id: "SC-35" title: "External Malicious Code Identification" family: "SC" family_name: "System and Communications Protection" sort_id: "sc-35" priority: "P1" implementation_level: "system"
Statement
Include system components that proactively seek to identify network-based malicious code or malicious websites.
Guidance
External malicious code identification differs from decoys in SC-26 in that the components actively probe networks, including the Internet, in search of malicious code contained on external websites. Like decoys, the use of external malicious code identification techniques requires some supporting isolation measures to ensure that any malicious code discovered during the search and subsequently executed does not infect organizational systems. Virtualization is a common technique for achieving such isolation.
Assessment Objective
system components that proactively seek to identify network-based malicious code or malicious websites are included.
System and communications protection policy
procedures addressing external malicious code identification
system design documentation
system configuration settings and associated documentation
system components deployed to identify malicious websites and/or web-based malicious code
system audit records
system security plan
other relevant documents or records
System/network administrators
organizational personnel with information security responsibilities
organizational personnel installing, configuring, and/or maintaining the system
system developers/integrators
