An interesting write-up on software diversity popped up on the nCircle
blog. In the past, this sort of crazy talk
in industry caused authors to lose their jobs
. Leveraging diversity to increase the attack tolerance of a network received attention in places relatively insulated from industry politics; I did some work for my Ph.D. that showed that the allocation of diversity could be expressed as a graph theory
problem as well as it being an effective method for slowing a virus
. Tim Keanini
isn't trying to point fingers but is attempting to describe economically efficient means by which diversity can be realized in today's data centers.
