1.119 (L1) 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

Note: The value specified in this policy 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.

Note #2: The recommended disk size for cache is 50 - 250MB, according to Microsoft.

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

Solution

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

Computer Configuration\Policies\Administrative Templates\Microsoft Edge\Set disk cache size, in bytes

Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MSEdge.admx/adml that can be downloaded from:

Download Microsoft Edge for Business - Microsoft

.

Impact:

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