Data Center Management Department Is Isolated

In the office, we have a department in Information Technology that cannot be accessed by anyone not part of the depratment.  It is called Data Center Management.  That is where the data for all the credit card transactions for all users are generated and downloaded.  The system is really sensitive and there was one time when one of the members of that department bought a girfriend over.  The girlfriend without any malicious intention pulled out the plug of one of the servers there.  So the company lost a billion of dollars because of that because all the transactions for that one night was not generated.  That is how important and how sensitive the DCM Department is.
