# How to enable CIS

```{note}
On Focal (and later releases), CIS was
[replaced by USG](https://ubuntu.com/security/certifications/docs/usg),
therefore, just change `cis` to `usg` when running the enable command on those
releases.
```

To access the CIS tooling, first enable the software repository as follows:

```console
$ sudo pro enable cis
```

You should see output like the following, indicating that the CIS package has
been installed:

```
Installing CIS Audit packages
CIS Audit enabled
Visit https://security-certs.docs.ubuntu.com/en/cis to learn how to use CIS
```

Once the feature is enabled please
[follow the documentation](https://ubuntu.com/security/certifications/docs/cis)
for the CIS tooling, to run the provided hardening audit scripts.
