Identity-based access control (IBAC) works by granting or denying access to resources based on the identity of the user requesting the access. In IBAC model, every user is assigned with a unique identity, such as username or user ID, that identifies them within the system. The system then establishes policies that govern access permissions for these identities.
The process of IBAC works as follows:
1. Authentication: The user’s identity is established and verified through a login process that requires a password or biometric verification.
1. Authorization: The user’s identity is used to determine the resources or actions that the user is authorized to access based on the policies established by the system.
1. Access control: Based on the authorization policies, the system grants or denies access to the requested resources or actions.
The IBAC model provides a more granular approach to access control as it allows different levels of access to be assigned to different users based on their identity. It is a key component of modern security systems and is commonly used in enterprises, government agencies, and other organizations to manage access to sensitive data and resources.
