Definition
A query is a request made to a data system—such as a database or log platform—to retrieve, filter, or manipulate data. In security operations, queries are used to search through logs, identify patterns, and extract relevant information for analysis. Queries are typically written in a structured language such as SQL or Kusto Query Language (KQL), allowing analysts to specify exactly what data they want and how it should be processed.
