# Verify Permissions of Files in /var/log/gdm
 
## Description{% #description %}

To properly set the permissions of `/var/log/gdm/*`, run the command:

```gdscript3
$ sudo chmod 0660 /var/log/gdm/*
```

## Rationale{% #rationale %}

The `/var/log/gdm` directory contains information about the GDM daemon and should only be accessed by authorized personnel.

## Remediation{% #remediation %}

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

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

```bash
#!/bin/bash

find -P /var/log/gdm/  -perm /u+xs,g+xs,o+xwrt  -type f -regextype posix-extended -regex '.*' -exec chmod u-xs,g-xs,o-xwrt {} \;
```

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

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

```gdscript3
- name: Find /var/log/gdm/ file(s) recursively
  ansible.builtin.command: find -P /var/log/gdm/  -perm /u+xs,g+xs,o+xwrt  -type f
