I was unaware of this act before reading this, but I kinda like it. My current employer wants to do the absolute minimum in securing the software they develop. However, it's used at in organizations working on national energy and communications infrastructure, so it's somewhat important for it to be secure.
Meanwhile, we're way behind on updating much of our infrastructure and hardly ever check whether any of the open source libraries we use are up-to-date, nor whether they're reliable. I really hope this legislation pushes companies like mine to improve their software development practices, because I'm scared of the future.
