A Framework for Realizing Security on Demand in Cloud Computing

In this paper we present our vision for Security on Demand in cloud computing: a system where cloud providers can offer customized security for customers' code and data throughout the term of contract. Security on demand enables security-focussed competitive service differentiation and pricing, based on a threat model that matches the customer's security requirements for the virtual machine he is leasing. It also enables a cloud provider to bring in new secure servers to the data center, and derive revenue from these servers, while still using existing servers. We show a framework where customers' security requests can be expressed and enforced by leveraging the capabilities of servers with different security architectures.
