What was published
On June 17, 2026, the NIST National Cybersecurity Center of Excellence (NCCoE) updated NIST Special Publication (SP) 1339, titled “Operational Technology Backup Quick Start Guide.” This document serves as a concise resource for operators and manufacturers to establish cybersecurity considerations within their OT backup strategies.
Status and scope
The publication is a two-page “Quick Start Guide” rather than an exhaustive technical manual. Its primary scope is the manufacturing sector, though its principles apply broadly to OT environments where system availability is critical. The guidance focuses on high-level management priorities for backups to facilitate recovery from system failures or cyberattacks.
What the guidance covers
The guide emphasizes that backup failures in industrial settings can lead to severe operational consequences, specifically citing safety incidents, financial losses, and extended production downtime. To address these risks, the publication identifies four key management priorities:
* Change Management Integration: Ensuring backups are synchronized with changes made to the OT environment.
* Regularity: Establishing a consistent schedule for creating backups.
* Verification: Implementing testing procedures to ensure backups are functional.
* Recovery Exercises: Reviewing backup efficacy during simulated recovery events.
How organizations can use it
Asset owners and plant managers can utilize this guide as a baseline to evaluate the maturity of their current recovery capabilities. Rather than providing specific software configurations, the document provides a framework for OT security leaders to align their backup processes with broader operational resilience goals. It is intended to be used as an entry point for organizations to identify gaps in their current backup lifecycle—from creation to validation.
Decisions and next steps
Based on this guidance, our analysis suggests that OT operators should prioritize the following decision checkpoints:
1. Audit Change Control: Determine if a backup is triggered automatically or manually whenever a PLC program or HMI configuration is modified. If not, this represents a gap in synchronization.
2. Validate Recovery Time Objectives (RTO): Use recovery exercises to measure the actual time required to restore a system from backup versus the business-required downtime limit.
3. Verify Backup Integrity: Move beyond confirming that a backup file exists; implement a process to verify that the data within the backup is bootable or deployable to spare hardware.
Limits and open questions
As a “Quick Start Guide,” SP 1339 does not provide step-by-step technical instructions, specific product recommendations, or brand-specific configuration commands for PLCs or historians. It does not offer a guarantee that following these priorities will prevent all recovery failures. Organizations must still determine the appropriate frequency of backups and the specific storage media (e.g., offline vs. online) based on their unique risk profile and hardware constraints.
