Intrusion Detection System (IDS)
The security feature in the IPLink Router provides protection from a number of attacks. Some attacks cause a
host to be blacklisted (i.e., no traffic from that host is accepted under any circumstances) for a period of time.
Other attacks are simply logged. The subsequent table is a summary of the attacks detected.
1.
To enable IDS, click on Enabled for “Intrusion Detection Enabled” on the “Security Interface Configura-
tion” page. Then click on
Change State
.
2.
Click on
Configure Intrusion Detection...
3.
You may choose which of the parameters to configure and for which value.
– Use Blacklist: Default = 10 minutes when enabled.
If IDS has detected an intrusion an external host, access to the network is denied for ten minutes.
– Use Victim Protection: Default = Disabled.
Victim Protection. When enabled, Victim Protection protects the victim from an attempted spoofing attack.
Web spoofing allows an attacker to create a ‘shadow’ copy of the world wide web (WWW). All access to the
shadow Web goes through the attacker’s machine, so the attacker can monitor all of the victim’s activities and
send false data to or from the victim’s machine. When enabled, packets destined for the victim host of a spook-
ing style attack are blocked.
– Victim Protection Block Duration: Default = 600 seconds
– DOS Attack Block Duration:Default = 1800 seconds (30 minutes).
A Denial of Service (DOS) attack is an attempt by an attacker to prevent legitimate users from using a service.
If a DOS attack is detected, all suspicious hosts are blocked by the firewall for a set time limit
– Scan Attack Block Duration:Default = 86400 seconds
Sets the duration for blocking all suspicious hosts. The firewall detects when the system is being scanned by a
suspicious host attempting to identify any open ports.
