No license declared

socfortress/Wazuh-Rules publishes no license, and without an express grant the default is all rights reserved. The query above is synthesized from the rule rather than copied out of it, so you can see what the rule matches on; the rule as written stays upstream.

Not a detection

This rule makes no claim about adversary activity — it asserts configuration, suppresses an alert, or records a policy violation — so it sits at no rung of the pyramid.
