Role-based access control in GraphQL - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Role-based Access Control (RBAC)?

RBAC is a method to restrict system access to authorized users based on their roles. Each role has specific permissions that define what actions users can perform.

beginner

In RBAC, what is a 'role'?

A role is a named collection of permissions that define what actions a user assigned to that role can perform in the system.

How does RBAC improve security in applications?

RBAC limits access by assigning users only the permissions needed for their role, reducing the risk of unauthorized actions and simplifying permission management.

beginner

What is the difference between a user and a role in RBAC?

A user is an individual who accesses the system, while a role is a set of permissions. Users are assigned roles to gain the permissions associated with those roles.

Give an example of how RBAC might be used in a GraphQL API.

In a GraphQL API, RBAC can restrict queries and mutations based on user roles. For example, only users with the 'admin' role can perform mutations that delete data.

What does RBAC stand for?

A Read-Back Access Control

B Random Binary Access Code

C Role-based Access Control

D Role Binding Access Code

RBAC stands for Role-based Access Control, a method to manage user permissions based on roles.

In RBAC, who gets assigned roles?

A Permissions

B Servers

C Databases

D Users

Users are assigned roles which grant them specific permissions.

Which of these is a benefit of RBAC?

A Simplifies permission management

B Allows all users full access

C Removes the need for passwords

D Automatically creates roles

RBAC simplifies permission management by grouping permissions into roles.

In a GraphQL API, how can RBAC be applied?

A By disabling the API for some users

B By restricting queries and mutations based on user roles

C By encrypting all data automatically

D By changing the schema dynamically

RBAC restricts access to queries and mutations depending on the user's role.

Which is NOT part of RBAC?

A IP addresses

B Users

C Permissions

D Roles

IP addresses are not part of RBAC; RBAC focuses on users, roles, and permissions.

Explain how Role-based Access Control works in a system.

Think about how users get permissions through roles.

Describe how you would implement RBAC in a GraphQL API.

Consider how to control who can run which GraphQL operations.
