The Intrusion Detection feature of the Barricade limits the access of the incoming traffic from the WAN side. The Stateful Packet Inspection (SPI) functionality is enabled by default. You can also configure the router to discard pings from the WAN side.

When hackers attempt to enter your network, the Barricade can alert you via e- mail. You simply need to enter your email address and the SMTP mail server address. The Wireless Barricade Turbo inspects packets at the application layer and maintains TCP and UDP session information, including timeouts and number of active sessions, thus providing the ability to detect and prevent certain types of network attacks such as DoS attacks.

Network attacks that deny access to a network device are called denial-of-service (DoS) attacks. Denial 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 resource. By using the appropriate inspected information and timeout/threshold criteria, the Wireless Barricade Turbo prevents these types of attacks.
