Community aware network security and a DDoS response system

Due to the considerable growth of Internet as well as its usage as a commercial platform, attacks against networks such as Distributed Denial of Service (DDoS) attacks, have emerged, with victims even among prestigious commercial sites. Such attacks in traditional networking are difficult to recognize and to handle. Managing them requires a network that can dynamically detect, share info, respond to event-triggered requests and proactively secure itself. We present here a community aware network security as well as hands on experience with a specific threat i.e. a DDoS scenario and attack response system approach. We demonstrate the dynamicity and flexibility of the community-aware networks in dealing with this kind of threats. The implementation is based on agent-enabled active networks and makes heavy use of the mobile agent technology in order to asynchronously respond to critical situations. Finally we comment on the pros and cons of our approach and discuss future directions that could be followed.
