Identity management, authentication techniques, single sign on, and access control monitoring all work together to protect a system and make sure the right people get the right access. Identity management is the process of creating, storing and managing user accounts so the system knows who each user is. Authentication techniques like passwords or biometrics, verify that the user is truly who they claim to be. Single sign on makes this process easier by allowing a user to log in once and automatically access multiple systems without repeating the login steps. Access control monitoring keeps track of who is accessing what, helping detect unusual or unauthorized activity. All of these concepts share the same goal, which is improving security while keeping access simple for users. The text and video both highlight how strong authentication and proper identity management reduce risk, while monitoring and SSO help maintain smooth and secure operations across an organization.
