Role based access control is a strict and data restricting method that gives ideas of accessing the permission to the users based on their role & responsibilities in the organization. Most data centers and big organizations use this role based access control method for their data security to provide the user’s privileges with different levels of settings. For example, you are a web designer so the administrator and end users will assign to you the modifying and necessary files that you will need as well. This is a user privilege restricting method because it gives access to those users who verify their identities properly.
