when you make update the security for iphone

I never make security updates. I’m just another user in this user-to-user technical support forum. iOS security updates are part of the iOS version update, so if your phone is up to date (currently iOS 14.7.1) it has the latest security updates.

Your question doesn't make sense? When Apple releases iOS updates it almost always includes security updates. As long as you are updating your iPhone when new updates are released, you are updating the security on your iPhone.
