It also works on the basis of a set of rules for filtering packets but operates at the transport layer of the OSI Model so has greater functionality. Application gateway firewall It operates at application layer of the OSI Model. It uses strong user authentication to verify identity of a host attempting to connect to the network using application layer protocols such us FTP. In contrast to packet filter firewall, it filters the requests rather than packets entering/leaving the network. It can block any outgoing HTTP or FTP requests.
