Identity and access management (IAM) plays an important role in IT industries. It is very important to control what a particular user can access. We cannot grant access to everyone for everything. IAM means specifying roles and managing access privileges of individual users. IAM not only includes managing privileges granted to users, but it also includes managing the situations in which those privileges should be granted and when those can be revoked.
With the IAM framework, administrators can manage access to the systems and networks using Role-based Access Control. Access means giving permissions to the user to perform a task based on his role. A user is given a role based on his responsibility towards that organization.
