Harold has just been hired on as the senior network administrator for the University of Central Michigan. He essentially is in charge of 200 servers and about 10,000 client computers. Because of the immense network size of the university, Harold wants to centrally manage the network as much as possible.
Harold supervises 10 server administrators, 4 Exchange administrators, and 20 help desk technicians. Because of the separated job duties, Harold wants to ensure that nothing is changed on the network without his knowledge and consent. His main concern is the 200 servers his subordinates take care of.
Harold wants to be alerted whenever critical files, folders, shares, etc are changed on any of the servers, and he wants all this information available to him from one management console, not a console on each individual server. What tool could Harold use to centrally manage any changes on his servers?

A.
SAINT

B.
Nessus

C.
SATAN

D.
Tripwire
