Seems the new year bring us some bad surprises in terms of security. There has been some rumors and now turned out to be truth that certain processors are vulnerable to certain attacks. Yes processors. That means that affects a wide variety of Operating Systems. As Microsoft puts it:
Microsoft is aware of a new publicly disclosed class of vulnerabilities referred to as “speculative execution side-channel attacks” that affect many modern processors and operating systems including Intel, AMD, and ARM. Note: this issue will affect other systems such as Android, Chrome, iOS, MacOS, so we advise customers to seek out guidance from those vendors.

I’ve just released the latest version of this script you can find at GitHub. There is just a small fix provided by Lynne Taggart in this release. Basically Microsoft changed the layout of their download page once again so we needed a slightly different logic to pull the MP version and publish date information.
I’ve stumbled on a great article by Brandon Wilson named Demystifying Schannel on which he explains how we can enable verbose logging for Schannel to found out what protocols our machines are using. As I leave and breathe Log Analytics and love to crunch data I thought would be cool example if we can ingest that data into it and show you some cool example with the new query language on transforming data.

As you may have heard Log Analytics has a new query language. When you upgrade solutions are automatically converted to this new query language but I wanted to provide better experience so I’ve updated the Storage Spaces Direct (S2D) solution.

As you are familiar currently OMS has two search portals – the legacy one located in OMS classic Portal and the Analytics one. The Analytics Portal is slowly getting some of the cool features from the legacy Search Portal. One feature that was very handy in it was that TimeGenerated was displayed in the time zone you are accessing it. This is very handy when you have to investigate as it helps you track the events, logs and metrics at your local time. This was missing in the Analytics portal but now it is there and even enhanced.

Yesterday Dave announced that there is a new Azure VM extension that deploys the Service Map Dependency Agent. The example provided was only for PowerShell so it was natural that we need ARM template as well. Continue reading “ARM Templates for Service Map Dependency Agent Deployment”
It took us some time but we’ve managed to update the one and only free OMS book. We had plans to release it earlier but unforeseen things has happened which prevented us to do it earlier. I hope you will understand but you will still enjoy it. The other authors and me put a lot of effort to get it out along with the reviewers.
The new query language of Log Analytics is not included in the book but that should not discourage you as the content is still relevant.
