After months and months of hard work, endless hours of coding, and incredible efforts, you’ve finally built your dream game app. You’re delighted with your final product and hoping to monetise your app to your targeted group audience.

But wait!

Have you checked your app? Is it safe and secured enough to not get hacked by any individual with a malicious attack?

Today, mobile app safety and security hold utmost importance just like its usefulness to the end-audience. Forget about earning dollars with millions of app downloads and installation if your application is found inviting hackers and attackers to breach its security measures.

This guide solely focuses on a specific region worldwide, Belgium, one of the highest cyberattacks suffering country, especially attacks, are more common on mobile devices. However, the mobile app developers in Belgium are equipped with top-notch tech vulnerability to leverage in their app code that secures and hard-protected to get it attacked by any pro-attacker.

Let’s get started with a few steps that are inevitable for mobile app developers to follow to get a hard-rocked coding system.

1. Design Security into the mobile app

The first step to build a highly secured mobile app is to consider security as the first and foremost aspect during the designing phase. Relying too much on the client’s device data can open doors for various mobile apps’ attacks.

Secondly, developers should understand the product and focus on ways to secure the code of their product to avoid the vulnerability that affects both website and mobile apps in the name of cross-scripting flaws.

Considering these points at the beginning of the project can help developers secure proof of their mobile apps comfortably and cheaply.

2. Do not forget to test each product iteration

Once a highly secure design is created, developers should keep more of an eye on the code and ensure that it doesn’t result in vulnerability. Undergoing frequent code scanning in each iteration can help detect the openness and the design flaws that peep inside the application.

Whenever a company makes its tools, they follow a secure design lifecycle that involves a lot of testing. So, as a part of testing, mobile app developers need to make sure that their app undergoes testing and monitors network traffic. Sometimes, coding libraries and advertising frameworks may perform certain insecure activities that can be identified through monitoring.

3. Device data storage encryption

Poor data encryption is one of the primary security concerns for the threat caused by mobile apps. Historically, mobile apps have faced huge issues with protecting data because they do not encrypt server connections and not store authentic credentials.

To safeguard your mobile application by not compromising your credentials and data, programmers need to protect their data with strong encryption so that attackers fail to gain control over it.

4. Identify and manage third-party libraries

To safeguard your system from getting attacked, developers need to implement a system that performs a regular check for updates in the third-party library so that the code remains updated with the latest versions. If you fail to do so, it could leave a security loophole in the product that the attackers can easily exploit.

5. Minimize the attack surface area

This is something that every developer should focus on in every app development. Instead of using a broad framework, mobile app developers should minimise the app functionality by adding the capabilities needed to reduce the opportunities to get attacked. 

This concept is formerly known as minimising the surface area of application for getting attacked.

Instead of trusting multiple certificates, mobile app development companies can hardcore trusted certificates into the software, further known as certificate pinning. Using this technique will eliminate the vulnerability of getting attacked.

6. Reverse code engineering

Now mobile app developers can incorporate numerous techniques to harden the apps from getting attacked by reverse-engineering the code. Code obfuscation that turns or confuses the code from getting understood will raise the bars and make it difficult for hackers to hack. 

Which are the top two mobile app security testing tools in 2021?

Enlisted below are the two mobile app security testing tools used worldwide:

1. WhiteHat Security

Being recognised by Gartner as a leader in security testing, it provides services such as web app security testing, mobile app security testing, computer-based training solution, and more.


It is a cloud-based security platform that supports Android and iOS.

A clear and concise description of loopholes and security vulnerabilities along with a solution.

It can be integrated with bug tracking tools, ALM tools, and CI servers.

Testing is performed on the actual device after installation. It does not use an emulator.

Automated static and dynamic mobile app testing.


It’s a USA based software company that provides the ultimate solution for mobile app security testing. It uses static and dynamic tools to offer a customised mobile app security testing suite.


· It combines multiple tools to get the ultimate solution for mobile app security testing.

· It focuses on delivering defect-free software into the production environment.

· Synopsys helps improve quality and user experience and thus reduce overall costs.

· It tests vulnerabilities using embedded software and eliminates security vulnerabilities from server-side applications and APIs.

Wrapping up:

In the end, secure mobile apps come down to education and resolving loopholes. 

Developers need to understand how to build a secure app what common vulnerabilities and security weaknesses can shake the application. Only by incorporating security measures in the development process through a fast design review of third-party libraries or reverse code engineering will help developers to build apps that resist them instead of getting attacked.
