Google Developer Kees Cook Details The Linux Kernel Self-Protection Project
At the Linux Security Summit last month, Google developer Kees Cook shared the current workings of the Kernel Self-Protection Project (KSPP). The project, he said, goes beyond user space and even beyond kernel integrity. The idea is to implement changes to help the kernel protect itself.
To understand the importance of the project, Cook said, we need to think about the multitude of devices running Linux, such as servers, laptops, cars, phones, and then consider that the vast majority of these devices are running old software, which contains bugs. Some of these devices have very long lifetimes, but the lifetime of a bug can be longer still.
