Vulnerability discussion

Without verification of the security functions, security functions may not operate correctly and the failure may go unnoticed. Security function is defined as the hardware, software, and/or firmware of the information system responsible for enforcing the system security policy and supporting the isolation of code and data on which the protection is based. Security functionality includes, but is not limited to, establishing system accounts, configuring access authorizations (i.e., permissions, privileges), setting events to be audited, and setting intrusion detection parameters.This requirement applies to operating systems performing security function verification/testing and/or systems and environments that require this functionality.

Check content

Ask the system administrator (SA) if there is a documented procedure for validation of security functions on file with the ISSM/ISSO. If there is none, this is a finding. Ask for evidence that the procedures are performed. If there is no evidentiary proof, this is a finding.

Fix text

Develop a procedure that validates all security functions. Develop a log depicting date and time of validation signed by action official.

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.
