White box penetration testing is an approach to security testing method, conducted to find vulnerabilities present in the software or application of an organization. It is one of the three types of penetration testing, apart from black box and grey box pentesting. In penetration testing, the testers mimic real-world attacks to determine weak points in the application that hackers could exploit.
In this article, we will discuss white box penetration testing, its techniques, and how it is helpful for businesses.
What is White Box Penetration Testing
Also known as transparent or clear box testing, white box penetration testing is where the penetration testers have all the information about the tested environment. They are given the entire access to the target area, including source code, access to documentation, credentials, and multiple accounts with different access levels.
A white-box penetration test is frequently employed to assess critical components of a system, particularly by companies involved in software development or utilizing multiple applications. This method evaluates a system's defenses to determine its ability to withstand various cyberattacks.
Why Businesses need White Box Penetration Testing
Businesses benefit from white box penetration testing as it helps them avoid vulnerabilities that could be exploited by hackers or cyber attackers. Penetration testing is crucial for enhancing overall security and ensuring compliance with industry standards.
Benefits of White Box Penetration Testing
1.???? Comprehensive Analysis: Provides a thorough examination of both internal and external vulnerabilities, including insights into the internal workings that attackers typically lack.
2.???? Early Vulnerability Detection: Integration into the initial development stages allows for the detection of vulnerabilities before software deployment or user access.
3.???? Wide Coverage: Identifies vulnerabilities in areas inaccessible to Black Box testing, such as the app's source code, design, and business logic.
4.???? Precise Vulnerability Identification: Leveraging detailed system knowledge, testers accurately pinpoint specific vulnerabilities and potential security gaps in code logic.
Black Box, Grey Box, and White Box Penetration Testing Differences
Black Box Pentest
2. Doesn't require programming knowledge.
3. The tester, developer, and end-user can participate.
4. Least time-consuming security testing method.
5. Not suitable for algorithm testing.
White Box Pentest
2. Requires high programming knowledge.
3. Only the tester and developer can participate.
4. Most time-consuming security testing method.
5. Suitable and recommended for algorithm testing.
Grey Box Pentest
2. Requires limited programming knowledge.
3. The tester, developer, and end-user can participate.
4. Less time-consuming than white box pentesting.
5. Not considered for algorithm testing.
White Box Penetration Testing Techniques
White box penetration testing techniques involve examining the source code (internal structure) to uncover vulnerabilities that could expose the software to cyber threats. Here are the three main types:
Path Coverage:
This technique tests all possible execution paths within the software. It ensures that every path, representing a set of instructions followed during execution, is tested for vulnerabilities. It's particularly effective for complex structures.
Statement Coverage:
Statement coverage focuses on checking each functionality of the application at least once. It identifies unused or missing statements and eliminates leftover dead code.

Branch Coverage:
Branch coverage in white box penetration testing evaluates different execution paths, particularly after decision statements like "if" statements. It ensures all possible branches in the codebase are tested and that no branch leads to abnormal behavior in the application. This technique verifies that every line of code is executed at least once.
White Box Penetration Testing Process
Source Code Review:
1.???? Examine source code thoroughly to understand internal structure and functionality.
2.???? Design test cases to find security weaknesses.
Select Testing Areas:
1.???? Choose specific areas for testing based on software understanding.
2.???? Focus on smaller areas for comprehensive coverage.
Code & Flowchart Identification:
1.???? Use flowcharts to visualize code execution and analyze functionalities.
2.???? Identify potential code segments and trace outputs for vulnerability understanding.
Design Test Cases:
1.???? Create detailed scenarios for each code segment and system functionality.
2.???? Include boundary testing and attack simulations in test cases.
Execute Testing:
1.???? Implement testing plans rigorously for thorough examination.
2.???? Document findings, validate vulnerabilities, and refine procedures.
Reporting:
1.???? Compile a detailed report listing vulnerabilities, impact, and mitigation recommendations.
2.???? Prioritize vulnerabilities based on severity for effective mitigation.
Continuous Improvement:
1.???? Maintain security through ongoing monitoring, assessments, and policy improvements.

Conclusion
If you're developing a software or application, one of the best methods to check vulnerabilities it is white box penetration testing. It is the same as black box penetration, but here the testers have all the knowledge about the internal coding structure. Businesses can apply this security testing approach to prevent mistakes that could expose their company to cyber threats.
