In 2016, Google developer Keith Cook launched the Kernel Self Protection Project (KSPP) to add additional layers of protection to the Linux kernel. One of the many uses of KSPP is to mitigate memory corruption.

As McCauley said, KSPP is very important for hardening Linux and improving LinuxKit, so Docker has several full-time employees working on and contributing to the project.

Landlock

several Linux Security Modules (LSMs) that provide access south africa whatsapp data policies for Linux processes. Two of the most popular are SELinux and AppArmor. SELinux was originally developed by the US National Security Agency and is now a key component of Red Hat-based Linux distributions.

LinuxKit is incubating a new LSM called Landlock, which uses extended Berkeley Packet Filters (eBPF) to plug small programs into the Linux kernel. “These eBPF programs create a context that, when integrated with the LSM plug-in, provides very robust decision making,” Docker security engineer Riyaz Faizullabhoy wrote on GitHub when adding Landlock to LinuxKit. “This is particularly well-suited for container-based computing environments.”

Landlock can be used to write policies to restrict containers' access to file descriptors that they don't own, serving as a last line of defense to limit container escapes. And that's where it can be useful for Docker container users, Faizullabh said.
