--kubelet-certificate-authority parameter to the path to the cert file for the certificate authority.
--kubelet-certificate-authority=<ca-string>
1.2.9 Follow the Kubernetes documentation and set the desired limits in a configuration file.
Then, edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml
and set the below parameters.
--enable-admission-plugins=...,EventRateLimit,...
--admission-control-config-file=<path/to/configuration/file>

SecurityContextDeny, unless PodSecurityPolicy is already in place.
--enable-admission-plugins=...,SecurityContextDeny,...
1.2.15 Follow the documentation and create Pod Security Policy objects as per your environment.
Then, edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml
on the master node and set the --enable-admission-plugins parameter to a
value that includes PodSecurityPolicy:
--enable-admission-plugins=...,PodSecurityPolicy,...
Then restart the API Server.
1.2.20 Edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml
on the master node and set the below parameter.

== Remediations policies ==
5.1.1 Identify all clusterrolebindings to the cluster-admin role. Check if they are used and
if they need this role or if they could use a role with fewer privileges.
Where possible, first bind users to a lower privileged role and then remove the
clusterrolebinding to the cluster-admin role :
kubectl delete clusterrolebinding [name]
5.1.2 Where possible, remove get, list and watch access to secret objects in the cluster.
5.1.3 Where possible replace any use of wildcards in clusterroles and roles with specific
objects or actions.
5.1.4 Where possible, remove create access to pod objects in the cluster.
5.1.5 Create explicit service accounts wherever a Kubernetes workload requires specific access
to the Kubernetes API server.
Modify the configuration of each default service account to include this value
automountServiceAccountToken: false
5.1.6 Modify the definition of pods and service accounts which do not need to mount service
account tokens to disable it.
5.1.7 Remove the system:masters group from all users in the cluster.
5.1.8 Where possible, remove the impersonate, bind and escalate rights from subjects.
5.2.1 Create a PSP as described in the Kubernetes documentation, ensuring that
the .spec.privileged field is omitted or set to false.
5.2.2 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.hostPID field is omitted or set to false.
5.2.3 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.hostIPC field is omitted or set to false.
5.2.4 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.hostNetwork field is omitted or set to false.
5.2.5 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.allowPrivilegeEscalation field is omitted or set to false.
5.2.6 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.runAsUser.rule is set to either MustRunAsNonRoot or MustRunAs with the range of
UIDs not including 0.
5.2.7 Create a PSP as described in the Kubernetes documentation, ensuring that the
.spec.requiredDropCapabilities is set to include either NET_RAW or ALL.
5.2.8 Ensure that allowedCapabilities is not present in PSPs for the cluster unless
it is set to an empty array.
5.2.9 Review the use of capabilites in applications running on your cluster. Where a namespace
contains applicaions which do not require any Linux capabities to operate consider adding
a PSP which forbids the admission of containers which do not drop all capabilities.
5.3.1 If the CNI plugin in use does not support network policies, consideration should be given to
making use of a different plugin, or finding an alternate mechanism for restricting traffic
in the Kubernetes cluster.
5.3.2 Follow the documentation and create NetworkPolicy objects as you need them.
5.4.1 if possible, rewrite application code to read secrets from mounted secret files, rather than
from environment variables.
5.4.2 Refer to the secrets management options offered by your cloud provider or a third-party
secrets management solution.
5.5.1 Follow the Kubernetes documentation and setup image provenance.
5.7.1 Follow the documentation and create namespaces for objects in your deployment as you need
them.
5.7.2 Use security context to enable the docker/default seccomp profile in your pod definitions.
An example is as below:
securityContext:
seccompProfile:
type: RuntimeDefault
5.7.3 Follow the Kubernetes documentation and apply security contexts to your pods. For a
suggested list of security contexts, you may refer to the CIS Security Benchmark for Docker
Containers.
5.7.4 Ensure that namespaces are created to allow for appropriate segregation of Kubernetes
resources and that all new resources are created in a specific namespace.
