7a55d5d57c Issue: The initial command produces "root:root" as its output only when the file is present. However, if the file is missing, the command will still run successfully, though the desired output of "root:root" won't be obtained. (#1538)
Fix: To address this, we've modified the command to achieve the following:

Verify the existence of the file.

If the file is found, show the user and group ownership in the "username:groupname" format.

If the file is not found, display the message "File not found."

To accommodate this change, we've integrated the expected output "File not found" for instances where the file is absent. This adjustment ensures the successful execution of the test.

b942ed3f0b bugfix: false negative when audit_config is defined along with audit and config file not found (#1367)
Suppress the file not found error only when we have audit or auditEnv is defined and they have valid output captured.
As, we already have output from audit command. So we can proceed for our tests even though we didnt find config file.
file not found error: `failed to run: "/test/config.yaml", output: "/bin/sh: line 1: /test/config.yaml: No such file or directory\n", error: exit status 127`

## Testing locally with kind
Our makefile contains targets to test your current version of kube-bench inside a [Kind](https://kind.sigs.k8s.io/) cluster. This can be very handy if you don't want to run a real Kubernetes cluster for development purposes.
First, you'll need to create the cluster using `make kind-test-cluster` this will create a new cluster if it cannot be found on your machine. By default, the cluster is named `kube-bench` but you can change the name by using the environment variable `KIND_PROFILE`.
*If kind cannot be found on your system the target will try to install it using `go get`*
Next, you'll have to build the kube-bench docker image using `make build-docker`, then we will be able to push the docker image to the cluster using `make kind-push`.
Finally, we can use the `make kind-run` target to run the current version of kube-bench in the cluster and follow the logs of pods created. (Ctrl+C to exit)
Every time you want to test a change, you'll need to rebuild the docker image and push it to cluster before running it again. ( `make build-docker kind-push kind-run` )
To run the STIG tests locally execute the following: `make build-docker kind-push kind-run-stig`

kube-bench is a tool 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
![Kubernetes Bench for Security](/docs/images/output.png "Kubernetes Bench for Security")
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).
## CIS Scanning as part of Trivy and the Trivy Operator
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.
[Trivy](https://github.com/aquasecurity/trivy), the all in one cloud native security scanner, can be deployed as a [Kubernetes Operator](https://github.com/aquasecurity/trivy-operator) inside a cluster.
Both, the [Trivy CLI](https://github.com/aquasecurity/trivy), and the [Trivy Operator](https://github.com/aquasecurity/trivy-operator) support CIS Kubernetes Benchmark scanning among several other features.
1. It is impossible to inspect the master nodes of managed clusters, e.g. GKE, EKS, AKS and ACK, 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.

## CIS Kubernetes Benchmark support
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 |
|---|---|---|
| [1.5.1](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 |
| [ACK 1.0.0](https://workbench.cisecurity.org/benchmarks/6467) | ack-1.0 | ACK |
| 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). 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.
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).
### Specifying the benchmark or Kubernetes version
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 --version 1.13
```
You can specify `--benchmark` to run a specific CIS Benchmark version:
```
kube-bench --benchmark cis-1.5
```
**Note:** It is an error to specify both `--version` and `--benchmark` flags together
### Specifying Benchmark sections
If you want to run specific CIS Benchmark sections (i.e master, node, etcd, etc...)
you can use the `run --targets` subcommand.
```
kube-bench run --targets master,node
```
or
```
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-1.5| 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 |
| ack-1.0| master, controlplane, node, etcd, policies, managedservices |
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.
```
docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -t aquasec/kube-bench:latest --version 1.13
```
> Note: the tests require either the kubelet or kubectl binary in the path in order to auto-detect the Kubernetes version. You can pass `-v $(which kubectl):/usr/local/mount-from-host/bin/kubectl` to resolve this. You will also need to pass in kubeconfig credentials. For example:
```
docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -v $(which kubectl):/usr/local/mount-from-host/bin/kubectl -v ~/.kube:/.kube -e KUBECONFIG=/.kube/config -t aquasec/kube-bench:latest
```
You can use your own configs by mounting them over the default ones in `/opt/kube-bench/cfg/`
```
docker run --pid=host -v /etc:/etc:ro -v /var:/var:ro -t -v path/to/my-config.yaml:/opt/kube-bench/cfg/config.yam -v $(which kubectl):/usr/local/mount-from-host/bin/kubectl -v ~/.kube:/.kube -e KUBECONFIG=/.kube/config aquasec/kube-bench:latest
```
### Running in a Kubernetes cluster
## Quick start
There are multiple ways to run kube-bench.
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.
The supplied `job.yaml` file can be applied to run the tests as a job. For example:
The supplied `job.yaml` [file](job.yaml) can be applied to run the tests as a job. For example:
```bash
$ kubectl apply -f job.yaml

[INFO] 1.1 API Server
...
```
For more information and different ways to run kube-bench see [documentation](docs/running.md)
### Please Note
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.

