Securing Networks in the Internet of Things Era | Help Net

That shouldn’t be surprising. What is surprising is that a strong majority of respondents – 63 percent – also saw those devices and IoT in general as a threat to network security. So: IoT adoption is gaining speed, and worries about IoT security are gaining traction. The survey suggests that few IT organisations have deployed IoT-specific infrastructure, such as dedicated networks for IoT devices or management […]
