What technique will work best with a data loss prevention tool to identify data exfiltration?

A honeyfile is an effective technique to use alongside a data loss prevention tool for identifying data exfiltration because it acts as a decoy or trap for unauthorized access. Honeyfiles are essentially files that appear valuable or sensitive but are actually fake or contain no real data. When a hacker or unauthorized user accesses or attempts to exfiltrate the honeyfile, this action can be easily monitored and logged by the data loss prevention tool.

This proactive measure helps organizations detect potential breaches or malicious activity, as interactions with the honeyfile can be flagged as suspicious, providing early warning signs of data exfiltration attempts. The movement of these files can be tracked, and alerts can be generated, facilitating a rapid response to potential threats.

Other techniques mentioned, such as access controls, encryption, and network monitoring, also contribute to security, but they serve different purposes. Access controls are directly related to managing user permissions, encryption protects data at rest or in transit, and network monitoring focuses on observing traffic patterns. While these are all important elements of a comprehensive security strategy, honeyfiles stand out for their effectiveness in detecting specific data exfiltration attempts through intentional traps designed to catch unauthorized actions.
