Free CompTIA CySA+ CS0-003 Practice Question

The correct answer is 'Testing for Input Validation' because the OWASP Testing Guide emphasizes the importance of validating user inputs to prevent various types of attacks such as SQL injection, XSS, and other injection flaws. Each input field should be tested to ensure it properly handles and sanitizes user input. Other answers are not correct because they focus on different aspects of security testing, like identifying outdated components or performing configuration audits which do not primarily address input validation issues.
