Component Security
for Industrial Devices
We help device manufacturers implement cybersecurity into their products — from structured threat modeling using STRIDE to hands-on implementation of security controls, aligned with IEC 62443-4-1 and IEC 62443-4-2.
IEC 62443-4 at a Glance
IEC 62443-4 defines security requirements at the component level — for the devices themselves, and for the processes used to develop them. Part 4-1 covers the secure development lifecycle; Part 4-2 defines the technical security requirements that a component must meet to achieve a given Security Level (SL 1–4).
Security requirements in 4-2 are organized across seven Foundational Requirements (FRs). We assess your device against all seven and prioritize findings by risk.
Our IEC 62443-4 Services
From threat modeling to verified implementation — we work directly with your development team to build security into your device.
IEC 62443-4-1: Secure Development Lifecycle
Establish a product security development process aligned with IEC 62443-4-1. We review and improve your existing SDL — covering security requirements, threat modeling, secure design, implementation guidelines, verification, and vulnerability management.
- SDL gap assessment against 4-1 practices
- Process improvement recommendations
- Security documentation templates
IEC 62443-4-2: Component Security Requirements
Evaluate and specify security requirements at the component level. We assess your device against the IEC 62443-4-2 technical security requirements across all Foundational Requirements and target Security Levels.
- Component security requirements specification
- FR/SL gap analysis
- Compensating control recommendations
STRIDE Threat Modeling
Structured threat analysis of your industrial device using the STRIDE methodology. We identify threats across Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege — and derive security requirements from the findings.
- Data flow diagrams and trust boundaries
- STRIDE threat register
- Security requirements derived from threats
Security Implementation in Devices
Hands-on support for implementing security controls directly into your device firmware and software. We work with your development team to integrate authentication, access control, secure communication, and logging — correctly and efficiently.
- Security architecture for the device
- Implementation guidance per control
- Security verification test cases
How We Work
A structured process from scoping to verified security implementation.
Scope & Context
Define the component boundary, intended use environment, and target Security Level.
Threat Modeling
STRIDE analysis to identify threats, attack vectors, and required mitigations.
Requirements
Derive security requirements from threat findings and 4-2 Foundational Requirements.
Implementation
Hands-on support implementing security controls into your device.
Verification
Test and verify that implemented controls meet the specified requirements.
