# 8.3.2 Implement Periodic Execution of File Integrity (Scored)

## Profile Applicability

- Level 2

## Description

Implement periodic file checking, in compliance with site policy.

## Rationale

Periodic file checking allows the system administrator to determine on a regular basis if critical files have been changed in an unauthorized fashion.

## Audit Procedure

### Using Command Line

Perform the following to determine if there is a `cron` job scheduled to run the aide check.

```bash
crontab -u root -l | grep aide
```

## Expected Result

```
0 5 * * * /usr/sbin/aide --check
```

## Remediation

### Using Command Line

Execute the following command:

```bash
crontab -u root -e
```

Add the following line to the crontab:

```bash
0 5 * * * /usr/sbin/aide --check
```

**Note:** The checking in this instance occurs every day at 5am. Alter the frequency and time of the checks in compliance with site policy.

## Default Value

By default, no periodic file integrity checking is configured.
