SV-87929r1_rule The roles and features required by the system must be documented.

Vulnerability discussion

Unnecessary roles and features increase the attack surface of a system. Limiting roles and features of a system to only those necessary reduces this potential. The standard installation option (previously called Server Core) further reduces this when selected at installation.

Check content

Required roles and features will vary based on the function of the individual system. Roles and features specifically required to be disabled per the STIG are identified in separate requirements. If the organization has not documented the roles and features required for the system(s), this is a finding. The PowerShell command "Get-WindowsFeature" will list all roles and features with an "Install State".

Fix text

Document the roles and features required for the system to operate. Uninstall any that are not required.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
