Question 40

What are the differences between using a service versus using an application for Security Policy match?

    Correct Answer: C

    Using a service in a firewall allows the system to take immediate action based on the port numbers observed in the first packet. Applications, on the other hand, can only be identified after observing enough packets to match the application's signature (App-ID), regardless of the ports being used. This distinction is crucial because services are tied to specific ports, whereas applications can be identified by their behavior and characteristics, irrespective of the port.
