San Francisco, Feb 21 (IANS): Seven in 10 organisations have reported either a successful or attempted hack to their systems via their Internet of Things (IoT) devices, revealed a new survey.

According to the survey conducted by Extreme Networks, IoT is barrelling toward the enterprise, but organisations remain highly vulnerable to IoT-based attacks, Dark reading recently reported.

It surveyed 540 IT professionals across industries in North America, Europe, and Asia Pacific, and found that 84 per cent of organisations have IoT devices on their corporate networks.

The survey also highlighted that enterprises underestimate insider threats: 55 per cent of IT professionals believe the main risk of breaches comes mostly from outside the organisation and over 70 per cent believe they have complete visibility into the devices on the network.
