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…
Hey there, tech enthusiasts and Active Directory adventurers! Today, let’s talk about something really cool yet often overlooked in the world of Microsoft Active Directory: the AdminSDHolder. Now, you might be thinking, “What’s so special about this AdminSDHolder?” Well, let me tell you, it’s a game-changer in how security permissions are managed in your organization’s digital realm.

Have you ever wondered how to seamlessly connect your on-premises Active Directory with Entra ID? Well, you’re in the right place because today, I’m diving into Entra Connect, formerly known as Azure AD Connect. But hold on tight, because we’re not just talking about the basics; we’re here to make sure you install and configure it like a security pro!

Transitioning between Operating Systems can be a challenge. Many aspects of what you’re used to work differently and you should expect a learning curve.
Well, that was a weird intro for a blog post that has Linux networking in the title! Actually I’m saying goodby to Windows as my primary system…. yes you read that correctly. It’s not that I don’t like the system anymore, it’s the direction Microsoft is taking with AI and the integration into the OS that made me take this decision.

Do you know what really ticks me off? Stuff that doesn’t work as expected. Exactly that happened to me today while I revisited configuring a “Privileged Access Workstation” (PAW). Now a PAW is used to safeguard highly privileged credentials in a domain or cloud environment. In essence it’s a workstation used solely for admin work, all infrastructure management is done from this machine. While talking about configuring a PAW is beyond the scope of this blog post, I do need to point out that “Domain Admins” and equivalent groups should never ever have local admin rights on a PAW, they should be regular users, reducing the risk of credential theft and the obvious malware infection that usually follows.

Introduction
In the realm of Public Key Infrastructure (PKI), where the keys to digital security are exchanged, stored, and safeguarded, cryptographic providers play a pivotal role. These providers are the guardians of cryptographic keys, ensuring the integrity, confidentiality, and authenticity of digital communications. They are the invisible sentinels that underpin the very foundation of trust in the digital world.
Continue readingWith Public Key Infrastructure (PKI), cryptographic hash functions play a pivotal, yet often understated role, operating ceaselessly to secure the integrity and authenticity of digital data as it navigates through contemporary communication networks. To appreciate fully the indispensable role they occupy in PKI, it is essential first to delineate the fundamental principles of hash functions and to understand why they are frequently analogized as the digital fingerprints within the cybersphere.
Continue readingAs I advance into the heart of PKI in this second installment, the focal point shifts towards two pivotal decisions that anyone involved in setting up a PKI must grapple with — choosing the appropriate key length and the cryptographic algorithm. These choices are far from arbitrary, for they are the bedrock of a secure and efficient PKI. A meticulous selection in this stage ensures a fortification capable of withstanding the numerous cyber threats that litter the digital space in this day and age.
Continue readingIn the intricate realm of modern digital communication, trust and security form the bedrock upon which data integrity, confidentiality, and authentication rest. Public Key Infrastructure, commonly referred to as PKI, stands as an elegant solution to the complex challenge of establishing and maintaining this foundation of trust in a digital age.
