Active Directory is 25 years old - are you still managing it like it's 1999? Richard talks to Liz Tesch about her excellent blog post on the subject and the challenge many sysadmins have with Active Directory today. Liz talks about how WAN bandwidth was a concern in the early 2000s, so we organized Active Directory into Organizational Units to minimize the amount of AD traffic over the WAN - today, that is irrelevant. The challenge today is ensuring AD is not a vector for blackhats to attack the organization. Raising your functional level and utilizing some great free tools (check the links in the show notes) are all you need to use Active Directory like it's 2025!LinksActive Directory is 25 Years Old.

Are some of your team members starting to hate PowerShell? Richard talks to Barbara Forbes about her experiences with teams frustrated by PowerShell. Barbara talks about overcomplicating PowerShell scripts—the kind the most senior folks can create but no one else can maintain. Eventually, nobody will want to touch those scripts. Then there is the question of business value—does everything need to be automated? And by how much? Often, the appropriate solution solves 80% of the cases; the other 20% are best done by hand because the cost and complexity of the last 20% are too high. Focus on the return on investment for the business, and you'll keep the love of PowerShell alive! LinksPowerShellPester TestingGitHub CopilotBicepRecorded February 24, 2025

How can Security Copilot help you secure your applications? Richard talks to Ari Schorr about assessing application risk with Microsoft Security Copilot - a new feature in preview in Security Copilot that focuses on application roles and entities. Ari talks about the sheer array of resources that applications depend on, and the many security risks that exist in that space - how do you even get started on the problem? Security Copilot helps to sort through potential risks and help a sysadmin focus in on the most significant risks, especially the low-hanging fruit weak authentication and unused resources. The conversation also explores some of the future potential of a tool like this to detect supply chain attacks, find ways to strengthen and simplify applications so their attack surface is smaller.

What can GitHub Copilot do for SysAdmins in 2025? Richard talks to Jessica Deen from GitHub about her experiences using Copilot for her work. Jessica talks about Copilot being the first stop for most tasks - describing the task to Copilot helps you think through the problem, and often the tool can generate code or information to get that task done fast.

How do you write better PowerShell? Richard talks to Jeff Hicks about his latest book, Behind the PowerShell Pipeline, and his efforts to promote writing PowerShell scripts that are easy to understand, use, and maintain! Jeff talks about how making a script work is not enough anymore - you can use GitHub Copilot. The goal is to make the output as usable as possible, whether that is consistent output that is pipe-able or using color coding and column controls to make the results as actionable as possible. This is especially true as your team grows and more than one person works on scripts. Now, you'll want testing and source control, too!LinksPowerShell 7.5Behind the PowerShell PipelineGitHub CopilotPesterPowerShell SummitRecorded February 20, 2025

Are you using strong certificate mapping in Active Directory? Richard Hicks returns to the show to talk about the impacts of KB5015754, issued way back in 2022, and how it turned into an enforcement event on February 11, 2025 that might have caused some serious problems for folks trying to authenticate to Active Directory. For most sites, the upgrade to strong certificates was pretty much automatic. But if you're using Intune SCEP, you needed to do some configuration - and if that was missed, there is trouble. There are workarounds for now, but come September 2025, enforcement will be mandatory and everything gets harder, so it's worth looking into it now!LinksKB5015754: Certificate-based Authentication Changes on Windows Domain ControllersRichard's Blog Post on Strong Certificate Mapping EnforcementActive Directory Certificate ServicesCreate and Assign SCEP Certificate Profiles in IntuneHeartbleedRecorded February 17, 2025
