16. What are the basic types of firewalls Conceptually there are three types of firewalls 1 Packet Filtering Firewall 2 Application level Firewall 3 Stateful Inspection Firewall Packet Filtering Firewalls generally make their decisions based on the header information in individual packets These header information include the source destination addresses and ports of the packets Application level Firewalls generally are hosts running proxy servers which permit no traffic directly between networks and which perform logging and auditing of traffic passing through them A proxy server is an application gateway or circuit level gateway that runs on top of general operating system such as UNIX or Windows NT It hides valuable data by requiring users to communicate with secure systems by mean of a proxy A key drawback of this device is performance Stateful Inspection Firewalls restrict access by screening data packets against defined access rules They make access control decisions based on IP address and protocol They also inspect the session data to assure the integrity of the connection and to adapt to dynamic protocols The flexible nature of Stateful Inspection firewalls generally provides the best speed and transparency however they may lack the granular application level access control or caching that some proxies support What kind of firewall is the Prestige 1 The Prestige s firewall inspects packets contents and IP
