Understanding Authentication and Authorization: Key Concepts Explained

Learn the essential differences between authentication and authorization, and best practices for secure access control.

520 views

Authentication verifies the identity of a user, commonly using usernames and passwords. Authorization determines what an authenticated user is allowed to do. Steps include: setting up a strong password policy, using multi-factor authentication (MFA), and employing role-based access control (RBAC). Implement OAuth or JWT for token-based authentication systems. Regularly review and update permissions to maintain security.

FAQs & Answers

  1. What is the difference between authentication and authorization? Authentication verifies who you are, while authorization determines what you can do.
  2. Why is multi-factor authentication important? MFA adds an extra layer of security, reducing the risk of unauthorized access.
  3. What is role-based access control? RBAC restricts system access to authorized users based on their role within the organization.
  4. How do OAuth and JWT work? OAuth is an authorization framework, while JWT is a token standard used within OAuth to securely transmit identification information.
