What is the primary use of TLS or IPsec in mission computer networks?

• A. To provide data compression.
• B. To protect data in transit and provide authentication.
• C. To replace all encryption at rest.
• D. To manage keys.

Answer: (B)

Securing data in transit and authenticating the communicating parties. In mission computer networks, sensitive information travels across links that could be observed or tampered with. TLS and IPsec provide encryption of the payload so an eavesdropper can’t interpret it, and they verify identities so you know who you’re talking to. They also protect integrity so any changes in transit are detectable. This combination is what makes TLS and IPsec essential for protecting data in motion and ensuring trusted connections. They are not primarily about data compression, and encryption at rest is a separate concern. While they include mechanisms for establishing cryptographic keys, their main purpose is protecting in-flight data and authenticating endpoints.
