Which statement is true regarding packet handling at a firewall after a 3-way handshake?

In the context of packet handling at a firewall after a 3-way handshake, the correct answer reflects the behavior of firewalls when status detection is turned off. When status detection is disabled, the firewall operates under a simplistic packet filtering paradigm. In this case, if there is a permit policy configured, packets can flow through the firewall without additional checks or the establishment of a session table.

This means that the firewall does not maintain state information about connections or track session data, allowing for more simplistic and potentially insecure handling of packets. This can lead to vulnerabilities because every packet is treated independently, and the firewall does not track whether it is part of an established session.

Other options suggest that session tables or specific security policies are always a requirement in this process, which does not align with the behavior of a firewall operating with status detection disabled. Therefore, it highlights the importance of understanding the fundamental differences in how firewalls process packets based on their configuration settings.
