A Novel Online Technique to Characterize and Mitigate DoS Attacks using EPSD and Honeypots

摘要: Denial of Service (DoS) attacks pose a severe security threat to the steady functioning any network. These aim at depleting resources server or an administrative network by overwhelming it with enormous and useless traffic. The outcome this is fact that legitimate users are denied service. Though array schemes has been proposed for detection presence these attacks, characterizing flows as normal flow malicious one, identifying sources mitigating effects once they have detected, there still dearth complete frameworks encompass multiple stages process defense against DoS attacks. In paper, we propose novel framework which deals characterization TCP UDP flows, identification source characterized attack influence attack. achieved innovative Exactly Periodic Subspace Decomposition (EPSD) based approach, whereas proactive roaming honeypot scheme deployed mitigation same. We validate effectiveness approach simulation in ns-2 on Linux platform.
