Identity and access management  is a framework of business processes, policies and technologies that  facilitates the management of electronic or digital identities. With an  IAM framework in place, information technology (IT) managers can control  user access to critical information within their organizations. Systems  used for IAM include single sign-on systems, two-factor authentication,  multifactor authentication and privileged access management. These  technologies also provide the ability to securely store identity and  profile data as well as data governance functions to ensure that only  data that is necessary and relevant is shared.
