User management is a critical process in ensuring access control, security, and operational efficiency in systems and resources. It involves creating user accounts, assigning permissions, managing roles, and implementing policies to restrict access based on user roles or permissions. User profiles provide essential information about users, while role-based access control (RBAC) enables segregation of duties and reduces the risk of data breaches. Policies govern how users can access different parts of a system, including access control, password management, audit and monitoring, and more. The key protocols for user management include Single Sign-On (SSO), OAuth, and SCIM, which enable seamless identity verification, authentication, and provisioning. As user management continues to evolve, trends like zero-trust security models, AI in identity verification, passwordless authentication, and enhanced user experiences are becoming increasingly important.
