Fail2Ban
Daemon to ban hosts that cause multiple authentication errors
Fail2Ban is an open-source intrusion prevention daemon that monitors log files for repeated failed authentication attempts and automatically updates firewall rules to block offending IP addresses. It supports a wide range of standard log formats out of the box, including sshd and Apache, and is highly configurable. The tool runs on Linux systems and is distributed under the GNU General Public License.
Fail2Ban scans log files for repeated authentication failures and dynamically updates firewall rules to temporarily ban the offending IP addresses.
