Also referred to as dynamic packet filtering. Stateful inspection is a firewall architecture that works at the network layer. Unlike static packet filtering, which examines a packet based on the information in its header, stateful inspection tracks each connection traversing all interfaces of the firewall and makes sure they are valid.
Term used to describe one particular type of firewall architecture, whereby the firewall intercepts, analyses and takes action on all communications before they enter the operating system of the gateway machine.
Also referred to as dynamic packet filtering. It's a firewall architecture that works at the network layer. Stateful inspection checks both the header information and contents of the packet. As an added security measure against port scanning, stateful inspection firewalls close off ports until connection to the specific port is requested.
A technology developed and patented by Check Point Software Technologies that provides the highest level of security available. Stateful Inspection accesses and analyzes all the data derived from all communication layers.This state and context data is stored and updated dynamically, providing virtual session information for tracking connectionless protocols. Cumulative data from the communication and application states, network configuration and security rules are all used to decide on an appropriate action, either accepting, rejecting or encrypting the communication. Any traffic not explicitly allowed by the security policy is dropped.
firewall technology that monitors the state of the transaction so that it can verify that the destination of an inbound packet matches the source of a previous outbound request.
