  title: Cortex XSIAM Incident-Driven Asset and XQL Hunt
  summary: List XSIAM incidents, enumerate assets, then run an XQL hunt and poll for results.
  description: >-
    A Cortex XSIAM investigation flow. The workflow lists incidents matching a
    filter, enumerates high-risk assets tracked by XSIAM, launches an XQL query
    against the XSIAM data lake, and polls the results endpoint until the query
    reaches a terminal status. Cortex XSIAM authenticates with a custom
    HMAC-SHA256 scheme requiring the x-xdr-auth-id, x-xdr-nonce, x-xdr-timestamp,
    and x-xdr-hmac-v2 headers, which the calling environment supplies per the
    spec's apiKey security scheme. Every step spells out its request inline so
    the hunt flow can be read and executed without opening the underlying
    OpenAPI description.
