id: "SC-31(02)" title: "Maximum Bandwidth" family: "SC" family_name: "System and Communications Protection" sort_id: "sc-31.02" priority: "P1" implementation_level: "organization" parent: "SC-31" enhancement: True
Statement
Reduce the maximum bandwidth for identified covert {{ insert: param, sc-31.02_odp.01 }} channels to {{ insert: param, sc-31.02_odp.02 }}.
Guidance
The complete elimination of covert channels, especially covert timing channels, is usually not possible without significant performance impacts.
Assessment Objective
the maximum bandwidth for identified covert {{ insert: param, sc-31.02_odp.01 }} channels is reduced to {{ insert: param, sc-31.02_odp.02 }}.
