Why Companies Need White Box Penetration Testing

White box — also known as clear box — pen tests evaluate your company’s software structure, validate input-output flow, and ensure that internal operations comply with specifications. It is a security assessment method where the ethical hacker has complete knowledge of the system being examined, including its source code and architecture. This approach seeks to identify vulnerabilities from an insider’s perspective and has these objectives:

  • Assess each specific function, object, and statement
  • Prevent internal security breaches
  • Evade poorly structured code paths
  • Manage certain inputs and anticipated outputs
  • Ensure the correct functioning of conditional loops

A successful white box penetration test will help your company circumvent the errors and oversights that could leave your business vulnerable to hackers. Moreover, they equip staff with the knowledge to manage any intrusion from a malicious entity.

Aside from that, it helps firms, as it guarantees robust and secure software. The efficiency of this approach results in a streamlined and quick process, saving time and reducing costs. Also, the comprehensive nature of the checks, involving meticulous code analysis and access to an array of information, guarantees a thorough system examination. This ensures that no stone is left unturned in identifying potential vulnerabilities.

Moreover, by integrating white box pen tests early in the Software Development Life Cycle (SDLC), companies can detect and rectify online safety flaws before the product reaches the customer. This proactive approach enhances the reliability and security of the software, fortifying the business's reputation and customer trust.

Types of White Box Pen Testing

Unit testing: Experts apply the white box technique to evaluate the code's performance. The employment of this method facilitates early identification of most bugs within the SDLC at a stage when they are simpler and more cost-effective to rectify.

Integration testing: A unit may operate flawlessly, but when integrated with others, complications can occur. This check is conducted to confirm proper connection and interaction with different systems and is done by examining the source code components as a collective entity. It prevents errors arising from disparate code and logic, enhances coverage, and offers an additional layer of reliability.

Regression testing: Changes in the code can trigger defects and malfunctions to appear or reappear. Regression tests are executed to mitigate these risks and ensure it continues functioning well. This step is critical in assuring the software's overall stability.

Acceptance testing: Upon completion of system checks, the examiners evaluate the software's performance in a real-world environment. This phase aims to confirm that all process flows have been adequately addressed.

Techniques Used in White Box Tests

  1. Statement coverage: A statement in software development is a line of code that directs the compiler to perform a certain action that should be executed at least once. This is what the statement coverage technique is designed for. Developers rectify erroneous statements if a section is unused or unreachable due to programming errors or updates.
  2. Branch coverage: A branch is an instruction that orders a computer to execute different commands instead of running the statements sequentially. This may include if-else and other conditional loops with true and false branches. Therefore, the expert establishes two conditions using this method: one for true and the other for false. The primary purpose of this technique is to ensure each branch is covered and executed at least once.
  3. Path coverage: Using the path coverage method, the examiner scrutinises the entire programme along all possible paths, from beginning to end. This comprehensive technique ensures all paths are functional, efficient, and necessary.

White Box Pen Testing Steps

  1. Planning and Preparation
    This beginning phase of the penetration testing process centres on collecting data about the target system. Typically, this is undertaken through meetings with developers where the application, attributes, and functions are detailed. Login details and source code are supplied, and the application's logic flow is explained.
  2. Scanning and Discovery
    During this stage, the expert seeks more information by looking for security flaws using tools like Nmap. The scan usually yields details such as the operating system version and the software type. Also, it checks for vulnerable versions of the operating software.
  3. Vulnerability Analysis
    The penetration tester should now search for publicly known susceptibilities and attack entry vectors that could serve as potential routes into the target. This might encompass but is not restricted to, known Common Vulnerabilities and Exposures (CVEs) in the system, susceptible versions, and third-party applications utilised by the target.
  4. Proof Of Concepts
    At this juncture, the professional will have noted several potential susceptibilities attackers can exploit gathered via automated scanning and manual research. For each weakness detected, the examiner creates proof of concepts to demonstrate that they are exploitable and pose a security risk.
