11.2.3 Stateful Inspection Firewalls
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. 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. See section 11.5 for more information on
Stateful Inspection.
Firewalls, of one type or another, have become an integral part of standard security solutions for
enterprises.
11.3 Introduction to ParkerVision’s Firewall
The 1500WR Wireless Router firewall is a stateful inspection firewall and is designed to protect against
Denial of Service attacks when activated (in SMT menu 21.2 or in the web Web Configuration Utility).
The 1500WR Wireless Router’s purpose is to allow a private Local Area Network (LAN) to be securely
connected to the Internet. The 1500WR Wireless Router 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
1500WR Wireless Router also has packet-filtering capabilities.
11.4 Denial of Service
Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet.
Their goal is not to steal information, but to disable a device or network so users no longer have access
to network resources. The 1500WR Wireless Router is pre-configured to automatically detect and
thwart all known DoS attacks.
