SAN ANTONIO — I think I can skip any airing of “Halloween” this Friday. Cybersecurity expert Theresa Payton did far more to scare me than any masked, machete-wielding psychopath could ever do.

Payton, who was CIO for President George W. Bush from 2006 to 2008, delivered a wake-up call to the 800-plus CIOs and technology experts gathered for CHIME’s Fall Forum.

“You are going to get breached,” she said in no uncertain terms. “All systems are hackable. You need to think differently and be prepared for the worst."

During her 45-minute speech, Payton, CEO of consultancy Fortalice Solutions, rattled off various stats about cyberattacks — like the fact that 45 percent of reported breaches in 2013 were in health care. But it wasn’t all doom and gloom. She laid out a series of tips hospital leaders can follow to minimize the likelihood of a breach and, more realistically, the aftermath of one.

For instance, start conducting behavioral analytics on employees and vendors and get a baseline. That way, when something irregular pops up, like excessive downloads or other activity, red flags will go up. If Target had had such a program in place, officials may have caught unusual behavior at the HVAC vendor where its breach originated, she claimed.
