Critical infrastructure refers to essential systems and assets, both physical and virtual, whose incapacitation or destruction would significantly impact society.
This encompasses sectors like energy, water, transportation, healthcare, and financial services. As many of these infrastructures are now digitally controlled, they are vulnerable to cyber threats. 

In the ever-evolving digital landscape, one aspect that has gained significant attention is OT cybersecurity.
As our reliance on technology grows, so does the need for robust security measures, especially in the realm of operational technology (OT). But what exactly is OT cybersecurity, and why is it becoming increasingly important?

What is industrial cybersecurity? Simply put, it’s the shield that protects the computer systems and networks that are the lifeblood of vital industries like manufacturing, energy, and transportation. It’s about keeping these sectors safe from the dangerous cyber threats that could cripple their operations.

In terms of cybersecurity, a unidirectional gateway is a network appliance that allows data to flow in one direction only, from a source network to a destination network. This one-way data flow is physically enforced, making it impossible for any data to travel back from the destination network to the source network.

A data diode is a cybersecurity device that ensures secure data transfer. It’s not just another piece of security hardware; it’s a game-changer. Unlike traditional security measures, data diodes offer a unique feature: unidirectional data flow. This means that data can only move in one direction, from the source to the destination, without any possibility of a return journey.
