Git for Security Professionals

Version control every change. Prove who made it.

Security work is made of files that change, that several people touch, and that someone will one day ask you to account for: detection rules, IR playbooks, scripts, Conditional Access policy, control evidence. Kept in a shared folder, that work has no memory, no safe way to edit together, and no proof of who changed what or when. This course teaches Git for that work specifically. You put any artifact under version control, collaborate through branches and review, keep secrets out and purge them when they slip in, sign your commits for provenance, and automate the checks that protect a repository, across detection, DFIR, architecture, and governance.

What you'll be able to do

✓Put any security artifact under version control with a full, attributed history: detection rules, IR playbooks, scripts, policy exports, and audit evidence
✓Run the daily Git workflow with intent: stage precisely, write commit messages that hold up, read history with log, diff, and blame, and undo changes without panic
✓Collaborate on shared security work through branches and pull requests, with review and branch protection so nothing reaches main unreviewed
✓Resolve merge conflicts and recover lost work with the reflog, and know exactly when rewriting history is safe and when it is not
✓Keep secrets out of a repository, purge them from history when they slip in, and sign your commits so provenance is verified rather than typed
✓Build CI that validates a security artifact before it ships, and run the whole workflow end to end from a branch to a protected, automated deploy

Course overview

Git for Security Professionals teaches version control as a security practitioner needs it, not as a software developer is taught it. You start from your first commit and the model underneath it, learn the daily workflow, collaborate on shared work through branches and pull requests, resolve conflicts and recover lost work, secure the repository itself, and automate the checks that protect it. Every example is a real security artifact, and the moves are the same whether the file is a Sigma rule, a policy export, a collection script, or an evidence sheet. Learn how to:

✓ Put any security artifact under version control with a full, attributed history
✓ Answer who changed a rule, policy, or script, when, and why, from the history itself
✓ Collaborate through branches and pull requests so no change lands on main unreviewed
✓ Resolve merge conflicts and recover work without losing either side
✓ Keep secrets out of a repository, purge them when they get in, and sign your work for provenance

By the end you can put your own work under version control, change it safely alongside a team, and stand behind its history in an audit or an investigation.

Who this course is for

You work in security and you work with files that change: a detection engineer versioning rules, a DFIR analyst versioning collection scripts and case notes, an architect versioning Conditional Access policy and infrastructure baselines, a GRC professional versioning policies, control mappings, and audit evidence. There is no minimum experience and no gatekeeping. Every command and concept is taught at first use, so you can start here whether you have never run a Git command or have used it loosely for years and want to work with intent. It is for you if you want to:

✓ Stop keeping critical security work in shared folders with no history or review
✓ Contribute to a shared repository confidently, without fear of overwriting a colleague
✓ Keep a leaked secret from ever reaching a repository, and clean one up when it does
✓ Prove the provenance of a change to an auditor or an investigator

What you'll learn

By the end of Git for Security Professionals you will be able to:

✓ Configure Git for provenance and put a repository under version control from the four-stage model up
✓ Run the daily workflow with intent: stage precisely, read history, and undo changes without panic
✓ Read who changed a line and why with log, show, diff, and blame
✓ Branch, open a pull request, and review a change before it merges, with protection on main
✓ Resolve merge conflicts and recover lost commits with reflog
✓ Scan for secrets, prevent them with pre-commit hooks, and purge them from history when needed
✓ Sign commits so the history carries a verified author, not a name someone typed
✓ Build CI that validates a security artifact before it ships, and run the whole workflow end to end

Key course takeaways

✓ A working command-line fluency in Git, learned as moves you repeat rather than commands you memorize
✓ The collaboration model that lets a team change shared security work safely and with a review trail
✓ The security practices a developer course skips: secret hygiene, history purging, and signed provenance
✓ A repeatable habit of putting security work under version control, whatever discipline you work in

Things you need to know

What are the prerequisites for this course?

Comfort editing a text file and running a command in a terminal. That is all. No prior Git experience is required, and every command is taught at first use. An experienced reader can skip past what they already know using the orientation at the top of each section.

Do I need a GitHub account or any particular platform?

No. You can follow the whole course with Git on your own machine, and the hosting and review concepts are taught against GitHub, GitLab, and Azure DevOps so they apply wherever your team works. Everything is demonstrated with security artifacts and sample data, never production secrets or live systems.

Is this a detection-engineering course?

No. Detection is one of four disciplines the course serves. The examples rotate across detection rules, DFIR scripts and case artifacts, architecture and identity policy, and GRC evidence, because the version-control skills are the same for all of them. You anchor on whichever artifact you already know and the moves transfer to the rest.

How does this relate to SEC407 (Detection As Code)?

This course teaches the version-control foundation: history, collaboration, secret hygiene, and provenance for any security artifact. SEC407 teaches the pipeline that operates a detection library at scale, and it assumes exactly the Git fluency this course builds. Git for Security Professionals is the upstream skill; SEC407 is one place you apply it. Neither is a prerequisite for the other, but this one comes first.

How will the course benefit your career?

Version control is assumed knowledge across modern security roles, and the practitioners who use it with intent, rather than copying commands and hoping, stand out. Because the skill is vendor-neutral and applies to every discipline, it travels with you regardless of the tools an employer runs, and it is the entry point to detection-as-code, infrastructure-as-code, and policy-as-code work.

Version and changelog

Current version: 1.0  |  Last updated: July 2026

July 2026, v1.0: Full course launch, rebuilt from the original Git skill into six teaching modules across four phases, framed by a course orientation and two reference modules. Covers Git foundations, the daily workflow, branching and collaboration, conflicts and recovery, securing Git with secret hygiene and signed provenance, and CI/CD for security work, ending with a capstone that runs the whole workflow end to end. The student finishes able to put any security artifact under version control and stand behind its history.
