SC-31(2): Covert Channel Analysis | Maximum Bandwidth

Control Text:

Reduce the maximum bandwidth for identified covert [Selection (one or more): storage; timing] channels to [Assignment: organization-defined values].

The complete elimination of covert channels, especially covert timing channels, is usually not possible without significant performance impacts.
