I am happy to announce that the book I have been writing with my co-worker, Richard Diver, (and I have no idea how he got top billing 😉 ) is almost finished and will be released soon. It is an introduction to Azure Sentinel and covers all the topics from planning your Log Analytics workspace all the way to the tasks you can take to perform your Threat Hunting.
You can find it on Amazon here: https://www.amazon.com/Learn-Azure-Sentinel-artificial-intelligence-ebook/dp/B0859C7L1G/ref=sr_1_2?keywords=azure+sentinel&qid=1583758038&sr=8-2
or on the PackT website here: https://www.packtpub.com/security/learn-azure-sentinel
I will note that I really don’t care where you get the book but if you want a hard printed copy, you can get that and the E-book from PackT for the same price as the paper book from Amazon.
