| Identity Analytics and Intelligence (IdA) | Identity analytics and intelligence mean looking at entitlement data, looking at the assignment of that, and trying to figure out and define what risk looks like. IdA provides a risk-based approach for managing system identities and access, with the intention of centralizing governance, visibility, and reporting for access-based risk. | Introduction to Identity - Part 1: Admin-time (v2) |
| Identity and Access Management (IAM) | Identity and Access Management (IAM) is the discipline used to ensure the correct access is defined for the correct users to the correct resources for the correct reasons. | Authentication and Authorization |
| Identity Federation | An identity federation is a group of computing or network providers that agree to operate using standard protocols and trust agreements. In a Single Sign-On (SSO) scenario, identity federation occurs when an Identity Provider (IdP) and Service Provider (SP) agree to communicate via a specific, standard protocol. The enterprise user will log into the application using their credentials from the enterprise rather than creating new, specific credentials within the application. By using one set of credentials, users need to manage only one credential, credential issues (such as password resets) can be managed in one location, and applications can rely on the appropriate enterprise systems (such as the HR system) to be the source of truth for a user's status and affiliation.Identity federations can take several forms. In academia, multilateral federations, where a trusted third party manages the metadata of multiple IdPs and SPs, are fairly common. This article focuses, however, on the enterprise use case where bilateral federation arrangements, where the agreements are one-to-one between an IdP and an SP, are the most common form of identity federation in use today. | Federation in the Enterprise |
| Identity Governance and Administration (IGA) | a discipline that focuses on identity life cycle management and access control from an administrative perspective. | Introduction to Identity - Part 1: Admin-time (v2) |

| Identity Hub or Repository | The place where users can store their encrypted identity-related information. An identity hub can be anywhere – on the edge, on the cloud, or on your own server. Its purpose is to store personal data. Some implementations may allow other entities to access the identity hub of the user if the user specifically grants such access. You can think of an identity hub as the individual's personal data store. | A Peek into the Future of Decentralized Identity |
| Identity Information Authority (IIA) | This represents one or more data sources used by the IDM as the basis for the master set of principal/subject identity records. Each IIA may supply a subset of records and a subset of attributes. Sometimes the IIA is distinguished from the Identity Information Provider or IIP. We use IIA to include the service that actually provides the information as well as the root authority. This corresponds to Identity Information Source in ISO/IEC 24760-2 and Identity Sources in Internet2. | IAM Reference Architecture |
| Identity Management (IDM) | A set of policies, procedures, technology, and other resources for maintaining identity information. The IDM contains information about principals/subjects, including credentials. It also includes other data such as metadata to enable interoperability with other components. The IDM is shown with a dotted line to indicate that it is a conceptual grouping of components, not a full-fledged system in itself. | IAM Reference Architecture |
| Identity Proofing | accruing evidence to support "who this is." Identity proofing is the last, but not the least, important part of this admin-time section. This is the process of collecting and verifying information about a person for the purpose of providing an account or a corresponding credential. This is typically performed before an account is created or the credential is issued, or a special privilege is granted. | Introduction to Identity - Part 1: Admin-time (v2) |
| Identity Provider (IdP) | An Identity Provider (IdP) performs a service that sends information about a user to an application. This information is typically held in a user store, so an identity provider will often take that information and transform it to be able to be passed to the service providers, AKA apps. The OASIS organization, which is responsible for the SAML specifications, defines an IdP as "A kind of SP that creates, maintains, and manages identity information for principals and provides principal authentication to other SPs within a federation, such as with web browser profiles." | Federation in the Enterprise, Authentication and Authorization |
| Identity Provider (IDP) | Identity Provider or IDP is a common term. We treat this as a subset of Identity Management. It consists of the service interfaces: AuthN/Assertion, Service Provisioning Agent, Session Management, Discovery Services, and Metadata Management. | IAM Reference Architecture |
| Identity Register | This is the datastore that contains the enrolled entities and their attributes, including credentials. See the IDM section for elaboration. The terms Directory, Identity Repository, and Attribute Store are sometimes used as synonyms. | IAM Reference Architecture |
| Identity Theft Law | Laws governing crimes in which the perpetrator gains access to sensitive personal information belonging to the victim (such as birth dates, passwords, email addresses, driver's license numbers, social security numbers, financial records, etc.), and then uses this information to impersonate the victim for personal gain, such as to commit fraud, establish credit in the victim's name, or access the victim's accounts. | Laws Governing Identity Systems |

| OAuth 2.0 | OAuth 2.0 is an open-source protocol that allows Resource Owners such as applications to share data with clients by facilitating communication with an Authorization Server. That data takes the form of credentials given to applications to obtain information/data from other applications. The Authorization Server is usually the Identity Provider (IdP). The Authorization Server (AS) may provide authorization directly or indirectly. For example, the AS may supply attributes or profile data of the Resource Owner or provide access to data that can later be used for authorization purposes, such as entitlements from an Identity Management or Governance Solution. | Federation in the Enterprise |
