Prove OT Backup Integrity and Safe Restoration
Construction terms explained
OT:
operational technology
IST:
integrated systems testing
Use before
Early-life review · Integrated systems testing · Operations acceptance and ready for service
Action
Inventory backed-up operational logic, programs, configurations, images, firewall and ACL data, then prove safe restoration on an approved sample or use a documented compensating integrity method where live restoration is unsafe.
Responsible role
Controls integration lead
Warning signs
Backup success is reported without a restoration or integrity test. · A recovery image includes live physical-state values without an approved safe-state rule.
