Which of the following tools can assist with detecting an employee who has accidentally emailed a file containing a customer’s PII?

Data Loss Prevention (DLP) systems are designed to prevent sensitive information, such as Personally Identifiable Information (PII), from leaving an organization's control. They monitor, detect, and block unauthorized data transfers, including accidental emails containing PII. DLP solutions can be configured with policies to identify and intercept specific types of data based on content, context, and destination. SCAP (Security Content Automation Protocol) is a suite of specifications for maintaining the security of enterprise systems, not for detecting data exfiltration. NetFlow is a network protocol used for collecting IP traffic information, primarily for network monitoring and troubleshooting, not for content inspection of emails. Antivirus software primarily detects and removes malicious software, not sensitive data in legitimate communications.
