Lecture 70 :- AuthN & AuthZ - Class 1 [HD]

It seems like you're referring to "Authentication" and "Authorization" in the context of Class 1 security. Let me break down these concepts for you:

Authentication (AuthN): Authentication is the process of verifying the identity of a user, system, or entity. It ensures that the entity claiming an identity is, in fact, who they say they are. The primary goal of authentication is to prevent unauthorized access to a system or resource. There are several methods of authentication, including:

1. Username and Password: The most common method where a user provides a unique username and a corresponding secret password.
2. Biometric Authentication: Using physiological characteristics like fingerprints, facial recognition, or iris scans to verify identity.
3. Multi-Factor Authentication (MFA): A combination of two or more authentication methods (e.g., password and SMS code) for added security.
4. Single Sign-On (SSO): Allows users to use one set of credentials to access multiple applications or systems.
5. Certificate-Based Authentication: Utilizes digital certificates to validate the identity of users or systems.

Authorization (AuthZ): Authorization is the process of determining what actions or resources a user or entity is allowed to access after successful authentication. It involves checking the permissions and privileges associated with the authenticated identity to ensure they have the appropriate rights to perform certain actions or access specific resources. Authorization is essential for maintaining the principle of least privilege, where users are only granted the minimum access necessary to perform their tasks.

Class 1 Security: In the context of security classifications, Class 1 generally refers to the lowest level of security. It indicates basic or minimal security measures, often suitable for non-sensitive or public information. Class 1 security might involve simple authentication methods like username and password, but it might lack more advanced security features like encryption or robust access control.

It's worth noting that the term "Class 1" can be specific to certain security frameworks or organizations, and the exact meaning might vary in different contexts. Security measures are typically classified into multiple levels or classes to help tailor security practices to the sensitivity of the data and the risk associated with its exposure.
