packet filtering
Last modified: Monday, June 25, 2001 

Also referred to as static packet filtering. Controlling access to a network by analyzing the incoming and outgoing packets and letting them pass or halting them based on the IP addresses of the source and destination. Packet filtering is one technique, among many, for implementing security firewalls.

Compare with stateful inspection.
