A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
Which security property protects a message from modification while it crosses the network?
Correct.
Concept
The CIA triad separates three assurances: keeping data secret, keeping data unaltered, and keeping systems reachable. Each maps to different controls and different attacks.
Why C
Protection against modification in transit is the integrity guarantee; TLS provides it alongside confidentiality, so tampering or replaying traffic is detectable.
