docker-admxlint
docker-admxlint packages the C++ admx-lint validator tool into a lightweight, CI/CD-ready Docker image. This container allows system administrators and policy engineers to validate custom Administrative Templates (.admx) and language resource files (.adml) against official Microsoft XML Schema Definitions (XSD) without having to manually build or run dependencies locally.
It is particularly useful for pipeline automation when building custom GPO baselines.
Key Use Cases & Features
- Schema Compliance: Verifies namespace structures, element definitions, and category mappings against official Group Policy schemas.
- Pipeline Integration: Easily integrate ADMX lint checks into GitHub Actions, GitLab CI, or custom DevSecOps pipelines.
- Zero Local Setup: Eliminates the need to configure build environments or C++ compilers on local development workstations.
Quick Usage
Run the linter on your ADMX files by mounting your templates folder into the container:
docker run --rm -v $(pwd)/policies:/workspace harvester57/docker-admxlint:latest /workspace
About Me
Hi, I’m Florian Stosse, just another information security engineer !
Current work
I currently work at the European Space Agency, as a cybersecurity engineer for the Galileo programme, specifically for the Galileo Mission Segment (GMS).
Experience summary
I previously worked at Safran Data Systems, in the Space & Communications business unit. I focused on hardening and securing our embedded Windows 7 and 10/11 platforms (Cortex family of TT&C and high data rate receivers), among other cool things :)
Before that, in October 2018, I started a PhD thesis at CEA-List and ANSSI to work on formal methods applied to software security. More specifically, I was working on software defenses and hardening against hardware vulnerabilities, such as Spectre and Meltdown, using sound static analysis tools (Frama-C in particular).
My thesis was under the supervision of Julien Signoles (CEA), and my advisors were Patricia Mouy (ANSSI) and Florent Kirchner (CEA).
Unfortunately, we had to put a stop to the thesis, but hey, that’s life !
Education summary
I graduated with a M.Sc in Computer Science (major in cybersecurity, minor in embedded systems) from ESIEA Paris (a top French engineering school, part of the “Grandes écoles”) in August 2018. During my graduate studies, I was an apprentice at Bureau Veritas’ R&D center in La Défense, Paris.
I worked in the RAMS department, and my main areas of work were:
- software security (e.g. static analysis, SDLC),
- connected/autonomous vehicles security (e.g. ISO 21434 for automotive security engineering),
- and industrial systems security (e.g. ISO 62443 certification).
