Tips to Safeguard iOS Mobile Apps

For anyone who uses digital services, knows that the security of their data is of the utmost importance. And this growing consciousness about safety has resulted in not only users but also organizations to strive for and realize better standards in this regard. The point of concern is that these principles of utmost security apply to all things digital today, especially mobile apps since they are used daily and often gather and store highly sensitive user data. Of course, ensuring the highest standards of safety would mean different sets of measures and guidelines, based on the OS in question.

And among all the OS’ in the market, most people concede that iOS apps are comfortably the safest ones in the world. It is because of the closed system and also owing to the stringent regulations Apple has put in place. However, as you and I know, nothing is perfect, and even iOS mobile apps can prove to be vulnerable to attacks, which, in turn, can be chalked up to security flaws that can be easily prevented. But that doesn’t have to be the case, and to help you make sure that your iOS mobile app is as safe as it can be, here are some tips.

1. Safeguard user data: Perhaps the most obvious mistake a developer can make in this context is storing passwords in UserDefault because here they are saved as a property list file in the app’s ‘Preferences’ folder and that too sans any encryption. What makes this such a problem is that there are ample iOS apps in the market that will allow anyone to effortlessly access the UserDefaults data for any apps that have been downloaded from the App Store. And there’s no telling the kind of damage that can be inflicted when nefarious elements get their hands on this data.

2. App transport security: Some time back, the California-based technology behemoth brought in a novel and highly appreciated feature: App Transport Security, which necessarily compels programmers to make use of only secure network connections. It means that any relationship that an iOS mobile app makes must utilize HTTPS and TLS 1.2. What this does is make sure that the app is unable to communicate with a server with an unprotected connection.

3. SSL pinning is crucial: This method protects against ‘Man in the Middle’ attacks by ensuring that the application communicates with no other server except the one specified by the developer. You can do this by merely saving the designated server’s SSL certificate in the app bundle. But remember that the app will need to be updated every time the server’s SSL key is updated.

We don’t have to tell you just how important it is to undertake every possible measure to protect your iOS mobile app. And never forget that it is an evolving world, so be sure to stay updated with the latest developments in the market before you start working on your custom iPhone app development project.
