Master Assessment Datasheet

Implementation Guidance

Determine if: - malicious code protection mechanisms are configured to perform periodic scans of the system [SI-03_ODP[02]; the frequency at which malicious code protection mechanisms perform scans is defined]. - malicious code protection mechanisms are configured to perform real-time scans of files from external sources at [SI-03_ODP[03]; one or more of the following PARAMETER VALUES is/are selected: {endpoint; network entry and exit points}] as the files are downloaded, opened, or executed in accordance with Organizational policy.

Validation Procedures

Examine: [SELECT FROM: System and information integrity policy; system and information integrity procedures; configuration management policy and procedures; procedures addressing malicious code protection; malicious code protection mechanisms; records of malicious code protection updates; system design documentation; system configuration settings and associated documentation; scan results from malicious code protection mechanisms; record of actions initiated by malicious code protection mechanisms in response to malicious code detection; system audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; organizational personnel installing, configuring, and/or maintaining the system; organizational personnel responsible for malicious code protection; organizational personnel with configuration management responsibilities]. Test: [SELECT FROM: Organizational processes for employing, updating, and configuring malicious code protection mechanisms; organizational processes for addressing false positives and resulting potential impacts; mechanisms supporting and/or implementing, employing, updating, and configuring malicious code protection mechanisms; mechanisms supporting and/or implementing malicious code scanning and subsequent actions].
