Try Server Monitoring (Score 1)

No, that's a good question. To save money and maybe even take advantage of more knowledge and experience - you may need to outsource such activities and for THEM to save money, which saves you money, they want to remote access into your system. Others may want to outsource their servers to farm (like a web or email server). This could open up the server to the remote vendors admins. You may not know them and the vendor may not even know them if they new. You can never be to careful - we've all worked with newbees who have crashed us. Spectorsoft (I use their employee monitoring software for investigations but others may know them for their kid monitoring software) has JUST released a new server monitoring software (might be called Spector Server at spectorserver.com). From what I read it records only when an admin logs in and then records everything each one does including screen snap shots (which, along with their keylogger is the best that can be found.)I am looking at it to monitor my Citrix Server but I can see where it might give you peace of mind with vendors, etc.
