|
||||
|
||||
**Overview**
|
||||
|
||||
[A clear and concise description of what the bug is]
|
||||
|
||||
**How did you run kube-bench?**
|
||||
|
||||
[Please specify exactly how you ran kube-bench, including details of command parameters and/or job file that you used to run it]
|
||||
|
||||
**What happened?**
|
||||
|
||||
[Please include output from the report to illustrate the problem. If possible please supply logs generated with the `-v 3` parameter.]
|
||||
|
||||
**What did you expect to happen:**
|
||||
|
||||
[Please describe what you expected to happen differently.]
|
||||
|
||||
**Environment**
|
||||
|
||||
[What is your version of kube-bench? (run `kube-bench version`)]
|
||||
|
||||
[What is your version of Kubernetes? (run `kubectl version` or `oc version` on OpenShift.)]
|
||||
|
||||
**Running processes**
|
||||
|
||||
[Please include the output from running `ps -eaf | grep kube` on the affected node. This will allow us to check what Kubernetes processes are running, and how this compares to what kube-bench detected.]
|
||||
|
||||
**Configuration files**
|
||||
|
||||
[If kube-bench is reporting an issue related to the settings defined in a config file, please attach the file, or include an extract showing the settings that are being detected incorrectly.]

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.

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/).
|
||||
|

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.

