to connect to those servers. SEB doesn’t use any centralized server instances and the according features are by default disabled.
• Fix for «Back to Safari» button/link function in visible Status Bar on iOS 14 before 14.5 in AAC kiosk mode.
• SEB doesn’t show context menu on phone numbers detected by the web view anymore.

• The single app kiosk mode used by SEB is built into the iOS operating system and therefore provides a high level of security.
• Students cannot switch to other apps, access other websites or communicate with other students during an exam.
• Notifications, FaceTime/voice calls and screen shots are also blocked.
• SEB for iOS works both on unmanaged iOS devices like students’ own iPads as well as on iOS devices owned and managed by an institution.В
• SEB for iOS is compatible with the existing versions for macOS and Windows. You can use the same SEB config links and files to start exams in SEB from Safari or Mail or to configure SEB to display your institution’s exam system start/portal page.
• In SEB for iOS exams with individual settings can also be started by QR codes.
• SEB for iOS can be installed and configured using a mobile device management system, as it supports the iOS feature «MDM Managed Configuration».
• SEB for iOS is also compatible with Apple Classroom.
• This version contains some new features currently unique to the iOS version and almost all features of the macOS/Windows versions. Please check theВ compatibility of SEB for iOS version 2.1.14В with your exam system.

See release notes for complete list of new features and changes. Check out the SEB for iOSВ manualВ which explains all features (currently being updated for SEB 3.0). In addition, we published a first version of aВ tutorialВ which will help exam administrators to better understand how to configure and use SEB for iOS. It also includes how SEB for iOSВ can be used together with the Apple Classroom app. More topics will be added to this tutorial over time.
