Samirbous 5ecede016d [New] Kubernetes Admission Webhook Created or Modified (#6078)
* [New] Kubernetes Admission Webhook Created or Modified

Detects creation, modification, or deletion of Kubernetes MutatingWebhookConfigurations or ValidatingWebhookConfigurations
by non-system identities. Admission webhooks intercept every API request matching their rules before persistence, giving an
attacker powerful capabilities: injecting malicious sidecars into every new pod via a mutating webhook, blocking security
tooling deployments via a validating webhook, or silently exfiltrating pod specifications to an external server.  Webhook manipulation is a stealthy persistence and defense evasion technique because the webhook configuration itself looks benign in kubectl output while actively modifying or intercepting all matching Kubernetes API traffic.

* Update non-ecs-schema.json

* Update persistence_kubernetes_admission_webhook_created_or_modified.toml
