CISSP › Communication and Network Security
Domain 4 covers securing data in motion across OSI layers: secure protocols, network architecture, and transmission media. CISSP questions present attack scenarios (rogue APs, on-path interception, weak authentication) and ask you to select the correct protocol, control, or countermeasure. Expect to compare IPSec, TLS, SSH, DNSSEC, and VPN types by their cryptographic guarantees and failure modes.
