5.3 Ensure 'Set disk cache size, in bytes' is set to 'Enabled: 250609664'

Information

This setting controls the size of the cache, in bytes, used to store files on the disk.

The recommended state for this setting is: Enabled: 250609664 or greater

NOTE The value specified in this setting isn't a hard boundary but rather a suggestion to the caching system; any value below a few megabytes is too small and will be rounded up to a reasonable minimum.

Rationale:

Having enough disk space for browser cache is important for a computer investigation and for investigators such as Computer Forensics Analysts to be able to retrieve pertinent information to the investigation.

Impact:

Browser cache will take up to 250MB in disk space.

Solution

To establish the recommended configuration via Group Policy, set the following UI path to Enabled: 250609664:

Computer Configuration\Policies\Administrative Templates\Google\Google Chrome\Set disk cache size in bytes

Default Value:

Unset (Same as Enabled with a system managed smaller default size, but the user can change)
