Identity management is also known as identity and access management (IAM). IAM refers to a framework of policies and technologies for ensuring that the appropriate people in an enterprise have the appropriate access to technology resources. Also called identity management (IdM) , IAM systems fall under the overarching umbrella of IT security.
Identity and access management systems not only identify , authenticate and authorize individuals who will be utilizing IT resources, but also the hardware and applications employees need to access. Identity and Access Management solutions have become more prevalent and critical in recent years as regulatory compliance requirements have become increasingly more rigorous and complex.

It addresses the need to ensure appropriate entree to resources across increasingly mixed technology environments and to meet increasingly demanding compliance requirements.
