Providing network security on campus networks with open source code software :A sample of Afyon Kocatepe Universty

According to law T.C 5651, public and private institutions acting as internet service provider should keep internet access log records with time-stamps. In this context, the current internet access log records of Afyon Kocatepe University were analyzed. Currently only firewall log records are held on system, but these records don?t meet the requirements of the law. In addition, there are some network security issues and further problems caused by the misconfigured devices running on the campus network. The goal of this study is providing methods to save all users access records, regardless of using wired or wireless network, time-stamped and correctly with the help of open source software. For this purpose, the campus network devices are reconfigured, the captive portal technique is used for the laboratories and locations without managed devices. For other places with only managed devices, the 802.1X protocol is used. In this way, the network connection problems are solved, and internet access log records of all users are kept in the manner prescribed by the law.
