Protecting data at rest and in transit.

🎯 Learning Objectives

  • ▸ Understand what constitutes "reasonable security"
  • ▸ Learn the difference between encryption at rest and in transit
  • ▸ Identify industry standards for encryption

Encryption Basics

Encryption is the process of converting personal data into an unreadable format (ciphertext) so that even if a hacker steals the database, they cannot read the information without the decryption key.

Data at Rest vs Data in Transit

  • • Encryption at Rest: Protecting data stored on servers, hard drives, or cloud databases (e.g., AWS RDS encryption, BitLocker).
  • • Encryption in Transit: Protecting data as it moves over the network (e.g., HTTPS, TLS, VPNs).

If a company stores plain text credit card numbers, passwords, or health records, it is a direct violation of the obligation to implement reasonable security safeguards.

📖 Glossary

Encryption
The process of encoding information so that only authorized parties can access it.
AES-256
An advanced encryption standard widely used by governments and businesses to protect classified information.

🔑 Key Takeaways

  • Encryption scrambles data so it cannot be read without a key.
  • Use AES-256 for data at rest and TLS 1.2+ for data in transit.
  • Encryption is required but not sufficient on its own.
