A man-in-the-middle attack, also known as an MitM attack, is a form of eavesdropping in an attempt to steal sensitive data, such as user credentials. These attacks can pose a serious threat to organizations' network security, particularly in environments that use Microsoft Active Directory (AD) for identity management. As Active…
Welcome to AD Security 101, a series that covers the basics of Active Directory (AD) security. This week, we look at primary group IDs and how unnecessary changes to them can complicate account management. Attackers can also exploit primary group IDs to introduce security risks, including privilege escalation, and to…
Resource-based constrained delegation (RBCD) is an Active Directory (AD) security feature that enables administrators to delegate permissions in order to manage resources more securely and with greater control. Introduced in Windows Server 2012 R2 as an enhancement to the traditional Kerberos constrained delegation (KCD), RBCD can help to reduce the…
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…

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…
