ISC2 Certified Cloud Security Professional (CCSP) Practice Question

The essential purpose of a data-flow diagram is to show how data moves between processes, storage locations, and external entities. The moments that require the greatest scrutiny are those in which data crosses a trust boundary-moving from one security domain or network zone to another-because control sets, identities, and attack surfaces change at that point. Highlighting these boundaries makes it clear where additional safeguards such as TLS, VPN tunneling, or tokenization must be applied. Details such as CPU reservations, runtime versions, or backup scheduling are important for capacity planning and operations, but they do not directly reveal where data could be exposed in transit and therefore are far less useful when the goal is to identify compliance-relevant exposure points in the flow.
