I truly believe we have to change our thinking of cybersecurity for the digital age. We have to move from an IT security towards a secure IT/OT paradigm.
What does this mean in detail?
Let’s start with the past. The Information Technology was a very clear structured world but over the time we saw the first attacks upcoming. At this point, it was enough to add a virus scanner and professional perimeter protection.
Today we see a very complex environment with all kind of heterogeneous IT and OT components working together.
Cybersecurity answered this digitalization challenge with implementing more and more security technology… If we see new attacks, we would answer them in the same old manner as we did in the past…. which would lead to an even more complexity, with all the downsides related… hard to handle and to maintain!
In the future… a modern security architecture must adapt these new circumstances. Essential elements here are a real-time “Identity/Access Management” of humans, devices and data. Plus, a solid information protection based on “strong encryption” and for the connections between, we need to implement new concepts like “Zero Trust Networks”.
