Answer

Brief Explanations:

A computer firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

  1. They check incoming packets to make sure that they have the right credentials: Firewalls inspect packet headers (IP addresses, ports, and protocols) to verify if the traffic is authorized.
  2. They check the behaviors of packets: Modern firewalls (like stateful inspection or next-generation firewalls) analyze the context and behavior of traffic to detect anomalies or malicious patterns.
  3. They watch packets: This is a general description of packet filtering, where the firewall monitors data units as they move across the network boundary. The statement "They do not allow anything into networks" is incorrect because firewalls are designed to permit legitimate traffic while blocking unauthorized access.

Answer:

  • They check incoming packets to make sure that they have the right credentials.
  • They check the behaviors of packets.
  • They watch packets.
