Mobile application security testing methodology typically involves several phases to ensure comprehensive coverage of potential security vulnerabilities. Here’s an overview of the general methodology:
- Information Gathering: This initial phase involves collecting information about the mobile application, including the technology stack, purpose of the application, user roles and access levels, potential risks, and other relevant details.
- Threat Modeling: This phase involves identifying the potential attack vectors and security threats that could impact the mobile application. This includes evaluating the application architecture, data flow, and user interactions to identify potential vulnerabilities.
- Testing Environment Setup: This phase involves setting up the testing environment, including the selection of tools and techniques, setting up testing devices, and configuring the testing environment.
- Static Analysis: This phase involves analyzing the application code and configuration files for potential vulnerabilities, including code quality, data storage, network communication, and input validation.
- Dynamic Analysis: This phase involves testing the application under different usage scenarios, including testing on real devices, simulating user interactions, and monitoring the application behavior to identify potential vulnerabilities.
- Penetration Testing: This phase involves simulating an attack on the application to identify potential vulnerabilities and weaknesses. This includes manual and automated testing of the application to evaluate its resilience against various attack vectors.
- Reporting and Remediation: This final phase involves compiling the results of the testing and providing a detailed report of the vulnerabilities discovered. This includes prioritizing the vulnerabilities and providing recommendations for remediation.
It’s worth noting that this methodology is not necessarily linear, and many of the phases may overlap or be revisited multiple times as new information or vulnerabilities are discovered. Additionally, it’s important to continually monitor the mobile application’s security and perform regular testing to ensure that any new vulnerabilities are identified and addressed in a timely manner.

OWASP Top 10 Mobile Security Risks & Mitigations
The OWASP Top 10 Mobile Security Risks is a list of the most common vulnerabilities and risks facing mobile applications. Here are the top 10 mobile security risks, examples and their mitigations:
| OWASP Top 10 Mobile Security Risks | Explanation | Examples | Mitigations |
|---|---|---|---|
| Insecure Data Storage | Sensitive data stored in an insecure manner, making it vulnerable to unauthorized access or theft. | Storing sensitive data such as login credentials, financial data, or personal information in plaintext or weakly encrypted format on the device or in the cloud. | Encryption of sensitive data, secure storage mechanisms, and regular data backups. |
| Insufficient Transport Layer Protection | Data transmitted over unsecured networks, making it vulnerable to interception and tampering. | Sending login credentials or other sensitive data over unencrypted HTTP connections, or using self-signed or expired SSL certificates. | Use of secure transport protocols such as SSL/TLS, certificate pinning, and encryption of data in transit. |
| Insecure Authentication and Authorization | Weak or inadequate authentication mechanisms, making it easier for attackers to gain unauthorized access to the application or sensitive data. | Allowing users to log in with weak or commonly used passwords, or allowing authentication via unsecured channels such as SMS messages. | Use of strong authentication and authorization mechanisms, multi-factor authentication, and regular security audits. |
| Poor Code Quality | Poorly written or structured code, which can introduce vulnerabilities and weaknesses into the application. | Lack of input validation or error handling, buffer overflows, or use of deprecated or insecure functions. | Use of secure coding practices, code reviews, and static and dynamic code analysis tools. |
| Insufficient Cryptography | Weak or inadequate cryptography mechanisms, which can result in data being vulnerable to attacks such as encryption cracking or brute-force attacks. | Use of weak or outdated encryption algorithms, insecure key management practices, or insufficient entropy for generating random numbers. | Use of strong encryption algorithms, key management, and secure random number generation. |
| Insecure Communication | Insecure communication channels between the application and its backend servers, which can allow attackers to intercept and tamper with data. | Lack of certificate validation or certificate pinning, use of self-signed or expired certificates, or use of unencrypted or weakly encrypted communication channels. | Use of secure communication protocols, such as SSL/TLS, and implementation of proper network security controls. |
| Insecure Authorization | Weak or inadequate authorization mechanisms, which can allow attackers to gain access to sensitive data or perform unauthorized actions within the application. | Allowing access to sensitive data or functionality without proper authentication, or not enforcing proper role-based access controls. | Use of role-based access control, least privilege, and regular security audits. |
| Client Code Execution | Vulnerabilities in the client-side code that can be exploited by attackers to execute arbitrary code on the device. | Use of insecure third-party libraries, or not properly validating user input before executing it. | Use of secure coding practices, code reviews, and use of sandboxes to isolate untrusted code. |
| Security Decisions via Untrusted Inputs | Vulnerabilities that arise when applications rely on untrusted inputs for making security decisions, such as authorization or access control. | Allowing user-supplied input to define access controls, or not validating user input before using it to make security decisions. | Use of input validation, data sanitization, and proper error handling. |
| Improper Session Handling | Vulnerabilities that arise when sessions are not properly managed, allowing attackers to hijack user sessions or perform other malicious activities. | Allowing session tokens to be transmitted over unsecured channels or using session tokens that are not sufficiently random or long. | Use of session management |
