# CIS 1.14 — Restrict update access to the CDI CR

## Profile Applicability

- Level 1

## Description

The `CDI` object is not namespaced and contains sensitive configuration data for the Containerized Data Importer.

## Rationale

Reduce at the minimum who can modify `CDI` resources.

## Impact

Workload owners don't normally need this feature.

## Audit Procedure

Check who can update the `cdi` resources:

```bash
$ oc adm policy who-can update cdi
```

## Remediation

Assign `update` access only to approved `cdi` objects in the cluster.

## Default Value

This permission is not granted by default.
