kube-bench is a Go application that checks whether Kubernetes is deployed securely by running the checks documented in the [CIS Kubernetes Benchmark](https://www.cisecurity.org/benchmark/kubernetes/).
|
||||
|
||||
Note that it is impossible to inspect the master nodes of managed clusters, e.g. GKE, EKS and AKS, using kube-bench as one does not have access to such nodes, although it is still possible to use kube-bench to check worker node configuration in these environments.
|
||||
|
||||
Tests are configured with YAML files, making this tool easy to update as test specifications evolve.
|
||||
|
||||
### Please Note
|
||||
|
||||
1. kube-bench implements the [CIS Kubernetes Benchmark](https://www.cisecurity.org/benchmark/kubernetes/) as closely as possible. Please raise issues here if kube-bench is not correctly implementing the test as described in the Benchmark. To report issues in the Benchmark itself (for example, tests that you believe are inappropriate), please join the [CIS community](https://cisecurity.org).
|
||||
|
||||
1. There is not a one-to-one mapping between releases of Kubernetes and releases of the CIS benchmark. See [CIS Kubernetes Benchmark support](#cis-kubernetes-benchmark-support) to see which releases of Kubernetes are covered by different releases of the benchmark.

There is also preliminary support for Red Hat's OpenShift Hardening Guide for 3.10 and 3.11. Please note that kube-bench does not automatically detect OpenShift - see below.

||||
NetworkPolicy that selects all pods but does not allow any traffic:
|
||||
apiVersion: networking.k8s.io/v1
|
||||
kind: NetworkPolicy
|
||||
metadata:
|
||||
name: default-deny
|

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.
|
||||
|
||||
5.2.1 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 runnning 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.
|
||||
|
||||
5.6.1 Follow the documentation and create namespaces for objects in your deployment as you need
|
||||
them.
|
||||
|
||||
5.6.2 Seccomp is an alpha feature currently. By default, all alpha features are disabled. So, you
|
||||
would need to enable alpha features in the apiserver by passing "--feature-
|
||||
gates=AllAlpha=true" argument.
|
||||
Edit the /etc/kubernetes/apiserver file on the master node and set the KUBE_API_ARGS
|
||||
parameter to "--feature-gates=AllAlpha=true"
|
||||
KUBE_API_ARGS="--feature-gates=AllAlpha=true"
|
||||
Based on your system, restart the kube-apiserver service. For example:
|
||||
systemctl restart kube-apiserver.service
|
||||
Use annotations to enable the docker/default seccomp profile in your pod definitions. An
|
||||
example is as below:
|
||||
apiVersion: v1
|
||||
kind: Pod
|
||||
metadata:
|
||||
name: trustworthy-pod
|
||||
annotations:
|
||||
seccomp.security.alpha.kubernetes.io/pod: docker/default
|
||||
spec:
|
||||
containers:
|
||||
- name: trustworthy-container
|
||||
image: sotrustworthy:latest
|
||||
|
||||
5.6.3 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.
|
||||
|
||||
5.6.4 Ensure that namespaces are created to allow for appropriate segregation of Kubernetes
|
||||
resources and that all new resources are created in a specific namespace.
