Packet Filtering
Packet Filtering is a type of Firewall. Packet Filtering Firewalls work at the
network level of the IP layer of TCP/IP. In a packet filtering firewall, each
packet is analyzed to a strict set of criteria before it is allowed to pass.
Depending on the packet and the criteria, the firewall will either drop the
packet, forward it, or send a message back to the original source. Traffic is
filtered based upon these specified rules that may include: examining the
source and destination IP addresses of packets, port numbers, and protocol
used.
