What I Wish I Saw When Attacking Your Directory
Active Directory has long been a primary target for attackers-and for good reason. As a former AD architect turned pen tester, Eric has seen the same problems over and over again when it comes to securing AD. Gaining complete control over a network should be a difficult and challenging endeavor but, unfortunately, it often only takes a few steps. Eric has a secret: some simple changes would completely turn that around. In this talk, he will share a small list of AD defenses that should be in every environment. Not only would they dramatically slow down attackers, disrupt lateral movement, and increase your detection chances; but they are all native options in Windows and AD. Let’s take a hacker’s playground and make it their nightmare!
