The standard ISA 62443-2-1 belongs to the Policies and Procedures tier/group of the ISA 99 committee work product. ISA 62443 (formerly known as ISA 99) is a series of standards, technical reports, and related information that define procedures for implementing electronically secure Industrial Automation and Control Systems (IACS). The standards are grouped into four general categories: 1) General (Concepts & Models): Provides an overview and foundational concepts. 2) Policies and Procedures: Focuses on security policies, procedures, and practices for IACS. 3) System: Addresses requirements at the system level. 4) Component: Focuses on requirements for individual system components. ISA 62443-2-1, titled "Security for Industrial Automation and Control Systems: Establishing an Industrial Automation and Control Systems Security Program," specifically falls under the Policies and Procedures category. This standard provides guidance on establishing and managing a cybersecurity management system (CSMS) for IACS, ensuring that policies, procedures, and practices are in place to manage security risks effectively.
