The first step in implementing ISO 27001, an international standard for information security management systems (ISMS), is to perform a security risk assessment. This initial step is critical as it helps identify the organization's information assets that could be at risk, assess the vulnerabilities and threats to these assets, and evaluate their potential impacts. This risk assessment forms the foundation for defining appropriate security controls and measures tailored to the organization’s specific needs. Starting with a risk assessment ensures that the security controls implemented are aligned with the actual risks the organization faces, making the ISMS more effective and targeted.ISA/IEC 62443 Cybersecurity Fundamentals References:

• Although ISO 27001 is not part of ISA/IEC 62443, it shares common principles in cybersecurity management by starting with a comprehensive understanding and assessment of security risks, which is a fundamental aspect in both standards for setting up effective security practices.

A security conduit is a logical or physical grouping of communication channels connecting two or more zones that share common security requirements1. A zone is a grouping of systems and components based on their functional, logical, and physical relationship that share common security requirements1. Therefore, a security conduit consists of assets that enable or facilitatecommunication between zones, such as wiring, routers, switches, and network management devices. Controllers, sensors, transmitters, and final control elements are examples of assets that belong to a zone, not a conduit. Ferrous, thickwall, and threaded conduit including raceways are physical structures that may enclose or protect wiring, but they are not part of the communication channels themselves. Power lines, cabinet enclosures, and protective grounds are also not part of the communication channels, but rather provide power or protection to the assets in a zone or a conduit. References: 1: Key Concepts of ISA/IEC 62443: Zones & Security Levels | Dragos
