5.3.4.3 Intrusion Detection
Check Enable if you wish to detect intruders accessing your computer without permission.
The router automatically detects and blocks a DoS (Denial of Service) attack if a user
enables this function. This kind of attack is not to access confidential data on the network;
instead, it aims to disrupt specific equipment or the entire network. If this happens, users
will have trouble accessing the network resources.
Intrusion Detection: Check Enable if you wish to detect intruders accessing your
computer without permission.
Maximum TCP Open Handshaking Count: This is a threshold value to decide whether
a SYN Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds.
Maximum Ping Count: This is a threshold value to decide whether an ICMP Echo
Storm is occurring or not. Default value is 15 ICMP Echo Requests (PING) per second.
Maximum ICMP Count: This is a threshold to decide whether an ICMP flood is
occurring or not. Default value is 100 ICMP packets per seconds except ICMP Echo
Requests (PING).
Log: Check Log if you wish to generate logs when the filer rule is applied to the Intrusion
Detection.
For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event
Log but it will not be able to protect against such attacks.
