As hospitals and health care providers continue to use more electronic records, they're increasingly becoming the targets of cybercriminals. That's according to Carl Leonard, a principal security analyst for Websense, who said hackers are breaking into the computer networks of health care facilities with increasing frequency and taking valuable personal information that is often secured improperly. In 2015, Websense projects the health care industry will see a substantial increase in cyberattacks. St. Louis is home to a large health care community, with more than 25 regional hospitals accounting for more than $7.6 billion in annual revenue, according to St. Louis Business Journal research.
