id: "SC-31(03)" title: "Measure Bandwidth in Operational Environments" family: "SC" family_name: "System and Communications Protection" sort_id: "sc-31.03" priority: "P1" implementation_level: "organization" parent: "SC-31" enhancement: True
Statement
Measure the bandwidth of {{ insert: param, sc-31.03_odp }} in the operational environment of the system.
Guidance
Measuring covert channel bandwidth in specified operational environments helps organizations determine how much information can be covertly leaked before such leakage adversely affects mission or business functions. Covert channel bandwidth may be significantly different when measured in settings that are independent of the specific environments of operation, including laboratories or system development environments.
Assessment Objective
the bandwidth of {{ insert: param, sc-31.03_odp }} is measured in the operational environment of the system.
