Internet of Things (IoT) devices such as fitness trackers and home security cameras are growing in popularity, but many people don’t realize that these devices can also be used to attack critical infrastructure. In 2017, a group of hackers used IoT devices to launch a massive attack on the internet infrastructure provider Dyn, and they were only able to do this because they were able to exploit devices that were using default passwords.

In the realm of cybersecurity, protecting both IT (Information Technology) and OT (Operational Technology) systems is essential. Comprehending the distinctions between these systems is vital for safeguarding them against cyber threats.
