Cisco CEO: Hacking attacks about to get a lot worse

Cisco Systems Chief Executive John Chambers expects hacking attacks to become a lot worse in 2015, and he's positioning his digital networks company to take advantage of it.

"Security was bad last year," Chambers said, referring to high-profile hacks on companies such as Sony Entertainment and retailer Target. "Unfortunately, this year it's going to be much worse." As long as companies view digital security as a defense rather than an opportunity to grow with others in their industries, they will be vulnerable to malicious hacking, Chambers said. Most companies still don't know how vulnerable they are and that will play out with more high-profile hacks in coming months, he added.
