You'll want to read this short blog post very carefully because it not only impacts Microsoft, it likely impacts you, as well as the foundational security of 85% of all business and government organizations worldwide, and it does so in a positive way.
A Quick and Short Background
From the White House to the Fortune 1000, Microsoft Active Directory is the very foundation of cyber security at over 85% of organizations worldwide. In fact, it is also the foundation of cyber security of almost every cyber security company worldwide.
Active Directory is the Foundation of Cyber Security Worldwide
The entirety of an organization's building blocks of cyber security, including the user accounts used by the entirety its workforce, as well as the user accounts of all its privileged users, the computer accounts of the entirety of its computers, and the security groups used to provision access to the entirety of its IT resources, are stored, managed and protected in Active Directory.
During the past few years, credential-theft attacks aimed at the compromise of an organization's privileged users (e.g. Domain Admins) have resulted in a substantial number of reported and unreported breaches at numerous organizations worldwide. In response, to help organizations combat the menace of these credential-theft attacks, Microsoft has had to make substantial enhancements to its Windows Operating Systems as well as acquire and introduce a technology called Microsoft ATA.
These enhancements have made it harder for perpetrators to find success with traditional credential-theft attacks, so they've started focusing their efforts on trying to find ways to attack the Active Directory itself, as evidenced by the fact that in the last year alone, we've seen the introduction of Mimikatz DCSync, BloodHound and recently the advent of Active Directory Botnets.
Make no mistake about it. There's no dearth of opportunity to find ways to exploit weaknesses in Active Directory deployments because there exists an ocean of access within Active Directory, and sadly due to an almost total lack of awareness, education, understanding and tooling, organizations have no idea as to exactly what lies within their Active Directory, particularly in regards to privileged access entitlements, and thus today there likely are 1000s of privilege escalation paths in most Active Directory deployments, waiting to be identified and exploited. All that perpetrators seem to lack today is the know-how and the tooling.
Unfortunately, since the cat's out of the bag, perpetrators seem to be learning fast, and building rapidly, so unless organizations act swiftly and decisively to adequately lock-down vast amount of access that currently exists in their foundational Active Directory deployments, sadly the next big wave of cyber breaches could involve compromise of Active Directory deployments.
Clearly, Microsoft Has No Answers
It gives me absolutely no pleasure to share with you that unfortunately, and sadly as always, Microsoft yet again seems to be playing catch-up, and in fact, it has no clue or any real answers, ideas or solutions to help organizations in this vital regard.
Here's Proof - Last week, on September 18, 2017, Microsoft's Advanced Threat Analytics (ATA) Team posted this -
You see, if you understand the subject of Active Directory Security well enough, then you know that Active Directory access control lists (ACLs) today don't just impact organizational security worldwide, they likely impact national and global security!
That said, in that post, the best Microsoft could do is concede that this could be a problem, wonder why organizations might ever need to change AdminSDHolder, falsely assume that it may not impact privileged users, praise a massively inaccurate tool for shedding light on this attack vector, and end by saying - "if you find a path with no obstacles, it probably leads somewhere."
Oh, and the very last thing they tell you that is their nascent ATA technology can detect AD multiple recon methods.
In contrast, here's what they should have said - "We care deeply about cyber security and we understand that left unaddressed, this could pose a serious cyber security risk to our customers. Be rest assured that Microsoft Active Directory is a highly robust and securable technology, and here's exactly how organizations can adequately and reliably identify and lock-down privileged access in their Active Directory deployments, leaving no room for perpetrators to identify and exploit any weaknesses."
The reason I say that should've been the response is because if you know enough about this problem, then you also know that it can actually be completely and sufficiently addressed, and that you don't need to rely on detection as a security measure.
Er, I'm really sorry but you are Microsoft, a US$ 550 Billion corporation, not a kid in college. If the best you can do concerning such a profoundly important cyber security challenge is show how little you seem to know about and understand this problem, and only have detection to offer as a solution, frankly, that's not just disappointing, that's deeply concerning, to say the least.
Further, if this is how little you seem to understand about such a profoundly important cyber security challenge concerning your own technology, I cannot help but wonder how well your customers might actually be protected in your recent Cloud offering.
Fortunately There's Help and Good News For Microsoft
I may appear to be critical of Microsoft, and I do still believe that they ought to at least have educated their customers about this and this huge cyber security challenge, but I also love Microsoft, because I've been (at) Microsoft, so I'm going to help them.
To my former colleagues at Microsoft I say - "Each one of us at Microsoft are passionate, care deeply and always strive to do and be the best we can, and even though I may no longer be at Microsoft, (and I still can't believe how you missed this one), luckily and fortunately for you, we've got this covered, and we're going to help you out."
So, over the next few days, not only am I going to help reduce the almost total lack of awareness, education and understanding that exists at organizations today concerning Active Directory Security, I am also going to help organizations worldwide learn just how they can adequately and swiftly address this massive cyber security challenge before it becomes a huge problem.

You see, each one of these Active Directory security focused objectives can be easily accomplished, but and in order to do so, what is required is the capability to accurately audit effective access in Active Directory. Sadly, let alone possessing this paramount cyber security capability, Microsoft doesn't even seem to have a clue about it.
So, over the next few days, I'll pen the above, and you'll be able to access them at the Active Directory Security Blog.
In fact, this cannot wait, so let us begin with the "actual" insight on Active Directory ACLs that all organizations worldwide must have today -
Together, we can help adequately secure and defend organizations worldwide and deny perpetrators the opportunities and avenues they seek to compromise our foundational Active Directory deployments, because we must and because we can.
