# Governance Model Specifications

## Overview
The Governance Model defines privilege models for data access, ensuring compliance with enterprise security and governance standards. It acts as a layer for controlling access to user queries and relevant data.

## Responsibilities
- Define and enforce access privileges based on roles, teams, and organizational hierarchy.
- Ensure compliance with enterprise security policies.
- Provide administrators with tools to configure and monitor access settings.

## Admin Settings
- Manage access to:
  - Users.
  - Drive folders.
  - Chat spaces.
- Define who can query what data based on roles and teams.

## Privilege Models
- Role-based access control (RBAC): Assign permissions based on user roles.
- Team-based access: Restrict data access to specific teams or departments.
- Hierarchical access: Allow leads to access data for their reporting teams.

## Technical Specifications

### Privilege Models
- Role-based access control (RBAC): Permissions are assigned based on user roles.
- Team-based access: Data access is restricted to specific teams or departments.
- Hierarchical access: Leads can access data for their reporting teams.

### Admin Settings
- Admins can configure access to:
  - Users.
  - Drive folders.
  - Chat spaces.
- Access settings are stored in the `access_policies` table.

## Implementation Details

### Access Control Enforcement
- Queries are filtered based on the user's role and team.
- Access policies are checked against the `access_policies` table before executing queries.

### Audit Logging
- All access control changes and data queries are logged in the `audit_logs` table.
- Logs include:
  - `user_id`: ID of the user making the change or query.
  - `action`: Type of action (e.g., query, policy update).
  - `timestamp`.

## User Roles and Permissions

### Administrators
- Define and enforce access policies.
- Monitor access logs and resolve privilege violations.

### Regular Users
- Query data based on their assigned roles and teams.

## Observability
- Audit logs for access control changes and data queries.
- Metrics for access patterns and privilege violations.

## Open Questions / TODO
- Define escalation policies for privilege violations.
- Explore automated compliance checks for access settings.
