Which of the following types of firewall operates at the Network layer to examine incoming and outgoing packets?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i,e, Packet filtering.

  • The type of firewall that operates at the Network layer to examine incoming and outgoing packets is called a "Network Firewall" or "Packet Filtering Firewall."
  • This type of firewall makes decisions about whether to allow or block traffic based on criteria such as source and destination IP addresses, port numbers, and protocols.
  • It works by inspecting the headers of individual packets as they pass through the firewall and applying predefined rules to determine whether the packets should be allowed to pass through or not.
