A MODIFIED NICE MECHANISM WITH DISTRIBUTED HOST-BASED IDS (D-HIDS) SYSTEM

In the past few years Cloud security is a challenging issue that has attracted a lot of research and development effort. Particularly, attackers can explore vulnerabilities and compromise virtual machines to deploy further large-scale Distributed Denial-of-Service (DDoS).Within the cloud system, the detection of zombie exploration attacks is extremely difficult. This is because cloud users may install vulnerable applications on their virtual machines. The existing NICE Method can detect and measure the vulnerabilities, and can counter measure the attacks, but the scalability is very less and there is huge performance degradation in intrusion detections at the Host. To overcome the above problems A Modified NICE Mechanism with a Distributed Host-Based Ids (D-Hids) System is proposed. This D-HIDS enhance the overall accuracy of intrusion assessment as well as the ability of detecting new classes of intrusions. In addition to that, this A new decentralized access control scheme is introduced to make our design still stronger to access in a decentralized manner.
