policies.kyverno.io/description: >- | ||
Sysctls can disable security mechanisms or affect all containers on a | ||
host, and should be disallowed except for an allowed "safe" subset. A | ||
sysctl is considered safe if it is namespaced in the container or the | ||
Pod, and it is isolated from other Pods or processes on the same Node. | ||
This policy ensures that only those "safe" subsets can be specified in | ||
a Pod. | ||
