CCI-002672

Analyze outbound communications traffic at organization-defined interior points within the system to detect covert exfiltration of information.

Implementation Guidance

Determine if: - outbound communications traffic is analyzed at interfaces external to the system to detect covert exfiltration of information. - outbound communications traffic is analyzed at [SI-04(18)_ODP; interior points within the system where communications traffic is to be analyzed are defined] to detect covert exfiltration of information.

Validation Procedures

Examine: [SELECT FROM: System and information integrity policy; system and information integrity procedures; procedures addressing system monitoring tools and techniques; system design documentation; network diagram; system monitoring tools and techniques documentation; system configuration settings and associated documentation; system monitoring logs or records; 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 monitoring the system; organizational personnel responsible for the intrusion detection system]. Test: [SELECT FROM: Organizational processes for intrusion detection and system monitoring; mechanisms supporting and/or implementing intrusion detection and system monitoring capabilities; mechanisms supporting and/or implementing an analysis of outbound communications traffic].
