Make sure that your iOS is up to date. This is your primary line of defense against vulnerabilities. I know, I know, there are a lot of them, but that’s the world we live in these days.
It’s also a good idea to keep your apps updated too, but that’s secondary to keeping iOS updated.
Personally, given the number of bugfixes in recent iOS releases, I don’t wait to install them. Sure, there might be bugs like battery issues and such that creep in to iOS releases, but these are, as far as I’m concerned, less of a problem.

Not only does it protect you from badness from getting onto your iPhone but it’ll also speed things up a bit by clearing the RAM.
