The growth in the popularity of laptop and handheld devices, coupled with
the increase in use of wireless technologies, is driving mobile computing
closer to the ubiquitous presence predicted by early visionaries. The
downside to the readily available technology is that it is equally
accessible to adversaries for use against us. Thus there is a growing
need for better security for mobile computing. This tutorial surveys
some of the general issues in computer security, then focuses on the
security mechanisms available for several popular mobile technologies.
