IAM or Identity and Access Management is an enterprise system that determines and assigns roles and access privileges of people on the network. The IAM tool creates roles and determines what resources the roles have the access to and then the assignment of the roles is managed. It also makes user that user can only access the resources they have been assigned with and approved to use. This is applicable to both customer identity management and employee identity management. The gist is to make sure that every user is assigned a single digital identity and each of them is assigned the roles being applicable to them and the access every roles permit them to.
Every user has a digital identity or the login credentials. Then this identity is assigned to the roles which give them access to data and application they need. IAM can also be termed identity management or rights management and is liable for processing user requests for accessing the resources.
