Security Problems with Controlled Access Systems

Schneier on Security: Security Problems with Controlled Access Systems

There was an interesting security tidbit in this article on last week's post office shooting:

The shooter's pass to access the facility had been expired, officials said, but she apparently used her knowledge of how security at the facility worked to gain entrance, following another vehicle in through the outer gate and getting other employees to open security doors.

This is a failure of both technology and procedure. The gate was configured to allow multiple vehicles to enter on only one person's authorization -- that's a technology failure. And people are programmed to be polite -- to hold the door for others.

SIDE NOTE: There is a common myth that workplace homicides are prevalent in the United States Postal Service. (Note the phrase "going postal.") But not counting this event, there has been less than one shooting fatality per year at Postal Service facilities over the last 20 years. As the USPS has more than 700,000 employees, this is a lower rate than the average workplace.
