Which is NOT an important tool for transmission security?

• A. Solid-state drive
• B. Firewall
• C. Encryption
• D. Virtual Private Network (VPN)

Answer: (A)

Transmission security aims to protect data while it’s moving across networks, focusing on keeping information confidential, intact, and authentic from sender to receiver. Firewalls help by controlling which traffic can enter or leave a network, reducing exposure to threats. Encryption is central because it makes intercepted data unreadable, preserving confidentiality in transit. A VPN takes that protection further by creating an encrypted tunnel for all traffic between endpoints, shielding data from eavesdroppers and tampering as it travels. A solid-state drive, on the other hand, is primarily a storage device. Its encryption, if present, tends to protect data at rest, not data in motion. So it doesn’t directly contribute to securing information during transmission. That’s why it’s not considered an important tool for transmission security.
