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 important decisions that anyone involved in setting up a PKI must deal with, choosing the appropriate key length and the cryptographic algorithm. These choices are far from arbitrary, for they are the foundation of a secure and efficient PKI. The selection at this stage will determine the resilience against cyber treats for the foreseeable future.

In the world of system administration and automation, PowerShell has been a trusted companion for managing tasks efficiently across a variety of environments. With the introduction of PowerShell Core 7, the capabilities of PowerShell expanded further by becoming cross-platform, allowing administrators to manage systems regardless of their operating system. Recently, I embarked on a journey to explore the capabilities of PowerShell Core 7’s remoting features, but as often happens in the world of technology, I encountered an unexpected challenge.

In the world of computing, the way we store and manage data is constantly evolving. One such significant change is the transition from the traditional Master Boot Record (MBR) system to the more modern GUID Partition Table (GPT) system. While both serve the critical function of telling our systems where data is stored and how to boot, GPT brings a host of advantages over its predecessor, from supporting larger disk sizes to improved data corruption handling.
