According to a report by the Government Accountability Office, the Federal Aviation Administration has a severe deficit in how it secures its own computer networks:

The Federal Aviation Administration has fallen short in its efforts to protect the national air traffic control system from terrorists or others who might try to hack into the computers used to direct planes in flight, according to a government report released Monday.

The Government Accountability Office report credited the FAA with taking steps to deter hackers but concluded that “significant security control weaknesses remain, threatening the agency’s ability to ensure the safe and uninterrupted operation of the national airspace.”

This should come as no surprise to those in the industry, but probably would scare the average layman. It is amazing how much work the U.S. government needs to do to properly security its own networks.
