Secure cloud maintenance

Sören Bleikertz, Anil Kurmus, Zoltán A. Nagy, Matthias Schunter
2012 Proceedings of the 7th ACM Symposium on Information, Computer and Communications Security - ASIACCS '12  
To protect cloud users against such insiders, we propose a novel approach that enables a security team to protect privacy and integrity of cloud users' workloads against attacks by system administrators  ...  For manual maintenance operations, we propose five finegrained privilege levels that balance the security objectives of cloud users with the operational requirements of cloud administrators.  ...  Today, no technology can protect against insider attacks during such maintenance activities.  ...
