UC-NET-05 — Prevent leakage via shared resources and covert channels
Prevent unauthorized or unintended information transfer through shared system resources by clearing, sanitizing, or isolating resources between users and processes. Analyze the system for covert storage and timing channels, estimate their bandwidth, and reduce or eliminate identified channels that exceed acceptable thresholds.
