Abstract:

In the monitoring and the statistics of domain name system （DNS） security, DNS query logs may reduce the DNS performance, and the lagging progress may result in an unusual disposal. In order to solve these problems, a DNS real-time monitoring and statistical system （DRMSS） is designed based on a multi-level framework. DRMSS uses a BSD packet filter （BPF） to filter DNS service message and employs the memory caching mechanism to store and handle the real-time monitoring and statistical information. Experimental results indicate that DRMSS is sui- table for the real-time monitoring and statistical integration of multi-domain name service software, and greatly im- proves the service performance and security of DNS.

Key words: domain name system, packet filtering, real-time monitoring, statistical integration
