Easy if you're a system admin, if not then seek some help as an insecure server will soon become a target for script kiddies to either deface or to use as a spam router.
Once the server is on place, then it's at least daily checks to make sure all's well, regular hard work to keep the box sweet. You can lighten this workload by selling higher quality non-oversold accounts, however if you want the high profits most people seem to think are just laying about ready to get rich on, then you need to work hard
