Description

Log Example'

hostname mod_evasive[12345]: Blacklisting address 1.2.3.4: possible DoS attack.

This rule detects when the thresholds you have configured for the mod_evasive module are triggered. mod_evasive is a Denial Of Service detection module for apache, it detects when an IP address exceeds a connection threshold (Example: X connections in Y seconds, or X accesses for the same page from a single IP in Y seconds).

These thresholds are configurable through ASL.

Troubleshooting

False Positives

This rule can be falsely triggered if the configured thresholds for the system have been exceeded.

If you believe that the thresholds are too low for your system, please see the Solutions section below.

Solutions

Please see the Mod_evasive wiki page for detailed guidance.

Solution 1: Increase the thresholds for mod_evasive to be less sensitive

Solution 2: Whitelist the IP

Solution 3: Disable mod_evasive
