devopera-docsf

ConfigServer Firewall (csf) and Login Failure Daemon (lfd) are designed to protect online servers by providing an adaptive firewall and access/process monitoring service. CSF in turn uses IPtables to actually implement the firewall rules. This module also includes Linux Malware Detect (maldet) for detecting malware.
