Should you be afraid of text messages?

Maria Korolov | April 2, 2015
Text messaging is just the tip of the iceberg.

Text messages are also just the tip of the app iceberg.

In addition to the SMS and MMS messaging provided by the mobile phone company, there are also messaging functions in many other applications — such as Facebook Messenger, WhatsApp, Apple iMessage, Google Hangout, and Skype. Many games, forums and other types of online communities also allow users to send private messages to one another.

"Enterprises need to protect the data that is used by apps and how it can be shared from them," said Andrew Blaich, lead security analyst at San Francisco-based Bluebox Security. "If they solve the problem at the root, then all other vectors of attack will be minimized."

There are bigger things to worry about

Employees determined to leak company secrets have plenty of options.

For example, they can just pick up their personal phones, make a voice call, and tell the secret information to their outside contact. Or they could write it on a sticky note.

"Just today, I saw an ex-employee of a company having lunch with current employees," said Mike Lloyd, CTO at Sunnyvale, Calif.-based RedSeal, Inc. "But somehow, CISO's are not rushing to bug every restaurant in town. You just write policies against foolish behavior, and you do your best to train people."
