Princeton Docket # 15-3171-1
Researchers at Princeton University, Department of Electrical Engineering, have developed a distributed architecture to monitor and attest the security health of cloud customers' virtual machines (VMs) in a cloud computing system.
Cloud providers want to monitor VMs to provide a secure and efficient computing environment to their customers. But there are few security health monitoring mechanisms in today's clouds. In addition, current attestation mechanisms are not very powerful or efficient. Current attestation techniques only focus on the integrity of a platform’s software stack.
This invention is a distributed architecture, called CloudMonatt. It can provide monitoring services and attestation of different security properties, based on the customers' demand. It can also enable customers to monitor the VM at different stages during the VM's lifecycle, either one-time or periodically. The CloudMonatt framework can also provide mitigations to the vulnerabilities in the system. It has the potential for being deployed in commercial cloud computing centers−both public clouds and private clouds. More importantly, CloudMonatt is easy to deploy and requires minimal hardware addition, since it leverages commercial cloud computing software (OpenStack) and hardware (TPM, monitoring tools, etc.).
• Cloud computing centers
1. Detects and monitors the Security health of VMs
2. Produces unforgeable attestation reports
3. Protects VMs from security breaches
• Security monitoring
• Attestation of security properties based on customers’ demand
• Minimal or no hardware addition to the current system
