  • I don’t work directly with PLCs but we do have them at my work. The main thing that makes these different from any other devices is that they typically control physical machines. Which means there is a real danger that them becoming compromised could lead to damaged equipment or even death.

    Additionally, many PLCs use older OS versions like xp because their software is notoriously out of date (if it’s working why rewrite it when that could introduce safety concerns)

    This “urgent” message from CISA does not prove that any of these devices are internet accessible just that if they are then they should be removed. If CISA wanted to require this then they would have released a binding operational directive (BOD) or an emergency directive (ED). Both of which are publicly viewable on their site.

    I have used linux the better part of a decade but have never really followed kernel development.

    What does it mean for the kernel to be “monolithic”? What would need to change in the kernel for it to no longer be considered “monolithic”?
