Monitoring Network Health

ADS

The firewall provides an advanced Attack Detection System (ADS) that may be used to detect and identify various types of attacks initiated on the Wide Area Network (WAN). The system has the capability to detect such attacks the moment they start and to protect the Local Area Network (LAN) from such attacks.

If the Attack Detection System is enabled, the SpeedStream Router provides protection against the most common hacker attacks that attempt to access your computer/network from the Internet. Intrusion attempts can also be logged to provide a record of attempts and their source (when available).

To enable and configure the attack detection feature:

1.Select Setup>Firewall>ADS from the left navigation pane of the Web interface. This displays the “Firewall Attack Detection System” window.

2.Select Enable Attack Detection.

3.Select the Filter checkbox for each event in the list you want to filter or, if you want to filter all events, select the Filter All checkbox. This provides maximum protection against malicious intrusion from outside your network.

4.Select the Log checkbox for each event in the list you want to log or, if you want to log all events, select the Log All checkbox. When logging is selected for a particular offending packet, the ADS will write an entry to the firewall log once a minute for as long as the attack persists. This shows that a long-term attack is taking place without completely filling up the firewall log with entries for every single packet.

5.Click Apply.

Below is a description of each event that can be monitored.

•Same Source and Destination Address

An outside device can send a SYN (synchronize) packet to a host with the same source and destination address (including port) causing the system to hang. When the receiving host tries to respond to the source address in the packet, it ends up just sending it back to itself. This packet could ping-pong back and forth over 200 times (consuming CPU resources) before being discarded.

•Broadcast Source Address

An outside device can send a ping to your Router broadcast address using a forged source address. When your system responds to these pings, it is brought down by echo replies.
