Hi. Thank you to Steve Clemons for allowing me to guest blog on The Washington Note. I write about security, and will comment on any such issues that come up in the next week. I'll also provide links to essays I've already written, because the same security topics come up again and again.

Like data mining and terrorism:

In the post-9/11 world, there's much focus on connecting the dots. Many believe data mining is the crystal ball that will enable us to uncover future terrorist plots. But even in the most wildly optimistic projections, data mining isn't tenable for that purpose. We're not trading privacy for security; we're giving up privacy and getting no security in return.

Bruce Schneier is a prolific writer on security issues, with eight books -- including Beyond Fear: Thinking Sensibly About Security in an Uncertain World -- and dozens of articles to his name. He blogs at schneier.com.
