Analysis of Multilevel Framework for Cloud Security

This article proposes a novel and trusted multilevel security framework for securing cloud resources used in a collaborative deployment. A secure communication protocol is also proposed for communication among the cloud resources from different Cloud Service Users (CSU) and among the non trusted groups. Two level security frameworks are Domain level and cloud service provider (CSP) level. A Domain contains a number of CSUs for the same trusted group. The Domain level security ensures and evaluates the trustworthiness of its individual CSU. The CSP level security ensures and evaluates the trustworthiness of various domains. In the proposed framework, security agents are to be deployed both at the Domain level and at the CSP level to evaluate and maintain the trust To support collaboration user must allow inbound traffics to its own Virtual Machine (VM) from VMs of other (CSU). This can be used by the agents to control access between two VMs belonging to the same domain or in two different security groups. The proposed framework ensures that the trust-level of an entire domain does not fall due to malicious activities of only a small minority of members.
