Role-Based Access Control, or RBAC for short, is resource access-restricted based upon the user’s job title or role within an organization.

For example: you wouldn’t want John in accounting to have the same access privileges to your company’s infrastructure that Susie the engineer does.

RBAC makes it incredibly easy for a manager to designate what employees are granted permissions to perform certain operations on both a broad and finely-tuned, granular level.

The diagram below is a basic overview of RBAC:

RBAC_blog_diagram (2)RBAC Pros

  • Granular visibility
  • Simplifies network security management
  • Access to only what users need, when they need it

Why Use RBAC?

    • Reduce employee downtime due to access issues
    • More efficient provisioning
    • Implementation of Identity & Access Management policies (make sure only the right people have access to the correct systems)

2 Examples of RBAC

  • Providing access to developers or engineers vs admins or sales people
  • Choosing who has more or less access in an educational institution setting, such as students and faculty. Students would get access to student-designated WiFi and the student drives, faculty would get higher level staff-specific access, plus access to what students have.

 

Additional knowledge on Role-Based Access Control

 

3 Primary Rules for RBAC:

  1. Role assignment: A user can exercise a permission only if the subject has been assigned a role.
  2. Role-based authorization: A user’s active role must be authorized. With rule 1 above, this rule ensures that users can take on only roles for which they are authorized.
  3. Permission authorization: A user can make use of certain permissions only if the user is authorized to that specific permission, according to their role assignment in the role-based structure hierarchy. This rule specifies that 1 & 2 have been exercised.