## CIS Kubernetes Benchmark support
|
||||
|
||||
kube-bench supports the tests for Kubernetes as defined in the CIS Benchmarks 1.3.0 to 1.5.0 respectively.
|
||||
kube-bench supports the tests for Kubernetes as defined in the [CIS Kubernetes Benchmarks](https://www.cisecurity.org/benchmark/kubernetes/).
|
||||
|
||||
| CIS Kubernetes Benchmark | kube-bench config | Kubernetes versions |
|
||||
|---|---|---|
|
||||
| 1.3.0| cis-1.3 | 1.11-1.12 |
|
||||
| 1.4.1| cis-1.4 | 1.13-1.14 |
|
||||
| 1.5.0 | cis-1.5 | 1.15- |
|
||||
|
||||
|
||||
By default, kube-bench will determine the test set to run based on the Kubernetes version running on the machine.
|
||||
|
||||
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.
|
||||
|
||||
| [1.5.1](https://workbench.cisecurity.org/benchmarks/4892) | cis-1.5 | 1.15- |
|
||||
| [1.6.0](https://workbench.cisecurity.org/benchmarks/4834) | cis-1.6 | 1.16- |
|
||||
| [GKE 1.0.0](https://workbench.cisecurity.org/benchmarks/4536) | gke-1.0 | GKE |
|
||||
| [EKS 1.0.0](https://workbench.cisecurity.org/benchmarks/5190) | eks-1.0 | EKS |
|
||||
| Red Hat OpenShift hardening guide | rh-0.7 | OCP 3.10-3.11 |
|
||||
|
||||
By default, kube-bench will determine the test set to run based on the Kubernetes version running on the machine, but please note that kube-bench does not automatically detect OpenShift and GKE - see the section below on [Running kube-bench](https://github.com/aquasecurity/kube-bench#running-kube-bench).
|
||||
|
||||
The test files for the various versions of CIS Benchmark can be found in directories
|
||||
with same name as the CIS Benchmark versions under `cfg/`, for example `cfg/cis-1.5`.
|
||||
## Installation
|
||||
|
||||
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),
|
||||
* compile it from source.
|
||||
* Run kube-bench from inside a container (sharing PID namespace with the host). See [Running inside a container](#running-inside-a-container) for additional details.
|
||||
* Run a container that installs kube-bench on the host, and then run kube-bench directly on the host. See [Installing from a container](#installing-from-a-container) for additional details.
|
||||
* 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. See [Download and Install binaries](#download-and-install-binaries) for details.
|
||||
* Compile it from source. See [Installing from sources](#installing-from-sources) for details.
|
||||
|
||||
## Running kube-bench
|
||||
|
||||
If you run kube-bench directly from the command line you may need to be root / sudo to have access to all the config files.
|
||||
|
||||
kube-bench automatically selects which `controls` to use based on the detected
|
||||
node type and the version of Kubernetes a cluster is running. This behavior
|
||||
can be overridden by specifying the `master` or `node` subcommand and the
|
||||
`--version` flag on the command line.
|
||||
By default kube-bench attempts to auto-detect the running version of Kubernetes, and map this to the corresponding CIS Benchmark version. For example, Kubernetes version 1.15 is mapped to CIS Benchmark version `cis-1.15` which is the benchmark version valid for Kubernetes 1.15.
|
||||
|
||||
kube-bench also attempts to identify the components running on the node, and uses this to determine which tests to run (for example, only running the master node tests if the node is running an API server).
|
||||
|
||||
The Kubernetes version can also be set with the `KUBE_BENCH_VERSION` environment variable.
|
||||
The value of `--version` takes precedence over the value of `KUBE_BENCH_VERSION`.
|
||||
### Specifying the benchmark or Kubernetes version
|
||||
|
||||
For example, run kube-bench against a master with version auto-detection:
|
||||
kube-bench uses the Kubernetes API, or access to the `kubectl` or `kubelet` executables to try to determine the Kubernetes version, and hence which benchmark to run. If you wish to override this, or if none of these methods are available, you can specify either the Kubernetes version or CIS Benchmark as a command line parameter.
|
||||
|
||||
You can specify a particular version of Kubernetes by setting the `--version` flag or with the `KUBE_BENCH_VERSION` environment variable. The value of `--version` takes precedence over the value of `KUBE_BENCH_VERSION`.
|
||||
|
||||
For example, run kube-bench using the tests for Kubernetes version 1.13:
|
||||
|
||||
```
|
||||
kube-bench master
|
||||
kube-bench --version 1.13
|
||||
```
|
||||
|
||||
Or run kube-bench against a worker node using the tests for Kubernetes version 1.13:
|
||||
|
||||
You can specify `--benchmark` to run a specific CIS Benchmark version:
|
||||
|
||||
```
|
||||
kube-bench node --version 1.13
|
||||
kube-bench --benchmark cis-1.5
|
||||
```
|
||||
|
||||
`kube-bench` will map the `--version` to the corresponding CIS Benchmark version as indicated by the mapping table above. For example, if you specify `--version 1.13`, this is mapped to CIS Benchmark version `cis-1.14`.
|
||||
**Note:** It is an error to specify both `--version` and `--benchmark` flags together
|
||||
|
||||
Alternatively, you can specify `--benchmark` to run a specific CIS Benchmark version:
|
||||
### Specifying Benchmark sections
|
||||
|
||||
```
|
||||
kube-bench node --benchmark cis-1.4
|
||||
```
|
||||
|
||||
If you want to target specific CIS Benchmark `target` (i.e master, node, etcd, etc...)
|
||||
If you want to run specific CIS Benchmark sections (i.e master, node, etcd, etc...)
|
||||
you can use the `run --targets` subcommand.
|
||||
|
||||
```
|
||||
kube-bench --benchmark cis-1.4 run --targets master,node
|
||||
kube-bench run --targets master,node
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```
|
||||
kube-bench --benchmark cis-1.5 run --targets master,node,etcd,policies
|
||||
kube-bench run --targets master,node,etcd,policies
|
||||
```
|
||||
|
||||
Check the contents of the benchmark directory under `cfg` to see which targets are available for that benchmark. Each file except `config.yaml` represents a target (also known as a `control` in other parts of this documentation).
|
||||
|
||||
The following table shows the valid targets based on the CIS Benchmark version.
|
||||
| CIS Benchmark | Targets |
|
||||
|---|---|
|
||||
| cis-1.3| master, node |
|
||||
| cis-1.4| master, node |
|
||||
| cis-1.5| master, controlplane, node, etcd, policies |
|
||||
| cis-1.6| master, controlplane, node, etcd, policies |
|
||||
| gke-1.0| master, controlplane, node, etcd, policies, managedservices |
|
||||
| eks-1.0| controlplane, node, policies, managedservices |
|
||||
|
||||
If no targets are specified, `kube-bench` will determine the appropriate targets based on the CIS Benchmark version.
|
||||
|
||||
`controls` for the various versions of CIS Benchmark can be found in directories
|
||||
with same name as the CIS Benchmark versions under `cfg/`, for example `cfg/cis-1.4`.
|
||||
|
||||
**Note:** **`It is an error to specify both --version and --benchmark flags together`**
|
||||
|
||||
If no targets are specified, `kube-bench` will determine the appropriate targets based on the CIS Benchmark version and the components detected on the node. The detection is done by verifying which components are running, as defined in the config files (see [Configuration](#configuration).
|
||||
### Running inside a container
|
||||
|
||||
You can avoid installing kube-bench on the host by running it inside a container using the host PID namespace and mounting the `/etc` and `/var` directories where the configuration and other files are located on the host so that kube-bench can check their existence and permissions.

