You can then activate whichever rules you want. If you delete any of the prebuilt rules, a button appears that enables reloading all the deleted ones.

Apart from the Elastic Endpoint rule, prebuilt rules are not activated by default. If you want to modify a prebuilt rule, you must first duplicate it and then make your changes to the duplicated rule.

All Elastic prebuilt rules are tagged with the word Elastic.
