When we talk about WordPress security, setting correct WordPress file permissions always comes up in the conversation as a security measure.

In the most basic terms, file permissions decide who has permission to do what to your WP files.

Incorrect file & folder permissions can lead to security risks and cause loading errors to your website. Therefore, it is extremely crucial that you make sure your WP website files and folders have correct and secure permissions to them.

If you have no clue how to do this, we are here to help you out. Read through.

WordPress File Permission?

WordPress file permissions are the permissions given to a certain user to maintain the website, dissected as permission to read, write, and execute.

When permissions are set properly, it adds a security layer by preventing unauthorized access to your WordPress files and folders.

However, if the permissions are not set properly, it can result in security breaches and server errors. These errors may vary from 403 forbidden errors to a white screen, etc.

All the actions (read, write, and execute) have a number to denote the said action. The list of the privilege permissions using numbers can be given as:

  • No access(0)
  • Execute(1)
  • Write(2)
  • Write and Execute(3)
  • Read(4)
  • Execute and Read(5)
  • Read and Write(6)
  • Read, Write, and Execute(7)
