CP-10: INFORMATION SYSTEM RECOVERY AND RECONSTITUTION
TAILORED FOR INDUSTRIAL CONTROLS SYSTEMS
The organization provides for the recovery and reconstitution of the information system to a known state after a disruption, compromise, or failure.
SUPPLEMENTAL GUIDANCE
Recovery is executing information system contingency plan activities to restore organizational missions/business functions. Reconstitution takes place following recovery and includes activities for returning organizational information systems to fully operational states. Recovery and reconstitution operations reflect mission and business priorities, recovery point/time and reconstitution objectives, and established organizational metrics consistent with contingency plan requirements. Reconstitution includes the deactivation of any interim information system capabilities that may have been needed during recovery operations. Reconstitution also includes assessments of fully restored information system capabilities, reestablishment of continuous monitoring activities, potential information system reauthorizations, and activities to prepare the systems against future disruptions, compromises, or failures. Recovery/reconstitution capabilities employed by organizations can include both automated mechanisms and manual procedures.
ICS SUPPLEMENTAL GUIDANCE
Reconstitution of the ICS includes consideration whether system state variables should be restored to initial values or values before disruption (e.g., are valves restored to full open, full closed, or settings prior to disruption). Restoring system state variables may be disruptive to ongoing physical processes (e.g., valves initially closed may adversely affect system cooling).

CONTROL ENHANCEMENTS
CP-10 (1) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | CONTINGENCY PLAN TESTING
NOT SELECTED FOR THE NIST ISC CONTROL SET
[Withdrawn: Incorporated into CP-4].
CP-10 (2) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | TRANSACTION RECOVERY
ICS Control Baselines:
- Moderate
- High
The information system implements transaction recovery for systems that are transaction-based.
Supplemental Guidance:
Transaction-based information systems include, for example, database management systems and transaction processing systems. Mechanisms supporting transaction recovery include, for example, transaction rollback and transaction journaling.
No ICS Supplemental Guidance
CP-10 (3) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | COMPENSATING SECURITY CONTROLS
[Withdrawn: Addressed through tailoring procedures].
CP-10 (4) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | RESTORE WITHIN TIME PERIOD
ISC Control Baseline:
- High
The organization provides the capability to restore information system components within [Assignment: organization-defined restoration time-periods] from configuration-controlled and integrity-protected information representing a known, operational state for the components.
Supplemental Guidance:
Restoration of information system components includes, for example, reimaging which restores components to known, operational states.
No ICS Supplemental Guidance
RELATED CONTROLS: CP-10 (4)
CP-10 (5) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | FAILOVER CAPABILITY
NOT SELECTED FOR THE NIST ISC CONTROL SET
[Withdrawn: Incorporated into SI-13].
CP-10 (6) INFORMATION SYSTEM RECOVERY AND RECONSTITUTION | COMPONENT PROTECTION
NOT SELECTED FOR THE NIST ISC CONTROL SET
The organization protects backup and restoration hardware, firmware, and software.
Supplemental Guidance:
Protection of backup and restoration hardware, firmware, and software components includes both physical and technical safeguards. Backup and restoration software includes, for example, router tables, compilers, and other security-relevant system software.
