IMO, you shouldn't do anything special. They're all very low-skill automated attacks. Just design and deploy stuff well, do the basic stuff correctly before you make anything publicly accessible, and don't worry about the noise. If you're doing things properly, none of it will work. Whatever fancy thing anyone suggests to try to reduce the noise likely won't slow down any actual determined human attacker much, and will just cause you more hassle to deploy and maintain.