To report issues in the Benchmark itself (for example, tests that you believe are inappropriate), please join the [CIS community](https://cisecurity.org).
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 in an AKS cluster
1. There is not a one-to-one mapping between releases of Kubernetes and releases of the CIS benchmark. See [CIS Kubernetes Benchmark support](docs/platforms.md#cis-kubernetes-benchmark-support) to see which releases of Kubernetes are covered by different releases of the benchmark.
1. Create an AKS cluster(e.g. 1.13.7) with RBAC enabled, otherwise there would be 4 failures
1. Use the [kubectl-enter plugin](https://github.com/kvaps/kubectl-enter) to shell into a node
`
kubectl-enter {node-name}
`
or ssh to one agent node
could open nsg 22 port and assign a public ip for one agent node (only for testing purpose)
By default, kube-bench will determine the test set to run based on the Kubernetes version running on the machine.
- see the following documentation on [Running kube-bench](docs/running.md#running-kube-bench) for more details.
1. Run CIS benchmark to view results:
```
docker run --rm -v `pwd`:/host aquasec/kube-bench:latest install
./kube-bench
```
kube-bench cannot be run on AKS master nodes
### Running in an EKS cluster
There is a `job-eks.yaml` file for running the kube-bench node checks on an EKS cluster. The significant difference on EKS is that it's not possible to schedule jobs onto the master node, so master checks can't be performed
1. To create an EKS Cluster refer to [Getting Started with Amazon EKS](https://docs.aws.amazon.com/eks/latest/userguide/getting-started.html) in the *Amazon EKS User Guide*
- Information on configuring `eksctl`, `kubectl` and the AWS CLI is within
2. Create an [Amazon Elastic Container Registry (ECR)](https://docs.aws.amazon.com/AmazonECR/latest/userguide/what-is-ecr.html) repository to host the kube-bench container image
```
aws ecr create-repository --repository-name k8s/kube-bench --image-tag-mutability MUTABLE
```
3. Download, build and push the kube-bench container image to your ECR repo
```
git clone https://github.com/aquasecurity/kube-bench.git
cd kube-bench
aws ecr get-login-password --region <AWS_REGION> | docker login --username AWS --password-stdin <AWS_ACCT_NUMBER>.dkr.ecr.<AWS_REGION>.amazonaws.com
docker build -t k8s/kube-bench .
docker tag k8s/kube-bench:latest <AWS_ACCT_NUMBER>.dkr.ecr.<AWS_REGION>.amazonaws.com/k8s/kube-bench:latest
docker push <AWS_ACCT_NUMBER>.dkr.ecr.<AWS_REGION>.amazonaws.com/k8s/kube-bench:latest
```
4. Copy the URI of your pushed image, the URI format is like this: `<AWS_ACCT_NUMBER>.dkr.ecr.<AWS_REGION>.amazonaws.com/k8s/kube-bench:latest`
5. Replace the `image` value in `job-eks.yaml` with the URI from Step 4
6. Run the kube-bench job on a Pod in your Cluster: `kubectl apply -f job-eks.yaml`
7. Find the Pod that was created, it *should* be in the `default` namespace: `kubectl get pods --all-namespaces`
8. Retrieve the value of this Pod and output the report, note the Pod name will vary: `kubectl logs kube-bench-<value>`
- You can save the report for later reference: `kubectl logs kube-bench-<value> > kube-bench-report.txt`
#### Report kube-bench findings to AWS Security Hub
You can configure kube-bench with the `--asff` option to send findings to AWS Security Hub for any benchmark tests that fail or that generate a warning. See [this page][kube-bench-aws-security-hub] for more information on how to enable the kube-bench integration with AWS Security Hub.
### 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
```
### Running in a ACK cluster
| CIS Benchmark | Targets |
|---|---|
| ack-1.0| master, controlplane, node, etcd, policies, managedservices |
kube-bench includes benchmarks for Alibaba Cloud Container Service For Kubernetes (ACK).
To run this you will need to specify `--benchmark ack-1.0` when you run the `kube-bench` command.
To run the benchmark as a job in your ACK cluster apply the included `job-ack.yaml`.
```
kubectl apply -f job-ack.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)**
```
docker run --rm -v `pwd`:/host aquasec/kube-bench:latest install
```
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, ACK), you will not have access to the master nodes of your cluster and you cant 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.
### Installing from sources
If Go is installed on the target machines, you can simply clone this repository and run as follows (assuming your [`GOPATH` is set](https://github.com/golang/go/wiki/GOPATH)):
```shell
go get github.com/aquasecurity/kube-bench
cd $GOPATH/src/github.com/aquasecurity/kube-bench
go build -o kube-bench .
# See all supported options
./kube-bench --help
# Run all checks
./kube-bench
```
## Output
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. This is to highlight tests that appear to be incompletely defined.
## Configuration
Kubernetes configuration and binary file locations and names can vary from installation to installation, so these are configurable in the `cfg/config.yaml` file.
Any settings in the version-specific config file `cfg/<version>/config.yaml` take precedence over settings in the main `cfg/config.yaml` file.
You can read more about `kube-bench` configuration in our [documentation](docs/README.md#configuration-and-variables).
## 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).
### Omitting checks
If you decide that a recommendation is not appropriate for your environment, you can choose to omit it by editing the test YAML file to give it the check type `skip` as in this example:
```yaml
checks:
- id: 2.1.1
text: "Ensure that the --allow-privileged argument is set to false (Scored)"
type: "skip"
scored: true
```
No tests will be run for this check and the output will be marked [INFO].
## Contributing
Kindly read [Contributing](CONTRIBUTING.md) before contributing.
We welcome PRs and issue reports.
## Roadmap
Going forward we plan to release updates to kube-bench to add support for new releases of the CIS Benchmark. Note that these are not released as frequently as Kubernetes releases.
We welcome PRs and issue reports.
## Testing locally with kind
Our makefile contains targets to test your current version of kube-bench inside a [Kind](https://kind.sigs.k8s.io/) cluster. This can be very handy if you don't want to run a real Kubernetes cluster for development purposes.
First, you'll need to create the cluster using `make kind-test-cluster` this will create a new cluster if it cannot be found on your machine. By default, the cluster is named `kube-bench` but you can change the name by using the environment variable `KIND_PROFILE`.
*If kind cannot be found on your system the target will try to install it using `go get`*
Next, you'll have to build the kube-bench docker image using `make build-docker`, then we will be able to push the docker image to the cluster using `make kind-push`.
Finally, we can use the `make kind-run` target to run the current version of kube-bench in the cluster and follow the logs of pods created. (Ctrl+C to exit)
Every time you want to test a change, you'll need to rebuild the docker image and push it to cluster before running it again. ( `make build-docker kind-push kind-run` )

