A botnet-oriented collaborative defense scheme description language

Botnets are one of the most serious threats to Internet security. Isolated and single point security defense technologies can't effectively counteract large-scale, distributed botnet attacks, such as Spamming and Distributed Denial of service attack. Collaboration among different kind of security devices is needed. To solve this problem, we proposed a conceptual model of botnet collaborative defense scheme and designed a Botnet Collaborative Defense Scheme Description Language (BCDSDL).Then, we outlined its EBNF expressions. The BCDSDL can uniformly describe the defense tasks and relations among tasks of different kinds of security devices, and provides a language level interface for diverse security devices achieving information sharing and linkage defense. At last, we realized the simulation of collaborative defense schemes described by BCDSDL in GTNetS. The experiment results show that BCDSDL is efficient and easy to use.
