What is the primary objective of deploying Microsoft Defender for Identity sensors on domain controllers?

The primary objective of deploying Microsoft Defender for Identity sensors on domain controllers is to detect suspicious activities within the network. These sensors are critical for monitoring user behaviors and activities, particularly those that indicate potential security threats or malicious actions. By analyzing authentication traffic and other signals, Defender for Identity can identify anomalies that might suggest a compromise, such as unusual logon attempts, unauthorized access, and lateral movement by attackers.

This capability is essential for maintaining the security posture of an organization, as domain controllers are central to managing authentication and access within an Active Directory environment. By leveraging these sensors, organizations can gain real-time insights into their security landscape and respond proactively to threats, helping ensure that they can mitigate risks before they escalate into more significant security incidents. This proactive detection plays a vital role in maintaining the integrity and confidentiality of sensitive data within a network.
