NEW QUESTION # 210
What is a key activity in the Maintain phase?

Answer: A

Explanation:
The "Maintain" phase is the fourth phase of the IACS Cybersecurity Lifecycle described in ISA/IEC 62443-2-
1. A key activity in this phase is managing changes (also known as "change management"). This activity ensures that any modifications to the IACS environment (hardware, software, processes, etc.) are evaluated for cybersecurity impact, and proper controls are implemented to maintain the intended security posture.
While risk assessment is typically done in the Assess phase, and allocating assets and designing countermeasures belong to earlier phases, managing changes is essential for ensuring ongoing compliance and effectiveness of cybersecurity controls over time.
Reference: ISA/IEC 62443-2-1:2009, Section 5.6 (Maintain Phase), Table 3 (CSMS lifecycle activities).
