# Uninstall dnsmasq Package
 
## Description{% #description %}

dnsmasq is a lightweight tool that provides DNS caching, DNS forwarding and DHCP (Dynamic Host Configuration Protocol) services.

The `dnsmasq` package can be removed with the following command:

```

$ apt-get remove dnsmasq
```

## Rationale{% #rationale %}

Unless a system is specifically designated to act as a DNS caching, DNS forwarding and/or DHCP server, it is recommended that the package be removed to reduce the potential attack surface.

## Remediation{% #remediation %}

### Shell script{% #shell-script %}

The following script can be run on the host to remediate the issue.

```bash
#!/bin/bash

# CAUTION: This remediation script will remove dnsmasq
# from the system, and may remove any packages
# that depend on dnsmasq. Execute this
# remediation AFTER testing on a non-production
# system!


DEBIAN_FRONTEND=noninteractive apt-get remove -y "dnsmasq"
```

### Ansible playbook{% #ansible-playbook %}

The following playbook can be run with Ansible to remediate the issue.
