With all their economical advantages, the shared, large-scale cloud infrastructure introduces new security threats, and also amplifies well-known security risks. New challenges emerge with the emergence of edge and IoT devices interacting regularly with public clouds. This project is focused on designing techniques to protecting cloud users against emerging threats experienced by public clouds. We have designed an auditing framework that provides strong guarantees to cloud users about the security of their cloud resources. We use techniques from applied cryptography and machine learning for creating multi-layer defenses and improving the security of public clouds.
