Stateful Inspection

Stateful Inspection, also known as dynamic packet filtering, is a firewall capability that provides enhanced security by keeping track of the state of active network connections. Unlike traditional packet filtering, which examines each packet independently, stateful inspection monitors the state and context of network traffic, ensuring a higher level of security.

Key aspects of stateful inspection include:

In summary, stateful inspection, or dynamic packet filtering, is a sophisticated firewall technology that enhances network security by monitoring the state of active connections and applying dynamic rules to allow only legitimate traffic. By keeping track of connection states and rejecting unauthorized packets, stateful inspection provides robust protection against a wide range of network threats.
