Network activity classification schema in IDS and log audit for cloud computing

Cloud computing plays an important role in web .The term cloud computing is based on internet computing. Cloud computing is a service to perform tasks through internet. It provides large scale of resource to each user using virtual machine. Cloud computing is easily threatened by the users because all users are not trustworthy. This is the first problem. The second problem in cloud computing is number of users can use the service but it makes the admin to analyze the log. In this paper ,we propose the multilevel intrusion detection system and log audit for detecting the attacks and maintain the security level and effectiveness of the system. The intrusion detection system is based on data mining techniques and anomaly detection method.
