Research on Design and Security Strategy of DNS

Abstract:

DNS service plays a very important role in the Internet; each host must pass it to query the IP address of the destination host, and can communicate with each other. DNS uses a distributed database structure and server/client mode, which is stored domain name in the server and allowed a client to access the required data. DNS can resolve the host name to the corresponding IP address, while it also can resolve IP address to a host name. With the development of information technology, the network attacks become more and more frequent occurrence in the Internet. So DNS system has suffered a series of attacks frequently, and the communication is severely affected in the Internet. Therefore, the security problems of DNS are increasingly concerned about. The paper describes the composition, features and working principle of DNS system. According to the security risks of the system, it proposes the corresponding security strategy and designs a reliable and safe DNS.
