A free, independent DevSecOps education platform
SecOpsLog is a free, independent DevSecOps education platform. It publishes hands-on, command-first tutorials, structured courses, and field notes on how to build security into the way software is shipped — instead of bolting it on after the fact. Everything is free to read, works without an account, and is written to be run, not just skimmed.
The material is aimed at the engineer who has to make it work on Monday: platform and DevOps engineers, SREs, security engineers, and developers who own their own deployments. Lessons are built around the commands you would run, the output you should expect, and the failure the control prevents, and each course section ends with a self-test so you know it stuck.
The curriculum follows the whole delivery pipeline, from Linux and container internals up through Kubernetes security, CI/CD and software supply-chain integrity, secrets management, Infrastructure as Code, and detection. Security is not a separate chapter — it runs through every layer above.
What you will find here
- 50+ structured courses and 800+ lessons — leveled beginner to advanced, each ending in a graded exam.
- Guided learning paths — role-based roadmaps that sequence the courses for a job you are aiming at.
- One-page cheat sheets — fast command references for a single tool.
- Side-by-side tool comparisons — Terraform vs OpenTofu, Argo vs Flux, Helm vs Kustomize, and more.
- Leveled interview questions — from Beginner to Expert, tagged by level.
- Field notes on the blog — short, worked write-ups on problems from real systems.
How the material is written
The teaching philosophy is simple: nothing is hand-wavy. Commands are written out in full rather than described, and anything you must replace with your own value is marked as a placeholder. Where a topic has real trade-offs — a scanner that flags too much, a policy that blocks a valid deploy — the lesson says so and shows how to tune it. The goal is that you can run the steps on your own machine or cluster, not just read about them. There is no advertising, no tracking cookie, and no paywall anywhere on the site. Technical articles carry one of two honest verification states — command-tested (the commands were executed in a reproducible environment, with the versions recorded) or documentation-verified (the claims were checked against first-party documentation) — shown on each article and explained in full on the methodology page.
An independent project
SecOpsLog is an independent education project. It is not affiliated with, endorsed by, or a product of any vendor — including any commercial security-operations, SIEM, or logging platform. The name refers to a log of hands-on DevSecOps learning, and the whole site is about teaching practitioners, not selling a tool.
Get in touch
Corrections, suggestions, and questions are genuinely welcome — spotting an out-of-date flag or a better way to do something makes the material better for everyone. Reporting a broken command or an outdated reference is easiest if you include the article URL, the tool and version you used, and the behavior you saw.
