Matthew Green, a well respected cryptographer and professor at Johns Hopkins has a great article discussing Secure Computing – Desktops vs Smartphones, iOS vs Android and more..
Most iPhone users do not think very much about security. The iPhone is part of Apple’s closed ecosystem, helping to prevent viruses and malware from wreaking havoc. As the iPhone has grown in popularity, the smartphone has become more of a target by hackers and criminals. It is important that iPhone users immediately become more vigilant about smartphone security. Our tutorial covers the iPhone through iPhone 7 Plus and iOS through iOS 11.
0. Obsolete Hardware
If you have an iPhone or iPad that no longer gets updates, we would recycle it and buy a new one RIGHT away. Keep in mind that iOS 10.3.3 is the first version that fixed a Huge Broadcom Wi-Fi bug. Without that fix, you can get hacked by just having a Wi-Fi signal nearby.
1. iPhone Software Updates
Apple upgrades the iOS software for the iPhone from time to time. Updates include additional functionality as well as security bug fixes. It is important that users apply updates immediately. Before iOS 5 users needed to connect their iPhones to a computer in order to update the smartphone’s software. Needless to say, this was inconvenient and led to many iPhones with obsolete software.
Always update to the latest iOS software available as soon as possible.
