Schneier on Security: Airplane Security I know quite a lot about this. I was a member of the government’s Secure Flight Working Group on Privacy and Security. We looked at the TSA’s program for matching airplane passengers with the terrorist watch list, and found a complete mess: poorly defined goals, incoherent design criteria, no clear system architecture, inadequate testing. (Our report was on the TSA website, but has recently been removed – “refreshed” is the word the organization used – and replaced with an “executive summary” (.doc) that contains none of the report’s findings. The TSA did retain two (.doc) rebuttals (.doc), which read like products of the same outline and dismiss our findings by saying that we didn’t have access to the requisite information.) Our conclusions match those in two (.pdf) reports (.pdf) by the Government Accountability Office and one (.pdf) by the DHS inspector general.

That’s right; the TSA is disappearing our report.
