LogReactor Description

Free and open source Python application that watches your system log files, looking for hack attempts This is a fairly simple script, designed to instantly react to hacking attempts, to prevent hackers from gaining entry. If you ever looked at your system logs, and found out too late that someone had been trying to hack in, then this script could help you. It is written in Python, and should operate on all Unix platforms.It works by reading log files that you specify, looking for certain keywords that you specify, that would indicate someone trying to gain illegal access to your computer. For instance, if you see "GET /scripts/.../winnt/system32/cmd.exe?/c+dir HTTP/1.0" in your webserver log, you know someone is up to no good. This program can instantly turn on a firewall rule to block their IP address, or take any other action you wish.It uses full regular expressions, and is multi-threaded.It also has a "warning" feature to prevent false alarms. You can specify that it takes 3 failed login attempts within 10 minutes before the script employs countermeasures. This will prevent legitimate users from locking themselves out.NOTE: LogReactor is licensed and distributed under the terms of the Open Software License 3.0 (OSL3.0).
