Benefit from Limes Security's extensive IEC 62443 experience towards compliance or even certification.
As digitalization and automation progress, so do the risks for industrial companies. Every new connection, every additional system and every interface can be a gateway for cyber attacks. Production downtime, security incidents and reputational damage are therefore among the greatest threats to critical infrastructures and manufacturing companies.
The IEC 62443 series of standards provides an internationally recognized framework for managing these risks in a targeted manner. It combines technical measures with organizational processes and thus creates the basis for greater security, resilience and trust. Companies that rely on IEC 62443 not only protect their systems, but also their future capabilities in global competition.
Creation of an individual security roadmap for the long-term implementation of IEC 62443 in the company.
Implementation of penetration tests, threat analyses and architecture reviews especially for industrial control systems and components.
Support in preparing for audits and certifications in accordance with IEC 62443, including documentation, process support and pre-audits.
Advice on how to apply IEC 62443 correctly in tenders and customer projects – for operators, integrators and manufacturers.
IEC 62443 is an internationally established and recognized series of standards for cyber security in industrial networks and systems. It describes how manufacturers, system integrators and operators can jointly develop and operate secure products, systems and processes.
The parts of the IEC 62443-1-x series form the basic framework of the standards series. They provide the terms, concepts and models on which all other parts are based. These include
IEC 62443-1-1 → Terms, definitions, models
IEC 62443-1-2 → Master Glossary
IEC 62443-1-3 → System-Security-Conformity Metrics
IEC 62443-1-4 → IACS Security Lifecycle and Use Cases
Defines requirements for the introduction and maintenance of a cybersecurity management system (CSMS) for asset owners (operators of industrial plants). Contains specifications on guidelines, organization, risk management, operation, incident handling and continuous improvement.
Defines requirements for service providers and system integrators who design, implement or maintain industrial automation and control systems. The aim is to ensure a standardized, secure approach by external partners in line with operator requirements.
Describes how a system under consideration (SUC) is defined, divided into zones and conduits and analyzed with regard to risks. On this basis, target security levels (SL-T) are derived and security requirements are documented.
Defines specific system requirements (SRs) for the implementation of security in industrial systems and associated security levels (SL-C). The basis is the concept of the seven foundational requirements (e.g. authentication, integrity, availability).
Specifies requirements for a secure product development process (SDL). This includes guidelines for design, implementation, verification, vulnerability management, patch management and handling the end-of-life of products.
Defines technical security requirements for individual components such as control systems, HMI, network devices or software. These component requirements (CRs) are based on the system requirements (IEC 62443-3-3) and address the seven foundational requirements.
