SudoSecurity is an independent technical publication and community for people who build, secure and run software. We publish deep dives, install guides and config walkthroughs across eight areas of technology, written for someone who has already read the docs and wants to know how the thing actually works.
What SudoSecurity is
Most of what we publish is programming and security — web development, application architecture, threat analysis, cryptography — plus the Linux and self-hosting material underneath both, and honest coverage of what AI tooling is actually doing to the job. Every article aims to leave you able to do something: run it, harden it, debug it or explain it to your team.
What we cover
- AI — how models, agents and AI developer tools really work, where they help, and where they quietly fail.
- Cybersecurity — threat analysis, cryptography, hardening and defensive security you can apply today.
- Programming — languages, algorithms and patterns for writing code that holds up.
- Web Development — frontend, backend, performance and accessibility on the modern web.
- Software Development — architecture, Git, testing, CI/CD and the craft of shipping.
- Linux — the command line, system administration and the internals underneath.
- Self Hosting — running your own services: Docker, reverse proxies, backups and home labs.
- Minecraft — server administration, performance tuning, plugins and modding.

The name started as a joke
It came out of a running bit between me and a few friends: put sudo in front of any Linux command and the permission model stops arguing with you. Four letters, and the entire access-control story the system just told you is void.
The joke is wrong, which is exactly why we kept it. sudo doesn't defeat security — it is the security model, doing precisely what it was designed to do, with a policy file, an audit trail, and a password prompt. Nothing is bypassed. Everything is authorized.
That's the part that stays with you after fifteen years of keeping other people's systems alive: the incident almost never starts with a broken lock. It starts with a control working perfectly on behalf of someone who shouldn't have asked. The gap between "the mechanism functioned as designed" and "this went very badly" is most of what we write about here.
How we source things
- Primary source first. Source code, spec documents, the vendor's own engineering blog. Tech press for context and framing, not for technical claims. Aggregator and SEO blogs effectively never, and never as the only source for a technical claim.
- Vendor numbers get labelled. If a benchmark comes from a release announcement or a customer case study and we can't find a second independent source, we say so in the text rather than laundering it into a fact.
- Code blocks come from files we actually fetched. When a snippet is ours — written to illustrate a pattern rather than to show a specific vendor's behaviour — the article says so at the bottom.
What we don't do
- No affiliate links, no paid placement, no sponsored posts dressed as coverage.
- No press releases reworded into articles.
- No pretending a tool does more than it does. Every deep dive carries a section on what the thing explicitly does not do — often the most useful paragraph on the page.
The community
SudoSecurity is more than the articles. The forums are where readers ask questions, share configs, post what they've built and argue about the details. A free account gets you new posts by email and a seat in the discussion — nothing else, and no spam.
Disclosure
We also run a Minecraft hosting service. That's a direct commercial interest in a subject we cover, so: we don't benchmark ourselves against competitors, we don't review our own product, and hosting recommendations in our articles are not placements. If you think we've slipped on that, say so on the forums — publicly is fine.
Who writes it
Traven — fifteen years of systems administration before this, now doing editorial, production and the front-end theme work. The rest of the masthead is on Meet the Team.
