Which process does the Cortex XDR agent identify as triggering an event sequence?

The correct answer is rooted in the concept of causality within incident detection and response. The Cortex XDR agent utilizes the idea of a causality group owner to trace back the events that lead to a security incident. This means that the causality group owner is crucial in identifying the primary source or the initial event that triggered subsequent events in the sequence.

In practical terms, when a series of activities occur on a system, the causality group owner allows cybersecurity analysts to understand the relationship between these activities, determining which events are directly related and which are consequences of a triggering event. This attribute is vital for constructing a coherent timeline and understanding how an adversary operates within a network.

While the other choices relate to processes in cybersecurity, they do not serve the same role in establishing the foundational trigger of event sequences as the causality group owner does. Understanding this specificity enhances the effectiveness of threat detection and mitigation strategies within the Cortex XDR framework.
