Complete Guide to Open Source Code Security: How to Protect NHS Repositories

This guide explains the theoretical concept behind NHS England's decision to make almost all of its open-source repositories private. This change is motivated by the concern that advanced AI models may identify security vulnerabilities in public code.

The initiative is useful for those working in cybersecurity and developers collaborating on open-source projects in the healthcare sector. Understanding this transition helps assess the impact on transparency, collaboration, and the security of healthcare systems.

• Objective: Provide a clear and detailed overview of NHS England's decision to switch to private repositories.
• Target Audience: IT professionals, developers, cybersecurity experts, and anyone interested in healthcare data management.
• Usefulness: Understand the reasons behind this choice and the implications for the security and transparency of open-source projects.

Prerequisites

• Hardware: A computer with internet access.
• Software: An updated web browser.
• GitHub Account: A GitHub account to access public repositories.

Procedure to Request an Exception to Keep NHS England Repositories Public

This guide will show you how to request an exception to keep NHS England repositories public, following the internal guidelines reported.

• Step 1: Verify the current date. Make sure you are within the request period, which ends on May 6, 2026.
• Step 2: Identify the repository you want to keep public. Check the NHS.UK GitHub organization NHS.UK GitHub.
• Step 3: Assess whether the repository meets the criteria for an exception. There must be an exceptional and clear need to keep the repository public.
• Step 4: Prepare to submit the request. Gather all the necessary information to justify the request to keep the repository public.
• Step 5: Submit the request to NHS England's Engineering Board. Make sure to include all the required information and meet the deadlines.
• Step 6: Wait for the response. The Engineering Board will evaluate your request and communicate the decision.

Verification and Troubleshooting

At the end of this guide, you will be able to test the accessibility of NHS England repositories and understand the implications of their transition to privacy.

How to Test Repository Accessibility

• Step 1: Verify the Current Status of Repositories
• Step 2: Identify Critical Repositories
• Step 3: Monitor Changes

What to Do If Repositories Become Private

• Step 1: Request Access
• Step 2: Evaluate Alternatives
• Step 3: Participate in the Debate

Security Considerations

Remember that the transition to private repositories is motivated by the concern that advanced AI models may discover security vulnerabilities in public code. However, it is important to consider that privacy does not automatically guarantee greater security, especially if the repositories were previously public and may have been copied or downloaded.

Code security should be addressed through improved review, hardening, and disclosure processes, rather than through the removal of public access to taxpayer-funded code.

Educational Summary and Call to Action

The decision is motivated by the fear that advanced AI models may identify vulnerabilities in public code.

• Key Steps:
  • Understand the reasons behind NHS England's decision.
  • Assess the conflict with the Technology Code of Practice of the British government.
  • Examine the criticisms of open-source advocates.
• Call to Action:
  • If you work in an organization that manages open-source repositories, carefully evaluate the risks and benefits of publishing code.
  • Consider implementing code review and hardening processes to improve security without sacrificing transparency.
  • Participate in the public debate on how to balance security and open-source, especially in critical sectors like healthcare.
