The Department of Homeland Security is warning San Francisco International Airport to keep a closer eye on its data.
A report from the department looked specifically at SFO's information technology. The report did not find any new hacks, but did point out human error -- things like doors left open -- may put SFO servers stored with data at risk.
The challenge is that technology advances don't always go hand in hand with security protocols, and the result is vulnerability gaps," said Michael McNerney with the Truman Security Project.
SFO officials declined to comment on the report.
