|
By default, Kubernetes allows all ingress and egress traffic to and from pods within a cluster. A "default" NetworkPolicy resource for a namespace should be used to deny all ingress traffic to the pods in that namespace. Additional NetworkPolicy resources can then be configured to allow desired traffic to application pods.
