3.15 Security in Identity and Access Management (IAM) Explained
Key Concepts
Security in Identity and Access Management (IAM) involves managing and securing user identities and their access to resources. Key concepts include authentication, authorization, and identity federation.
Authentication
Authentication is the process of verifying the identity of a user or system. It ensures that the user is who they claim to be. Common authentication methods include passwords, multi-factor authentication (MFA), and biometrics.
Example: A user logs into a corporate network using a password and a one-time code sent to their mobile device. This combination of password and one-time code provides strong authentication, ensuring that only the legitimate user can access the network.
Authorization
Authorization is the process of granting or denying access to resources based on the authenticated user's identity and permissions. It ensures that users can only access the resources they are allowed to.
Example: After authenticating, a user is granted access to specific files and applications based on their role within the organization. An employee in the finance department can access financial reports, while an employee in the marketing department cannot.
Identity Federation
Identity Federation allows users to use a single set of credentials to access multiple systems and services across different organizations. It simplifies the authentication process and enhances security by centralizing identity management.
Example: A university uses identity federation to allow its students to access online resources from multiple academic institutions using their university credentials. This eliminates the need for students to create and manage separate accounts for each institution.
Conclusion
Security in Identity and Access Management (IAM) is essential for protecting resources and ensuring that only authorized users can access them. By implementing robust authentication, precise authorization, and seamless identity federation, organizations can enhance security and streamline access management.
