Explanation

After an insider threat successfully exfiltrated customer PII, the core vulnerability is the lack of controls preventing unauthorized data movement. Data Leak Prevention (DLP) tools directly remediate this vulnerability by monitoring, detecting, and blocking unauthorized transfers of sensitive data based on content, destination, and user policies. Implementing DLP addresses the root cause of what the insider exploited-the absence of data exfiltration controls. A protocol analyzer (A) captures network traffic for analysis but does not remediate. Root cause analysis (B) is an investigative methodology, not a remediation tool. Behavioral analytics (C) can detect anomalies but does not prevent or remediate data exfiltration vulnerabilities.
