Git for Security Professionals

What Git for Security Professionals teaches: give your security work a memory. Version control for detection rules, IR playbooks, scripts, policy-as-code, and compliance evidence, with a full audit trail of who changed what and why, safe collaboration through branches and review, and the security practices Git needs that a developer course skips. The discipline, the toolchain, and how the course is built. Start here.

The foundation the whole course stands on. Configure Git for provenance and make your first commit, learn the four-stage model that explains where a change lives, understand what a commit actually is, read history with log, show, diff, and blame, work with a remote, and structure a repository for real security work across detection, DFIR, architecture, and governance.

Turn the foundations into fluency. Run the daily edit-stage-commit-sync loop as a discipline, write commit messages that hold up under review, stage selectively so every commit is one clean change, undo safely whichever way you got it wrong, stash and clean a working tree, and configure Git so the loop is fast and yours.

Work alongside a team without collisions. Understand what a branch really is, do isolated work on a feature branch, merge it back with fast-forward and three-way merges, choose between merging and rebasing for a clean history, collaborate through branches on a shared remote, and run the pull request workflow that turns individual change into reviewed, shared work.

Handle the situations collaboration produces. Resolve merge conflicts by reading and editing the markers, rewrite a messy branch into a clean history with interactive rebase, keep rewriting inside the boundary that makes it safe, recover lost work with the reflog, and pin the exact commit that broke something with git bisect.

Secure the repository itself. Keep secrets out of history with ignore rules and the right habits, catch the ones that slip through with secret-scanning hooks and push protection, respond correctly when a secret leaks by rotating before you purge, prove who made a commit with signing, and enforce review and access control so only trusted change reaches what runs.

Turn a version-controlled security repository into a pipeline that ships. Learn what continuous integration and delivery mean for security content, build a pipeline that validates a change on every pull request, test detection content so a broken rule cannot merge, deploy automatically with a scoped credential, secure the pipeline itself against supply-chain risk, and run the whole workflow end to end in the course capstone.

The commands that matter, what each one actually moves, how to recover, and the security work Git makes possible.

Ordered procedures for standing up a content repository, reviewing a change, responding to a leak, and recovering from a bad rewrite.

Four cases reasoned end to end, including the green pipeline that deployed nothing and the commit signed by nobody.

A throwaway repository, a free host account, and the four experiments worth running deliberately.

Every command, workflow, and pipeline snippet from the course in one searchable reference, organized by task, from daily workflow and history recovery to signing, branch protection, and CI/CD. The working kit you carry out of the course to the repositories you run.

Git documentation, commit-signing references, platform docs for branch protection and CI/CD, secret-scanning and history-rewriting tools, supply-chain security resources, and secure-development standards used throughout the Git for Security Professionals course.

Git for Security Professionals end-of-course exam: a committed credential reported as remediated because the file was deleted, testing whether you know the difference between a working tree and a history and what the only real remediation is.
