That is a very broad subject. Securing your server/s depends upon what you want to use them for. The most secure this to do is inpluf your network connections and put the machine in a locked box! However, from the apps you describe I guess you want some exposure to the outside world! To control the flow of network, you should manage iptables. If you are concerned about security, it is worth learning how to control the firewall using iotabkes. If you want to apply some security quickly then try a firewall GUI first and apply some simple rules to allow/deny traffic.
