# 6.2.3.1 Ensure rsyslog service is enabled and active (Automated)

## Profile

- Level 1 - Server
- Level 1 - Workstation

## Description

Once the `rsyslog` package is installed, ensure that the service is enabled.

## Rationale

If the `rsyslog` service is not enabled to start on boot, the system will not capture logging events.

## Audit Procedure

### Command Line

- IF - `rsyslog` is being used for logging on the system:

Run the following command to verify `rsyslog.service` is enabled:

```bash
# systemctl is-enabled rsyslog
```

Run the following command to verify `rsyslog.service` is active:

```bash
# systemctl is-active rsyslog.service
```

## Expected Result

```
enabled
active
```

## Remediation

### Command Line

- IF - `rsyslog` is being used for logging on the system:

Run the following commands to unmask, enable, and start `rsyslog.service`:

```bash
# systemctl unmask rsyslog.service
# systemctl enable rsyslog.service
# systemctl start rsyslog.service
```

## Default Value

Enabled and active by default.
