  title: Sysdig Author Falco Rule and Attach to Policy
  summary: Create a custom Falco rule, then create a policy that references it.
  description: >-
    A detection authoring flow for Sysdig Secure. It creates a custom Falco rule
    from a condition expression, confirms the rule by reading it back, and then
    creates a runtime security policy whose ruleNames reference the new rule so
    the detection is actively enforced. Every step spells out its request inline
    so the flow can be read and executed without opening the underlying OpenAPI
    description.
