SC-4(2) Multilevel or Periods Processing
Control enhancement of SC-4 Information in Shared System Resources
Control
Prevent unauthorized information transfer via shared resources in accordance with [Assignment: procedures] when system processing explicitly switches between different information classification levels or security categories.
Discussion
Changes in processing levels can occur during multilevel or periods processing with information at different classification levels or security categories. It can also occur during serial reuse of hardware components at different classification levels. Organization-defined procedures can include approved sanitization processes for electronically stored information.
Need SC-4(2) implemented and evidenced?
We assess where you stand against this control, document the gap, and build the remediation plan your auditor and your board will both accept.
