User Auto-logging and Tracing Technologies in Campus Network

For locating and analyzing the secure incidents of campus network, we need auto-logging and tracing all user's information. By collecting and analyzing the data from user authentification log, DHCP log, switch log and router log, the key technologies on auto-logging and tracing are solved. We design and develop a prototype system and deploy it in our campus network. Simulation results show that our solution is valuable.
