Security Policy

Scope

This repository contains documentation, JSON schemas, example detection content and small Python validation tools. It is not a deployed service and processes no user data.

Security issues that are in scope:

Category Example
Tooling vulnerabilities Code execution or path traversal in def_validate.py, def_test.py, score.py or normalize-docs.ps1
Supply chain A compromised or malicious dependency; an unpinned action in a workflow
CI/CD A workflow configuration permitting privilege escalation or secret exfiltration
Harmful guidance Documented procedures that would materially weaken a reader's security posture if followed
Unsafe example content Example rules, runbook commands or fixtures that could cause damage if executed

Out of scope:

  • Detection rules being evadable. All detections are evadable; that is why detection robustness exists. Open a normal issue.
  • Disagreement with a normative requirement. Open a Specification change issue.

Reporting

Use GitHub's private vulnerability reporting: go to the repository's Security tab and select Report a vulnerability. This creates a private advisory visible only to maintainers.

Do not open a public issue for a security report in the first instance.

Please include:

  • What the issue is and where in the repository
  • How to reproduce it
  • What an attacker could achieve
  • Any suggested remediation

Response

Stage Target
Acknowledgement 5 working days
Initial assessment 10 working days
Fix or mitigation for confirmed issues 30 days

This project has a single maintainer and no commercial support. These are good-faith targets, not guarantees. If a report is time-critical and receives no acknowledgement within the target, escalating publicly is reasonable.

Disclosure

Coordinated disclosure. We will agree a disclosure date with the reporter and credit them in the advisory and the changelog unless they prefer otherwise.

A note on the example content

The reference-implementation/ directory contains runbook commands that revoke OAuth grants and disable service principals in Microsoft Entra ID. These are illustrative and are intended to be reviewed and adapted, not pasted into a production tenant.

Treat any executable content in this repository as untrusted input to your change process, exactly as you would treat a detection rule from a public source.
