4.3 Identity and Access Management (IAM) Concepts Explained

Key Concepts

Identity and Access Management (IAM) involves the processes and technologies used to manage digital identities and control access to resources. Key concepts include Authentication, Authorization, Single Sign-On (SSO), and Role-Based Access Control (RBAC).

Authentication

Authentication is the process of verifying the identity of a user or system. It ensures that the entity attempting to access a resource is who they claim to be. Common authentication methods include passwords, multi-factor authentication (MFA), and biometrics.

Example: When logging into a corporate email system, a user must enter their username and password. Additionally, they may be prompted to enter a one-time code sent to their mobile device, which is an example of multi-factor authentication.

Authorization

Authorization is the process of determining what actions or resources a user or system is allowed to access after they have been authenticated. It involves defining and enforcing access policies based on roles, permissions, and security policies.

Example: After a user successfully authenticates to a file server, the system checks their role (e.g., administrator, regular user) to determine which files and folders they are authorized to access and modify.

Single Sign-On (SSO)

Single Sign-On (SSO) allows users to authenticate once and gain access to multiple applications or systems without needing to re-enter credentials. SSO simplifies the user experience and reduces the risk of password fatigue and reuse.

Example: A university implements SSO for its online portal, allowing students to log in once with their university credentials and access various services such as email, course registration, and library resources without needing to log in separately for each service.

Role-Based Access Control (RBAC)

Role-Based Access Control (RBAC) is a method of regulating access to resources based on the roles of individual users within an organization. Roles are defined based on job functions, and permissions are assigned to roles rather than individual users.

Example: In a hospital, doctors, nurses, and administrative staff have different roles. RBAC ensures that doctors have access to patient medical records, while nurses can view but not modify certain records, and administrative staff have access to billing information but not medical records.

Conclusion

Identity and Access Management (IAM) is essential for ensuring that only authorized users can access sensitive resources. By understanding and implementing concepts such as Authentication, Authorization, Single Sign-On (SSO), and Role-Based Access Control (RBAC), organizations can enhance security, streamline access, and improve user experience.
