Deprecating rules

Rules that have been version locked (added to version.lock.json), which also means they have been added to the detection engine in Kibana, must be properly deprecated.

If a rule was never version locked (not yet pushed to Kibana or still in non-production maturity), the rule can simply be removed with no additional changes, or updated the maturity = "development", which will leave it out of the release package to Kibana.

Steps to properly deprecate a rule

  1. Update the maturity to deprecated
  2. Move the rule file to rules/_deprecated
  3. Add deprecation_date and update updated_date to match

Next time the versions are locked, the rule will be added to the deprecated_rules.json file.

Using the deprecate-rule command

Alternatively, you can run python -m detection_rules dev deprecate-rule <rule-file>, which will perform all the steps
