Role-Based Controls

Purpose

This page defines how role-based controls are described, interpreted, and constrained in documentation. It serves as a governance reference for expressing roles, permissions, and responsibility boundaries.

This page does not define enforcement behavior, security guarantees, or system correctness.

Definitions

Role: A named collection of responsibilities and permissions assigned to a principal.

Permission: An allowed action or operation associated with a role.

Principal: An identity (user, service, or operator) to which one or more roles may be assigned.

Assignment: The association between a principal and a role.

Interpretation Rules

Roles must be documented as descriptive groupings of permissions, not as proof of trustworthiness or intent.

A role name must not be interpreted as implying capability beyond its explicitly documented permissions.

Multiple roles assigned to a principal must be interpreted independently unless an explicit combination rule is documented.

Role definitions should be stable identifiers and must not rely on implicit or contextual meaning.

Disallowed Inferences

Do not infer security, safety, or compliance guarantees from the existence of role-based controls.

Do not infer that a role assignment prevents misuse, abuse, or policy violations.

Do not infer that roles represent organizational authority, legal responsibility, or audit approval.

Do not infer that role separation alone enforces least-privilege or segregation-of-duties.

Boundary Conditions

This page governs documentation and interpretation of role-based controls only.

It does not specify identity verification methods, permission enforcement mechanisms, or runtime evaluation logic.

It does not define role lifecycle management, onboarding, offboarding, or incident handling.

Non-Guarantees

This document does not guarantee correct role assignment, absence of privilege escalation, or completeness of permission definitions.

This document does not guarantee that documented roles align with operational practice or real-world access.

Validation Checklist

Are roles defined as explicit permission groupings rather than implied authority?

Are permissions listed or referenced clearly for each role?

Are role names free from claims of trust, safety, or compliance?

Are boundary statements present to prevent over-interpretation of role assignments?

Is it clear that role-based controls are descriptive, not outcome-guaranteeing?

Forbidden Patterns

Avoid role names that imply guarantees (e.g., “trusted,” “secure,” “approved”).

Avoid statements that treat roles as proof of intent, legitimacy, or correctness.

Avoid collapsing multiple roles into a single implied authority without explicit documentation.
