Identity and access management

Identity and access management (IAM or IdAM) or Identity management (IdM), is a framework of policies and technologies to ensure that the right users (that are part of the ecosystem connected to or within an enterprise) have the appropriate access to technology resources. IAM systems fall under the overarching umbrellas of IT security and data management. Identity and access management systems not only identify, authenticate, and control access for individuals who will be utilizing IT resources but also the hardware and applications employees need to access.

The terms "identity management" (IdM) and "identity and access management" are used interchangeably in the area of identity access management.

Identity-management systems, products, applications and platforms manage identifying and ancillary data about entities that include individuals, computer-related hardware, and software applications.

IdM covers issues such as how users gain an identity, the roles, and sometimes the permissions that identity grants, the protection of that identity, and the technologies supporting that protection (e.g., network protocols, digital certificates, passwords, etc.).

Identity management (ID management) – or identity and access management (IAM) – is the organizational and technical processes for first registering and authorizing access rights in the configuration phase, and then in the operation phase for identifying, authenticating and controlling individuals or groups of people to have access to applications, systems or networks based on previously authorized access rights. Identity management (IdM) is the task of controlling information about users on computers. Such information includes information that authenticates the identity of a user, and information that describes data and actions they are authorized to access and/or perform. It also includes the management of descriptive information about the user and how and by whom that information can be accessed and modified. In addition to users, managed entities typically include hardware and network resources and even applications. The diagram below shows the relationship between the configuration and operation phases of IAM, as well as the distinction between identity management and access management.

Access control is the enforcement of access rights defined as part of access authorization.

Digital identity is an entity's online presence, encompassing personal identifying information (PII) and ancillary information. See OECD and NIST guidelines on protecting PII. It can be interpreted as the codification of identity names and attributes of a physical instance in a way that facilitates processing.

In the real-world context of engineering online systems, identity management can involve five basic functions:
