Howdy! Apple has released iOS 12 so with a new operating system comes a few security settings that need to be changed. Here's my list of must-haves:
1. USB Restricted Mode should be enabled in order to thwart the low-hanging fruit USB-based hacks
You can find this feature under Settings > Touch ID & Passcode. After you enter your passcode, scroll down and take a look at the USB Accessories option under Allow Access When Locked. On an iPhone X, these options will be under Face ID, instead. While you're there, take a look at my screen shot on the right. I have my phone heavily restricted when locked. It hinders some functionality but it ensures that critical items are not revealed to someone who picks up my phone at random. In particular, if I use my phone for multi-factor authentication, I don't want the code or approval exposed on an unlocked phone.
2. Ensure that updates to iOS are performed automatically
I preach automation... all the time. One of the best ways to ensure that technology stays up to date (therefore secure against newly fixed vulnerabilities) is to allow it to update as soon as new patches are released. By enabling this feature, your iPhone/iPad will always have the latest updates from Apple. This setting is found in Settings > General > Software Update.
3. Supercharge your passcode
Apple has improved iOS passwords in recent releases. For the longest time, the only option was a four digit passcode. Bumping the length to six digits will greatly reduce the possibility of someone using a brute force method to unlock your phone. As a bonus, Apple has made it possible to put in as many digits as you'd like, even alphanumeric, to unlock your phone!
You can find these options in Settings > Touch ID & Passcode. Enter your current passcode then swipe down to Change password. Our recommendation is to set a Custom Numeric Code or Custom Alphanumeric Code. Also while you're there, as a bonus, set Require Passcode to Immediately. This ensures the phone is locked right away, rather than with a delay. It adds a little bit of inconvenience but the protection is well worth it.
4. Turn on Two-Factor Authentication
With millions of passwords for sale on the dark web, two-factor authentication should now be a personal requirement everywhere. If you haven't enabled it already, do so now. This is done under Settings, then tap on your name. Next, go to Password & Security and tap Turn on Two-Factor Authentication. Apple has made it super easy to set up and provides prompts through every step!
