Explanation
Introduction
The Internet of Things (IoT) extends Internet connectivity beyond traditional devices like desktop and laptop computers, smartphones, and tablets to a diverse range of devices and everyday things that use embedded technology to communicate and interact with the external environment, all via the Internet.
EXAMPLE: IoT devices may include connected security systems, thermostats, cars, electronic appliances, lights in household and commercial environments, alarm clocks, speaker systems, and vending machines.
The IoT can be described as an extension of the Internet and other network connections to different sensors and devices—or "things"—affording even simple objects, such as lightbulbs, locks, and vents, a higher degree of computing and analytical capabilities.
CAUTION: Manufacturers may hard code backdoor accounts that cannot be removed, allowing them to sign in to the device. Only purchase these devices if there are no other alternatives.
Before purchasing an IoT device
- Look for an alternative that the TTU IT Division has purchased.
- Explore all options and find the best one.
- Choose a reputable vendor from which to purchase IoT devices.
- Choose a device with some form of network management.
After purchasing an IoT device
- We recommend that you change the default administrator username and password on the device.
- Disable unused accounts.
- Do not just plug-and-play.
- Restrict communications to systems that will use the device.
- Enable encrypted communication.
- Disable unused or insecure services (FTP, Telnet, etc.).
- Enable automatic updates when possible.
