CISA Exam - Question 539


Which of the following is the MOST reliable way for an IS auditor to evaluate the operational effectiveness of an organization's data loss prevention (DLP) controls?

Show Answer
Correct Answer: BC

Verifying that confidential files cannot be transmitted to a personal USB device is the most reliable way to evaluate the operational effectiveness of an organization's data loss prevention (DLP) controls. This action directly tests one of the core functions of a DLP system—preventing unauthorized data transfers. Merely ensuring the software is installed (option C) does not confirm that it is functioning correctly in practice.

I think is B as it says operational effectiveness. C is more in design.

While verifying the installation of DLP software on all computer systems (option C) is important, it does not directly assess the functionality or effectiveness of the DLP controls in preventing data loss incidents. Testing specific functionalities, such as preventing data transfers to USB devices, provides more direct evidence of the operational effectiveness of the DLP controls.

Testing samples helps to determine operational effectiveness
