Master Key Management
Learn key lifecycle management, envelope encryption, key rotation, HSMs, and key management systems. Understand how poor key management undermines encryption.
Understand Data Classification and Handling
Study data classification frameworks (public, internal, confidential, restricted) and the security controls required at each level. Practice classifying real-world data types.
Study Privacy Regulations (GDPR, CCPA)
Learn the principles, requirements, and individual rights under major privacy regulations. Understand breach notification requirements, consent mechanisms, and compliance obligations.
Implement Secure Data Storage
Study encryption at rest, database security, access controls for stored data, secure backup strategies, and data retention policies.
Explore Data Lifecycle Management
Learn to manage data from creation through storage, use, sharing, archival, and secure destruction. Understand secure deletion methods and compliance requirements.
Learn Privacy-Enhancing Technologies
Study differential privacy, homomorphic encryption, data anonymization, pseudonymization, and federated learning. Understand how they enable analysis while preserving privacy.
Deploy Data Loss Prevention
Learn to implement DLP systems that monitor data in motion, at rest, and in use. Practice creating policies to detect and prevent unauthorized data exfiltration.
