No-Fly List shenanigans
Just last week a five-year old boy was detained by TSA (Transportation Security Administration) because his name was similar to a suspected terrorist on the no-fly list. The reporter wrote, “A five-year-old boy was taken into custody and thoroughly searched at Sea-Tac because his name is similar to a possible terrorist alias. As the Consumerist reports, ‘When his mother went to pick him up and hug him and comfort him during the proceedings, she was told not to touch him because he was a national security risk. They also had to frisk her again to make sure the little Dillinger hadn’t passed anything dangerous weapons or materials to his mother when she hugged him.'”
On the other hand, 13 News in Indianapolis interviewed a woman, Lisa Skaggs, who described an incident two rows in front of her, where a man occupied the same seat that was assigned to another passenger. The man refused to produce his ID, only showing his boarding pass with the same seat number. The plane was finally evacuated in order to remove the recalcitrant passenger. http://www.wthr.com/Global/story.asp?S=7369309&nav=menu188_6
A United Airlines representative confirmed that the passenger’s name did not match the boarding pass. In my opinion, the most shocking statement about this incident came from a TSA official. “TSA’s Christopher White believes the system worked. ‘The fact that one of two million may not have a boarding pass that does not match and I.D., does not overly concern us when they’re exposed to all these other layers of security,’ said White.”
It’s not illegal to fly without having an ID. In fact TSA’s regulations explicitly allow for passengers to board an aircraft without an ID. You might find the experience and perspective of Joby Weeks to be interesting in this context: http://www.thetraveljunkie.ca/articles.php?articleid=146
The fact that boarding passes are an element of TSA’s security and that boarding passes may be printed from home represents a security hole in TSA’s security rules and regulations. This was documented by Senator Charles Schummer of New York, who vividly described how “Joe Terrorist” circumvents the no-fly list, in a letter dated February 11, 2005 to TSA officials.
The insecurity of “print-from-home” boarding passes was demonstrated convincingly a year ago by Christopher Soghoian, a Ph. D. student in Computer Science at Indiana University. “The FBI raided the home of Indiana University grad student Christopher Soghoian, who created a Web site that lets users forge their own airline boarding passes. Soghoian said he intended to call attention to an airport security loophole.”

There are several security principles that are illustrated in the above scenario:
- If security is not implemented properly and has glaring security weaknesses, your organization may receive intense negative attention.
- If security is not designed into the overall system, but it is added in after the fact, security holes will be present that will be difficult to patch.
- A proper view of security requires understanding the true risk that is represented by anomalous and unusual behaviors (such as understanding what a one-in-one-million anomaly potentially represents).
- Simple lists and blindly following ad-hoc rules (such as detaining five-year olds) can make your organization look ridiculous.
- When you use elements in your security system that were not designed to provide security (such as print-from-home boarding passes), you are likely to have security holes.
We don’t know why the passenger without the ID refused to present his identification documents. Here are some possible scenarios.
- He could have learned how to hack United Airlines’ reservation system.
- He could be an actual wanted fugitive who paid for or fabricated a false boarding pass.
- He could be a terrorist who was probing airline security in order to learn how to board an airplane without presenting an ID and without drawing attention to himself.
All of these possibilities show the inanity of the TSA comment: “The fact that one of two million may not have a boarding pass that does not match and I.D., does not overly concern us when they’re exposed to all these other layers of security.” We have learned at Caveon that the unusual circumstance is that which requires the greatest care and scrutiny.
A few years ago a large number of test booklets were lost. Even though the large number of lost booklets was a very small percent of the total number of printed booklets, the fact remained that those lost test booklets represented a substantial security risk to the testing program. It only takes one lost booklet to compromise an entire exam. It only takes one or two terrorists out of a million flyers to represent a significant security risk to the public safety.
Caveon Data Forensics is based on the premise that unusual and extremely anomalous data are those that should receive the greatest scrutiny. We are extremely concerned when test takers go outside the country to take tests. We are especially vigilant when tests are extremely similar, even when or especially when they represent a very small proportion of the total tests administered. From my view, the unusual and the anomalous data are those that should receive our highest attention. The comment from the TSA official suggested that such data do not represent a significant worry. In my opinion, such an attitude is short-sighted and imprudent.
