Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 441
Information Security is enforcing group-based policies by using security-event monitoring on Windows User-ID agents for IP-to-User mapping in the network. During the rollout, Information Security identified a gap for users authenticating to their VPN and wireless networks.
Root cause analysis showed that users were authenticating via RADIUS and that authentication events were not captured on the domain controllers that were being monitored. Information Security found that authentication events existed on the Identity Management solution (IDM).
There did not appear to be direct integration between PAN-OS and the IDM solution.
How can Information Security extract and learn IP-to-user mapping information from authentication events for VPN and wireless users?
Answer options
- A. Configure the integrated User-ID agent on PAN-OS to accept Syslog messages over TLS.
- B. Configure the User-ID XML API on PAN-OS firewalls to pull the authentication events directly from the IDM solution.
- C. Add domain controllers that might be missing to perform security-event monitoring for VPN and wireless users.
- D. Configure the Windows User-ID agents to monitor the VPN concentrators and wireless controllers for IP-to-User mapping.
Correct answer: A
Explanation
The correct answer is A because configuring the integrated User-ID agent to accept Syslog messages over TLS allows the capture of relevant authentication events. Option B is incorrect as it suggests pulling events directly, which may not be feasible without direct integration. Option C does not address the root issue of missing authentication event capture, and option D does not solve the problem since it focuses on monitoring rather than capturing the necessary events.
