4.9 Firewall
Stateful packet inspection (SPI) 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. These firewalls generally provide the best speed and transparency;
however, they may lack the granular application level access control or caching that some
proxies support.

The P-336M firewall is a stateful inspection firewall and is designed to protect against Denial
of Service attacks when activated. The P-336M’s purpose is to allow a private Local Area
Network (LAN) to be securely connected to the Internet. The P-336M can be used to prevent
theft, destruction and modification of data, as well as log events, which may be important to
the security of your network. The P-336M also has packet-filtering capabilities.

4.9.1 DMZ
The DeMilitarized Zone (DMZ) provides a way for public servers (Web, e-mail, FTP, etc.) to
be visible to the outside world (while still being protected from DoS (Denial of Service)
attacks such as SYN flooding and Ping of Death). These public servers can also still be
accessed from the secure LAN.
