Identity management is the set of processes, tools, and social contracts surrounding the creation, maintenance, and use of digital identities for people, systems, and services. It enables secure access to a set of systems and applications. Its components include data repositories, security, life cycle management, consumables, and management policies. Identity management has strong links to security, trust, and privacy management. It also delivers components of risk management. Traditionally, identity management has been a core component of system security environments. It is used for maintaining account information and controlling access to a system or limited set of applications. Control is usually the primary focus of identity management. For example, an administrator issues accounts to restrict and monitor access to resources. More recently, however, identity management has also become a key enabler of electronic business.
