Static packet filtering firewalls always examine application messages in depth.

• A. True
• B. False
• C. Sometimes
• D. Depends on configuration

Answer: (B)

Static packet filtering operates at the network/transport layer and only checks packet headers—things like source and destination IPs, ports, and protocol. It does not inspect the actual application data inside the packet. To examine application messages in depth, you’d need techniques like deep packet inspection or an application-layer firewall. So the statement is not correct: static packet filtering does not routinely examine the payload, it focuses on header information.
