ConfigServer Security & Firewall (it is also called csf in short) is a Stateful Packet Inspection (SPI) firewall, Login/Intrusion Detection and Security application for Linux servers.
To complement the ConfigServer Firewall (csf), is developed a Login Failure Daemon (lfd) process that runs all the time and periodically (every X seconds) scans the latest log file entries for login attempts against your server that continually fail within a short period of time. Such attempts are often called “Brute-force attacks” and the daemon process responds very quickly to such patterns and blocks offending IP’s quickly.
