Securing or attacking Industrial Control Systems
It turns out that Kaspersky Labs is developing a brand new operating system specifically designed to be used in embedded industrial systems and industrial control systems.
The obvious question:
"First I’ll answer the most obvious question: how will it be possible for KL to create a secure OS if no one at Microsoft, Apple, or the open source community has been able to fully secure their respective operating systems? It’s all quite simple really.
"First: our system is highly tailored, developed for solving a specific narrow task, and not intended for playing Half-Life on, editing your vacation videos, or blathering on social media. Second: we’re working on methods of writing software which by design won’t be able to carry out any behind-the-scenes, undeclared activity. This is the important bit: the impossibility of executing third-party code, or of breaking into the system or running unauthorized applications on our OS; and this is both provable and testable."
