Question

While troubleshooting a broken encrypted session between a city workstation and a cloud case portal, an engineer needs to reason about which networking layer typically provides confidentiality services for that session. Which approach best applies OSI/TCP-IP models?

Accepted Answer

Use OSI/TCP-IP layering to locate where session encryption (for example TLS at the application/transport boundary) provides confidentiality versus lower-layer framing. — Layer models are the map when an encrypted session breaks—you find whether the problem is crypto at the session/app edge or something lower. Guessing at cables or rebooting at random wastes the afternoon.

Answer

Assume confidentiality always exists only at the physical cable jacket layer.

Answer

Ignore layered models and restart random switches until the session returns.

Answer

Conclude that the network layer never participates in any security discussion.
