Discussion

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 Content

Obtain the list of network services that have not been authorized or approved by the ISSM and ISSO.
For each prohibited network service, view the security policies that denies traffic associated with it and logs the denied traffic.

If there is no list of unauthorized network services, this is a finding.

If there are no configured security policies that specifically match the list of unauthorized network services, this is a finding.

If the security policies do not deny the traffic associated with the unauthorized network services, this is a finding.
