Packet filtering firewalls examine the header information of each packet and make filtering decisions based on that information alone. They can allow or deny traffic based on the packet's source and destination IP addresses, ports, and other header information. While not as sophisticated as other types of firewalls, packet filtering is commonly used because it is simple, fast, and less expensive compared to other firewall technologies.
