This blip is not on the current edition of the radar. If it was on one of the last few editions it is likely that it is still relevant. If the blip is older it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the radarUnderstand more

gVisor is a user-space kernel for containers. It limits the host kernel surface accessible to the application without taking away access to all the features it expects. Unlike existing sandbox technologies, such as virtualized hardware (KVM and Xen) or rule-based execution (seccomp, SELinux and AppArmor), gVisor takes a distinct approach to container sandboxing by intercepting application system calls and acting as the guest kernel without the need for translation through virtualized hardware. gVisor includes an Open Container Initiative (OCI) runtime called runsc that integrates with Docker and provides experimental support for Kubernetes. gVisor is a relatively new project and we recommend assessing it for your container security landscape.
