Description
Unauthorized or unapproved network services lack organizational verification or validation and therefore may be unreliable or serve as malicious rogues for valid services. Examples of network services include service-oriented architectures (SOAs), cloud-based services (e.g., infrastructure as a service, platform as a service, or software as a service), cross-domain, Voice Over Internet Protocol, Instant Messaging, auto-execute, and file sharing.

Check Text (C-205014r831390_chk)

If the ALG does not perform content filtering as part of the traffic management functions, this is not applicable. Verify the ALG generates a log record when unauthorized network services are detected. If the ALG does not generate a log record when unauthorized network services are detected, this is a finding.

Fix Text (F-5282r396416_fix)

If the ALG performs content filtering as part of the traffic management functionality, configure the ALG to generate a log record when unauthorized network services are detected.
