When Fail2ban detects a suspicious activity, it can either block the IP address temporarily or permanently depending on the settings configured by the system administrator.
What is Nginx?
Nginx is a high-performance, open-source web server software used by many popular websites worldwide, including Netflix, Facebook, and GitHub.
