Border_control vs security control vs random checkpoints?

but “not carrying dangeous items” is not the only reason why “general security checkpoint” might exist. They also might check ID/passports or even some permits

yes, there are different possibilities, and we should distinguish these. Checking id documents and checking for dangerous items can both occur separately. Whether specific permits are required would merit more thought how to do it (or if there are groups of cases).
