A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team maps its detection lifecycle onto a wall chart, beginning with the stage where the initial SPL logic is created. Which stage is that?
Correct.
Checked against help.splunk.com, August 2026Concept
Naming the stages separately is what lets a team say where a rule is. A detection that has been authored but never tuned is a different risk from one nobody scheduled.
Why D
Splunk documents detection authoring as the first stage, when the initial detection logic or SPL is created.
