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.

The World's Best Active Directory ACL / Security Permissions Audit Tool

Folks,

Hope your 2017's off to a great start. As I had indicated a few days ago, starting January 26th I'll be sharing some valuable insights on Active Directory Security; until then just wanted to get some very basic stuff out of the way; this one being the 5th.

Active Directory ACL / Security Permissions Audit - A Basic Need

Today virtually every organization that operates on Microsoft's Active Directory has a basic and essential need to be able to easily view, analyze and audit Active Directory ACLs (Access Control Lists) because Active Directory permissions ultimately protect virtually all of the organization's IT resources. A few examples of such basic Active Directory ACL audit needs include -


  1. Who security permissions/rights does a specific user/group have in a specific Active Directory object's ACL?
  2. Who has a specific Active Directory security permission allowed in the ACL of a specific Active Directory object?
  3. Which ACEs (access control entries) grant a specific Active Directory security permission to various security principals?
  4. Which ACEs explicitly deny a specific Active Directory security permission in an object's ACL?
  5. Which ACEs explicitly grant a specific Active Directory security permission to a specific user or group in an object's ACL?

Now, let me be the first to tell you that if you truly know Active Directory Security, then you know that it is not "Who has what permissions" but "Who has what effective permissions" that matters (and the difference is colossal and could be the difference between security and compromise), but for now let's just play along and assume that this is what organizations need to audit.

To fulfill their ACL analysis needs, IT admins worldwide use numerous means, such as writing in-house LDAP/ PowerShell scripts, using free MS tools like dsacls, acldiag, LDP etc., or relying on some 3rd party audit tools many of which aren't reliable.

In doing so, here are some issues/challenges they could run into -
  1. In-house scripts are prone to human-error, need to be maintained and could be maliciously modified by someone.
  2. The use of PowerShell, and/or utilities like LDP requires a certain level of technical Active Directory expertise.
  3. Many 3rd party tools, whilst inexpensive, may or may not always be sufficiently trustworthy (e.g. built in Russia etc.)

In our experience, we found that what is ideally needed is a dedicated and reliable (tamper-proof) Active Directory ACL analysis, viewing and dump tool that can help easily & trustworthily fulfill all Active Directory ACL/permissions audit needs.

So we built possibly the world's best (most advanced) Active Directory ACL Viewer and Exporter that could help IT admins, analysts, auditors and other stakeholders easily and trustworthily fulfill their basic Active Directory ACL/permissions audit needs.
