Send Check Point Logs to Azure Sentinel (beta)

tom torggler 15 jul 2019

Azure Sentinel is Microsoft’s new, cloud-native security information and event management (SIEM) tool. In my simplistic point-of-view it is a security-focused, machine-learning-driven add-on for Log Analytics (OMS). Today we will be looking into ingesting Check Point Firewall logs into Log Analytics.

ntSystemsPSDrive: a SHiPS drive for the blog

tom torggler 19 apr 2019

Some time ago I wrote a post about Consuming ntSystems with PowerShell. It boils down to this: we have a json-based API that is available via https://ntsystems.it/api/v1/ and returns json elements for posts and pages on the blog. For more information check out the linked post. Then I wanted play around with the SHiPS module for some time and finally got around to doing it this past weekend. Now I’m happy to be sharing another method do consume ntSystems with PowerShell: It can be mounted as PSDrive.

Tunneling SSH through Tor

tom torggler 24 dec 2017

I’ve been using Onion Services aka. Hidden Services to connect to remote machines for some time now. Tor clients can connect to such services through the Tor network, there is no need to know the IP address of the destination machine, likewise there is no need to configure inbound port mappings or firewall rules.

Keeping track of PowerShellCore releases on GitHub

tom torggler 16 apr 2017

I’ve been using PowerShell Core on my MacBook for a while now. As the code is still in its early stages, there’s no way of managing/updating the software one is running, at least none that I would be aware of. I did miss some updates and, as a result, had problems with Visual Studio Code. So I’ve put together a quick function that checks the latest release on GitHub and can conveniently be put into my $PROFILE.

With the following commands, I show you how to stop the Backup for a Virtual Machine and delete the associated Recovery Points.

Introducing: TAK

tom torggler 28 oct 2016

Over the years I did create, find, copy, paste, quite a few lines of PowerShell code. Some of which I’m turning into re-usable functions and collecting in a module, creatively called “Tom’s Admin Kit” or TAK. I hope you find it useful. I try to credit the sources for the stuff that I just copied off of the interwebs, even though I don’t actually remember all of them.

Welcome to our new blog!

tom torggler 5 oct 2016

This site has been running on Azure Web Sites for some time. As we are doing this for fun and are not making any money with the site (see any ad?) we had to use the “Shared” pricing tier which was economically acceptable but from a performance and feature point-of-view, well, not great. We used Cloudflare to get some caching and enable stuff like https and IPv6 for the site and it was OK :) Then came…
