# 8.1.1.1 Configure Audit Log Storage Size (Not Scored)

## Profile Applicability

- Level 2

## Description

Configure the maximum size of the audit log file. Once the log reaches the maximum size, it will be rotated and a new log file will be started.

## Rationale

It is important that an appropriate size is determined for log files so that they do not impact the system and audit data is not lost.

## Audit Procedure

### Using Command Line

Perform the following to determine the maximum size of the audit log files.

```bash
grep max_log_file /etc/audit/auditd.conf
```

## Expected Result

```
max_log_file = <MB>
```

## Remediation

### Using Command Line

Set the `max_log_file` parameter in `/etc/audit/auditd.conf`:

```bash
max_log_file = <MB>
```

**Note:** `MB` is the number of MegaBytes the file can be.

## Default Value

By default, auditd will max out the log files at 5MB and retain only 4 copies of them.
