What happens during the Develop & Implement phase of ICS security implementation? - answer - Countermeasures are implemented to meet the Target Security Level (SL-T). What is the primary goal of the Maintain phase in ICS security implementation? - answer - To ensure the Achieved Security Level (SL-A) is equal to or better than the Target Security Level (SL-T).* What is phase 1 of the IACS Cybersecurity Life Cycle? - answer - Assess What is phase 2 of the IACS Cybersecurity Life Cycle? - answer - Develop & Implement What is phase 3 of the IACS Cybersecurity Life Cycle? - answer - Maintain phase What is step 1 of the IACS Cybersecurity Life Cycle (Assess Phase)? - answer - High-Level Cyber Risk Assessment What is step 2 of the IACS Cybersecurity Life Cycle (Assess Phase)? - answer - Allocation of IACS Assets to Security Zones or Conduits What is step 3 of the IACS Cybersecurity Life Cycle (Assess Phase)? - answer - Detail Cyber Risk Assessment What is step 4 of the IACS Cybersecurity Life Cycle (Develop & Implement Phase)? - answer - Cybersecurity Requirements Specification What is step 5 of the IACS Cybersecurity Life Cycle (Develop & Implement Phase)? - answer - Design and engineering of Cybersecurity countermeasures What is step 6 of the IACS Cybersecurity Life Cycle (Develop & Implement Phase)? - answer - Installation, commissioning and validation of Cybersecurity countermeasures What is step 7 of the IACS Cybersecurity Life Cycle (Maintain)? - answer - Cybersecurity Maintenance, Monitoring and Management of Change What is step 8 of the IACS Cybersecurity Life Cycle (Maintain)? - answer - Cyber Incident Response & Recovery What are the continuous processes activities of the IACS Cybersecurity Life Cycle? - answer - Cybersecurity Management System: Policies, Procedures, Training & Awareness, Periodic Cybersecurity Audits What must be done before an assessment can be started? - answer - Create a Project Plan ID Steps of the Project to perform the assessment ID the System Under Assessment System Under Consideration (SUC) - answer - The system or systems within an Industrial Automation and Control System environment that are being evaluated or designed for security enhancements. System Under Assessment (SUA) - answer - The system that is being evaluated for compliance with standards. What are some required information gathering items before the assessment can begin? - answer - Goals of the Assessment IACS asset inventory Understanding of the IACS Regulations, requirements, and governance of relevance (Government, Industry, Company) Architecture diagrams Configuration Files Known vulnerabilities Define roles and responsibilities Establish training requirements System Architecture Diagrams - answer - Depiction of system components, their connectivity, and physical locations. Physical System Architecture Diagram - answer - A diagram that provides a visual representation of the physical components within a system and their interconnections. It focuses on hardware elements such as servers, network devices, control systems, and terminals, showing how these components are arranged and connected. Functional System Architecture Diagram - answer - A diagram that describes the functions of a system and their relationships without focusing on physical details. It presents a logical view of the system, emphasizing software elements, data flows, and interactions between different functions or modules within the system. (True/False) IACS functionality should be graphically represented on at least one IACS Architecture drawing - answer - True ISA-95 Functional Layer Level 0 - answer - The physical process — This level defines the physical processes showing data flowin
