Cloud computing provides on-demand services over the Internet using methods that manages the amount of virtual storage. The key features of cloud computing are that user has no expensive IT infrastructure and the cost of their services is lower. Today, cloud computing integrates with industry-leading companies and other domains, encouraging the researcher to look for new technologies for advanced cloud computing. We discussed the basic features of cloud computing, security issues, threats and their solutions. It also describes several key cloud-related topics: cloud architecture structure, service and deployment model, cloud technologies, cloud security concepts, threats and attacks. In addition, Denial of Service Attacks, an emerging threat for large cloud infrastructures, discuss many open search issues related to cloud security. And a collaborative model consists of the Intrusion Detection and Prevention System functions based distributed IDS and IPS, with the use of a hybrid detection technique for addressing the problems of attacks encountered, specifically distributed attacks such as port scanning attacks and distributed internally established within a Cloud Computing environment. |
