ISA/IEC 62443-4 for industrial Automation and Control Systems, IACS

What the 62443‑4 standard covers

The 62443‑4 standard has two key parts:

62443‑4‑1 — Secure Product Development Lifecycle Requirements

This part defines the requirements for designing, implementing, verifying, maintaining, and supporting a product throughout its lifecycle.
It includes areas such as:

• Security management
• Requirements specification
• Secure design & implementation
• Verification & validation
• Handling vulnerabilities and updates
• Security guidelines 1

 62443‑4‑2 — Technical Security Requirements for Components

 This defines technical security requirements for four categories of components:

• Software applications
• Embedded devices
• Host devices
• Network devices

Core requirement areas include:

• Identification & authentication
• Control of use
• System integrity
• Data confidentiality
• Data flow control
• Event response
• Resource availability

 Why organizations seek 62443‑4 evaluation

Manufacturers of industrial components (controllers, PLCs, HMIs, networks, etc.) want to demonstrate:

• Compliance with international cybersecurity requirements
• Assurance that their development processes meet security best practices (per 4‑1)
• Proof that their products meet technical security capabilities (per 4‑2)
• Ability to be integrated into secure IACS systems

 These evaluations help customers—especially in critical infrastructure—reduce cybersecurity risk and procurement uncertainty.

 How does RISE do this evaluation

RISE presents the ISA/IEC 62443- 4 series, emphasizing the practical cybersecurity requirements for industrial automation and control system (IACS) components. The RISE course page clarifies the educational framing around 62443- 4 and highlights key concepts useful for a commercial offering, as well as how they guide the secure development, protection, and validation of industrial products throughout their lifecycle. It also clarifies the distinct roles of parts 4.1 and 4.2: 4.1 addresses secure development processes, and 4.2 details the technical security capabilities expected of compliant components.

This perspective creates a strong foundation for shaping an evaluation offering by clearly conveying:

• What the cybersecurity requirements are
• How they are applied to products and components
• Who benefits from meeting these requirements
• Why is secure by design development essential in modern industrial environments

 How does this evaluation help customers?

 It evaluates the component cybersecurity against internationally recognized requirements

• It helps product suppliers demonstrate trustworthiness
• It aligns with industry demand for secure-by-design industrial products
• It supports regulatory and procurement expectations
