There are several types of penetration testing for Android apps, each focusing on different aspects of security. These can be broadly categorized as follows:
1. Static Analysis: This method involves examining the application's code without actually executing it. Tools and techniques are used to identify potential vulnerabilities in the source code or compiled binaries. This can reveal issues like insecure coding practices, hardcoded credentials, and potential SQL injection vulnerabilities. It's a cost-effective initial step, but it may not catch all runtime vulnerabilities.
2. Dynamic Analysis: This involves running the application and observing its behavior while interacting with it. This type of testing uncovers runtime vulnerabilities that static analysis might miss. Techniques include fuzzing (inputting random or malformed data to find crashes or unexpected behavior), monitoring network traffic to identify vulnerabilities (e.g., insecure data transmission), and testing for issues like improper authentication and authorization.
3. Black Box Testing: In this approach, the tester has no prior knowledge of the app's internal workings or source code. They treat the app like a regular user, attempting to exploit vulnerabilities through its user interface. This helps identify weaknesses that an actual attacker might discover.
4. White Box Testing: Here, the tester has full access to the app's source code, architecture, and internal workings. This allows for a more comprehensive analysis and identification of vulnerabilities. White box testing is more thorough, but it requires greater resources and expertise.
5. Gray Box Testing: This approach sits between black box and white box testing. The tester has some knowledge of the application, such as its architecture or functionality, but not full access to the source code. It provides a balanced approach to testing that's both efficient and effective.
6. Automated Penetration Testing: This utilizes automated tools and scripts to perform many security tests efficiently, significantly shortening the testing time and reducing labor costs. However, it may not be as thorough as manual testing performed by skilled security professionals.
7. Manual Penetration Testing: This involves skilled security professionals who manually analyze and interact with the application to identify vulnerabilities.
