The rise in cyber attacks, whether at Yahoo or Equifax, is shedding light on the need for increased security for businesses. This week, a new bug known as "Krack," which lets hackers access secure wifi, is being called a "vulnerability." And it's brought even bigger problems to light. Alex Cho, Vice President and General Manager of Commercial PCs at HP, says end point devices including PCs and printers are increasingly the focus of these cyber attacks. Cho highlights that businesses need to be aware, and understand how unprotected their devices in the workplace can be. HP is working with businesses to create better policies to improve security. Cho says companies need to be extra vigilant about protecting security for end point devices.
