🔄 Core Principles of the Zero Trust Model

Continuous Verification: Every access attempt is verified regardless of location or network
Least Privilege Access: Minimal permissions for fulfilling specific tasks
Assume Breach: The network is treated as already compromised
Microsegmentation: Granular subdivision of the network with specific access policies
Data-Centric Protection: Focus on protecting data rather than network perimeters

Core Principle: Permissions are tied to roles; users are assigned roles
Structure: Hierarchical organization of roles (e.g., Employee → Department Head → Division Head)
Implementation: Easier to implement and manage than ABAC
Scalability: Role explosion can occur in complex organizations
Use Case: Organizations with clearly defined hierarchies and responsibilities

Dynamics: ABAC enables real-time decisions; RBAC is more static
Compliance: ABAC provides more detailed audit trails for regulatory requirements
Hybrid Models: RBAC combined with attribute-based constraints merges the advantages of both approaches
Implementation Effort: RBAC is easier to introduce; ABAC offers greater long-term flexibility
