Identity management (ID Management) is the organizational process for identifying, authenticating, and authorizing an individual or groups of people to have access to applications, systems or networks by associating user rights and restrictions with established identities.
ID management includes authenticating users and determining whether they are allowed access to particular systems such as country, network or enterprise.
A simple example of ID management is the driver's license. Drivers are identified by their license numbers and user specifications such as restrictions, and are linked to the identifying number.
Therefore, the term for a broad administrative area that deals with identifying individuals in a system and controlling their access to resources within that system by associating user rights and restrictions with the established identity is IDENTITY MANAGEMENT.
