Cyber Word of the Week: IOT Devices

The Internet of Things (IoT) has exploded in recent years, transforming the way we live and work. But what exactly are IoT devices, and why are they a cybersecurity concern?

IoT devices are physical objects embedded with sensors, software, and connectivity that allow them to exchange data over the internet or a network.** These devices are now found everywhere, from smart homes to industrial systems. While they bring convenience and automation, they also introduce significant security risks if not properly configured.

Without hardening, IoT devices can become easy entry points for attackers. Common vulnerabilities include unchanged default credentials, weak encryption, and exposure to the public internet.

Examples of IoT devices include:

• Appliances (e.g., smart washers, dryers, refrigerators, ovens)
• Thermostats (e.g., Nest, Ecobee)
• Voice Assistants (e.g., Amazon Alexa, Google Home)
• Security Cameras
• Smart TVs
• Smartwatches and Fitness Trackers
• Smart Doorbells and Locks
• Industrial IoT (IIoT) devices used in manufacturing and infrastructure 

Cyber Tip:

To secure IoT devices:

• Always change default usernames and passwords. 
• Disable unnecessary features.
• Keep firmware updated. 
• Segment IoT devices on a separate network from your critical systems.

Final Thoughts

As more devices become “smart,” understanding IoT security is no longer optional; it’s essential. Stay informed and proactive to prevent your connected devices from becoming a threat.
