  • Missing Implementation: Flame-specific asset loading security policy, input validation for dynamic Flame asset paths, secure server configuration documentation for Flame asset hosting, CSP configuration for web-based Flame games.

Mitigation Strategy: Asset Integrity Checks for Flame Game Assets

  • Description:
    1. Generate Checksums for Flame Assets: Generate checksums (SHA-256) for critical game assets used by Flame (images, audio, etc.) during the build process.
    2. Store Flame Asset Checksums Securely: Store these checksums securely within the game application or in a trusted configuration.
    3. Verify Flame Asset Checksums on Load: When Flame loads critical assets, recalculate their checksums and compare them to the stored checksums before using them in the game.
    4. Handle Flame Asset Integrity Failures: If checksum verification fails for a Flame asset, prevent asset loading and implement error handling to avoid using potentially tampered assets in the game.
  • List of Threats Mitigated:
    • Flame Asset Tampering (Medium Severity): Prevents the game from using modified or malicious assets that could alter game behavior or introduce malicious content within the Flame game.
    • Flame Asset Corruption (Low Severity): Detects accidental corruption of game assets used by Flame, ensuring game stability and correct asset rendering.
  • Impact:
    • Flame Asset Tampering: Medium reduction. Increases confidence in the integrity of assets used by Flame, reducing risks of malicious asset substitution within the game.
    • Flame Asset Corruption: Low reduction. Helps ensure data integrity of game assets and Flame application stability.
  • Currently Implemented: No (Likely not implemented specifically for Flame game assets)
