An Implementation of DNS Registration System with Concentrated Management in University for Network Security

Abstract

The DNS servers which exist scatteringly in a university are managed by administrators of each section. Recently the patch works for the DNS servers are needed frequently because the security holes are found many times. Those works are bothering the administrators. It is considered that the concentrated management from those many DNS servers to one makes the total loads of administrators reduced and makes the network security enhanced. In that case, in order to reduce the administrator's load of the concentrated system, it is desired that administrators of each section perform the DNS registration of the individual section. Thus, We have developed the system that each administrator can perform the DNS registration to the concentrated DNS server using each Web brauzer respectively. And all machines, which are assigned to IP address without DNS registration, can be registered simultaneously. Users can request the assignment of IP address from each Web brauzer. Moreover, because all machine's information are registered in the database, the network administration section like an information processing center can manage the total information of all machines in the university. It leads to enhance the network security. This paper introduces the developed system and shows the evaluation.
