Manufacturers depend on systems that support production, inventory, scheduling and shipping. Cybersecurity decisions must account for how those systems interact and what happens when one becomes unavailable.
A useful starting point is to examine assumptions about equipment isolation, remote access and recovery.
Myth 1: Production Equipment Is Safe Because It Is Not Publicly Accessible
A system can have indirect connections through engineering workstations, maintenance laptops, removable media or vendor access. Limited internet exposure does not establish complete isolation.
What to do: Document connections between business and production systems. Review how people, devices and external providers reach equipment.
Myth 2: Business Devices and Production Systems Can Use the Same Security Approach
Production environments may include equipment with specific availability, compatibility and vendor requirements. Changes that work on office computers may disrupt an industrial system.
What to do: Coordinate security changes with operations, engineering and equipment vendors. Test changes and use approved maintenance windows.
Myth 3: Vendor Remote Access Can Stay Open Indefinitely
A connection established for maintenance can remain available long after the task is complete. Unnecessary access creates another route into the environment.
What to do: Approve remote access for a defined purpose and duration. Use individual accounts, strong authentication where supported and appropriate activity logging.
Myth 4: A Backup Means Production Can Restart Immediately
Restoring business files may not restore machine configurations, control programs or the supporting services needed for production.
What to do: Identify what recovery requires for each critical process. Protect relevant configurations and programs, and validate recovery procedures with qualified personnel.
Plan Security Around Production Requirements
Start with the processes your business needs to keep operating. Identify their dependencies, access paths and recovery requirements, then prioritize improvements with the people responsible for production.
