Testing
Security is a hot topic in the digital world and with the exponential growth of mobile apps available, delivering a 
perfectly working, highly secure app is crucial to user retention. It is important to let users know 
what information is being collected, as well as how and why companies are collecting it. Apps should only collect 
absolutely necessary data. This blog post will provide an overview of mobile applications' security challenges as 
well as the requirements to overcome them and protect users’ data in the meantime.
What Is Security Testing?
Mobile application security testing can help ensure there aren’t any loopholes in the software that may cause 
data loss. The sets of tests are meant to attack the app to identify possible threats and vulnerabilities that would 
allow external persons or systems to access private information stored on the mobile device.
Why Is It Important To Do Security Testing?
We store a lot of information on our devices. Leakage of that information could cause serious damage to the 
devices and users. Encrypting your data can be a possible solution, but it’s not bulletproof - everything that can 
be encrypted can also be decrypted.
Challenges Of Mobile Application Security Testing
1. Integrations with other apps
Usually, testers perform integration testing to see if an app interacts with other apps (e.g. share an article you are 
reading on a browser app to Facebook). What to look out for here is that the information that moves from one 
app to another moves from app A to app B without leaking anywhere else. The best solution is to protect and 
isolate data.
2. Unsecured communications
Many messaging and VoIP calling apps started to encrypt messages, but most of them encrypt messages just 
between users. The app provider company and prying third parties can still read them. The best option here 
would be end-to-end encryption, where only users with a certain key can decrypt the message. WhatsApp is a 
good example of messaging and communication encryption, even if it’s not perfect.
