CompTIA Security+ (SY0-601) — Question 685

A company recently experienced a significant data loss when proprietary information was leaked to a competitor. The company took special precautions by using proper labels; however, email filter logs do not have any record of the incident. An investigation confirmed the corporate network was not breached, but documents were downloaded from an employee's COPE tablet and passed to the competitor via cloud storage. Which of the following is the BEST remediation for this data leak?

Answer options

• A. User training
• B. CASB
• C. MDM
• D. DLP

Correct answer: D

Explanation

The best option for addressing the data leak is DLP (Data Loss Prevention), as it specifically focuses on preventing sensitive information from being shared or accessed improperly. User training (A) can help raise awareness but does not directly prevent data leaks. CASB (B) and MDM (C) can enhance security, but they do not provide the targeted protections that DLP offers against the unauthorized transfer of data.
