Editing Chapter 6: Edge Security and Privacy (section)

==='''Authentication and Access Control Mechanisms'''===

Given the distributed and autonomous nature of edge devices, strong identity and access management (IAM) mechanisms are vital for secure operations.

'''Public Key Infrastructure (PKI) and Device Identity''': Each edge device is provisioned with a unique cryptographic identity (certificates or keys), enabling mutual authentication and secure bootstrapping of trust.

'''Multi-Factor Authentication (MFA)''': Administrative access to edge systems incorporates multiple layers of verification, such as passwords, smart tokens, and biometrics.

'''Role-Based Access Control (RBAC)''': This mechanism limits access based on the user’s or device’s role, reducing the risk surface in case of a security breach.

'''Zero Trust Architecture (ZTA)''': Built on the principle of “never trust, always verify,” ZTA ensures that every user, device, or service must be continuously authenticated and authorized, regardless of location.
