IoT security (internet of things security) is the technology segment focused on safeguarding connected devices and networks in IoT. IoT involves adding internet connectivity to a system of interrelated computing devices, mechanical and digital machines, objects, animals and people. Each thing has a unique identifier and the ability to automatically transfer data over a network. However, enabling devices to connect to the internet opens them up to serious vulnerabilities if they aren’t properly protected.

The term IoT is extremely broad, and as this technology continues to evolve, the term only becomes broader. From watches to thermostats to video game consoles, nearly every technological device can interact with the internet, or other devices, in some capacity.

IoT security is even broader than IoT, resulting in a variety of methodologies falling under that umbrella. Application programming interface (API) security, public key infrastructure (PKI) authentication and network security are just a few of the methods IT can use to combat the growing threat of cybercrime and cyberterrorism rooted in vulnerable IoT devices.

Why is IoT security important?

Due to the unconventional manufacturing of IoT devices and the vast amount of data they handle, there’s a constant threat of cyber attacks. Several high-profile incidents where a common IoT device was used to infiltrate and attack the larger network have drawn attention to the need for IoT security.
