Authentication & Access Control
This chapter covers the essential concepts of authentication and access control, highlighting the importance of distinguishing between the two. It explores various authentication methods, emphasizes the significance of multi-factor authentication (MFA), and discusses different access control models such as Role-Based Access Control (RBAC) and Access Control Lists (ACLs). Additionally, it underscores the critical role of Identity and Access Management (IAM) in maintaining secure access to resources within organizations.

- Access controls like RBAC, DAC, MAC help manage user privileges effectively.
- IAM systems are essential for large organizations to manage identities and permissions securely.
Key Concepts
- -- Authentication
- The process of verifying the identity of a user, device, or system.
- -- Authorization
- The process of determining the level of access granted to a user after authentication.
- -- MultiFactor Authentication (MFA)
- A security process that requires two or more verification factors to gain access to a resource.
- -- RoleBased Access Control (RBAC)
- An access control model where access rights are assigned based on a user's role.
- -- Access Control Lists (ACLs)
- Lists that specify what actions users or systems can perform on various resources.
- -- Identity and Access Management (IAM)
- A framework of policies and technologies that ensure the right individuals access the right resources at the right time.
