Which advantage do query library entries provide in SOC operations?

The query library in Cortex XDR allows analysts and SOC teams to save, manage, and share frequently used or complex XQL queries. A primary advantage of this feature is the ability to standardize threat hunting and investigation procedures. By creating and sharing a set of approved queries for specific threat types or IOCs, a SOC can ensure that all analysts, regardless of experience level, use a consistent and effective methodology. This improves the quality of investigations, facilitates collaboration, and simplifies training for new team members.

B. The query library is for storing and running searches; it does not have the capability to execute response actions like endpoint isolation.
C. Incident scores are modified through alert tuning, scoring rules, or manual analyst actions within the incident view, not through the query library.
D. The query library and dashboards serve different functions; the library is for active investigation, while dashboards provide at-a-glance monitoring and visualization.

It highlights the ability to save and share queries, which directly supports the standardization of investigative processes across a security team. It promotes reuse of effective queries, ensuring consistent hunting practices.
