Two firewall technologies are prevalent today: the stateful firewall, which provides rudimentary access control based on packet header information, and the application layer firewall, which through deep packet inspection (DPI) and directory service integration enables identity-based access control and security functionality such as intrusion prevention and anti-malware.
