The news these days in security is mostly “doom and gloom”. Just consulting a site like DatalossDB.org is enough to depress even the most hardened security professional. However, there are technology advances happening all around us - some which may lead to new security issues, and others that may help security teams out enormously.
I’m willing to argue that virtualization technology falls into the latter category on most counts. Sure, there are flaws in virtualization software, and new attack vectors (the hypervisor, management tools, etc.).
