Cisco picked up IronPort today for a nice chunk of change. This helps to plug the messaging content hole in Cisco's "security in the network" offering. Given that IronPort's revenue's were probably around $100m, it keeps the multiple for acquisitions in the security and anti-spam product space up at around 8 to 10. This is a good thing.

New Blog: Matt Blaze's Exhaustive Search

Making money on stock spam.

Spam Stock Symbols

There have been many blog posts that basically say making money on stock spam is impossible, but I have to disagree. Sure, if you were to go long on the securities, you will lose a fortune. Over the short term, however, the spammers appear to be making a mint. I wrote a short article for an upcoming issue of IEEE Security and Privacy that essentially says that there is so much money being made on thinly traded equities by spammers that it is driving innovation in spam generation. I'll throw up a post once the magazine hits the presses.

Softtware diversity discussion over at nCircle

Originally uploaded by xem39.
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.
