There is no such thing as the myth of a “perfect” green-field deployment. But in real life most of the times there is a just room/resources (e.g. time and money) for patches of green on a big brown-field.
What I really mean.. is that we can’t always keep up with the pace of new technologies and just re-design things from ground up following new trends without understanding or maintaining the legacy design or more importantly meeting the business needs.
Starting from the network and I like to create a basic network diagram will outline at glance things that could potentially limit infrastructure growth or expose it to potential risk that we need to mitigate. Designing , re-designing things well or better is based on getting the requirements right and verify that desired targets are met. To speed up this discovery process we use tools to gather the information we need. Continue reading “Powershell: How to perform Ping Sweep and Reverse-Lookup on a private network”
After a couple of months of being GA (Generally Available) I was in the WSL bandwagon.
I started using Windows Subsystem for Linux (WSL) for a lot of good reasons, especially in my role as System Engineer. I work on different environments and across various operating systems and in my world virtualization and containers are the rule. My tools of trade are Powershell, BaSH and Python on the so having all of them in the same Operating System is really handy.
I attended Meetup events where WSL was presented, I’ve presented a brownbag myself on WSL, and recently as Techsnips Contributor I’ve create a small video on how to install it. So I’ll try in this article to give you a brief introduction.

Microsoft SQL Server is such a popular product that needs no introduction. Like every robust piece of software it requires knowledge and experience to be maintained properly… and that’s is the reason for DBA existence, right? I’m just joking!

Windows Admin Center is a powerful tool that was Generally available after Easter this year and was presented last year under the code-name Project Honolulu.
Windows Admin Center is a lightweight, browser-based GUI platform and toolbox for IT Admins to manage Windows Server and Windows 10. It’s the evolution of a familiar in-box administrative tools, such as Server Manager and Microsoft Management Console (MMC) into a modernized, simplified, integrated, and secure experience.
Windows Admin Center is a natural evolution from the traditional in-box server management tool when you need to connect via RDP to a server or use MMC, RSAT(Remote Server Administration tools) / Server Manager to a Modern web app. The benefit of deploying WAC on your environment is that will help you manage windows machines (server/computers) on premise or Azure cloud VMs.

If not well designed or managed, User and Administrator privilege separation for users/system administrators on a Windows OS can be painful for both sides. Indeed, Windows OS doesn’t have a simple and neat management like a SUDO on Linux OS, but settings need to be tailored with GPO or at least with different users.
Regular user accounts (e.g. Domain Users) should not be a member of the local administrators group for a security point of view.
Using separate users: a standard one and an admin member of the local administrators group is at least a good way to mitigate the risk of potential/malicious/accidental damage to the system. It doesn’t matter if most of the today’s threats can deal with the regular user context.
Nothing new if you’re familiar with the least privilege access, if is something you’ve never think about it… Well, I can use a simple effective analogy for allowing user with local admin rights on their workstation.. it’s like to let them run with the scissors all the time… is it worthy or simply asking for trouble?
