FREMONT, CA: Identity and Access Management (IAM) is required for a variety of reasons. First and foremost, one needs IAM to safeguard their systems. Firms do not want anyone to access their personal or confidential information without first proving their identity. Second, businesses must ensure that only approved individuals have access to the resources to which they have been assigned. IAM is also required for accountability. If an action is carried out, an organization needs to know who carried it out. They can examine the system logs associated with a specific identity. Without IAM, there is no way of knowing who performed what action.
Employing an Identity Provider (IdP)
When developers first started building applications that required user authentication, they had to create a user store within the app to keep track of who was who. Besides, the developers had to build an authentication method as well as a roles and rights engine.
This configuration was required for each new application. The issue with this was that whenever the authentication method had to be changed, the developers had to update all of the applications to accommodate the new requirement. For users, developers, and administrators, using a local authentication mechanism is inconvenient:
There is no Single Single-On (SSO) capability, so users must enter their username and password for each application.
This often leads to the use of weak passwords or the reuse of passwords.
Developers must manage another service.
There is no centralized location to handle users.
These issues can be solved by using an IdP. Further advantages of IdP include:
Developers are not required to build strong authentication methods or protect users' passwords.
If we need to change the authentication method, we only do so on the identity provider. The application has not been changed.Users are pleased because they can log in to the identity provider once and then seamlessly access other applications that have been given to them, e.g. (SSO)
Administrators are also satisfied because, if a user leaves the business, the administrator will disable the user in the identity provider and revoke all access immediately.
