### Description{% #description %}

Containers and initContainers should configure drop capabilities in their `securityContext`. The rule requires that each container defines `securityContext.capabilities` with a `drop` attribute; missing `securityContext`, `capabilities`, or `drop` is reported. This enforces least-privilege by removing unnecessary Linux capabilities.
