Make Mobile App Security a Priority, Not an Afterthought

As most of the companies are relying on digitalization, the need for web and mobile app security skyrockets.

Is your mobile app secure?

This is one of the first and foremost questions as mobile apps are most commonly attacked by hackers. Based on the recent Statistica, 71% of fraud transactions happened through mobile apps and the numbers are increasing with every passing year.

Implementing security audit services for mobile is a smart strategy to protect confidential data of users and maintain loyalty towards your brand. Several mobile app security tools are available that assess your applications with varying degrees of effectiveness. To get the best and verified results, you can also hire top mobile app testing service providers that have expertise in mobile text automation or mobile cloud testing for diverse platforms (Android, iOS, and Windows).

Top-Notch Mobile App Security Practices

  1. Implement Simple & Secure Server -Side Authentication

Authentication is when the user proves his identity. For apps that require server-side implementation, users need to prove their identity to the server before accessing the app services. There are different ways to authenticate a user request in mobile apps. 

  • Session-based Authentication 
  • Token-based Authentication 
  • JSON Web Tokens
  • Shared Secret-based Hash Authentication  

Besides this, multi-factor authentication is gaining a lot of popularity as it involves a combination of both static and dynamic OTP. In some bank-related apps, biometric authentication like fingerprints or retina scans can also be used. 

  • File Encryption

A newer version of Android and iOS app development has file encryption as a default feature. Even if your smartphone is stolen or hacked, the user won’t be able to decrypt the data without using the key, for instance – passcode of the device.

  • Monitoring Data Leakage Points

Data leakage happens when critical mobile applications are stored in a vulnerable location. Mobile data experts always keep an eye on common data leakage points like logging, app background, caching, HTML5 data storage, and browser cookie objects.

  • Use of Threat Modeling

Threat modeling is an approach to deeply understanding whether the problem is solved or not and finding the best solutions to defend against such attacks. A well-informed model helps the development team to know how different OS, platforms, and external APIs store their data. Knowing the points, mobile app testers can implement the best way-outs to reduce inefficiencies.

These are a few common practices that we need to follow to make our app safe. However, there are some specifics about the iOS and Android app security that we need to follow,

Here’s a list of the best android app security practices followed by certified mobile app developers in California to protect mobile apps from cyber-attacks.

How to secure your Android Apps?

  1. Use of Internal Storage for Sensitive Data

Every Android application has an internal storage directory. Store the files in the directory so that none of the particular apps can be accessed by other applications saved on the device. This secures the data at its best.

  • Use HTTPS

Many Android users are using open Wi-Fi and, in such cases, using HTTP instead of HTTPS can make your Android Application vulnerable to malicious hotspots. Hackers can easily alter the content of HTTP traffic.

  • Use Google Cloud Messaging

Instead of using SMS, Google Cloud Messaging (GCM) is popularly used as these communications are authenticated by registration tokens that are regularly refreshed on the client-side.  They are also authenticated using a unique API key on the server-side.

How to secure your iOS Apps?

  1. Storage of Data

To greatly simplify the app’s architecture, the optimum way to store data is in its memory instead of sending the data to the remote server. Keychain is one of the ways to store data securely. 

Use of Keychain – Expert mobile app developers use Keychain to store small amounts of sensitive data that is not frequently accessed. The data which is stored in Keychain is managed by the operating system itself. 

  • Network Security 

Apple is known for its high-end security and privacy policies. Apple has also introduced App Transport Security that enforces third-party mobile apps to send network requests over a secure connection. 


Mobile application security is one of the leading concerns as data residing within the app is at risk when there is mass usage of apps. Leveraging the capabilities of the latest testing tools, you can secure your app against security threats. Building a secure app requires collaboration among different teams like developers, security experts, and marketers. Following the best approaches and high-level expertise, you not only can launch a secure app in the market but also maintain a competitive edge in the market.
