|

You can choose to
|
||||
* run kube-bench from inside a container (sharing PID namespace with the host)
|
||||
* run a container that installs kube-bench on the host, and then run kube-bench directly on the host

* install the latest binaries from the [Releases page](https://github.com/aquasecurity/kube-bench/releases),

||||
* install the latest binaries from the [Releases page](https://github.com/aquasecurity/kube-bench/releases), though please note that you also need to download the config and test files from the `cfg` directory

kube-bench includes a set of test files for Red Hat's OpenShift hardening guide for OCP 3.10 and 3.11. To run this you will need to specify `--benchmark rh-07`, or `--version ocp-3.10` or `--version ocp-3.11`
|
||||
|
||||
when you run the `kube-bench` command (either directly or through YAML).
|
||||
|
||||
### Running in an GKE cluster
|
||||
| CIS Benchmark | Targets |
|
||||
|---|---|
|
||||
| gke-1.0| master, controlplane, node, etcd, policies, managedservices |
|
||||
|
||||
kube-bench includes benchmarks for GKE. To run this you will need to specify `--benchmark gke-1.0` when you run the `kube-bench` command.
|
||||
|
||||
To run the benchmark as a job in your GKE cluster apply the included `job-gke.yaml`.
|
||||
|
||||
```
|
||||
kubectl apply -f job-gke.yaml
|
||||
```
|
||||
|
||||
## Output
|
||||
|
||||
There are three output states:
|
||||
- [PASS] and [FAIL] indicate that a test was run successfully, and it either passed or failed.
|
||||
- [WARN] means this test needs further attention, for example it is a test that needs to be run manually.
|
||||
There are four output states:
|
||||
- [PASS] indicates that the test was run successfully, and passed.
|
||||
- [FAIL] indicates that the test was run successfully, and failed. The remediation output describes how to correct the configuration, or includes an error message describing why the test could not be run.
|
||||
- [WARN] means this test needs further attention, for example it is a test that needs to be run manually. Check the remediation output for further information.
|
||||
- [INFO] is informational output that needs no further action.
|
||||
|
||||
Note:
|
||||
- If the test is Manual, this always generates WARN (because the user has to run it manually)
|
||||
- If the test is Scored, and kube-bench was unable to run the test, this generates FAIL (because the test has not been passed, and as a Scored test, if it doesn't pass then it must be considered a failure).
|
||||
- If the test is Not Scored, and kube-bench was unable to run the test, this generates WARN.
|
||||
- If the test is Scored, type is empty, and there are no `test_items` present, it generates a WARN.
|
||||
- If the test is Scored, type is empty, and there are no `test_items` present, it generates a WARN. This is to highlight tests that appear to be incompletely defined.

|

## Troubleshooting
|
||||
|
||||
Running `kube-bench` with the `-v 3` parameter will generate debug logs that can be very helpful for debugging problems.
|
||||
|
||||
If you are using one of the example `job*.yaml` files, you will need to edit the `command` field, for example `["kube-bench", "-v", "3"]`. Once the job has run, the logs can be retrieved using `kubectl logs` on the job's pod.
|
||||
|
||||
## Test config YAML representation
|
||||
|
||||
The tests (or "controls") are represented as YAML documents (installed by default into `./cfg`). There are different versions of these test YAML files reflecting different versions of the CIS Kubernetes Benchmark. You will find more information about the test file YAML definitions in our [documentation](docs/README.md).

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

||||
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.
|
||||
|
||||
5.7.1 Follow the documentation and create namespaces for objects in your deployment as you need
|
||||
them.
|
||||
|
||||
5.7.2 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
|
||||
|
||||
5.7.3 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.
