Question: What is the purpose of validation strategies in security assessment and testing?

A.     To ensure compliance with regulatory requirements

B.     To define the scope of testing activities

C.     To evaluate the accuracy of test results

D.    To assess the effectiveness of security controls

Correct Answer:  C

Explanation: 

Ensure compliance with regulatory requirements: While security assessment and testing can be a part of compliance efforts, validation strategies specifically aim to ensure the accuracy of the test results, not compliance per se.

Define the scope of testing activities: The scope is generally defined before the testing activities commence. Validation strategies come into play after testing has been performed, to confirm that the results are accurate.

Evaluate the accuracy of test results: This is the primary purpose of validation strategies. They help to confirm that the vulnerabilities and weaknesses identified during testing are real and actionable, thereby ensuring the reliability of the test outcomes.

Assess the effectiveness of security controls: While testing may indeed evaluate the effectiveness of security controls, validation strategies are more concerned with verifying the accuracy of these test results, not the effectiveness of the controls themselves.
