• Authorization systems determine access rights based on user roles and permissions
• 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
• Involves validating credentials (usernames, passwords, biometrics) against stored information
• Authorization determines what actions or resources an authenticated user can access
• Based on user roles, permissions, and access policies defined by the organization
• Multi-factor authentication (MFA) enhances security by requiring multiple forms of verification

Least privilege principle
