Abstract: Distributed and open structure of Cloud Computing model and its services makes it attractive for potential intruders. Providing security in a distributed system requires more than user authentication with passwords or digital certificates and confidentiality in data transmission. Distributed model of Cloud makes it vulnerable and prone to sophisticated distributed intrusion attacks like Distributed Denial of Service (DDOS). The conventional Intrusion detection and prevention systems are not sufficient to be deployed in Cloud environment because of its openness and service structures. The objective of this project is to analyze or investigate possible solutions to detect and prevent intrusions in Cloud Computing Systems. Based on the survey and experiences with traditional intrusion detection systems, decision tree based models is proposed for IDPS implementation.
