Intrusion Detection Systems (IDS) have been used widely to detect malicious behaviors in network communication and hosts. It is defined as a computer network system to collect information on a number of key points, and analyze this information to see whether there are violations of network security policy behavior and signs of attack. IDS aroused the concern of users as an important computer network security technology. In recent times, with the advent of Cloud Computing, the concepts of Software as a Service (SaaS), where vendors provide key software products as services over the internet that can be accessed by users to perform complex tasks, have become increasingly popular.
