## Profile Applicability

- Level 1

## Description

Wireless networking is used when wired networks are unavailable. Ubuntu provides the nmcli interface which allows system administrators to configure and use wireless networks.

## Rationale

If wireless is not to be used, wireless devices can be disabled to reduce the potential attack surface.

## Audit Procedure

### Using Command Line

Perform the following to determine if wireless interfaces are active.

```bash
ifconfig -a
```

Validate that all interfaces using wireless are down.

## Expected Result

No active wireless interfaces should be present.

## Remediation

### Using Command Line

Use the following command to disable wireless:

```bash
nmcli nm wifi off
```

## Default Value

Wireless interfaces may be active by default if hardware is present.
