Protocol Specific Multi-Threaded Network Intrusion Detection System (PM-NIDS) for DoS/DDoS Attack Detection in Cloud

Cloud computing has added new dimensions to the world of computing technology. However, it has various security and privacy concerns. The major threats are Denial of service (DoS) and Distributed Denial of Service (DDoS) attacks to the cloud technology in recent years. In this paper, we design an efficient security framework which is protocol specific Multithreaded Network Intrusion Detection System (PM-NIDS) aiming at detecting DoS/DDoS attacks in the cloud. Here, the incoming packets are separated according to the protocol and queued for further processing. Each queue is handled by a framework thread which extracts the relevant features and applies protocol specific classifiers for each packet in the queue. Finally, it generates the alerts for the detected intrusions. We have performed different experiments for the feasibility analysis and validation of the proposed framework.
