CISSP Practice Question – Domain 4 (Communication & Network Security)
A global enterprise adopts a strict zero-trust network architecture. All workloads—on-prem, cloud, and containerized—must mutually authenticate before communicating. To comply with regulatory requirements, the company must also maintain full packet-level visibility for threat analysis and incident response. Which solution BEST satisfies all of these requirements simultaneously? A. Deploy full end-to-end TLS between all workloads and rely on IDS/IPS to inspect only metadata and flow logs. B. Use a TLS termination proxy at network choke points and decrypt all internal traffic for inspection before re-encrypting. C. Implement mutual TLS within a service mesh that supports encrypted telemetry export and out-of-band traffic mirroring for deep packet inspection. D. Use host-based agents to perform inline decryption on each workload and send decrypted payload streams to the central IDS via secure channels.
