Scope

This policy covers all software published under szl-holdings/*. For the upstream Defense Unicorns ecosystem we contribute to (UDS, Pepr, Zarf — note: SZL does NOT ship an Iron Bank-hardened base image; runtime uses a vanilla UBI9-minimal base, Iron Bank parity tracked-not-baked), please follow their respective security policies.

In scope:

  • Source code, container images, and infrastructure-as-code in this repository.
  • Authentication, authorization, data handling, and cryptographic implementations.
  • Supply-chain risks affecting build artifacts produced from this repository.

Out of scope:

  • Third-party dependencies (please report upstream).
  • Social engineering, physical attacks, or denial-of-service against shared infrastructure.
  • Findings that require physical access to a user's device.

Governance

Vulnerability disclosures are governed by SZL Doctrine v7:

  • No fake security claims; positive status must be verifiable.
  • STAGED-ADVISORY label for gates not yet machine-checked.
  • DSSE receipts on every governance decision.