|
||||
|
||||

|
||||
|
||||

|
||||
```
|
||||
|
||||
### Running in a Kubernetes cluster
|
||||
|
||||
You can run kube-bench inside a pod, but it will need access to the host's PID namespace in order to check the running processes, as well as access to some directories on the host where config files and other files are stored.
|
||||
|
||||
Master nodes are automatically detected by kube-bench and will run master checks when possible.
|
||||
The detection is done by verifying that mandatory components for master, as defined in the config files, are running (see [Configuration](#configuration)).
|
||||
|
||||
The supplied `job.yaml` file can be applied to run the tests as a job. For example:

```
|
||||
|
||||
You can still force to run specific master or node checks using respectively `job-master.yaml` and `job-node.yaml`.
|
||||
|
||||
To run the tests on the master node, the pod needs to be scheduled on that node. This involves setting a nodeSelector and tolerations in the pod spec.

To run tests on the master node, the pod needs to be scheduled on that node. This involves setting a nodeSelector and tolerations in the pod spec.
|
||||
|
||||
The default labels applied to master nodes has changed since Kubernetes 1.11, so if you are using an older version you may need to modify the nodeSelector and tolerations to run the job on the master node.

### Running on OpenShift
|
||||
|
||||
| OpenShift Hardening Guide | kube-bench config |
|
||||
|---|---|
|
||||
| ocp-3.10| rh-0.7 |
|
||||
| ocp-3.11| rh-0.7 |
|
||||
| ocp-4.* | Not supported |
|
||||
|
||||
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).
|
||||
|
||||
There is work in progress on a [CIS Red Hat OpenShift Container Platform Benchmark](https://workbench.cisecurity.org/benchmarks/5248) which we believe should cover OCP 4.* and we intend to add support in kube-bench when it's published.
|
||||
|
||||
### Running in a 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
|
||||
```
|
||||
|
||||
### Installing from a container
|
||||
|
||||
This command copies the kube-bench binary and configuration files to your host from the Docker container:
|
||||
** binaries compiled for linux-x86-64 only (so they won't run on macOS or Windows) **
|
||||
**binaries compiled for linux-x86-64 only (so they won't run on macOS or Windows)**

You can then run `./kube-bench [master|node]`.
|
||||
You can then run `./kube-bench`.
|
||||
|
||||
### Download and Install binaries
|
||||
|
||||
It is possible to manually install and run kube-bench release binaries. In order to do that, you must have access to your Kubernetes cluster nodes. Note that if you're using one of the managed Kubernetes services (e.g. EKS, AKS, GKE), you will not have access to the master nodes of your cluster and you can’t perform any tests on the master nodes.
|
||||
|
||||
First, log into one of the nodes using SSH.
|
||||
|
||||
Install kube-bench binary for your platform using the commands below. Note that there may be newer releases available. See [releases page](https://github.com/aquasecurity/kube-bench/releases).
|
||||
|
||||
Ubuntu/Debian:
|
||||
|
||||
```
|
||||
curl -L https://github.com/aquasecurity/kube-bench/releases/download/v0.3.1/kube-bench_0.3.1_linux_amd64.deb -o kube-bench_0.3.1_linux_amd64.deb
|
||||
|
||||
sudo apt install ./kube-bench_0.3.1_linux_amd64.deb -f
|
||||
```
|
||||
|
||||
RHEL:
|
||||
|
||||
```
|
||||
curl -L https://github.com/aquasecurity/kube-bench/releases/download/v0.3.1/kube-bench_0.3.1_linux_amd64.rpm -o kube-bench_0.3.1_linux_amd64.rpm
|
||||
|
||||
sudo yum install kube-bench_0.3.1_linux_amd64.rpm -y
|
||||
```
|
||||
|
||||
Alternatively, you can manually download and extract the kube-bench binary:
|
||||
|
||||
```
|
||||
curl -L https://github.com/aquasecurity/kube-bench/releases/download/v0.3.1/kube-bench_0.3.1_linux_amd64.tar.gz -o kube-bench_0.3.1_linux_amd64.tar.gz
|
||||
|
||||
tar -xvf kube-bench_0.3.1_linux_amd64.tar.gz
|
||||
```
|
||||
|
||||
You can then run kube-bench directly:
|
||||
```
|
||||
kube-bench
|
||||
```
|
||||
|
||||
If you manually downloaded the kube-bench binary (using curl command above), you have to specify the location of configuration directory and file. For example:
|
||||
```
|
||||
./kube-bench --config-dir `pwd`/cfg --config `pwd`/cfg/config.yaml
|
||||
```
|
||||
|
||||
See previous section on [Running kube-bench](#running-kube-bench) for further details on using the kube-bench binary.

## 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.

## 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).

Don't use fixed credentials within pods or container images, as they are at risk of exposure or abuse. Instead, use pod identities to automatically request access to other Azure resources using a central Azure AD identity solution.

