Tackling Insider Threat in Cloud Relational Databases

Cloud security is one of the major issues that worry individuals and organizations about cloud computing. Therefore, defending cloud systems against attacks such as insiders' attacks has become a key demand. This paper investigates insider threat in cloud relational database systems (cloud RDMS). It discusses some vulnerabilities in cloud computing structures that may enable insiders to launch attacks, and shows how load balancing across multiple availability zones may facilitate insider threat. To prevent such a threat, the paper suggests three models, which are Peer-to-Peer model, Centralized model and Mobile- Knowledgebases model, and addresses the conditions under which they work well.
