Field-Level Encryption for Sensitive Data

Encrypt sensitive data at the edge before it leaves your network boundary.

The Problem

TLS protects data in transit but leaves it vulnerable at rest:

• Credit card numbers exposed to cloud operators
• SSNs visible in logs and backups
• Email addresses accessible to compromised services
• PII compliance violations

The Solution

Learn 6 field encryption techniques:

1. Credit Card Encryption - AES-256-GCM with partial preservation for PCI-DSS compliance
2. PII Data Encryption - Multi-field encryption for SSN, email, phone with selective preservation
3. Address Data Encryption - Street-level encryption while preserving geographic trends
4. Key Management - Secure key storage, rotation, and versioning for production operations
5. Selective Decryption - Key segregation and service authorization for granular access
6. Compliance Monitoring - Encryption metadata and audit logging for regulatory requirements
