# SC-32 System Partitioning

NIST SP 800-53 control. Family: SC System and Communications Protection. Function: preventative. In no baseline. Mapping licence: CC BY-SA 4.0.

Statement: Partition the system into [Assignment: organization-defined system components] residing in separate [Selection (one): physical; logical] domains or environments based on [Assignment: organization-defined circumstances for physical or logical separation of components].
Guidance: System partitioning is part of a defense-in-depth protection strategy. Organizations determine the degree of physical separation of system components. Physical separation options include physically distinct components in separate racks in the same room, critical components in separate rooms, and geographical separation of critical components. Security categorization can guide the selection of candidates for domain partitioning. Managed interfaces restrict or prohibit network access and information flow among partitioned system components.

OSA's mapping for iso_27001_2022 and nist_csf_2 takes NIST's published crosswalk as its base. A clause not marked as OSA's own is in that crosswalk.
