Journal of Information Security Research Bashair Al-Shdaifat, Wafa’ Slaibi Alsharafat, Mohmmad el-bashir 6 1 2015 http://www.dline.info/jisr/fulltext/v6n2/v6n2_2.pdf Recently, Cloud Computing is a new paradigm trend in network environments that handles and manages a vast number of users by sharing services and data, for achieving this mission; safety and security of shared services and data are the main concerns for this type of environment. Intrusion Detection is an effective technique used to deal with security violations in such environment. Here, an Anomaly Intrusion Detection model of cloud environment will be proposed which based on using hybrid artificial intelligent algorithms; Hopfield neural networks simulated annealing.
