RBAC & Permissions Framework

Core Principles

Least Privilege

Users are granted only the minimum permissions required to perform their specific job functions. No default administrative access.

Separation of Duties

Critical workflows require multi-role validation. No single entity can initiate, approve, and execute high-impact operations.

Zero Trust Architecture

Continuous verification of identity and device health. Context-aware access policies adapt in real-time based on risk signals.

Audit & Accountability

Every permission grant, role change, and sensitive action is logged immutably for compliance and forensic analysis.

Standard Role Definitions

System Administrator

Critical

Full infrastructure lifecycle management. Restricted to senior engineering leads with MFA and hardware token verification.

Division Manager

Operational oversight within assigned business units. Can approve workflows, manage team access, and view cross-departmental analytics.

Policy Assignment Syntax

All permissions are enforced via JSON-based policy documents pushed to the central IAM gateway.

    "mfa_required": true,

    "session_timeout": 3600

}
