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.
Two of the most important aspects of cybersecurity are network detection and response (NDR) and endpoint detection and response (EDR). While on the surface, there may appear to be similarities between the two, there are some key differences.
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.
Critical infrastructure refers to those vital systems, networks, and assets whose incapacitation or destruction would have a debilitating effect on national security, the economy, public health, or any combination thereof. In the U.S., the Department of Homeland Security (DHS) has demarcated 16 specific critical infrastructure sectors. These sectors serve as the pillars that support the nation's day-to-day operations and its citizens' way of life.
