# 2.1.16 Ensure rsync service is not installed (Automated)

## Description

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

## Rationale

The rsync service presents a security risk as it uses unencrypted protocols for communication. The rsync package should be removed to reduce the attack area of the system.

## Audit Procedure

### Command Line

Run the following command to verify rsync is not installed:

```bash
dpkg -s rsync | grep -E '(Status:|not installed)'
```

## Expected Result

```
dpkg-query: package 'rsync' is not installed and no information is available
```

## Remediation

### Command Line

Run the following command to remove rsync:

```bash
apt purge rsync
```

## Default Value

rsync is not installed on minimal server installations.
