Permission Hierarchy

System Level:

• System Admin → Full platform control, settings management

Organization Level:

• Admin → Full organization control, member management
• Manager → Team coordination, permission assignment
• Member → Standard access
• Viewer → Read-only access

Entity Level (per boat/aircraft/vehicle):

• Admin → Full entity control
• Manager → Can grant/revoke permissions to other users
• Editor → Can modify entity data
• Viewer → Read-only access

Super Admin Permission Delegation

Use Case: Agency Managing Multiple Boats

Scenario: Marine Services Agency manages 10 boats. They need to:

1. Grant technicians access to specific boats
2. Give captains full control of their assigned boats
3. Allow office staff read-only access to all boats

Implementation:

// 1. Organization Admin grants entity permission to technician
POST /api/permissions/entities/boat-123
Authorization: Bearer {org-admin-token}
{
  "userId": "tech-user-id",
  "permissionLevel": "editor",  // Can modify boat data
  "expiresAt": null  // No expiration
}

// 2. Grant captain full control
POST /api/permissions/entities/boat-456
Authorization: Bearer {org-admin-token}
{
  "userId": "captain-user-id",
  "permissionLevel": "manager",  // Can grant permissions to others
  "expiresAt": null
}

// 3. Grant office staff read-only to all boats
POST /api/permissions/entities/boat-789
Authorization: Bearer {org-admin-token}
{
  "userId": "office-user-id",
  "permissionLevel": "viewer",  // Read-only
  "expiresAt": null
}

// 4. List all permissions for a boat (audit)
GET /api/permissions/entities/boat-123
Authorization: Bearer {org-admin-token}

// Response:
{
  "success": true,
  "permissions": [
    {
      "userId": "tech-user-id",
      "userName": "John Tech",
      "permissionLevel": "editor",
      "grantedBy": "admin-user-id",
      "grantedAt": 1729512000
    },
    ...
  ]
}

// 5. Revoke permission when technician leaves
DELETE /api/permissions/entities/boat-123/users/tech-user-id
Authorization: Bearer {org-admin-token}

Permission Verification:

// Before allowing entity access
GET /api/permissions/check/entities/boat-123?level=editor
Authorization: Bearer {user-token}

// Response:
{
  "success": true,
  "hasPermission": true,
  "userPermission": "editor",
  "reason": "User has editor permission"
}

Monitoring & Maintenance

Audit Log Queries

-- Failed login attempts in last 24 hours
SELECT * FROM audit_log
WHERE event_type = 'auth.login'
AND status = 'failure'
AND created_at > strftime('%s', 'now', '-1 day');

-- Permission grants in last week
SELECT * FROM audit_log
WHERE event_type LIKE 'permission.%'
AND created_at > strftime('%s', 'now', '-7 days')
ORDER BY created_at DESC;

-- User activity summary
SELECT
  user_id,
  COUNT(*) as event_count,
  MAX(created_at) as last_activity
FROM audit_log
WHERE user_id IS NOT NULL
GROUP BY user_id
ORDER BY event_count DESC;

Performance Optimization

Indexes Created:

• idx_users_email - Fast email lookups
• idx_users_verification_token - Email verification
• idx_users_system_admin - Admin checks
• idx_refresh_tokens_hash - Token verification
• idx_entity_permissions_user_entity - Permission checks
• idx_settings_category - Category queries

---

Troubleshooting

Common Issues

1. "System administrator privileges required"

• Cause: User not in SYSTEM_ADMIN_EMAILS or is_system_admin = 0
• Solution: Update .env or database flag

2. "Invalid or expired access token"

• Cause: Token expired (15-minute TTL)
• Solution: Use refresh token to get new access token

3. "Failed to decrypt setting value"

• Cause: SETTINGS_ENCRYPTION_KEY changed
• Solution: Re-enter encrypted settings or restore original key

4. "Account is locked. Please try again later"

• Cause: 5 failed login attempts
• Solution: Wait 15 minutes or manually reset in database:

UPDATE users SET failed_login_attempts = 0, locked_until = NULL WHERE email = 'user@example.com';
