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.

    Authentication & Access Control

    This section explores authentication and access control, highlighting methods and models essential for securing access to systems.

    Learning Practice

  • 4.1

    What Is Authentication?

    Authentication is the process of verifying the identity of a user, device, or system.

    Learning Practice

  • 4.2

    What Is Authorization?

    Authorization is the process of determining what actions a user is allowed to perform after their identity has been authenticated.

    Learning Practice

  • 4.3

    Multi-Factor Authentication (Mfa)

    Multi-Factor Authentication (MFA) enhances security by requiring users to provide two or more forms of verification to access accounts.

    Learning Practice

  • 4.4

    Access Control Models

    Access control models manage permissions and entitlements for users and systems, ensuring secure resource access based on defined criteria.

    Learning Practice

  • 4.4.1

    Role-Based Access Control (Rbac)

    Role-Based Access Control (RBAC) restricts system access based on user roles.

    Learning Practice

  • 4.4.2

    Discretionary Access Control (Dac)

    Discretionary Access Control (DAC) is a flexible access control method that allows data owners to define who can access their resources.

    Learning Practice

  • 4.4.3

    Mandatory Access Control (Mac)

    Mandatory Access Control (MAC) is an access control model where access policies are enforced by the system based on predefined rules rather than user discretion.

    Learning Practice

  • 4.4.4

    Attribute-Based Access Control (Abac)

    Attribute-Based Access Control (ABAC) uses attributes like time, location, and device to determine access permissions, offering dynamic and granular access control compared to other methods.

    Learning Practice

  • 4.5

    Access Control Lists (Acls)

    Access Control Lists (ACLs) define user permissions for accessing resources within a system, enabling effective management of security protocols.

    Learning Practice

  • 4.6

    Identity And Access Management (Iam)

    This section covers the framework of Identity and Access Management (IAM), focusing on ensuring the right individuals access the right resources at the right time.

    Learning Practice

  • 4.7

    Common Threats & Mistakes

    This section highlights common threats and mistakes in authentication and access control, emphasizing the impact of weak security practices.

    Learning Practice

  • 4.8

    Real-World Case Study
