■Packet-Filtering Firewalls
As the most “basic” and oldest type of firewall architecture, packet-filtering firewalls basically create a checkpoint at a traffic router or switch. The firewall performs a simple check of the data packets coming through the router—inspecting information
■Circuit-Level Gateways
As another simplistic firewall type that is meant to quickly and easily approve or deny traffic without consuming significant computing resources, circuit-level gateways work by verifying the transmission control protocol (TCP) handshake
■ Stateful Inspection Firewalls
These firewalls combine both packet inspection technology and TCP handshake verification to create a level of protection greater than either of the previous
■ Proxy Firewalls (Application-Level Gateways)
Proxy firewalls operate at the application layer to filter incoming traffic between your network and the traffic source—hence, the name “application-level gateway.”
