Fix Recommendation

If user packet-filtering intermediary services are provided, configure the BIG-IP Core as follows:

Configure a policy in the BIG-IP AFM module to restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

Apply the AFM policy to the applicable Virtual Server(s) in the BIG-IP LTM module to restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks.

Check Contents

If the BIG-IP Core does not perform packet-filtering intermediary services for virtual servers, this is not applicable.

When packet-filtering intermediary services are performed, verify the BIG-IP Core is configured as follows:

Verify Virtual Server(s) in the BIG-IP LTM module is configured with an AFM policy to restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

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 "Network Firewall" Enforcement is set to "Policy Rules..." and "Policy" is set to use an AFM policy to restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic.

If the BIG-IP Core is not configured to restrict or block harmful or suspicious communications traffic by controlling the flow of information between interconnected networks based on attribute- and content-based inspection of the source, destination, headers, and/or content of the communications traffic, this is a finding.
