ThingsNext in the blog series “IoT Device Security Considerations and Security Layers” is Sensors and Instruments.

There are many different sensor types ranging from the consumer available to those used in industry and specialised, e.g:

  • Barometric Pressure sensor
  • Temperature sensor
  • Altitude sensor
  • Colour sensor
  • Accelerometer sensor
  • Compass sensor
  • Humidity sensor
  • Proximity sensor
  • Motion sensor
  • Light sensor
  • Roation sensor
  • Water sensor
  • Heat sensor

Sensors will typically be connected hard wired or remote.

Security for Wired sensors will be inherently secure as the connectivity is over a physical wire.

Where there is wireless connectivity the type of wireless used should be considered with security in mind. This is called a WSN (Wireless Sensor Network)

The list of considerations could be listed as:

  • Wireless Protocol
  • Authentication
  • Encryption
  • Pairing
  • Signal strengths and limitations
  • Certificates

Some good white papers that cover WSN’s and security considerations are:
