ICS/OT Product Security
Our Product Security service helps OEM manufacturers build security into industrial products from the design phase. We assess development processes, review product architectures, and prepare organizations for IEC 62443 product certification, covering both the development lifecycle (4-1) and the technical security requirements (4-2).
Securing the Product, Not Just the Network
OT cybersecurity is not only about protecting networks and facilities. The products deployed in those environments, PLCs, controllers, drives, sensors, and edge devices, must themselves be built with security in mind. Customers and regulators increasingly require evidence that industrial products meet security standards like IEC 62443-4-1 and 4-2.
Our Product Security service works with OEM manufacturers to evaluate and improve the security of their development processes and product architectures. We assess current practices, identify gaps against IEC 62443 requirements, and prepare organizations for formal product certification.
What We Cover
- Secure Development Lifecycle (SDL) assessment
- IEC 62443-4-1 process alignment
- IEC 62443-4-2 product requirements mapping
- Product security architecture review
- Secure coding and design practice evaluation
- Compliance and certification readiness
- Documentation for certification submission
Product Lifecycle Security
Building security into industrial products from requirements through certification
Engagement Methodology
A structured, phased approach designed for the safety, availability, and compliance requirements of operational technology environments.
Secure Development Lifecycle Assessment
Evaluate the current product development process against IEC 62443-4-1 requirements. Identify gaps in security practices across the full lifecycle including requirements, design, implementation, verification, validation, defect management, and end-of-life.
Product Security Architecture Review
Review the product security architecture including authentication mechanisms, access controls, communication protocols, update mechanisms, key management, and data protection. Identify design-level vulnerabilities and recommend architectural improvements aligned with the target security level.
IEC 62443-4-1 and 4-2 Alignment
Map the product development process and product capabilities against IEC 62443-4-1 (secure development lifecycle) and IEC 62443-4-2 (technical security requirements for IACS components). Produce a detailed gap analysis with specific remediation guidance for each requirement.
Secure Coding and Design Practices
Review source code and design patterns for security weaknesses. Establish secure coding guidelines, input validation practices, cryptographic standards, error handling procedures, and threat modeling practices specific to industrial product development.
Compliance and Certification Readiness
Prepare documentation and evidence packages required for IEC 62443 product certification. Conduct pre-certification assessments, identify remaining gaps, and develop a remediation plan to achieve certification readiness within a defined timeline.
