Countering IoT Security Issues: an Enterprise Guide

Why IoT poses a different kind of risk

How to protect against IoT security issues

  • IoT devices should be treated differently to other network devices from a security perspective. Ringfencing IoT devices and limiting the parts of your network that IoT devices have access to is a good start.
  • Ensure network authentication is required for every single device. Devices should not be allowed access to gateways and network applications unless necessary. Also, ensure that strong passwords are always used and enable 2FA where possible.
  • Apply network encryption everywhere, including Transport Security Layer (TLS), as this can ensure that data transmitted by IoT devices remains confidential.
  • Physically block devices: if a device is not needed, turn off the power. Block ports on exposed devices as these can provide entry points.
    As far as practically possible, make a serious attempt to catalogue IoT devices so that your enterprise can update firmware and manage patches.
  • Watch out for IoT where it’s least expected, such as in consumer electronics like fridges and conference room TV sets. Manage the connectivity of these devices carefully, blocking network access where it is not needed.
