Identity and Access Management (IAM)

Identity and Access Management (IAM) is a framework that ensures the right people, machines, and software components have access to the right resources at the right time, while preventing unauthorized access. It involves managing digital identities, authenticating users, and authorizing access based on roles and permissions. It focuses on controlling access to computer systems, cloud applications, networks, and assets based on each user or device's digital identity.

Key Components of IAM

  1. User Identity Management: This involves creating, managing, and deactivating user accounts. It includes processes for user registration, profile management, and authentication methods such as passwords, biometrics, or multi-factor authentication.
  2. Access Control: IAM establishes who can access what resources and under which conditions. It involves defining roles and permissions, often using Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC), to grant and limit access based on job functions or user attributes.
  3. Authentication and Authorization: Authentication verifies the identity of a user (e.g., via passwords or tokens), while authorization ensures that a user has permission to access specific resources based on their roles or other policies.
  4. Audit and Monitoring: IAM systems monitor user activities and access patterns to detect potential security breaches or policy violations. Regular auditing helps ensure compliance with regulations and internal security standards.

Examples of IAM Technologies

  • Single Sign-On (SSO):Allows users to access multiple applications with a single set of credentials. 
  • Multi-Factor Authentication (MFA):Requires users to provide multiple forms of verification to access a system. 
  • Role-Based Access Control (RBAC):Assigns permissions based on user roles rather than individual users. 

Effective IAM reduces the risk of unauthorized access, data breaches, and insider threats, while also simplifying user management, improving productivity, and ensuring compliance with legal or regulatory requirements.
