3.6.3.4.2 INTRUSION DETECTION
 
 
The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts 
from the Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and 
blocked depending on whether they are detected as possible hacker attacks, intrusion attempts or other 
connections that the router determines to be suspicious. 
Blacklist: If the router detects a possible attack, the source IP or destination IP address will be added 
to the Blacklist. Any further attempts using this IP address will be blocked for the time period 
specified as the Block Duration. The default setting for this function is false (disabled). Some attack 
types are denied immediately without using the Blacklist function, such as Land attack and 
Echo/CharGen scan
Block Duration: 
•  DoS Attack Block Duration: This is the duration for blocking hosts that attempt a possible 
Denial of Service (DoS) attack. Possible DoS attacks this attempts to block include Ascend Kill 
and WinNuke. Default value is 1800 seconds.
