Sure enough, someone filed a report with the above-mentioned Information Assurance Officer, who reported in turn to Purdue’s representative at the Defense Security Service. By the terms of its Pentagon agreement, Purdue was officially obliged to be shocked to find that spillage is going on at a talk about Snowden and the NSA. Three secret slides, covering perhaps five of my ninety minutes on stage, required that video be wiped in its entirety.
This was, I think, a rather devout reading of the rules. (Taken literally, the rules say Purdue should also have notified the FBI. I do not know whether that happened.) A more experienced legal and security team might have taken a deep breath and applied the official guidance to “realistically consider the potential harm that may result from compromise of spilled information.”
