For organizations that use Active Directory (AD), securing domain controllers (DCs) is an essential part of AD security. DCs are critical components of the IT infrastructure. These servers hold sensitive and security-related data, including user account information, authentication credentials, and Group Policy objects (GPOs). Naturally, then, DC security is an…
As cyberattacks targeting Active Directory continue to rise, AD security, identity, and IT teams face mounting pressure to monitor the evolving AD-focused threat landscape. To assist IT professionals in comprehending and preventing attacks that involve AD, the Semperis Research Team publishes a monthly roundup of recent cyberattacks. In this month’s…
Active Directory (AD) migration projects can be challenging and complex. Such projects involve the migration of users, groups, computers, and applications from one AD domain or forest to another. Careful planning and execution can help your migration team complete a successful AD migration, with minimal disruption to end users and…

Securing Active Directory (AD)—the common target in 9 out of 10 cyberattacks—is difficult. Many organizations have legacy AD environments with accumulated misconfigurations that attackers love to exploit. And although 90% of organizations worldwide use AD as their primary identity store, Gartner research shows that only 33% have any sort of…
Before we dive into technical tips that I mentioned in my previous post, I want to raise an important point. If you're relying solely on security information and event management (SIEM) tools for Active Directory (AD) security monitoring—especially against potential cybersecurity attacks—you might not be getting a complete picture of…
While playing with Kerberos tickets, I discovered an issue that allowed me to authenticate to other domains within an Active Directory (AD) forest across external non-transitive trusts. This means that there is in fact no such thing as a “non-transitive trust.” The term is at best misleading and offers systems…
