A Study of Various Attacks and Intrusion Detection System in Cloud

Cloud computing is the computing that uses resources either software or hardware over the Internet. It is the computing over the network. Today, almost every IT services are provided using this innovative technology. Cloud computing is the model that provides convenient on demand access of various services by using shared pool of configurable computing resources. Using of such shared pool of computing resources, this computing is targeted by various Cloud intruders, attackers and therefore exists number of new risks and threats due to its operational dependency over the network i. e. distributed environment which has number of vulnerabilities. In order to solve this security problem, there are number of security solution, models and schemes. This paper explains about security issues in cloud and focuses on various kinds of attacks such as Insider Attack, Man-in-the Middle Attack, DoS Attacks. Lastly it explains the need of effective Intrusion Detection and Prevention System in order to overcome such attacks.
