What is NIST 800-111 about?

• A. Storage Encryption
• B. Key Management
• C. Telework/Remote Access
• D. PIV

Answer: (A)

This item tests your knowledge of what NIST 800-111 covers. NIST Special Publication 800-111 is the Guide to Storage Encryption Technologies and Methods, and its focus is protecting data at rest by encrypting stored information. It explains the different storage encryption approaches—such as full-disk, file-level, and hardware-based encryption—and guides how to choose appropriate algorithms, modes, and implementations for various storage environments. It also addresses key management considerations within storage encryption, as well as the trade-offs in performance and integration with systems. The other options relate to topics outside the scope of this publication: remote access security, identity credentials, or general key management policies not specifically about protecting data at rest on storage devices. That makes storage encryption the best fit.
