Security has become increasingly crucial as threats to one’s privacy and data continue to evolve. Fortunately, due to technological advancements, we can now implement security measures much more effectively. One area of significant advancement is automated tools and security testing methodologies. 


Techniques like mobile application security testing (MAST) provide frameworks to analyze apps systematically. In addition, platform-specific techniques, like AWS security best practices, help users and developers enhance overall safety. In this article, we will discuss the Importance of MAST, the steps involved in performing mobile application security testing, and the associated challenges.

What Is Mobile Application Security Testing (MAST)

Mobile Application Security Testing (MAST) covers the processes and methods for testing mobile apps. It aims to identify potential security risks, vulnerabilities, bugs, and flaws in mobile apps – issues that can impact an app’s confidentiality, integrity, or availability.

The Importance of MAST

Mobile applications dealing with sensitive data like payments and personal information must strictly comply with various security standards and regulations. App vulnerabilities can compromise the entire smartphone if exploited by hackers. Things like accessing contacts, photos, location data, and online banking credentials risk user privacy. Knowing what vulnerabilities might exist in the code that hackers could exploit is challenging without proper testing. Testing helps identify these issues proactively.

Performing Mobile Application Security Testing

Following are the steps involved in mobile application security testing.

  1. Defining a Goal

The first step is to define the goal of the security testing clearly. What are you trying to achieve, and what areas do you want to focus on? Common aims include checking for security controls, configurations, authentication processes, and data security.

  1. Analyzing for Threats

Once the goal is defined, you must analyze the application to understand potential threats. This involves reviewing the app architecture, resources, external interactions and thinking like a hacker to identify risks. 

  1. Validating Risks

With the identified threats, you need to validate if they are actual vulnerabilities by exploiting them through penetration testing. Different tools can be used to intercept traffic, modify requests, and determine the impact of vulnerabilities. This helps prioritize critical issues.

  1. Remediation

The final step is remediation, where you take the exploitation results and create a list of vulnerabilities sorted by severity. The most critical issues must first be fixed by making appropriate configuration changes, adding security controls, updating code, etc., to harden the application against attacks.

Challenges in Mobile Application Security Testing

Here are the challenges of mobile app security testing.

  1. Oversights and Risks

Connected parts, like external libraries or plugins, may be overlooked when testing focuses only on the app code. This leads to missing potential bugs. Apps have unique functions, data, and connections. So, their security risks are also different. Using the same test checklist for all apps will miss custom problems.

  1. Required Skills and Testing Environments 

Testing mobile apps requires skills in coding, networks, reversing code, and security. It’s challenging to get testers with all these abilities. Even if a team has them, collaboration can be difficult.

The sheer number of phones and tablets out there also poses a problem, as many have different operating systems. Setting up tests on emulators and real devices takes work. Special tools may also be needed to do careful security checks.


In today’s world of advanced cyber security threats, having the right data privacy measures and secure apps is essential. With so many sensitive user details accessible via smartphones, it is critical to identify and address any vulnerabilities that could impact an app. 

Mobile Application Security Testing (MAST) plays a vital role in ensuring the security and privacy of mobile apps. It proactively analyzes threats and designs remediation strategies to ensure that every user has an uncompromised experience.
