Building a defense in depth strategy for sensitive data

Venkata Pavan Kumar Gummadi from Broadridge describes a defense in depth approach for protecting sensitive data across its lifecycle using multiple coordinated layers. He argues that single controls like disk encryption or data loss prevention (DLP) alone create gaps, and advocates for layered defenses that include data classification to identify sensitive fields such as Social Security numbers.

Why it matters: Security practitioners responsible for data protection need to understand that multi-layered controls reduce the seams attackers exploit; relying on one mechanism leaves exposure.
