Implementing aZero Trust modelfundamentally requires robustIdentity and Access Management (IAM) controls because:
* Zero Trust Principles:Never trust, always verify; enforce least privilege.
* Identity-Centric Security:Strong IAM practices ensure that only authenticated and authorized users can access resources.
* Multi-Factor Authentication (MFA):Verifying user identities at each access point.
* Granular Access Control:Assigning minimal necessary privileges based on verified identity.
* Continuous Monitoring:Continuously assessing user behavior and access patterns.
Other options analysis:
* A. Comprehensive process documentation:Helpful but not foundational for Zero Trust.
* B. Robust network monitoring:Supports Zero Trust but is not the core principle.
* C. Routine vulnerability and penetration testing:Important for security but not specifically for Zero Trust.
