# Verify Permissions on passwd File
 
## Description{% #description %}

To properly set the permissions of `/etc/passwd`, run the command:

```
$ sudo chmod 0644 /etc/passwd
```

## Rationale{% #rationale %}

If the `/etc/passwd` file is writable by a group-owner or the world the risk of its compromise is increased. The file contains the list of accounts on the system and associated information, and protection of this file is critical for system security.

## Remediation{% #remediation %}

### Shell script{% #shell-script %}

The following script can be run on the host to remediate the issue.

```bash
#!/bin/bash

chmod u-xs,g-xws,o-xwt /etc/passwd
```

### Ansible playbook{% #ansible-playbook %}

The following playbook can be run with Ansible to remediate the issue.
