About the ISA/IEC 62443 standards
achievable model to handle risks and mitigate cybersecurity threats.
IEC 62443 is the standard for protecting Industrial Automation and Control Systems and the most effective Cybersecurity solution for Industry 4.0.
With increased connectivity of production assets (IIoT), new hazards emerge that must be included in traditional risk management processes.
An industrial automation control system component manufacturer (supplier) shall include the consideration of security requirements under IEC 62443 4-1 in its product development processes.
The IEC 62443 standard Part 4-1 defines a secure development lifecycle to create and maintain secure products used in industrial automation and control systems (IACS). The IEC 62443-4-1 certificate confirms that the developer has implemented a secure-by-design methodology from the first day of product development processes, which includes a complete security lifecycle and patch management.

PRODUCT
ISA/IEC 62443 series of standards were created to provide an easy-to-use, achievable model to handle risks and mitigate cybersecurity threats.
To make sure that the security requirements relevant to customers are met, these industrial components shall be certified under IEC 62443-4-2. If component suppliers follow the set of guidelines that are defined in the IEC 62443-4-2 subsection, they will equip their customers with the best chance of protecting their networks against cyberattacks.
Although the component suppliers must add certain features and capabilities to their devices for the devices to be suitable for deployment on Industrial IoT networks, conforming to the requirements outlined within IEC 62443-4-2 guarantees secure and resilient components, which are to be procured by 62443 certified and secured IACS organizations.

Key distinctions between IEC 62443-4-1 and IEC 62443-4-2
IEC 62443-4-1 utilizes four maturity levels, whereas IEC 62443-4-2 is structured around four security levels.
Attaining IEC 62443-4-1 certification is a prerequisite for obtaining certification in IEC 62443-4-2.
IEC 62443-4-1 concentrates on secure product development and the product lifecycle, while IEC 62443-4-2 emphasizes technical security requirements for IACS components, specifically embedded devices, network components, host components, and software applications.
IEC 62443-4-1 encompasses 47 requirements distributed across 8 practices, whereas IEC 62443-4-2 addresses 140 requirements outlined in the standard.
The IEC 62443 standard describes 4 levels of security functionality
for component security (62443-4-2)
SL1
Protection against causal or coincidental violation
SL2
Protection against intentional violation using simple means with low resources, generic skills and low motivation
SL3
Protection against intentional violation using sophisticated means with moderate resources, IACS specific skills and moderate motivation
SL4
Protection against intentional violation using sophisticated means with extended resources, IACS specific skills and high motivation
What documents are required during the evaluation?
At the commencement of the process, the client needs to specify the desired level of maturity (4-1) or security level (4-2) for the product evaluation. Various documents are also necessary, with some to be provided by the client, others by the laboratory, and only one by the Certification Body (CB). Following this, the client is required to draft a Conformity Statement, detailing how the requirements are met.
After the evaluation, the lab completes theTest Report Form (TRF) using information from the customer. The TRF serves as the outcome of the evaluation and is submitted to the CB. The CB assumes responsibility for issuing the certificate.

Testimonials
Kenneth Lasoski
Versa Networks
Evaluation team was extremely reasonable and flexible with resolution to findings and was helpful in finding agreeable solutions for CB comments. Consultation team was always responsive and helped shape the documentation for easier evaluation, and provided useful recommendations on satisfying SFR/SARs.
Thierry Bonda
Landis+Gyr
CCLab was well prepared, flexible during the whole evaluation process, and supported us with continuous communication and guidance. Many lessons were learnt during the project and CCLab has always been looking for solutions, supporting our developers the best way they could. The new Swiss evaluation methodology was a good and professional basis to work with, but both parties had to learn how to deal with it.

It was a well-managed project which achieved success in an effortless manner.
Kalev Pihl
SK ID Solutions
We needed a lab that works quickly but with high work morale and quality of work. CCLab is exactly like that! It was good cooperation experience to work with them. The project was rather complex and our expectations maybe even too high, but the team was committed to the common goals and could keep the milestones; therefore we were able to deliver what was needed. I highly recommend CCLab team to anyone for their great team spirit, quality orientations, agility and reasonable pricing.
