# 4.2.4 Ensure permissions on all logfiles are configured (Scored)

## Profile Applicability

- Level 1 - Server
- Level 1 - Workstation

## Description

Log files stored in `/var/log/` contain logged information from many services on the system, or on log hosts others as well.

## Rationale

It is important to ensure that log files have the correct permissions to ensure that sensitive data is archived and protected.

## Audit Procedure

Run the following command and verify that other has no permissions on any files and group does not have write or execute permissions on any files:

```bash
find /var/log -type f -ls
```

## Expected Result

All log files should have permissions of 640 or more restrictive. No files should have world-readable, world-writable, or world-executable permissions. Group should not have write or execute permissions.

## Remediation

Run the following command to set permissions on all existing log files:

```bash
chmod -R g-wx,o-rwx /var/log/*
```

**Notes:** You may also need to change the configuration for your logging software or services for any logs that had incorrect permissions.

## Default Value

Permissions may vary depending on the logging service and log file.
