IAM is a system that integrates and automates user authorization and authentication with policy control. It is used to secure access and manage permissions of users or any other entity, be it a machine or a process, trying to connect with an asset or application. Organizations are increasingly adopting IAM services as they realize the importance of identity as the primary parameter for granting access rights to IT resources.
The core components of identity access management are user authentication, authorization, and access control. These components work together to provide secure access while also ensuring compliance with internal policies and external regulations.
The main purpose of identity access management is to provide secure access to resources while enforcing a set of policies that help organizations protect their data and systems from unauthorized access. It also provides the necessary control over user identities, authentication, and authorization while allowing users to manage their accounts easily. Organizations use IAM to protect their data, maintain compliance, and manage user identities across multiple systems and applications.
