In this paper, we outline a possible comprehensive solution for binary-based attacks, using virtual machines, machine descriptions, and randomization to achieve broad heterogeneity at the machine level. This heterogeneity increases the ``cost'' of broad-based binary attacks to a sufficiently high level that they cease to become feasible.  The convergence of several recent technologies appears to make our approach achievable at a reasonable cost, with only moderate run-time overhead. </style></abstract></record></records></xml>
