Install-Module: The term Install-Module is not recognized as the name of cmdlet, function, script file or operable program

While the title of this blog may be a bit exaggeration, the command I’m trying to show here does it’s best to deliver on the promise. What you’re about to witness here is something I’ve worked on for a while now, and it meets my basic needs. If you don’t have SIEM product or products that monitor who does what in Active Directory this command makes it very easy, even for people who don’t have much experience in reading Event Logs. If you’d like to learn about working with Windows Event Logs here’s a great article I wrote recently – PowerShell – Everything you wanted to know about Event Logs and then some.

Reading Event Logs is something that every admin does or at least should do quite often. When writing PowerShell scripts, you often need to read event logs to find out different things across your infrastructure. But now and then it’s quite the opposite. You need to write something to Event Log so it can be recorded for the future. Sure, you can write your information to log files, but since Windows already has a built-in logging system, it may be much easier to write stuff to event log. This allows you to centralize your event logs and processed by specialized tools like SIEM.

I’ve been working last few hours trying to set up my laptop for PowerShell Conference, and one of the tasks is to get my modules up and running. To my surprise on Windows 10 1903 Install-Module thrown a weird error

I have to admit – executing the same command three times and expecting different results is dumb, but I still do it anyway. Fortunately, after trying three times I usually resort to other methods and try to solve the problem I have. Today while trying to trust PowerShellGallery I was greeted with an error.

A few days ago, I was asked to take a look at PowerShell Malware. While I don’t know much about malware, my curiosity didn’t let me skip on this occasion, and I was handed over WindowsPowerShell.evtx file. Ok, that’s not what I expected! I wanted PowerShell .ps1 files that I can read and assess? Well, you play with the cards you were dealt with. What I was handed over was PowerShell Event Log. PowerShell writes whatever you execute, and it thinks it is risky, to Windows PowerShell Operation Event Log.

Microsoft Teams over the last few years have grown into an excellent and flexible tool for both small and big companies. Having the ability to chat with users, store files or have all sorts of data in one place makes it easy and functional. Of course, it has its fair share of issues, but it’s getting better. One of the cool features of Microsoft Teams is being able to send notifications to Microsoft Teams Channels using WebHook Notifications. In the beginning, this feature was pretty limited, but after a few years, it got much better with support for Adaptive Cards, List Cards, Hero Cards, Thumbnail Cards, and Office 365 Connector Card.

In March 2020, Microsoft will release its monthly updates. With those updates, Microsoft will disable insecure LDAP Bindings, which is going to break a lot of your systems (hopefully not). But this was already communicated, and you know all about it, right? If not, you should read those two articles that can help you with understanding what is happening and when.

I’ve been working with Windows Events for a while now. One of the things I did to help me diagnose problems and reporting on Windows Events was to write PSEventViewer to help to parse the logs and write PSWinReporting to help monitor (with use of PSEventViewer) Domain Controllers for events that happen across the domain. It’s handy and I, get those excellent daily reports of what happened while I was gone.

Since my website went down in fire with OVH SBG2, I used this occasion to publish my restored website via Cloudflare. It allows me to have to cache, minimization, and some additional security. One thing that caught my attention while browsing through Cloudflare settings was the Always Online feature based on web.archive.org. Basically, the concept is – whenever the website is down, Cloudflare would go and fetch content from web.archive.org.

A new branch of PSWinReporting is slowly coming, and I thought it would be the best time to have a final article about it with all configuration options available for those that will want to stay using PSWinReporting from Legacy branch. The idea is that you may have it working in your systems and it’s good enough for you. You may not want to change it, and with New Hope, the changes are so big it’s a rewrite.
