Fail2ban
Top / Fail2ban
Fail2ban scans log files (e.g. /var/log/apache/error_log) and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc.
- Generally Fail2Ban then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. sending an email, or ejecting CD-ROM tray) could also be configured.
- Out of the box Fail2Ban comes with filters for various services (Apache, Curier?, SSH, etc).
