The Palo Alto Networks security platform must enable Antivirus, Anti-spyware, and Vulnerability Protection for all authorized traffic.

Description
The flow of all communications traffic must be monitored and controlled so it does not introduce any unacceptable risk to the network infrastructure or data. Restricting the flow of communications traffic, also known as Information flow control, regulates where information is allowed to travel as opposed to who is allowed to access the information and without explicit regard to subsequent accesses to that information. Traffic that is prohibited by the PPSM and Vulnerability Assessments must be denied by the policies configured in the Palo Alto Networks security platform; this is addressed in a separate requirement. Traffic that is allowed by the PPSM and Vulnerability Assessments must still be inspected by the IDPS capabilities of the Palo Alto Networks security platform known as Content-ID. Content-ID is enabled on a per rule basis using individual or group profiles to facilitate policy-based control over content traversing the network.

Review the list of authorized applications, endpoints, services, and protocols that has been added to the PPSM database. Identify which traffic flows are authorized. Go to Objects >> Security Profiles >> Antivirus If there are no Antivirus Profiles configured other than the default, this is a finding. Go to Objects >> Security Profiles >> Anti-Spyware View the configured Anti-Spyware Profiles. If none are configured, this is a finding. Go to Objects >> Security Profiles >> Vulnerability Protection View the configured Vulnerability Protection Profiles. If none are configured, this is a finding. Review each of the configured security policies in turn. For any Security Policy that allows traffic between Zones (interzone), view the "Profile" column. If the "Profile" column does not display the Antivirus Profile, Anti-Spyware, and Vulnerability Protection symbols, this is a finding.
