It's a vast area to write and manage modern MIS system covering and interfacing and exchanging and information among network and HRIS.
at detail level you may have to refer to some general books written on the subject and extract to abstract the concept to fit into the most of the vide organization.

But it should cover person intraction with the network, prevent unauthorised use of network, network availability, statistics data availability, fault tolerence and locate and fix, HR systems interaction management etc....
