Firewall

Shorewall

Shorewall (a high-level iptables configuration tool) is used as the basic firewall to protect nanuna in addition to any firewall(s) already protecting UAF's systems.

Fail2ban

Fail2ban is a tool that we use to configure dynamic changes to iptables that will for example block users after too many ssh, apache, or ftp authentication failures.

Apache 2.x
