Why OT Security Matters
With the rise of cyberattacks targeting factory production systems, securing Operational Technology (OT) has become more critical than ever. Cyber incidents can lead to severe disruptions, including large-scale production halts and significant reputational damage. To prevent such outcomes, organizations must comply with both industry-specific and global security standards.
As smart factories and the Industrial Internet of Things (IIoT) continue to advance, the exposure to OT-related security risks grows. Building a robust security infrastructure that encompasses OT environments is essential for ensuring safe, reliable, and future-ready manufacturing operations.
Our OT Security Consulting Services
With decades of hands-on experience in manufacturing and technology development, Yokogawa has built deep expertise in Operational Technology (OT), refined within our own production facilities. By combining this OT proficiency with strong IT capabilities, we deliver tailored security solutions that meet the unique needs of your operations.
As OT security becomes an increasingly urgent priority across the industry, many manufacturers are searching for practical, actionable strategies. Yokogawa offers a comprehensive suite of consulting services backed by proven experience. We’re here to help you navigate complex security challenges and implement effective, forward-looking protections for your OT environment.
Our OT Security Service Flow
At Yokogawa, we begin by thoroughly assessing your current operational environment to identify potential security risks and vulnerabilities. Based on this understanding, we propose targeted, practical security measures aligned with your specific needs.
Our support spans the entire security lifecycle—from requirements definition and system design to implementation and ongoing operation. Services are modular and flexible, allowing you to select only the components that match your priorities and budget.
Service Menu Details
1. Security Risk Assessment
We will conduct an "as-is" security assessment according to the customer's manufacturing site. we conduct a security risk analysis at the customer's production site based on various security standards, criteria, and guidelines as follows.
- Ministry of Economy, Trade and Industry, The Cyber/Physical Security Guidelines for Factory Systems
- IPA Security Risk Assessment Guide for Industrial Control Systems
- NIST Cybersecurity Framework (CSF)
After the assessment, we will propose a 'Ideal state of security' tailored to the customer along with the report.
Deliverables:
- OT Security Assessment Report
- Proposal of OT security measures.
Duration: 3months~
Example of assessment results
2. Formulation of guidelines and policies
In implementing security measures at manufacturing sites, it is important to formulate "OT Security policies" that serve as guidelines. At Yokogawa, we will formulate policies tailored to each manufacturing site. Specifically, it includes the following perspectives.
- Network design on the shop floor
- OT Security Measures for Manufacturing Devices
- Development of security infrastructure for the realization of smart factories
As a guideline for security measures, we support the formulation of "feasible" policies while interviewing the site.
In addition to the policies, we also support the creation of documents used on-site, such as operation manuals.
We will facilitate the development of practical OT security guidelines and policies between the headquarters IT department and the factory OT department.
3. Support for building an incident response system
Security never ends. The incident risk can be reduced as much as possible, but it is difficult to reduce the risk to zero.
It is necessary to establish a response system in order to detect security incidents at an early stage and to respond and recover quickly.
Based on our experience in building an incident response system (F-SIRT) using our own SOC, Yokogawa will propose the optimal response flow for our customers and support the construction of the system.
Deliverable
- Security Incident Response Flow
- Security Incident Response Manual
- Security Risk Management Regulations
Duration: 6months~
