Remote connections should never be allowed that bypass the firewall, as there is no way to verify if they can be trusted. Enables usage of STUN and relay servers when remote clients are trying to establish a connection to this machine. If this setting is enabled, then remote clients can discover and connect to this machine even if they are separated by a firewall. If this setting is disabled and outgoing UDP connections are filtered by the firewall, then this machine will only allow connections from client machines within the local network. If this policy is left not set the setting will be enabled.

Chrome allows you to manage whether unwanted pop-up windows appear. Pop-up windows that are opened when the end user clicks a link are not blocked. If you enable this policy setting, most unwanted pop-up windows are prevented from appearing. If you disable this policy setting, pop-up windows are not prevented from appearing. If you disable this policy setting, scripts can continue to create pop-up windows, and pop-ups that hide other windows. Recommend configuring this setting to ‘2’ to help prevent malicious websites from controlling the pop-up windows or fooling users into clicking on the wrong window. If you do not configure this policy setting, most unwanted pop-up windows are prevented from appearing.

Website tracking is the practice of gathering information as to which websites were accesses by a browser. The common method of doing this is to have a website create a tracking cookie on the browser. If the information of what sites are being accessed is made available to unauthorized persons, this violates confidentiality requirements, and over time poses a significant OPSEC issue. This policy setting allows you to set whether websites are allowed to track the user’s physical location. Tracking the user’s physical location can be allowed by default, denied by default or the user can be asked every time a website requests the physical location. 1 = Allow sites to track the user’s physical location 2 = Do not allow any site to track the user’s physical location 3 = Ask whenever a site wants to track the user’s physical location

Extensions are developed by third party sources and 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. A blacklist value of '*' means all extensions are blacklisted unless they are explicitly listed in the whitelist. If this policy is left not set the user can install any extension in Google Chrome.

The whitelist should only contain organizationally approved extensions. This is to prevent a user from accidently whitelisitng a malicious extension. This policy 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.

Disable support for 3D graphics APIs. Enabling this setting prevents web pages from accessing the graphics processing unit (GPU). Specifically, web pages cannot access the WebGL API and plugins cannot 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. 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.

Each access to a URL is handled by the browser according to the URL's "scheme". The "scheme" of a URL is the section before the ":". The term "protocol" is often mistakenly used for a "scheme". The difference is that the scheme is how the browser handles a URL and the protocol is how the browser communicates with a service. If a scheme or its associated protocol used by a browser is insecure or obsolete, vulnerabilities can be exploited resulting in exposed data or unrestricted access to the browser's system. The browser must be configured to disable the use of insecure and obsolete schemas (protocols). This policy disables the listed protocol schemes in Google Chrome, URLs using a scheme from this list will not load and cannot be navigated to. If this policy is left not set or the list is empty all schemes will be accessible in Google Chrome.
