Unmonitored Active Directory Certificate Services (AD CS) servers pose a significant risk to your organization’s identity infrastructure. AD CS, the backbone of certificate issuance and trust, is a high-value target for attackers aiming to escalate privileges or forge credentials. Without proper monitoring, attackers can exploit these servers to issue unauthorized certificates, enabling stealthy lateral movement and persistent access. Deploy Microsoft Defender for Identity version 2.0 sensors on all AD CS servers to mitigate this risk. These sensors provide real-time visibility into suspicious activity, detect advanced threats, and generate actionable alerts based on security events and network behavior.

Unmonitored Active Directory Federation Services (ADFS) servers are a significant security risk to organizations. ADFS controls access to both cloud and on-premises resources as the gateway for federated authentication and single sign-on. If attackers compromise an ADFS server, they can issue forged tokens and impersonate any user, including privileged accounts. Such attacks might bypass multi-factor authentication (MFA), conditional access, and other downstream security controls, making them particularly dangerous. Without proper monitoring, suspicious activity on ADFS servers might go undetected for extended periods. Deploying Microsoft Defender for Identity version 2.0 sensors on ADFS servers is essential. These sensors enable real-time detection of suspicious behavior and help prevent token forgery, abuse of trust relationships, and stealthy lateral movement within the environment.

These servers operate at the intersection of on-premises and cloud identity, making them a prime target for privilege escalation and stealthy persistence. Without monitoring, such attacks can go undetected. Deploying Microsoft Defender for Identity version 2.0 sensors on Microsoft Entra Connect servers is critical. These sensors help detect suspicious activity in real time, protect the integrity of your hybrid identity bridge, and prevent full-domain compromise from a single point of failure.
