[Nov 14, 2025 – Update] Defensible 10 Standards GitHub Repository Now Live

Published by ISAUnited.org

The Defensible 10 Standards (D10S) initiative has reached another major milestone as ISAUnited prepares for the Fall 2025 public launch.We are pleased to announce the creation of the official Defensible 10 Standards GitHub Repository, which will serve as the central hub for documentation, standards development workflows, peer review coordination, and future Sub-Standards submissions.

This repository marks a critical evolution in our engineering process, enabling transparent, collaborative, and version-controlled development consistent with modern engineering and open-standard practices.

A Platform for Engineering Collaboration

The GitHub repository will become the primary workspace for architects, engineers, and vetted contributors participating in the Defensible Standards development lifecycle.This includes:

• Structured workspaces for Parent Standards and Sub-Standards

• D-SSF submission templates and schema documentation

• Peer-review branches and change-control workflows

• Issue tracking for engineering comments, enhancements, and clarifications

• Version control for published drafts and approved editions

By centralizing standards development on GitHub, ISAUnited reinforces its commitment to clarity, discipline, and engineering rigor, ensuring that every change is traceable, reviewable, and defensible.

Preparing for Peer Review and Public Release

The 2025 Draft Edition of the D10S continues to move through final peer review by the ISAUnited Technical Fellow Society, the highest level of technical validation in our standards governance model.The new GitHub repository will allow reviewers and contributors to collaborate more efficiently, supporting:

• Inline engineering commentary

• Technical dispute resolution

• Evidence and V&V tracking

• Cross-domain dependency review

This step represents a significant advancement in how cybersecurity standards should be developed—through transparent, engineering-grade collaboration rather than closed or compliance-driven processes.

Looking Ahead to Open Season 2025

Following the official publication of the Defensible 10 Standards later this year, Open Season Fall 2025 will begin.The GitHub repository will serve as the primary submission and development platform for practitioners worldwide to propose and author new Sub-Standards, expanding the D10S across new technologies, architectures, and emerging domains.

This open, structured environment ensures that all contributions follow the Defensible Standards Schema Function (D-SSF) and adhere to ISAUnited’s engineering and peer-review expectations.

A New Era for Cybersecurity Engineering

The launch of the D10S GitHub repository is more than a technical milestone — it is a strategic step toward making cybersecurity a true engineering discipline.

By enabling traceable development, mathematical verification, and engineering validation, ISAUnited continues to lead the global shift away from checklist compliance toward evidence-based, defensible security architecture.
