+SI-04(18) Analyze Traffic and Covert Exfiltration

SI-04(18) Analyze Traffic and Covert Exfiltration

Control

Analyze outbound communications traffic at external interfaces to the system and at the following interior points to detect covert exfiltration of information: [Assignement: interior points].

Discussion

Organization-defined interior points include subnetworks and subsystems. Covert means that can be used to exfiltrate information include steganography.

Assessment Objective

  1. outbound communications traffic is analyzed at interfaces external to the system to detect covert exfiltration of information;
  2. outbound communications traffic is analyzed at [Assignement: interior points] to detect covert exfiltration of information.

Assessment Method

Examine

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
