Strengthening Highlights and Preventing Student Loopholes Follow

The Google Chrome landscape is constantly changing. This page summarizes recent changes to the Highlights installation guide that can be used to strengthen your existing Highlights installation:

 

 

Block Apps or Extensions

Some Apps and Extensions can be used to stop Highlights and other extensions from working correctly. Such Apps and Extensions need to be blocked. Hapara strongly recommends blocking the following extensions:

The instructions on how to do this are here.
 

 

Prevent Students Using Task Manager to End Processes

Students can use the Chrome Task Manager to end processes - including the Highlights extension. Hapara recommends disabling this ability via:

admin.google.com > Device Management > Chrome Management > User Settings

Search for "Task manager" and set the policy to disable the ending of processes. This policy became available in August 2016 and applies to Chromebook devices running version 52 and above. This policy does not apply to Windows, Mac devices using a Chrome Browser.

Turning on this setting for student domains will increase the robustness of Highlights in the face of student interventions. 

 

Prevent Students Using Developer Tools to End Processes

Students can use the Chrome Developer Tools to inspect, break and end processes - including the Highlights extension. Hapara recommends disabling this ability via:

admin.google.com > Device Management > Chrome Management > User Settings

Search for "Developer tools" and set the policy to "Never allow use of built-in developer tools". 

Turning on this setting for student domains will increase the robustness of Highlights in the face of student interventions.
 

 

Prevent Students Using ChromeVox to access Incognito Mode

A vunerability with ChromeVox allows students to access Incognito Mode even if Incognito mode has been disabled in the Google Admin Console. Hapara recommends blocking this weakness via:

admin.google.com > Device Management > Chrome Management > Device Settings

Search for "Turn off accessibility settings on sign-in screen upon logout" and enable this setting.

Enabling this setting for student domains will increase the robustness of Highlights in the face of student interventions.

 

Prevent Students logging out of their School Google Account

Some schools have found it useful to to blacklist these URLs through the Google Admin Console, to prevent students logging out of School Google accounts through Gmail in particular:

If you'd like to keep students from logging out via other apps in Google Suite, then blacklisting this URL should help:https://accounts.google.com/Logout
