SI-04(04) [H] Inbound and Outbound Communications Traffic
Control
- Determine criteria for unusual or unauthorized activities or conditions for inbound and outbound communications traffic;
- Monitor inbound and outbound communications traffic [Assignement: organization-defined frequency] for [Assignement: organization-defined unusual or unauthorized activities or conditions].
Discussion
Unusual or unauthorized activities or conditions related to system inbound and outbound communications traffic includes internal traffic that indicates the presence of malicious code or unauthorized use of legitimate code or credentials within organizational systems or propagating among system components, signaling to external systems, and the unauthorized exporting of information. Evidence of malicious code or unauthorized use of legitimate code or credentials is used to identify potentially compromised systems or system components.
Assessment Objective
- criteria for unusual or unauthorized activities or conditions for inbound communications traffic are defined;
- criteria for unusual or unauthorized activities or conditions for outbound communications traffic are defined;
- inbound communications traffic is monitored [Assignement: frequency] for [Assignement: unusual or unauthorized activities or conditions];
- outbound communications traffic is monitored [Assignement: frequency] for [Assignement: unusual or unauthorized activities or conditions].
Assessment Method
Examine
System and information integrity policy
system and information integrity procedures
procedures addressing system monitoring tools and techniques
system design documentation
system monitoring tools and techniques documentation
system configuration settings and associated documentation
