Cloud computing is a modern style of advance and modernization in network environment which takes the advantage of a various wire and wirelss technologies as distributed, and parallel processing which oriented to service architecture. The E-government services are concerned about sharing existing resources. E-governments are available online and they have to adapt new technology that will enhance the service provided to their citizens. This paper focuses on cloud computing and e-government concepts and identifies the ways for implementing cloud computing in Jordanian e-government through a set of stages regarding the main challenges for this adaptation

Cloud Computing is a modernize computer services in 21 century. This system has some of similarities with distributed systems, through using network environment features. Therefore the security requirement is one of most critical issues in this type of environment. Because of vast number of online users over network with times, the possibility for attacker or malicious actions to perform destruction actions becomes profitable and worthy. One of the major security encounters and challenges in cloud environment is the detection of possible attempts of attacks. For detecting these malicious activities especially Denial of Service (DoS) attack, this paper will propose Learning Classifier System for Intrusion Detection System (LCS-IDS) to detect DoS in cloud environment attacks by taking advantage of learning from attacks themselves and simulate possible DoS attacks through Genetic Algorithm, generator, to rise detection rate compared with other systems in this field.
