Ask a dozen information technology administrators and engineers what Identity Management and you will get two dozen answers. It need not be complicated. Think of identity management as an office building.
Not everyone can get into every room in the building, and not everyone can get into all the file cabinets even if they are allowed to enter the room. Every person has a key that allows people to access the room that the person is allowed to access.

Better yet, think of it as a luxury hotel. When you get a "lock" on the front desk, allowing you to enter your room, indoor gym, indoor swimming pool area, and a business center. It does not allow you access to the janitor's closet, the other in the hotel room or kitchen. You need a different key for it. You only have permission to enter certain areas defined by management.
Similarly, the computer network is like a hotel, guest rooms and each represents a file, database, or application on the network. Employees working in the hotel is the user. The keys are the rights and privileges that the administrator doles out to everyone on the network. These rights provide access to files, applications, or databases.
Such as hotel security, identity management is the most important form of protection of information that agencies and companies use. However, it is also among the most used or not correctly implemented all information security practices.
Identity management is more than just allow users to log on; identity management control what users can do, like putting locks on the doors and walls inside the hotel. In other words, the IDM is more than giving rights to the user so they can log on.
The administrator provides credentials, such as a number, for workers. That credential number / giving workers access to the network and determine what resources are available. A credential that can also alert administrators when a user accesses a restricted area.
