# Usage of permissive file permission ('other')

## Overview

* **Rule ID**: `java_lang_file_permission_others`
* **Applicable Languages**: Java
* **Weakness ID**: CWE-732

## Description

Granting excessively permissive file permissions, particularly to the 'other' category, poses a significant security risk by potentially exposing sensitive information to unauthorized users.

## Remediation Guidelines

* **Ensur**e file permissions are set as strictly as required. Prioritize assigning permissions to 'groups' rather than 'others' to mitigate the risk of unauthorized access

  ```java
  permissions.add(PosixFilePermission.GROUP_WRITE)
  ```