Enable host-based encryption on Azure Kubernetes Service (AKS). With host-based encryption, the data stored on the VM host of your AKS agent nodes' VMs is encrypted at rest and flows encrypted to the Storage service. This means the temp disks are encrypted at rest with platform-managed keys. The cache of OS and data disks is encrypted at rest with either platform-managed keys or customer-managed keys depending on the encryption type set on those disks. See https://docs.microsoft.com/en-us/azure/aks/enable-host-encryption.

Azure Storage encrypts all data in a storage account at rest. By default, data is encrypted with Microsoft-managed keys. For additional control over encryption keys, you can supply customer-managed keys to use for encryption at rest for both the OS and data disks for your AKS clusters.

`env` is used to check if the value is present within a specified environment variable. The presence of `env` is treated as an OR operation, if both `flag` and `env` are supplied it will use either to attempt pass the check.

The command used for checking the environment variables of a process **is generated by default**.

If the command being generated is causing errors, you can override the command used by setting `auditEnv` on the check.

Similarly, if you don't want the environment checking command to be generated or run at all, specify `disableEnvTesting` as true on the check.

# Integrating kube-bench with AWS Security Hub
|
||||
|
||||
You can configure kube-bench with the `--asff` to send findings to AWS Security Hub. There are some additional steps required so that kube-bench has information and permissions to send these findings.
|
||||
|
||||
## Enable the AWS Security Hub integration
|
||||
|
||||
* You will need AWS Security Hub to be enabled in your account
|
||||
* In the Security Hub console, under Integrations, search for kube-bench
|
||||
|
||||
<p align="center">
|
||||
<img src="../images/kube-bench-security-hub.png">
|
||||
</p>
|
||||
|
||||
* Click on `Accept findings`. This gives information about the IAM permissions required to send findings to your Security Hub account. kube-bench runs within a pod on your EKS cluster, and will need to be associated with a Role that has these permissions.
|
||||
|
||||
## Configure permissions in an IAM Role
|
||||
|
||||
* Grant these permissions to the IAM Role that the kube-bench pod will be associated with. There are two options:
|
||||
* You can run the kube-bench pod under a specific [service account associated with an IAM role](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html) that has these permissions to write Security Hub findings.

||||
* Alternatively the pod can be granted permissions specified by the Role that your [EKS node group uses](https://docs.aws.amazon.com/eks/latest/userguide/managed-node-groups.html).
|
||||
|
||||
Here is an example IAM Policy that you can attach to your EKS node group's IAM Role:
|
||||
|
||||
```json
|
||||
{
|
||||
"Version": "2012-10-17",
|
||||
"Statement": [
|
||||
{
|
||||
"Effect": "Allow",
|
||||
"Action": "securityhub:BatchImportFindings",
|
||||
"Resource": [
|
||||
"arn:aws:securityhub:us-east-1::product/aqua-security/kube-bench"
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Modify the job configuration
|
||||
|
||||
* Modify the kube-bench Configmap in `job-eks-asff.yaml` to specify the AWS account, AWS region, and the EKS Cluster ARN.
|
||||
* In the same file, modify the image specifed in the Job to use the kube-bench image pushed to your ECR
|
||||
* [Optional] - If you have created a dedicated IAM role to be used with kube-bench as described above in [Configure permissions in an IAM Role](#configure-permissions-in-an-iam-role), you will need to add the IAM role arn to the kube-bench ServiceAccount in `job-eks-asff.yaml`.
|
||||
* Make sure that `job-eks-asff.yaml` specifies the container image you just pushed to your ECR registry.
|
||||
|
||||
You can now run kube-bench as a pod in your cluster: `kubectl apply -f job-eks-asff.yaml`
|
||||
|
||||
Findings will be generated for any kube-bench test that generates a `[FAIL]` or `[WARN]` output. If all tests pass, no findings will be generated. However, it's recommended that you consult the pod log output to check whether any findings were generated but could not be written to Security Hub.

== 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.
|
||||
|
||||
5.2.1 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 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.
