ConfDroid Puppet Modules - Fail2ban

Introducing confdroid_fail2ban: Automated Brute-Force Protection for Your Puppet-Managed Servers Brute-force attacks remain one of the most common threats to internet-facing services. Attackers continuously scan for open ports and try thousands of username/password combinations against SSH, web logins, admin panels, and other services.
