Identity and Access Management (IAM) is a framework of policies, technologies, and processes that ensure the right individuals or systems have appropriate access to resources within an organization. IAM systems manage authentication (verifying the identity of users) and authorization (determining what resources or services they can access).

IAM solutions often include features like multi-factor authentication (MFA), single sign-on (SSO), and role-based access control (RBAC). Cloud platforms like AWS, Azure, and Google Cloud provide built-in IAM tools to help organizations manage access to their services securely. IAM helps organizations enforce security, meet compliance requirements, and ensure that sensitive data and systems are accessed only by authorized users or systems.
