MANUFACTURING CYBERSECURITY

Keep production moving. Protect what makes it possible.

Connect production continuity, controlled access and recovery planning around the way your facility operates.

PRODUCTION IS THE PRIORITY

Protect the work behind every shift.

Availability, safety and quality give security decisions their context.

A production line depends on more than the equipment in front of it. Scheduling, engineering files, identity services, supplier support and business systems may all be part of the route from an order to a finished product.

Ransom Secure helps frame a review around those dependencies. Bring operations, IT and equipment owners into the same discussion so that access changes and recovery priorities reflect the way the site actually runs. A specialist production environment needs an explicitly agreed scope.

TRACE ONE PRODUCT JOURNEY

Follow the line. Find the dependencies.

Illustrative service map: the actual systems and permitted connections are established with your team.

Plan the work

Orders, scheduling and engineering instructions define what the line should produce. Identify which information must be available and current at the start of a shift.

Run the process

Controllers, operator workstations and production networks support the physical process. Record ownership, support constraints and the consequence of a change.

Check the result

Quality records and measurement systems help determine whether output is acceptable. A restored machine is not enough if its configuration or supporting records are unreliable.

Release and deliver

Inventory, labelling and logistics close the loop. Include the applications and supplier connections required to release finished work.

CONTROL THE CONNECTION

Remote support should have a defined job.

Equipment suppliers may need access to investigate a fault or perform maintenance. That need does not establish a reason for permanent, unrestricted access to the wider environment.

Review the route, the identity, the approved purpose and the conditions for ending a session. Confirm arrangements with the supplier and the people responsible for production before making changes.

Review our production dependencies

ILLUSTRATIVE ACCESS PERMIT

Purpose

A named maintenance task and the specific equipment involved.

Authority

A person who approves the session and understands its operational impact.

Boundary

The accounts, systems and connections the task actually requires.

Evidence

A record of access, work performed and the point at which access ends.

A FOCUSED REVIEW

Work across the factory boundary.

Separate access paths

Examine how business IT, production systems and vendor routes connect. Document necessary flows before deciding where segmentation or additional verification is appropriate.

Know the support constraints

Record equipment support arrangements, software dependencies and update restrictions. A security recommendation must account for approved maintenance windows and vendor requirements.

Protect engineering information

Review access to designs, recipes, controller configurations and project files. Identify authoritative copies and the people who can approve a production change.

Prepare useful recovery copies

Include configurations, licences, documentation and access requirements in recovery planning. Establish what can be tested safely and who validates the restored process.

OPERATIONS + IT + EQUIPMENT OWNERS

Put the right people behind the decision.

A network diagram cannot explain every constraint on a production floor. The people running and maintaining the equipment can identify dependencies, safe working conditions and the consequences of an interruption that may not appear in an inventory.

Use that knowledge to shape the review. Agree who approves a change, who supplies the technical evidence and who confirms that the process is ready to return to service. Record the decisions so that a future shift or supplier can follow them.

CHANGE WITH CONTROL

Use the maintenance window deliberately.

Before the window

Agree the change, responsible people, expected impact, test conditions and rollback route. Confirm that needed files and support contacts are available.

During the work

Follow the authorized scope and record deviations. Keep operations involved in decisions that affect production rather than treating them as a final notification.

Before handover

Validate the relevant process and supporting information. Record unresolved issues, restore unnecessary temporary access to its intended state and assign follow-up actions.

LEAVE WITH PRACTICAL OUTPUTS

Turn the review into an operating plan.

A dependency record

The agreed line, systems, providers and constraints examined, including important gaps in the available evidence.

An access improvement plan

Prioritized actions for supplier routes, privileged accounts and necessary network connections, with named owners.

A recovery test scope

The configurations, people and acceptance checks needed for a controlled rehearsal. Deliverables depend on the agreed engagement.

QUESTIONS, ANSWERED

Plan the next step with clarity.

Does this cover both business IT and production systems?

The scope can consider their dependencies and access boundaries. Specialist operational technology activities, equipment testing and production changes need appropriate expertise, explicit authorization and coordination with equipment owners.

Will you scan or change equipment without our operations team?

No production activity should be assumed from a general enquiry. Review methods, access and any testing or changes must be agreed with the responsible team before work begins.

Can older equipment still be included in the plan?

Yes. Record its support status, operating constraints and dependencies. Where an immediate change is not appropriate, discuss access restrictions, monitoring options and longer-term replacement decisions with the equipment owner.

Why review supplier remote access?

A support route may connect external identities to important systems. Reviewing its purpose, permissions, approval and expiry helps establish whether access matches the maintenance need.

Is segmentation simply installing another firewall?

No. Useful boundaries start with understanding necessary connections and operational constraints. Products support the design, but ownership, rules, testing and maintenance determine whether it remains useful.

What should a production recovery test include?

Agree the scope with operations. It may include configuration availability, required software and licences, supporting systems and the checks used to accept the restored process. Testing must not create an uncontrolled production risk.

Can you work with our machine suppliers and existing IT provider?

Yes, within a jointly agreed scope. Identify who owns equipment decisions, network changes and validation so that findings can be implemented by the right people.

What should we bring to the first discussion?

Describe one important production process, its business-system dependencies, key suppliers and the main concern. A high-level diagram is useful; do not submit confidential engineering files or credentials through the enquiry form.
