# CIS Red Hat OpenShift Container Platform Benchmark v1.6.0 - Control 5.2.9

## Profile Applicability

- **Level:** 2

## Description

Do not generally permit containers with capabilities.

## Rationale

Containers run with a default set of capabilities as assigned by the Container Runtime. Capabilities are parts of the rights generally granted on a Linux system to the root user.

In many cases applications running in containers do not require any capabilities to operate, so from the perspective of the principal of least privilege use of capabilities should be minimized.

## Impact

Pods with containers which require capabilities to operate will not be permitted.

## Audit Procedure

Use the following command to list SCCs that drop all capabilities from containers:

```bash
oc get scc -A -o json | jq '.items[] |
select(.requiredDropCapabilities[]?|any(. == "ALL"; .)) | .metadata.name'
```

Verify at least one SCC is returned.

## Remediation

Review the use of capabilities in applications running on your cluster. Where a namespace contains applications which do not require any Linux capabilities to operate, consider adding a SCC which forbids the admission of containers which do not drop all capabilities.

## Default Value

By default, OpenShift includes three SCCs that drop all container capabilities:

```
"hostnetwork-v2"
"nonroot-v2"
"restricted-v2"
```
