Analysis of Insiders Attack Mitigation Strategies

AbstractInsider attacks become a severe threat to organizations. The emergence of Cloud computing that provides computing as a utility has attracted organizations to store their sensitive data remotely by subscribing the virtual storage from Cloud service provider. While data outsourcing relieves the data owners from burden of local data storage maintenance and security, the steps of embracing Cloud storage service has led to security problems. With the services provided by Cloud service provider that can be extended from Cloud user to Private Cloud and expanded to Public Cloud, there are many possibilities that malicious insider attacks may occur to exploit the weaknesses of Cloud systems. Until now there are no perfect mitigation strategies that can be relied on to solve the threats. We describe the Cloud computing and security issues, discuss about malicious insiders attack in Cloud computing and analyses the existing mitigation strategies and techniques to reduce malicious insiders threats in Cloud computing
