Assessment Objective
Determine if:
- SI-03a.
- SI-03a.[01] [Selection (one or more): signature-based; non-signature-based] malicious code protection mechanisms are implemented at system entry and exit points to detect malicious code;
- SI-03a.[02] [Selection (one or more): signature-based; non-signature-based] malicious code protection mechanisms are implemented at system entry and exit points to eradicate malicious code;
- SI-03b. malicious code protection mechanisms are updated automatically as new releases are available in accordance with organizational configuration management policy and procedures;
- SI-03c.
- SI-03c.01
- SI-03c.01[01] malicious code protection mechanisms are configured to perform periodic scans of the system [Assignment: frequency];
- SI-03c.01[02] malicious code protection mechanisms are configured to perform real-time scans of files from external sources at [Selection (one or more): endpoint; network entry and exit points] as the files are downloaded, opened, or executed in accordance with organizational policy;
- SI-03c.02
- SI-03c.02[01] malicious code protection mechanisms are configured to [Selection (one or more): block malicious code; quarantine malicious code; take [Assignment: action] ] in response to malicious code detection;
- SI-03c.02[02] malicious code protection mechanisms are configured to send alerts to [Assignment: personnel or roles] in response to malicious code detection;
- SI-03c.01
- SI-03d. the receipt of false positives during malicious code detection and eradication and the resulting potential impact on the availability of the system are addressed.
Assessment Methods
Examine
- 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
- 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
- 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
