Final answer:
The predefined list of learned processes provided by Cortex XDR is known as the Process Catalog. It is an essential part of the Cortex XDR platform, used for identifying legitimate process activities and minimizing false positives.
Step-by-step explanation:
The list of predefined, learned processes that Cortex XDR provides is called the Process Catalog. Cortex XDR is a cybersecurity platform that uses artificial intelligence to detect, analyze, and respond to threats. The Process Catalog within Cortex XDR includes a collection of known processes that the system uses for comparison to identify any anomalous or potentially harmful process activity on a network or endpoint. This advanced feature is designed to enhance security by recognizing legitimate processes and reducing the number of false positives.
