With cloud computing, customers can use a variety of computing resources whenever they need them without having to worry about maintenance. But security is one of the main issues with cloud computing. Making the move to the cloud presents end users with new security problems, especially because of shared resources that are available to other users. This study focuses on the colocation or co-resident attack, a malicious strategy in which attackers use backdoors to steal sensitive data from Virtual Machine (VM)s housed on the same server. The study investigates detection and prevention techniques for co-resident attacks. Our focus is on the Previously Selected Servers First (PSSF) VM allocation policy, which was selected because it can offer increased security while using less energy to address this problem. Later, we extend this PSSF to study its impact on the Multi-data center environment.
