I run a small security practice, spend too much time inside terminals, and write here about the infrastructure I build, the systems I take apart, and the projects in between.
I'm Adel — I run a cybersecurity practice out of ciberdefensa.uk, working across red teaming, penetration testing, and incident response for clients who'd rather find their weak points before someone else does.
Outside client work, I'm usually neck-deep in a Linux box somewhere, provisioning cloud infrastructure, or fixing something I broke the night before. This site is where the smaller, more personal version of that work lives.
Red team engagements, penetration testing, and adversary simulation — finding the path an attacker would actually take, not just the checklist.
Hands-on Linux and cloud work — provisioning, hardening, and occasionally rebuilding infrastructure on OCI after I've broken it myself.
Digital forensics, incident response, and zero trust architecture — the unglamorous side of keeping systems standing after something goes wrong.
What happens when you terminate the wrong instance on Oracle Cloud, and the boot volume swap trick that got an Alpine Linux Ampere A1 box back on its feet without starting from zero.
