Identity Management (IdM) is a discipline involving all the tasks required to create, manage, and delete user identities in a computing environment.
IdM begins with the creation of the user account and the assignment of appropriate attributes or permissions to the account. The user account is then enabled for all of the systems to which that user is to be given access.
Identity management tasks during the lifetime of the user account include:
• Adding or removing access to specific systems
• Password resets for lost passwords
• Enforcing periodic password changes to increase network security
When a user leaves the organisation, access must be revoked from every system in the environment.
