Mitigation Strategies Analysis for mobile-dev-inc/maestro

Mitigation Strategy: Data Masking and Scrambling in Test Environments (UI Context)

  • Mitigation Strategy: Data Masking and Scrambling in Test Environments (for Maestro UI Testing)
  • Description:
    1. Identify Sensitive UI Elements: Catalog UI elements within your application that display sensitive data during Maestro UI tests. This includes text fields, labels, and any other UI components showing PII, financial data, etc.
    2. Implement UI-Level Masking: Modify your application's test environment configuration to mask or scramble sensitive data specifically in the UI layer. This could involve:
      • Using test-specific configurations to display masked data in UI tests.
      • Implementing UI interceptors or proxies that dynamically mask data before it's rendered in the UI during tests.
      • Utilizing Maestro's capabilities to interact with UI elements that already display masked data in test environments.
    3. Verify UI Masking in Maestro Tests: Design Maestro tests to explicitly verify that sensitive data is indeed masked in the UI during test execution.
    4. Avoid Real Data in Maestro Flows: When designing Maestro flow files (.yaml), ensure you are using placeholder data or test-specific data that is not real or sensitive.
  • List of Threats Mitigated:
    • Accidental Data Exposure During Maestro UI Tests (High Severity): Risk of real sensitive data being displayed and potentially captured in Maestro screenshots, recordings, or logs during UI tests.
    • Data Breach via Maestro Test Artifacts (High Severity): If Maestro test outputs (screenshots, recordings, logs) containing unmasked sensitive data are compromised, it can lead to a data breach.
    • Compliance Violations (Medium Severity): Failure to protect sensitive data displayed in UI tests can lead to violations of data privacy regulations.
  • Impact: Significantly Reduces risk of data exposure specifically through Maestro UI testing artifacts.
  • Currently Implemented: Partially implemented. Backend data scrambling is used, but dedicated UI-level masking for tests and verification within Maestro tests are missing.
    • Location: Backend data scrambling scripts in staging-environment repository.
  • Missing Implementation: UI-level masking within the application frontend specifically for test environments, Maestro tests to verify UI masking, and guidelines for avoiding real data in Maestro flow files.

Mitigation Strategy: Secure Logging Practices for Maestro Output
