Train: Now, this might seem obvious, but you must train your IT staff or others who will access the network. Remember, with one false move, a worker can cause a lot of irreversible damage to your systems.
Updates: Without a doubt, if you do not update your server and add patches, you will see problems in the future. Every year, thousands of computers and servers are infected by a virus because the user does not make simple updates. Luckily, whether you have a Windows or Linux server, you should not have problems making simple updates. When doing so, you will go a long way in protecting your computer and preventing issues.
Minimize software: While it is fun to use a lot of software, you should keep a minimal approach. Remember, when you have too many programs, you will have to deal with plenty of issues. Since one backdoor hacking incident can knock your server offline, you should only use software you truly need.
With these six tips, you can run your server and not worry about serious issues. Simply put, when you can protect your system against hackers and mischievous individuals, you will go a long way in saving time and money as one incident will cause serious issues.
