ServerShield - Open Source Linux Hardening Tool

Server Shield:
            is a lightweight method of protecting and hardening your Linux server. It is easy to install, hard to mess up, and makes your server instantly and effortlessly resistant to many basic and advanced attacks

Automatic security updates are enabled by default, including the self-updating of Server Shield. If you are running a modified version of Server Shield you should turn self-updating off so your changes don't get overwritten. Support for servers with multiple IP addresses will be added soon.
