Identity and Access Management (IAM)

Printer-friendly versionPrinter-friendly version

Identity and Access Management (IAM) is a framework consisting of technical, policy, and governance components that allows an organization to:

* identify individuals
* link identities with roles, responsibilities, and affiliations
* assign privileges, access, and entitlements based on identity and associations

IAM permits data stewards and service providers to control access to information and/or services, according to an individual's identity, roles and responsibilities. The following diagram presents an overview of the systems and resources necessary for an Identity Management System.

IAM is comprised of four main areas:
Credentialing (assignment of an unique token to an entity needing access to resources)
Authentication (act of validating proof of identity)
Authorization (act of affording access to only appropriate resources and functions)
Accountability (ensuring against illegitimate utilization of an entity’s authority)

In the future you will be able to access more information about this service.
