File Permissions for WordPress

Securing WordPress file permissions is crucial for maintaining its integrity and preventing unauthorized access. When initially setting up WordPress, it's recommended to grant write access to the webserver to facilitate installation and updates. The following permissions are appropriate:

• Root folder storing all WordPress content: 755
• wp-admin: 755
• wp-content: 755
• wp-includes: 755

After setup, it's essential to tighten file permissions for security purposes. As per hardening guidelines, all files except wp-content should be writable only by the user account. Wp-content must be writable by both the user account and www-data.

Tightened permissions:

• Root folder, wp-admin, wp-content, wp-includes: 755
• wp-content: 644 (rw-r--r--)

In case you require write access to wp-content later, consider these options:

• Temporarily switch to the www-data user account to grant write access.
• Grant group write access (775) to wp-content and add your user to the www-data group.
• Utilize Access Control Lists (ACLs) to grant your user write permissions.

Remember, the files in wp-content must always have rw permissions for www-data. By implementing appropriate file permissions, you can enhance the security of your WordPress website and protect against potential vulnerabilities.
