Daemon Shield is a Linux intrusion prevention daemon that scans for brute force break-in attacks in real time and uses iptables to create rules that block the attackers' IP addresses for a configurable period of time. It is highly configurable through a central configuration file. It loads existing blocklist rules into iptables on startup, and removes the blocklist rules when it shuts down. Other major features include background daemon operation, logging to syslog, easy-to-extend handlers, configurable block duration, and email notifications.... read more
