So what conference was on in this auditorium before NSConference? Well, why don’t we just read the documents they left behind?
Ooops. While there’s nothing at higher clearance than Unrestricted inside, all of the content is marked internal eyes only (don’t worry, feds, I didn’t actually pay too much attention to the content. You don’t need to put me on the no-fly list). There’s an obvious problem though: if your government agency has the word “security” in its name, you should take care of security. Leaving private documentation in a public conference venue does not give anyone confidence in your ability to manage security issues.
