SV-46909r2_rule DTBC-0005 CCI-001588 HIGH Extensions must be blacklisted by default Extensions are developed by third party sources. They are designed to extend Google Chrome's functionality. An extension can be made by anyone, to do and access almost anything on a system; this means they pose a high risk to any system that would allow all extensions to be installed by default. "Allows you to specify which extensions the users can NOT install. Extensions already installed will be removed if blacklisted.

SV-46910r2_rule DTBC-0006 CCI-001588 MEDIUM Extensions that are approved for use must be whitelisted The whitelist should only contain organizationally approved extensions. This is to prevent users from accidently whitelisitng a malicious extension. "Allows you to specify which extensions are not subject to the blacklist. A blacklist value of * means all extensions are blacklisted and users can only install extensions listed in the whitelist. By default, no extensions are whitelisted. If all extensions have been blacklisted by policy, then the whitelist policy can be used to allow specific extensions to be installed. Administrators should determine which extensions should be allowed to be installed by their users. If no extensions are whitelisted, then no extensions can be installed when combined with blacklisting all extensions" - Google Chrome Administrators Policy ListSystem AdministratorECSC-1
SV-46911r2_rule DTBC-0007 CCI-001588 MEDIUM The default search providers name must be set "Specifies the name of the default search provider.

If you disable this setting, no search is performed when the user enters non-URL text in the omnibox.

If this policy is left unset, background mode is initially disabled and can be controlled by the user in the browser settings." - Google Chrome Administrators Policy List This setting, if enabled, allows Google Chrome to run at all times. There is two reasons that this is not wanted. First, it can tie up system resources that might otherwise be needed. Second, it does not make it obvious to the user that it is running and poorly written extensions could cause instability on the system.System AdministratorECSC-1

Specifically, web pages can not access the WebGL API and plugins can not use the Pepper 3D API. Disabling this setting or leaving it not set potentially allows web pages to use the WebGL API and plugins to use the Pepper 3D API. The default settings of the browser may still require command line arguments to be passed in order to use these APIs." - Google Chrome Administrators Policy List Chrome uses WebGL to render graphics using the GPU. There are few sites that currently take advantage of this feature. Since there is unlikely to be an operational impact, it is recommended that this feature is turned off in order to reduce the attack surface.System Administrator
