Securing VPS

I don't have any 3rdparty processes running on the server, but I wanted to know if anyone here is an expert on server securing and might have some tweaks or tips to make it even more secure.
Hey dynamc,
I find one of the essentials is just ensuring you only run what is required. Once you have the essential services running learn all you can about them. Once you have learned about the services you are running you will have no trouble minimizing security risks.
