Abstract
As virtual machines become pervasive users will be able to
create, modify and distribute new "machines" with unprecedented
ease. This flexibility provides tremendous benefits for
users. Unfortunately, it can also undermine many assumptions
that today's relatively static security architectures rely on about
the number of hosts in a system, their mobility, connectivity, patch
cycle, etc.
We examine a variety of security problems virtual computing
environments give rise to. We then discuss potential directions for
changing security architectures to adapt to these demands.
