Mobile Application Security Testing: Key Challenges to Consider!

Security has always been a crucial topic in the digital world. With the exponential growth in the mobile app industry, delivering a high performing, highly secure app becomes essential for user retention. The users expect from a company that whatever information it collects from them is transparent, and also it mentions the reason for storing that data.

Due to this, business owners have been particular lately when it comes to mobile app security testing. That’s why user data protection has been the first demand put forward for a mobile app development company developing an app for businesses.

This blog post will introduce you to the security challenges faced by mobile applications in day-to-day life. So, let’s begin this blog.

What is Mobile App Security Testing?

Mobile app security testing is a process that ensures your mobile app does not contain any loopholes in terms of data security. It checks the application software and identifies the drawbacks that might lead to losing users’ private information.

The process includes a set of various tests that attack the mobile apps to find the possible vulnerabilities and threats. These vulnerabilities would enable external and unwanted persons to access private data stored on smart devices. Therefore, it is crucial to perform mobile app security testing to ensure your app is free from such threats.

Why is Mobile App Security Testing Important?

Today, we store almost everything on our devices, be it our personal pictures, videos, or other document files. It is a lot of information that can be really sensitive and losing it can be damaging. Although encryption is an option to secure your private data, it is not bulletproof.

Moreover, you should note that hackers can decrypt encrypted data too.

Challenges of Mobile App Security Testing

Integration with Other Apps

Generally, testers integrate one app with the other to check whether they interact well or not. However, when integration of applications takes place, the information of one app moves to another app without getting leaked anywhere in between. In that case, it would be challenging to perform mobile app security testing.

If the environment and structure of both the apps and devices are inconsistent, security breaches can occur. Performing mobile app security testing can help you find this.

Unsecured Communications

There are many messaging and VoIP calling apps that encrypt messages but just between the users. The app provider company and the integrated third-party companies still have access to look and read them. The best mobile app security testing method can be end-to-end encryption to avoid this. It allows the users with a specific key to decrypt the end-to-end encrypted message. WhatsApp is one such company that uses end-to-end encryption technology for messaging and communication.

Installation of Malware Through Security Breaches

One of the worst things about security breaches is that it steals your data and causes malware to get installed on your device. Malware is malicious software that can come into a downloadable file and install itself. This software can cause harm to a smart device or its OS and can stream the information online on the server.

Integration and Utilization of Various Authentication Procedures

Authentication procedures add an extra layer of security to users’ private information. However, it has two potential issues. First is, you might require a login to use data stored on a remote server. The system then verifies login credentials sent from your devices, which needs to be encrypted. 


Secondly, to sign in to an application, The server must confirm or decline your entered credentials by connecting to your device. Hence, the formed connection should be a secure one.


However, when you try to log in through other methods, like via social media handles, such as Facebook or Twitter, hackers might get access to those login credentials. Along with that, they can also get full access to all the connected services. For instance, when you log in to your app through Gmail, hackers not only gain access to your app but to your Gmail account as well.

Testing Hidden Parts of the Application

Vulnerabilities can occur anytime, anywhere. The most common source is the code itself. If you do not take care of the easily prone parameters, you serve the hackers your users data on a silver platter. 


For example, SQL shortcodes used for text boxes, drop-down menus, radio buttons, and other UI precoded elements are easily vulnerable to injection attacks. Hidden post parameters welcome the intruders to post undesirable content to your app that drives wrong information to your users.

Final Thoughts

Security Testing is equally important as the features, designing and performance of an application are. You can avoid most vulnerabilities if you take the security practices seriously and observe the loopholes timely. For this, you need a well-experienced mobile app development agency that knows all about manual and automated security testing. The earlier you identify the security flaws in your app, the better it will be for your mobile business application.
