Packet Filtering: A technique where packets of data are analyzed while they are traversing a network interface. Depending on predefined criteria such as IP addresses, protocols, port numbers, or other packet attributes, the packet filter can block or allow packets to pass through. This is commonly used in firewalls and routers as a basic method to control incoming and outgoing network traffic, providing a first line of defense against malicious activities.
