How to put security protections on my Apple iPhone 6s

First, make sure you can locate it if it's lost or stolen. Activate the Find My iPhone app.

Beyond that, your iOS (phone operating system) already has antivirus and anti-malware protections as part of the iOS.

For your physical protection, get a good-quality case and screen protector. A lot of folks swear by the LifeProof and Incipio brands.

To keep others out of your phone, activate the Touch ID and/or facial recognition.

Finally, keep track of your phone. Don't drop it or go swimming with it, don't leave it on the table while you go to a restroom, and don't leave it in a hot car.

No, you don't. iPhones cannot get viruses/malware unless jailbroken.
