Which of the following describes fuzzing most accurately?

• A. The process of cleaning up code
• B. Testing for system failures and bugs
• C. Securing software from external threats
• D. Optimizing software performance

Answer: (B)

Fuzzing is a software testing technique specifically designed to identify vulnerabilities, bugs, and system failures by inputting random, unexpected, or malformed data into a program. The primary goal is to uncover how the system behaves under unconventional or erroneous input. By doing so, developers can observe the program's response to these inputs, which can reveal weaknesses in error handling, memory management, and other critical areas that might be exploited by attackers. This method is especially important in security testing, as it helps ensure that applications can handle invalid or malicious inputs gracefully without crashing, leaking sensitive information, or permitting unauthorized access. While the other options involve different aspects of software development and security, they do not capture the specific focus of fuzzing on detecting faults through abnormal input handling.
