Today Active Directory Security has become mission-critical to organizational security worldwide and thus mission-critical to Cyber Security worldwide. On this blog, former Microsoft Program Manager for Active Directory Security, and today, CEO of Paramount Defenses, shares valuable technical insights on Active Directory Security.

Looking Back at 2017 - An Eventful Year for Active Directory Security

Folks,

As we get ready to bid farewell to 2017, it may be fitting to recap notable happenings in Active Directory Security this year.

This appears to have been the year in which the mainstream Cyber Security community finally seems to have realized just how important and in fact paramount Active Directory Security is to cyber security worldwide, in that it appears that they may have finally realized that Active Directory is the very heart and foundation of privileged access at 85% of organizations worldwide!


I say so only because it appears to have been in this year that the following terms seem to have become mainstream cyber security buzzwords worldwide - Privileged User, Privileged Access, Domain Admins, Enterprise Admins, Mimikatz DCSync, AdminSDHolder, Active Directory ACLs, Active Directory Privilege Escalation, Sneaky Persistence in Active Directory, Stealthy Admins in Active Directory, Shadow Admins in Active Directory, Domain Controllers, Active Directory Botnets, etc. etc.



Top-10 Notable Active Directory Security Events of 2017

Here are the Top-10 most notable events in Active Directory Security this year -


  1. Since the beginning on the year, i.e. January 01, 2017, Mimikatz DCSync, an incredibly and dangerously powerful tool built by Benjamin Delpy, that can be used to instantly compromise the credentials of all Active Directory domain user accounts in an organization, including those of all privileged user accounts, has been gaining immense popularity, and appears to have become a must-have tool in every hacker, perpetrator and cyber security penetration-tester's arsenal.

  2. On May 15, 2017, the developers of BloodHound introduced version 1.3, with the objective of enhancing its ability to find privilege escalation paths in Active Directory that could help find out "Who can become Domain Admin?"  From that point on, Bloodhound, which is massively inaccurate, seems to have started becoming very popular in the hacking community.

  3. On June 08, 2017, CyberArk a Billion+ $ cyber-security company, and the self-proclaimed leader in Privileged Account Security, introduced the concept of Shadow Admins in Active Directory, as well as released a (massively inaccurate) tool called ACLight to help organizations identify all such Shadow Admins in Active Directory deployments worldwide.

  4. On June 14, 2017, Sean Metcalf, an Active Directory security enthusiast penned an entry-level post "Scanning for Active Directory Privileges and Privileged Accounts" citing that Active Directory Recon is the new hotness since attackers, Red Teamers and penetration testers have realized that control of Active Directory provides power over the organization!

  5. On July 11, 2017, Preempt, a Cyber Security announced that they had found a vulnerability in Microsoft's implementation of LDAP-S that permits the enactment of an NTLM relay attack, and in effect could allow an individual to effectively impersonate a(n already) privileged user and enact certain LDAP operations to gain privileged access. 

  6. On July 26, 2017, the developers of (massively inaccurate) BloodHound gave a presentation titled An ACE Up the Sleeve - Designing Active Directory DACL Backdoors at the famed Black Hat Conference USA 2017. This presentation at Black Hat likely played a big role in bringing Active Directory Security to the forefront of mainstream Cyber Security.

  7. Also on July 26, 2017, a second presentation on Active Directory Security at the Black Hat Conference titled The Active Directory Botnet introduced the world to a new attack technique that exploits the default access granted to all Active Directory users, to setup command and control servers within organizations worldwide. This too made waves.

  8. On September 18, 2017, Microsoft's Advanced Threat Analytics (ATA) Team penned a detailed and insightful blog post titled Active Directory Access Control List - Attacks and Defense, citing that recently there has been a lot of attention regarding the use of Active Directory ACLs for privilege escalation in Active Directory environments. Unfortunately, in doing so Microsoft inadvertently ended up revealing just how little its ATA team seems to know about the subject.

  9. On December 12, 2017, Preempt, a Cyber Security announced that they had found a flaw in Microsoft's Azure Active Directory Connect software that could allow Stealthy Admins to gain full domain control. They also suggested that organizations worldwide use their (massively inaccurate) tooling to find these Stealthy Admins in Active Directory.

  10. From January 26, 2017 through December 27, 2017, Paramount Defenses' CEO conducted Active Directory Security School for Microsoft, so that in turn Microsoft could help not just every entity mentioned in points 1- 9 above, but the whole world realize that in fact the key and the only correct way to mitigate each one of the security risks and challenges identified in points 1 - 9  above, lies in Active Directory Effective Permissions and Active Directory Effective Access.





Helping Defend Microsoft's Global Customer Base
( i.e. 85% of Business and Govt. Organizations Worldwide )

Folks, since January 01, 2017, both, as former Microsoft Program Manager for Active Directory Security and as the CEO of Paramount Defenses, I've penned 50+ insightful blog posts to help educate thousands of organizations worldwide about...


...not just the paramount importance of Active Directory Security to their foundational security, but also about how to correctly secure and defend their foundational Active Directory from every cyber security risk/challenge covered in points 1- 9 above.

This year, I ( / we) ...

  1. conducted 30-days of advanced Active Directory Security School for the $ 650+ Billion Microsoft Corporation

    Introduction, How Well Does Microsoft Understand Cyber Security, The Importance of Active Directory Security, The Impact of an Active Directory Security Breach, The Active Directory Attack Surface, The Top-5 Security Risks to Active Directory, Active Directory Privilege Escalation, An Ocean of Access Privileges, AdminSDHolder, Active Directory ACLs - Attack and Defense (Actual),  Active Directory Effective Permissions, and so many more ...


  2. showed thousands of organizations worldwide How to Render Mimikatz DCSync Useless in their Active Directory

  3. helped millions of pros (like Mr. Metcalf) worldwide learn How to Correctly Identify Privileged Users in Active Directory

  4. helped the developers of BloodHound understand How to Easily Identify Sneaky Persistence in Active Directory

  5. helped Microsoft's ATA Team learn advanced stuff About Active Directory ACLs - Actual Attack and Defense

  6. showed CyberArk, trusted by 50% of Fortune 100 CISOs, How to Correctly Identify Shadow Admins in Active Directory

  7. helped cyber security startup Preempt's experts learn How to Correctly Identify Stealthy Admins in Active Directory

  8. helped the presenters of The Active Directory Botnet learn How to Easily Solve the Problem of Active Directory Botnets

  9. helped millions of cyber security folks worldwide understand and illustrate Active Directory Privilege Escalation

  10. Most importantly, I helped thousands of organizations worldwide, including Microsoft, understand the paramount importance of Active Directory Effective Permissions and Active Directory Effective Access to Active Directory Security


In fact, we're not just providing guidance, we're uniquely empowering organizations worldwide to easily solve these challenges.





Summary

All in all, its been quite an eventful year for Active Directory Security (, and one that I saw coming over ten years ago.)

In 2017, attackers, pen-testers and defenders finally seem to have realized the importance of Active Directory Security.


Perhaps, in 2018, they'll realize that the key to Active Directory Security lies in being able to accurately determine this.

Best wishes,
Sanjay.
