Mobile security is at the top of every company’s worry list these days — and for good reason: Nearly all workers now routinely access corporate data from smartphones, and that means keeping sensitive info out of the wrong hands is an increasingly intricate puzzle. The stakes, suffice it to say, are higher than ever: The average cost of a corporate data breach is a whopping $3.86 million, according to a 2018 report by the Ponemon Institute. That’s 6.4 percent more than the estimated cost just one year earlier. 

While it’s easy to focus on the sensational subject of malware, the truth is that mobile malware infections are incredibly uncommon in the real world — with your odds of being infected significantly less than your odds of being struck by lightning, according to one estimate. That’s thanks to both the nature of mobile malware and the inherent protections built into modern mobile operating systems.

The more realistic mobile security hazards lie in some easily overlooked areas, all of which are only expected to become more pressing in the coming year:

1. Data leakage

It may sound like a diagnosis from the robot urologist, but data leakage is widely seen as being one of the most worrisome threats to enterprise security as we head into 2019. Remember those almost nonexistent odds of being infected with malware? Well, when it comes to a data breach, companies have a nearly 28 percent chance of experiencing at least one incident in the next two years, based on Ponemon’s latest research — odds of more than one in four, in other words.

What makes the issue especially vexing is that it often isn’t nefarious by nature; rather, it’s a matter of users inadvertently making ill-advised decisions about which apps are able to see and transfer their information.

“The main challenge is how to implement an app vetting process that does not overwhelm the administrator and does not frustrate the users,” says Dionisio Zumerle, research director for mobile security at Gartner. He suggests turning to mobile threat defense (MTD) solutions — products like Symantec’s Endpoint Protection Mobile, CheckPoint’s SandBlast Mobile, and Zimperium’s zIPS Protection. Such utilities scan apps for “leaky behavior,” Zumerle says, and can automate the blocking of problematic processes.
