☑️ Prevent containers from having insecure capabilities
Capabilities permit certain named root actions without giving full root access. They are a more fine-grained permissions model, and all capabilities should be dropped from a pod, with only those required added back. Giving containers unnecessary capabilities may compromise them and allow attackers access to sensitive components.
