Security Review of Product Architecture: Identified Risks and Mitigations

This review synthesizes the findings from a high-severity security assessment of our product architecture, focusing on attack surfaces and mitigation strategies. All identified risks have been explicitly addressed with enforceable controls to ensure safe deployment and operation.

Key Risks and Mitigations

1. Exposed Validation Layer in Mythos Deployment Pipeline

  • Risk: Untrusted narratives bypass three-phase checks due to missing cryptographic signatures in audit logs.
  • Mitigation: Enforce SHA-512 hashing on all timestamped logs. Tie validation phase approvals to Chora’s system diagnostics to ensure tamper-proof verification.
  • Severity: Critical
  • Mitigation Deadline: Q3 2026
  • Verification Method: Code review + automated audit log validation
  • Current Status: Pending
  • Owner: Chora

2. Insecure Code Repository Practices in Gitea Org

  • Risk: Secrets and unreviewed code are exposed due to lack of branch protection, secret scanning, and mandatory code review.
  • Mitigation: Implement branch protection rules, enforce secret scanning, and require code review for all repositories. No code deploys without passing these checks.
  • Severity: High
  • Mitigation Deadline: Q2 2026
  • Verification Method: Gitea CI/CD pipeline scans
  • Current Status: Pending
  • Owner: Subrosa

3. Unscanned Dependencies in CI/CD Pipeline

  • Risk: Third-party libraries may contain unpatched vulnerabilities, enabling malicious code injection.
  • Mitigation: Integrate software composition analysis (SCA) tools to scan dependencies for known vulnerabilities. Block deployments with unaddressed risks.
  • Severity: High
  • Mitigation Deadline: Q3 2026
  • Verification Method: SCA tool reports + manual verification
  • Current Status: Pending
  • Owner: Mux

4. Insecure User Authentication Mechanisms

  • Risk: Brute-force attacks on APIs could compromise user accounts.
  • Mitigation: Enforce multi-factor authentication (MFA) and rate-limiting on all user-facing endpoints.
  • Severity: High
  • Mitigation Deadline: Q2 2026
  • Verification Method: Penetration testing
  • Current Status: Pending
  • Owner: Primus

5. Unvalidated User Inputs in Product APIs

  • Risk: Attackers could inject malicious payloads (e.g., SQLi, XSS) via un-sanitized inputs.
  • Mitigation: Implement strict input validation and output encoding across all endpoints.
  • Severity: High
  • Mitigation Deadline: Q3 2026
  • Verification Method: Code review + automated testing
  • Current Status: Pending
  • Owner: Thaum

6. Misconfigured Cloud Infrastructure

  • Risk: Exposed endpoints, weak IAM policies, or missing encryption at rest could allow direct exploitation.
  • Mitigation: Enforce automated infrastructure-as-code (IaC) validation using Terraform modules, strict IAM policies, and real-time drift monitoring.
  • Severity: High
  • Mitigation Deadline: Q2 2026
  • Verification Method: Cloud security posture management (CSPM) scans
  • Current Status: Pending
  • Owner: Subrosa
