Ever heard of the capolicy.inf file? It’s like a digital instruction manual for a Certificate Authority (CA) server. It pre-configures the CA and has a say in how certificates are set up or renewed. In other words, it’s a behind-the-scenes helper that ensures everything is governed with digital certificates. In this blog post, I’ll break down what this file does and why it matters in plain and simple terms.

Introduction: Why OIDs matter in PKI
When building or managing a Public Key Infrastructure (PKI), precision and uniqueness are not optional, they’re very essential. Don’t be one of many, be your unique self! One key element that reflects this is the Object Identifier (OID). OIDs are globally unique values used to identify everything from certificate policies and application purposes to custom certificate extensions and cryptographic algorithms.
Continue readingA little while ago, I wrote about the shift toward passwordless authentication and why we need to rethink our dependency on traditional passwords. While I’m still convinced that passwordless is the future, and the sooner we get there, the better. At the same time I also see the reality most environments are still dealing with.
Continue readingEarlier this year, I completed my bachelor thesis in Cybersecurity, diving into one of the most exciting developments in the world of authentication (well, that’s my personal opinion anyways), FIDO2 and Passkeys. My research focused on how passwordless authentication can reshape the way we secure digital identities, not only from a technical point of view, but also in terms of user experience, adoption , and the shift in mental models required to move beyond passwords.

Running a GPU-accelerated remote desktop on a Linux virtual machine (VM) in Microsoft Hyper-V can significantly improve performance for graphical applications, GPU intensive workloads, and even remote testing. However, Hyper-V does not support full PCI passthrough like VMware or Proxmox. Instead, it provides Discrete Device Assignment (DDA), which allows passing a GPU directly to a VM.

I usually don’t focus on geopolitics, but the recent uncontrolled developments in cybersecurity, digital infrastructure, and artificial intelligence are too alarming to ignore. The recent shifts in the United States raise critical questions about Europe’s digital future and independence.
Continue readingDid you know that Windows has had a built-in capability to function as a SIEM (Security Information and Event Management) system for years, provided you stay within the Windows ecosystem? This powerful feature, known as Windows Event Forwarding (WEF), allows you to centralize event logs from multiple Windows machines, giving you a comprehensive view of your network’s activities.

I’ll promise to keep this blog post short—well, shorter than usual (hopefully). Last week, I worked on a project involving application allow listing. In the Windows ecosystem, this can be achieved using Windows AppLocker. While AppLocker has been around for quite some time, it’s only recently become available on Windows 11 Professional. Previously, it was an exclusive feature for Enterprise versions.

A long long time ago, in a galaxy far far……. wait, that’s a different universe! But today I do want to talk about something very ancient, RFC2136 that was released in April 1997. This specific RFC describes the process of “Dynamic Updates in the Domain Name System (DNS UPDATE)“.

Today I’ve learned,
That even software and designs from quarter of a century ago still influence the modern Cloud enabled world. In this specific case I’m talking about the PowerBI gateway and how it operates in an on-prem Active Directory environment. Allow me to explain…
