Top 10 Most Vulnerable WiFi Networks at U.S. Airports

Meeting professionals have to work while traveling, and that often requires using airport WiFi networks. But is it safe? Often, the answer is no, cautions online security platform provider Coronet. The company recently collected and analyzed five months' worth of WiFi network data from the 45 busiest airports in the country. Coronet devised a vulnerability scoring system, based on a series of security-related network factors, and assigned a threat-index score to each airport.

The following are the top 10 most vulnerable airport WiFi networks and their threat-index scores. (A score of 10 is the worst, and a risk level of 6.5 or above represents "unacceptable exposure" to risk, according to Coronet.)
1. San Diego International Airport (10)
2. John Wayne Airport-Orange County, Calif. (8.7)
3. Hobby Airport, Houston (7.5)
4. Southwest Florida, Fort Myers (7.1)
5. Newark Liberty, N.J. (7.1)
6. Dallas Love Field (6.8)
7. Phoenix Sky Harbor (6.5)
8. Charlotte Douglas, N.C. (6.4)
9. Detroit Metropolitan Wayne County (6.4)
10. Logan International, Boston (6.4)

Significant measures of risk were found at all airports studied. The least vulnerable were Chicago Midway (4.5); Raleigh Durham, N.C. (4.9); Nashville (5.1), and Washington Dulles (5.1).
