Mobile app security represents the entire process, measures, and actions taken during the app development process and after it in order to ensure system security, data protection, and privacy, and block any form of digital fraud, malware, hacking, or data manipulation
Mobile apps are at our fingertips nowadays and no matter why and how we use them - be it for work, social purposes, personal finance, or just for entertainment, apps are part of our day-to-day activities. Hence, having a secured mobile app is critical so the customers are not at risk with their data.
We asked Dan Ilieș, our Head of Mobile Development at Wolfpack Digital if he has any suggestions on how to ensure your mobile app is secure, no matter if we talk about an Android app or an iOS app, and to provide us with a few tips and tricks.
When we think about obfuscation we consider the process of modifying the code in order to make it impossible to read. And minification allows the developer to reduce the sample code by around 50-60% in size and it is used for both speed optimization and security.
Make sure you store very sensitive information like credentials and certificates in the Keychain (iOS) or Keystore (Android).
similar to web applications’ security, the mobile apps’ APIs should only go through an encrypted connection.
A token can be revoked at any time because a token-based auth will create a unique encoded token to be checked every time a request is made, without storing the data and it has a set lifetime value and can be changed or revoked whenever needed.

2. When a new file is to be saved, a developer can choose from multiple protection options.
And we highly recommend you to use NSFileProtectionComplete or NSFileProtectionCompleteUnlessOpen.
3. Debug Logs Enabling
Unnecessary Debug Logs through the app might print sensitive information and method completion. This is riskier at release builds.
The fix for this would be to use #ifDef DEBUG to enable logs only on debug builds.
3) Add a network security configuration. This allows you to change the configuration without modifying any app code.
