Fix Recommendation

If the BIG-IP Core performs content filtering as part of the traffic management functionality, configure the BIG-IP Core as follows:

Configure a policy in the BIG-IP ASM module to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.

Apply ASM policy to the applicable Virtual Server(s) in BIG-IP LTM module to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.

Check Contents

If the BIG-IP Core does not perform content filtering as part of the traffic management functionality for virtual servers, this is not applicable.

When content filtering is performed as part of the traffic management functionality, verify the BIG-IP Core is configured as follows:

Verify Virtual Server(s) in the BIG-IP LTM module are configured with an ASM policy to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.

Navigate to the BIG-IP System manager >> Local Traffic >> Virtual Servers >> Virtual Servers List tab.

Select Virtual Servers(s) from the list to verify.

Navigate to the Security >> Policies tab.

Verify that "Application Security Policy" is Enabled and "Policy" is set to use an ASM policy to continuously monitor inbound communications traffic crossing internal security boundaries for unusual or unauthorized activities or conditions.

If the BIG-IP Core is not configured to continuously monitor inbound communications traffic for unusual or unauthorized activities or conditions, this is a finding.
