Playing with fire(walls), Question No. 4

4.) What advanced firewall architecture examines both incoming and outgoing packets down to the application layer?
A. fail-safe
B. static-packet filtering
C. series circuit
D. stateful inspection

Answer from the SearchSecurity.com glossary:
"Stateful inspection provides enhanced security by keeping track of communications packets over a period of time. Both incoming and outgoing packets are examined. Outgoing packets that request specific types of incoming packets are tracked; only those incoming packets constituting a proper response are allowed through the firewall. In contrast to static packet filtering, in which only the headers of packets are checked, stateful inspection analyzes packets down to the Application layer."
