The IT/OT convergence flips the script on security. Traditional models such as the Purdue Model were designed for separation. Today’s reality demands something different: a model that ditches static boundaries and kills implicit trust. That’s where Zero Trust 2.0 for OT security comes in.
By examining the Lake Risevatnet incident through the lens of the SANS Five ICS Critical Controls, it becomes clear how established safeguards could have reduced both the likelihood of the intrusion and its operational impact.
When an attacker takes control of hospital systems, it’s not a spreadsheet that breaks. It’s the oxygen supply, the water treatment system, the temperature control in the ICU. A single digital command can ripple into the realy world: quietly, instantly, dangerously.
A newly confirmed vulnerability in train braking systems has resurfaced after more than two decades, and it’s finally getting some traction. In short, this vulnerability allows attackers to send unauthenticated radio signals that can trigger emergency brakes, putting public safety at risk.
Operational Technology (OT) refers to the hardware and software that control physical systems like factory equipment, power grids, or hospital machines. Unlike IT, which focuses on data access and user services, OT is about delivering physical products and tangible services.
