Provisioning and deprovisioning processes manage user account lifecycles
Single sign-on (SSO) enables users to access multiple systems with one set of credentials
Identity lifecycle management
User onboarding initiates the identity lifecycle, creating accounts and assigning initial access rights
Ongoing management involves updating user information, modifying access privileges, and handling role changes
Regular access reviews ensure users maintain appropriate permissions as their roles evolve
Offboarding process revokes access rights and deactivates accounts when users leave the organization
Automated workflows streamline lifecycle management, reducing administrative overhead and potential errors
Access control principles
Access control principles form the foundation of secure identity and access management systems
Implementing these principles helps organizations protect sensitive data and maintain regulatory compliance
Effective access control balances security requirements with user productivity and convenience
Authentication vs authorization
Authentication verifies the identity of users attempting to access a system or resource

Types of authentication factors
Knowledge factors require information only the user knows (passwords, PINs, security questions)
Possession factors involve physical items the user has (smart cards, mobile devices, hardware tokens)
Inherence factors rely on unique biological characteristics (fingerprints, facial recognition, voice patterns)
Location factors consider the user's physical or network location (GPS coordinates, IP addresses)
Behavior factors analyze user actions and patterns (keystroke dynamics, mouse movements)
