IAM (Identity and Access Management)
Commonly used in Security, Cybersecurity
Identity and Access Management (IAM) is a framework of policies, processes, and technologies designed to ensure that the right individuals have appropriate access to an organisation's technology resources. It helps organisations securely manage user identities and control permissions across various systems and applications.
How It Works
IAM systems typically involve the creation and management of digital identities for users, devices, and applications. These identities are authenticated through various methods such as passwords, biometrics, or <a href="https://www.ituonline.com/it-glossary/?letter=M&pagenum=4#term-multi-factor-authentication" class="itu-glossary-inline-link">multi-factor authentication. Once authenticated, IAM enforces access controls based on predefined policies, which specify what resources a user or device can access, and what actions they can perform. IAM solutions often include features like single sign-on (SSO), role-based access control (RBAC), and audit logging to monitor and manage access effectively.
By integrating with directory services and other security systems, IAM ensures that access is granted only to authorized users and that permissions are updated or revoked as needed, such as when an employee changes roles or leaves the organisation. This comprehensive approach helps prevent unauthorized access and reduces the risk of data breaches.
Common Use Cases
- Enabling employees to securely access corporate applications with a single login.
- Managing permissions for cloud-based services and resources.
- Implementing multi-factor authentication to enhance security for sensitive systems.
- Automating user onboarding and offboarding processes to ensure proper access control.
- Auditing and reporting on user activity for compliance and security reviews.
Why It Matters
IAM is critical for maintaining security and operational efficiency in any organisation that handles digital data or relies on technology resources. It helps protect sensitive information from unauthorised access, reduces the risk of insider threats, and ensures compliance with regulatory standards. For IT professionals and certification candidates, understanding IAM principles is essential for designing, implementing, and managing secure IT environments. It also plays a key role in supporting digital transformation initiatives by enabling secure, seamless access to resources across diverse platforms and locations.
