Description

Fail2ban is an open source application that helps protect servers and other services from malicious attacks and malicious activity. It works by monitoring log files (such as SSH logs) for suspicious activity and then taking action to block the IP address of the malicious user or server. By blocking IPs at the firewall level, it prevents the malicious user from accessing the service or website. It does this by using a pattern-matching algorithm to detect malicious activity and then blocking the IP address that is associated with that activity. Fail2ban can also be configured to send out email alerts when malicious activity is detected and blocked.
