Safe Exam Browser

CONCEPT

Safe Exam Browser (SEB) is a web browser environment used to safely carry out e-assessments. It turns any computer into a temporary, 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 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.

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 disabledx.

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.
