What term refers to securing email content to protect it from unauthorized access?

• A. HTTPS
• B. VPN
• C. Data in transit
• D. Email encryption

Answer: (D)

Email encryption protects the content of messages so only the intended recipient can read them by turning readable text into ciphertext. This is typically done with public-key cryptography (such as S/MIME or PGP), where the email is encrypted with the recipient’s public key and decrypted with their private key. It helps ensure confidentiality whether the message is in transit or stored, depending on the setup. HTTPS secures web traffic, a VPN creates a secure network tunnel, and data in transit is a broad term for data being transmitted—none of these specifically describe securing the content of an email. So the term that best refers to securing email content is email encryption.
