Standards Development
This European Standard provides a security profile for routers, modems intended for the connection to the internet, and switches. It provides a defined subset of IEC 62443 requirements applicable to routers, internet-connected modems, and switches that are intended to be used in OT environments.
The Cyber Resilience Act (CRA) lists routers, modems intended for the connection to the internet, and switches in its Annex III “important products with digital elements”, under Class 1. This is why manufacturers require harmonized standards covering this product category to facilitate the placing of corresponding products in the EU market after the CRA date of applicability. Hence, the development of harmonized standards for routers, internet-connected modems, and switches is explicitly requested in the CRA standardization request. In an OT environment, routers, internet-connected modems, and switches have specific requirements and needs that differ from IT environments. This is why, CLC/TC 65X proposes to standardize routers, internet- connected modems, and switches that are intended to be used in OT environments, following IEC TS 62443-1-5 which is the scheme for the development of IEC 62443 security profiles. This project is proposed as a preliminary work item (PWI) for the following reasons: • The target dates for the development of this standard are not known yet, as the priority is given to the modifications of EN IEC 62443-4-2 in support of the CRA standardization request. The aim is to activate this PWI in a later stage. • It is however important to list this project in CLC/TC 65X work programme as a PWI to inform relevant stakeholders (European Commission, economic operators) about CLC/TC 65X intentions. Note: this PWI corresponds to the item 27 of the CRA standardization request, Annex I (M/606)
