As I was in the airport on the way back from Copenhagen, BBC World News was playing on one of the displays when a familiar pop-up appeared on the bottom right hand portion of the screen. Obviously there was a networked computer sending video throughout the airport.
Although I don't know the overall network security posture of the airport, this didn't look good. Of all security hardening procedures, "Up-to-date Antivirus" is pretty high on everyone's list. Sometimes good security is simply appearing to be secure. In the military they teach you that the appearance of a hard target can deter attacks. In security we must get the little things right.
