Pamela is Cyber Security Engineer working for Global Instance Firm with large scale deployment of Check Point Enterprise Appliances using GAiA/R81.20. Company's Developer Team is having random access issue to newly deployed Application Server in DMZ's Application Server Farm Tier and blames DMZ Security Gateway as root cause. The ticket has been created and issue is at Pamela's desk for an investigation. Pamela decides to use Check Point's Packet Analyzer Tool-fw monitor to iron out the issue during approved Maintenance window.

What do you recommend as the best suggestion for Pamela to make sure she successfully captures entire traffic in context of Firewall and problematic traffic?

A.
Pamela should check SecureXL status on DMZ Security gateway and if it's turned ON. She should turn OFF SecureXL before using fw monitor to avoid misleading traffic captures.

Suggested answer: A

Explanation:

The best suggestion for Pamela to make sure she successfully captures entire traffic in context of Firewall and problematic traffic is: Pamela should check SecureXL status on DMZ Security gateway and if it's turned ON. She should turn OFF SecureXL before using fw monitor to avoid misleading traffic captures. SecureXL is a technology that accelerates network traffic processing by offloading intensive operations from the Firewall kernel to a dedicated SecureXL device. However, this also means that some traffic might not be seen by fw monitor, which is a tool that captures packets at different inspection points in the Firewall kernel. Therefore, to ensure that fw monitor captures all traffic, SecureXL should be turned OFF before using fw monitor. The other suggestions are either incorrect or less effective in capturing traffic.
