A stateful multilayer inspection firewall combines the aspects of Application level gateway, Circuit level gateway and Packet filtering firewall. On which layers of the OSI model, does the Stateful
A stateful multilayer inspection firewall operates across multiple layers of the OSI model, specifically the Network, Session, and Application layers. It combines the features of packet filtering, circuit-level gateway, and application-level gateway firewalls. This type of firewall inspects the state and context of network traffic, ensuring that all packets are part of a known and valid session. It can make decisions based on the connection state as well as the contents of the traffic, providing a thorough inspection across these layers.
References: The information is consistent with the characteristics of stateful multilayer inspection firewalls as described in various sources, which confirm that they work across the Network, Session, and Application layers of the OSI model1234.
