I scheduled a one hour Analyst discussion with Trent Henry of Burton Group on the subject of trends in Hypervisor Security; with respect to getting the apprprate balance of risk mitigation (i.e. threat vs. investment in threat response using technology and practice).
Specifically, my query to setup the discussion was:
"The costs associated with deploying and maintaining completely separate physical visualization infrastructures, for applications which access sensitive data, is making it extremely difficult to make a server virtualization service financially viable. We are revisiting the risk assessment vs. systems design and administration criteria, to consider whether good (enough) security could be reasonably provided with less onerous and costly controls."
