What does Tap Mode allow you to do regarding firewall rules?

Tap Mode in Trend Micro Deep Security allows for the observation of firewall rules without altering live data streams. This mode is particularly useful for monitoring network traffic and understanding how the firewall rules would behave in a live environment without actually applying any of those rules or making changes to the data being processed.

When operating in Tap Mode, administrators can analyze traffic patterns and assess the effectiveness of the existing firewall configurations without the risk of impacting the network performance or disrupting services. This means that while you can view and analyze the security posture against attacks and traffic anomalies, the actual enforcement of those rules does not take place, preserving the integrity of the live traffic.

The other options involve direct enforcement of rules or implementing security measures, which does not align with the purpose of Tap Mode. Therefore, the choice to observe rules while keeping live streams unaltered is accurate and reflects the functionalities that Tap Mode provides within the system.
