Identity and Access Management
Identity and Access Management (IAM) is a framework for managing digital identities and controlling access to resources within an organization. It consists of processes, policies, and technologies that ensure the right individuals have access to the right resources at the right time. IAM involves verifying user identities through authentication mechanisms (e.g., passwords, tokens, biometrics) and managing user access through authorization. Single Sign-On (SSO) and Privileged Access Management (PAM) are examples of IAM solutions that streamline system access for users, while providing administrators with better management and oversight capabilities. An effective IAM system maintains a balance between security, privacy, and user experience.

What is Identity and Access Management?
Identity and Access Management (IAM) is a framework of policies and technologies ensuring that the right individuals (identity) have access to the right resources at the rights times for the right reasons (access management). It involves processes for identifying, authenticating, and authorizing individuals or groups.
Importance of IAM
IAM serves a crucial role in information security as it governs who has access to which resources and when. It ensures that unauthorized individuals do not gain access to sensitive data and systems.
How IAM works
IAM starts by identifying the user through methods like usernames or emails. Once the user is identified, authentication takes place usually through passwords, biometrics, or digital certificates. If authentication is successful, the user is then authorized to access only the resources they have rights to.
