Securing your Internet of Things (IoT):  Google Home, Amazon Alexa, etc.

NCSAM Week 4: October 22 - 31

The Internet of Things (IoT) has made daily tasks more convenient, but often at the sacrifice of security and privacy.  IoT devices are comprised of everyday items that are Internet enabled and connect to the web. IoTs are: smart TVs, smar watches, lighting systems, thermostats, cameras, medical devices, vehicles, refridgerators, medical devices, and any THING else that connects to the network to send/receive data.  The problem with IoT is they typically do not have security controls in place to prevent misuse and they do not receive security updates to correct weaknesses, which makes them open to being hacked.  

  1. Identify Your IoT Devices: Take an inventory of your IoT devices so you know what you have and where.  This makes it easier to check with the manufacturer for updates or recalls on the device(s), when available. 
  2. Learn What and How: Read the manufacturers information guide to know what the device does and how it connects to your network as well as how it communicates across the Internet.  You may be able to restrict access on your network to reduce attacks.
  3. Change the Defaults:  When possible, change the default settings to make it more secure by disabling services you do not need or will use.  The IoT device may be sharing more information than you expect or would like.
  4. Isolate IoT Devices: Create a separate Wi-Fi network on your home router with a very strong and different password from your computer Wi-Fi network.  IoT devices provide hackers with a new attack vector and less security.  A separate Wi-Fi network will prevent an attack on IoT devices from impacting your entire home network.
