Which is a key element in the system development and maintenance process?

Assessing the risks of changing the Industrial Automation and Control Systems (IACS) is a crucial part of the system development and maintenance process. This step ensures that any modifications or updates to the system do not inadvertently introduce vulnerabilities or disrupt the integrity and availability of the system. It helps organizations identify potential threats or weaknesses that could be exploited, allowing for the implementation of appropriate mitigations prior to any changes. In the context of cybersecurity, understanding the risks associated with changes is vital for maintaining a secure and resilient system.

The other options, while important in various contexts, do not specifically address core aspects of system development and maintenance related to cybersecurity. Establishing and maintaining social media accounts does not relate to the technical aspects of system security. Market research analysis may provide insights for product development but is not directly involved in ensuring the security or integrity of IACS. Client feedback evaluation is valuable for improving user experience and satisfaction but does not primarily focus on the technical and security implications of system changes.
