FCSS – Enterprise Firewall Administrator 7.6 — Question 6

To secure your enterprise network traffic, which step does FortiGate perform first, when handling the first packets of a session?

Answer options

• A. Decryption
• B. Installation of the session key in the network processor (NP)
• C. A reverse path forwarding (RPF) check
• D. IP integrity header checking

Correct answer: D

Explanation

The first step that FortiGate performs is the IP integrity header checking, which ensures that the packet headers are intact and have not been tampered with. The other options, like decryption and session key installation, occur later in the process after initial checks. The RPF check is also a subsequent step and not the first action taken.
