If you’re waiting for a flight at San Diego International, grab a good book and leave your email for later. A new study looking at the security of public Wi-Fi at America’s 45 busiest airports ranked San Diego as the most vulnerable, with an 11 percent probability of connecting to a high-risk network, and a 30 percent probability of connecting to a medium-risk network.
The study, conducted by cloud security company Coronet, looked at data over a five-month period, starting in January 2018, then gave each airport a threat index score indicating the probability of an attacker on the public network. The higher the score, the higher the risk
“In an attempt to maximize the traveler experience, the vast majority of airports now provide free or low-cost Wi-Fi for passengers to connect to for work, entertainment or a combination thereof,” the Coronet report says. “Unfortunately, Wi-Fi security is often sacrificed by airport operators in exchange for consumer convenience, leaving networks unencrypted, unsecured, or improperly configured.”
According to Coronet, here are the 10 most cyber-vulnerable airports in the U.S. and their Threat Index Score:
San Diego International, 10
John Wayne Airport-Orange County Airport, Santa Ana, Calif., 8.7
William P. Hobby Airport, Houston, 7.5
Southwest Florida International Airport, Fort Myers, Fla., 7.1
Newark (N.J.) Liberty International Airport, Newark, N.J., 7.1
Dallas Love Field, 6.8
Phoenix Sky Harbor International Airport, 6.5
Charlotte (N.C.) Douglas International Airport, 6.4
Detroit Metropolitan Wayne County Airport, 6.4
Logan International Airport, Boston, 6.4
The airport with the most-secure public Wi-Fi network, according to Coronet, is Chicago Midway International, with a Threat Index Score of 4.5, followed by Raleigh Durham International (4.9), Washington Dulles International (5.1), and Nashville International (5.1).
