Defeat the Network Attack by using Active Networks approach

The revolution of Internet brings new security risk like attacks against networks. Distributed denial of service shows such feature clearly. Existing attack defense approaches, such as intrusion detection systems, are passive in response against various network attacks; because current attacks are decentralized, automated and intelligent. Some drawbacks of existing systems reveal the necessity of designing a new generation of systems adapted to dynamical environment. Classical security solutions can not easily deal with these necessities. Active networks approach provides interesting characteristics; it is a novel approach that gives networks and services flexibility and spontaneity. With an active network in place, we can build a more active and dynamic attack response by pushing the response actions nearby the attacker, where they can produce better results
