What are two reasons incident investigation is needed in Cortex XDR?

Incident investigation is crucial in Cortex XDR for several reasons related to the nature of threats and the functioning of the detection system. One significant reason is that insider threats may not be blocked, and initial malicious activities can go undetected. In many cases, individuals within an organization may exploit their access privileges to carry out harmful actions. These insider threats can evade traditional security measures because they operate under the guise of legitimate user activity. As a result, an incident investigation helps to identify such threats early, enabling security teams to respond effectively before any significant damage occurs.

Additionally, the dynamic and evolving landscape of cybersecurity means that no solution, including Cortex XDR, can guarantee the detection or prevention of every possible attack. Cyber adversaries continuously develop new tactics and techniques that can often bypass existing defenses. Therefore, continuous investigation and monitoring of incidents are necessary to bridge the gaps left by automated systems. This ensures that even if an attack is initially missed, the organization can understand the extent of any potential breaches and enhance its defenses in the future.

Thus, the need for incident investigation in Cortex XDR is rooted in both the potential for undetected insider threats and the understanding that not all attacks can be preemptively blocked. This proactive approach to security is essential for maintaining a
