Achievement unlocked: SSO for the hypervisor! 🎉
My Proxmox VE is now officially using Keycloak OIDC for authentication, and the setup is fantastic:
- Centralized Users: Managed alongside my other apps (Keycloak using my LDAP as the backend).
- Hardware MFA: Locked down with a FIDO2 stick from @nitrokey
- Unified Control: Centralized policies, logging, and RBAC across the board.
Another great improvement for my HomeLab/SelfHosting setup.

تسعى كل من Agile و DevOps لتحسين إنتاجية التطوير، لكنهما يختلفان في نقطة المركز:
🔹 **الهدف** – Agile يركز على التكيف السريع والتواصل داخل الفريق؛
🔹 **العمليات** – DevOps يدمج التطوير والتشغيل لنسخ أسرع وأأمن.
الاختلاط المثالي يخلق دورة إنتاج متكاملة: Agile يحدد الأولويات، وممارسات DevOps تضمن تسليم مستمر.

True threat modelers don't be usin' no checklists, savvy...
They spy 'em out with their trusty spyglasses!
And when they be layin' down the cards,
they don't waste their breath on soft #games like Solitaire or Sir Tommy!
Nay, they be wagerin' their gold on high-stakes plunder like Cornucopia or EoP!
Threat Modeling is about exploration, not checkbox compliance.
Exploration and innovation happen when playing and exploring like children.

Don't spend too much time on your own; make sure you get regular feedback from developers and testers, and that the developers and testers get regular feedback from you.

Closing thought: Compliance doesn't have to be the brake on your agile engine. Build it into the assembly line, and it becomes the thing that keeps your SaaS platform running smoothly at scale. Try decomposing one regulation this sprint and see how it changes your team's rhythm.

The new OWASP Cornucopia 25th anniversary edition contains both the OWASP Cornucopia Companion and the Website App Edition. The new edition comes with 6 companion suits covering new topics:

One of the most useful Red Hat products I use daily is also one of the least-known: the Red Hat Offline Knowledge Portal (RHOKP).
It is basically a self-hosted, locally searchable mirror of docs.redhat.com + the Red Hat Knowledgebase in a single container image.
Perfect for:
- air-gapped environments
- customer networks with painful proxies
- trains, planes, and terrible WiFi
- anyone who wants docs that still work offline
I wrote up how it works, why I think it matters, and how to run it locally with Podman:

Are you responsible for all the battles?
Then stop and let the monsters rampage a bit.
You can always swoop down and take out the final boss before the credits rolls.
When we take on the battles ourselves, we stop the rest of the team from growing. Growth and learning are important to scale security processes. What happens if you get killed by the super villain, and the others have to fend for themselves?

New post: FreeBSD resource monitoring and accounting.
A practical tour of the base-system toolkit for figuring out *what is actually using my server*: top, vmstat, systat, gstat, netstat/sockstat, procstat, pfctl, and per-jail attribution with kern.racct and rctl.
No ports, no agents. Just FreeBSD.

Could somebody be feeding your LLM the wrong muffin?
LLM7 from the OWASP Cornucopia Companion illustrates how data poisoning can introduce backdoors or malicious behavior into an AI model. Mitigating these risks requires secure training data, model integrity verification, and strict access controls.

You may be the best threat analyst in the world, but are you able to get the dev team to agree on when and what to fix?
OWASP Cornucopia is a mechanism in the form of a card game to assist software development teams in identifying security requirements in Agile development processes.
It works by allowing the team to agree on "what can go wrong", and "What are we going to do about it"?

Threat modeling: It's not finding threats that's the challenge, it's agreeing on when and what to fix.

Organisational Dysfunction of the Day
DORA, the wrong way round
Context: The DORA metrics have become the gold standard for measuring engineering performance. Deployment frequency, lead time for changes, change failure rate, and time to restore service. The four key metrics. Teams build dashboards around them, set quarterly targets, and run improvement initiatives to move the numbers in the right direction. Some teams genuinely improve, while others find the numbers are stubborn or that improvements one quarter quietly reverse the next. Leadership concludes that the teams need more discipline, better tooling, or another round of training. What gets called cargo culting (for lack of a better term) in the industry, copying the visible practices without the underlying conditions, is exactly this pattern.
OST explains: DORA was designed as a research instrument, not as a target system. The metrics are downstream signals of healthy delivery, not the drivers of it. Healthy delivery is when self-managing teams own the whole product, make decisions without escalation, and have tight feedback loops with the people they serve. Take those structural conditions away, and the numbers regress, no matter how many dashboards you build. Treating DORA as a goal in DP1 (bureaucratic) is exactly the goal displacement Goodhart warned about: the moment a measure becomes a target, it stops being a good measure. In DP2, the self-managing-group structure, the same numbers emerge naturally as side effects of work well done. You do not need to chase them. You need to build the conditions that produce them.
Let's Encrypt just stopped the issuance of certificates after an (so far not publicly disclosed) incident:

No prior job experience unfortunately, all those 15 years were mostly personal projects and small-scale stuff for friends. I'm also 26, so I started when I was 11, explaining the no jobs so far. Currently running an entire multi-machine personal cloud infrastructure with a demonstration of all the services I have running at https://status.highenergymagic.net. Three machines, 72 docker containers. One running most of them, one running Mastodon+glitchsocial, one running the uptime monitor. encrypted root on ZFS, alpine linux, gVisor on supported containers, plan to move to Kata. Entirely willing to accept entry-level job placements, no expectation of being paid a lot or anything, just want to be doing something and move the needle a little on my current "being broke" status. Currently using gVisor, docker compose, and kata containers in production, experience with Linux, docker, Net/Open/FreeBSD, Cisco IOS, Juniper Junos, Mikrotik and UniFi, configuring and administering Asterisk, plus extensive experience with IBM AIX and Sun Solaris. #fedihired #infosec #cybersecurity #linux #unix #docker #sre #DevOps #GetFediHired
