Authorization & Access Control

Type
Description
What is authorization?
Authorization is the process of determining what an authenticated user is allowed to do.
What is zero trust?
Zero trust is a security model that verifies every access request by identity and context instead of trusting a network location.
What is role-based access control (RBAC)?
Role-based access control (RBAC) grants permissions based on a user's role. Learn how RBAC works, its strengths, and its limits at scale.
What is attribute-based access control (ABAC)?
Attribute-based access control (ABAC) makes access decisions based on attributes of the user, resource, and context.
What is relationship-based access control (ReBAC)?
Relationship-based access control (ReBAC) grants access based on relationships between users and resources.
What is fine-grained authorization (FGA)?
Fine-grained authorization (FGA) controls access at the level of individual resources and actions. Learn how FGA works and why it's a growing discipline.
What is the principle of least privilege?
The principle of least privilege grants users and systems only the minimum access needed to do their job.
What is token-based authorization (JWT)?
Token-based authorization uses signed tokens like JWTs to convey a user's identity and permissions between systems.
