Data Loss Prevention (DLP) Survival Guide w/ Ashley Knowles

This webcast introduces a survival guide for Data Loss Prevention (DLP) systems, outlining how attackers can evade detection and providing defensive recommendations for security teams 0:00.

Key Takeaways:
• The presentation addresses the gap in pentest reporting regarding DLP evasion, noting that clients often struggle to understand how data exfiltration occurs despite existing protections 0:21.
• Attackers can bypass DLP by using standard protocols like HTTPS, DNS, or cloud storage APIs, which often appear as legitimate traffic to security appliances 0:30.
• Evasion techniques include encrypting data before exfiltration, using steganography to hide data within images or files, and fragmenting large data sets to avoid threshold-based alerts 1:15.
• Defenders should implement network segmentation, monitor for anomalous outbound traffic patterns, and utilize endpoint detection and response (EDR) tools to complement network-level DLP 2:00.

Effective DLP requires a layered defense strategy that combines network monitoring with endpoint visibility to detect sophisticated exfiltration attempts. Security teams must regularly test their DLP configurations against real-world evasion techniques to ensure robust protection.
