# 6.16 Ensure rsync service is not enabled (Not Scored)

## Profile Applicability

- Level 1

## Description

The `rsyncd` service can be used to synchronize files between systems over network links.

## Rationale

The `rsyncd` service presents a security risk as it uses unencrypted protocols for communication.

## Audit Procedure

### Using Command Line

Ensure that the `rsync` service is not enabled:

```bash
grep ^RSYNC_ENABLE /etc/default/rsync
```

## Expected Result

```
RSYNC_ENABLE=false
```

## Remediation

### Using Command Line

Set `RSYNC_ENABLE` to `false` in `/etc/default/rsync`:

```bash
sed -i 's/^RSYNC_ENABLE=.*/RSYNC_ENABLE=false/' /etc/default/rsync
```

## Default Value

rsync is disabled by default on Ubuntu 12.04 LTS Server (RSYNC_ENABLE=false).
