Master Assessment Datasheet

Implementation Guidance

The organization being inspected/assessed configures malicious code protection mechanisms to perform periodic scans of the information system on every 7 days. For information system components that have applicable STIGs or SRGs, the organization being inspected/assessed must comply with the STIG/SRG guidance that pertains to CCI 1241. DoD has defined the frequency as every 7 days.

Validation Procedures

The organization conducting the inspection/assessment examines the information system to ensure the organization being inspected/assessed configures malicious code protection mechanisms to perform periodic scans of the information system on every 7 days. For information system components that have applicable STIGs or SRGs, the organization conducting the inspection/assessment evaluates the components to ensure that the organization being inspected/assessed has configured the information system in compliance with the applicable STIGs and SRGs pertaining to CCI 1241. DoD has defined the frequency as every 7 days.

Compelling Evidence

1.) Signed and dated system security plan with section that pertains to frequency with which scans for malicious code are performed (7 days is DoD recommendation). 2.) Protection software logs (logs must contain accurate date/time stamps). 3.) Applicable STIG/SRG checks pertaining to CCI 1241.
