Lost laptops, emails sent to the wrong address, sensitive documents left on photocopiers, employees walking out of the building with confidential papers or storage media — these are not new sources of leaks, but they remain the most common, the study finds. “Most of these are accidental, not malicious,” Seth says.
Some employees repeat sensitive information on social networking sites such as MySpace or Facebook, while others may be overheard in a restaurant or on an airplane. An employee might be shoulder-surfed at a coffee shop or on a train, or lose an unencrypted storage device in a public place, the study observes.
The study also found some methods of leakage that may not be anticipated, such as “print screen” capabilities or photographing of screens on mobile devices. “I know it’s a tired phrase, but we’re talking about human behavior here, and the only way to correct the problem is to correct the behavior.”
