SI-4(22): System Monitoring | Unauthorized Network Services

Control Text:

(a) Detect network services that have not been authorized or approved by [Assignment: organization-defined authorization or approval processes]; and (b) [Selection (one or more): Audit; Alert [Assignment: organization-defined personnel or roles]] when detected.

Unauthorized or unapproved network services include services in service-oriented architectures that lack organizational verification or validation and may therefore be unreliable or serve as malicious rogues for valid services.
