# 5.1.2.1 Ensure rsyslog is installed (Automated)

## Profile

- **Level:** 1 - Server
- **Level:** 1 - Workstation
- **Assessment Status:** Automated

## Description

The `rsyslog` software is recommended in environments where `journald` does not meet operation requirements.

## Rationale

The security enhancements of `rsyslog` such as connection-oriented (i.e. TCP) transmission of logs, the option to log to database formats, and the encryption of log data en route to a central logging server) justify installing and configuring the package.

## Audit Procedure

### Command Line

Run the following command to verify `rsyslog` is installed:

```bash
dpkg-query -s rsyslog &>/dev/null && echo "rsyslog is installed"
```

## Expected Result

```
rsyslog is installed
```

## Remediation

### Command Line

Run the following command to install `rsyslog`:

```bash
apt install rsyslog
```

## Default Value

rsyslog is not installed by default on Ubuntu 18.04.
