Identity and Access Management (IAM) is a framework of policies, processes, and technologies that ensures the right individuals have the appropriate access to technology resources at the right time and for the right reasons. IAM is a critical part of cybersecurity because it controls who can access what, and helps prevent unauthorized access to sensitive data and systems.
🔐 Key Functions of IAM:
-
Identity Management
-
Creating, managing, and deleting user identities (e.g., employees, customers, partners).
-
-
Authentication
-
Verifying a user’s identity using passwords, biometrics, multi-factor authentication (MFA), etc.
-
-
Authorization
-
Granting or denying access to systems and data based on a user’s identity and role.
-
-
Access Control
-
Ensuring users can access only what they are allowed to, based on roles, rules, or policies.
-
-
Single Sign-On (SSO)
-
Allowing users to log in once and access multiple applications without re-entering credentials.
-
-
Audit and Compliance
-
Keeping records of who accessed what, when, and how — critical for security audits and legal compliance.
