Brand Details
Type: Product
Description: Fail2Ban is an intrusion prevention system that enhances server security by automatically blocking malicious IP addresses. It achieves this by monitoring server log files for suspicious activity, such as repeated failed login attempts or other malicious patterns. When it detects a predetermined number of such attempts within a specified time frame, it automatically adds firewall rules to block the offending IP address for a set duration. This process helps mitigate brute-force attacks and other automated threats without manual intervention. Fail2Ban is highly configurable, allowing administrators to customize the sensitivity, duration of bans, and actions taken. It can be used to protect various services, not just SSH, extending its effectiveness across a broader range of applications.
