 The best ways to manage Linux servers.
+==Security==
+===SSH===
+The best practice is to not expose SSH.
+Make SSH listen only on local connections and access it through a VPN.
+If you must expose SSH, use a strong SSH key and disable password login.
+===Firewall===
+If your server is behind a NAT (router), a firewall isn't as important.
+For directly connected servers like VPS, you can use [[Uncomplicated Firewall]].
+===Services===
+All your services such as databases should only listen on localhost.
+To access them, you can either find a web interface or use SSH which has port forwarding.
+For services with default root accounts, disable the root account or add a strong password.
