Which technology is responsible for extracting detailed information from packets and storing that information in state tables?

The technology responsible for extracting detailed information from packets and storing that information in state tables is the Stateful Inspection mechanism. Stateful Inspection is a fundamental characteristic of modern firewalls that allows them to analyze the state and context of network connections as they traverse a firewall.

This technique maintains a state table, which keeps track of the state of active connections. It not only looks at the header information of packets but also examines the content and context of the traffic to determine whether it is part of an established connection or if it is a new connection attempting to be initiated. By doing so, Stateful Inspection provides a more comprehensive level of security than simple packet filtering, offering better protection by understanding the state of the traffic and protocols being used.

In context, while the INSPECT Engine is part of Check Point's specific architecture and is used within their firewall technology, it is typically the Stateful Inspection that serves the core function of maintaining state tables for active connections. Packet Filtering, on the other hand, does not involve tracking the state of connections but merely makes decisions based on header information, which is less sophisticated. The Application Layer Firewall operates at a higher level, inspecting application data but also relies on stateful inspection for maintaining connection states.

Thus, the emphasis on maintaining state tables and extracting
