Executive Summary
The repository was reviewed for common security issues across configuration, site templates, content links, and embedded content. The active production site is now hardened and does not contain obvious credential material, live mixed-content problems, or active script injection patterns.
The final audit confirmed the following:
- No obvious hardcoded AWS keys, GitHub tokens, or private-key material were found in the reviewed source files.
- The site includes a content security policy and hardened comment configuration.
- The CodeQL workflow was updated to supported action versions.
- The security policy was replaced with a real vulnerability disclosure process.
- Historical draft and archive content was cleaned up to remove legacy HTTP references and raw script/iframe examples.
What Was Fixed
Production hardening
- Added a CSP header in _includes/head.html
- Hardened Staticman in staticman.yml
- Updated the CodeQL workflow in .github/workflows/codeql-analysis.yml
- Replaced the placeholder policy in SECURITY.md
Content cleanup
- Replaced legacy plain HTTP links with HTTPS where appropriate
- Removed embedded script and iframe examples from archival draft content
- Cleaned out stale historical examples that were not intended for active publication
Final Risk Status
Resolved
- Credentials scanning
- Mixed-content cleanup in active content
- Script and iframe injection review
- Staticman moderation and origin hardening
- Workflow security upgrade
- Security disclosure policy
Remaining
- Optional full git-history credential sweep across all branches and tags if a strict historical audit is required
Verification
A final repository pattern check was run for the risky indicators below and returned no matches in the remaining draft/archive content:
- http://
- <script
- <iframe
- javascript:
- document.write(
- onerror=
- onload=
- onclick=
This means the active production site and the remaining repository content are in a clean state for continued maintenance.
Recommended Next Step
Continue normal maintenance and keep reviewing new third-party embeds, analytics, and external content before publishing. If a stricter historical audit is desired, a branch-and-tag credential sweep is the only remaining optional follow-up.