Azure Container Registry
If you use Azure Container Registry (ACR) as your container image store, you need to grant
permissions to the service principal for your AKS cluster to read and pull images. Currently,
the recommended configuration is to use the az aks create or az aks update command to
integrate with a registry and assign the appropriate role for the service principal. For
detailed steps, see Authenticate with Azure Container Registry from Azure Kubernetes
Service.
To avoid needing an Owner or Azure account administrator role, you can configure a
service principal manually or use an existing service principal to authenticate ACR from
AKS. For more information, see ACR authentication with service principals or Authenticate

Azure Active Directory integration
The security of AKS clusters can be enhanced with the integration of Azure Active Directory
(AD). Built on decades of enterprise identity management, Azure AD is a multi-tenant,
cloud-based directory, and identity management service that combines core directory
services, application access management, and identity protection. With Azure AD, you can
integrate on-premises identities into AKS clusters to provide a single source for account
management and security.
Azure Active Directory integration with AKS clusters
With Azure AD-integrated AKS clusters, you can grant users or groups access to Kubernetes
resources within a namespace or across the cluster. To obtain a kubectl configuration
context, a user can run the az aks get-credentials command. When a user then interacts
with the AKS cluster with kubectl, they're prompted to sign in with their Azure AD
credentials. This approach provides a single source for user account management and
password credentials. The user can only access the resources as defined by the cluster
administrator.
Azure AD authentication is provided to AKS clusters with OpenID Connect. OpenID Connect
is an identity layer built on top of the OAuth 2.0 protocol. For more information on OpenID
Connect, see the Open ID connect documentation. From inside of the Kubernetes cluster,
Webhook Token Authentication is used to verify authentication tokens. Webhook token
authentication is configured and managed as part of the AKS cluster.

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.

Implement Azure Policy to define the AppArmor profile used by containers. See https://docs.microsoft.com/en-us/azure/aks/use-pod-security-on-azure-policy#additional-optional-policies.
Review the use of capabilities in applications running on your cluster. Where a namespace
contains applications 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.

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:

- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).

text: "Ensure that the audit policy covers key security concerns (Manual)"
type: "manual"
remediation: |
Review the audit policy provided for the cluster and ensure that it covers
at least the following areas,
- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).

- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).

- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).

- Access to Secrets managed by the cluster. Care should be taken to only
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
order to avoid risk of logging sensitive data.
- Modification of Pod and Deployment objects.
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
For most requests, minimally logging at the Metadata level is recommended
(the most basic level of logging).
