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.
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. To verify if a Security Policy logs denied traffic: Go to Policies >> Security Select the name of the security policy to view it. In the "Actions" tab, in the "Log Setting" section, if neither the "Log at Session Start" nor the "Log at Session End" check boxes are checked, this is a finding.
