What is the assessment of the criticality of an IACS asset referred to as?

The assessment of the criticality of an Industrial Automation and Control System (IACS) asset is referred to as a Cyber Security Criticality Assessment. This type of assessment specifically focuses on evaluating the importance and vulnerability of assets within the context of cybersecurity. It involves identifying which assets are essential for maintaining operations and how their potential compromise could impact the overall system's safety and security.

A Cyber Security Criticality Assessment ensures that organizations can prioritize their cybersecurity efforts effectively, focusing on the most critical assets that require heightened protection and mitigation strategies. This assessment is crucial because it helps in resource allocation and in developing appropriate defenses against threats that specifically target key operational components.

In contrast, terms like Asset Risk Assessment and Critical Asset Inventory are broader concepts that may not specifically focus on the cyber security aspects of criticality. Infrastructure Analysis, while important, typically deals with the general study of infrastructure systems and their components rather than the specialized focus on cybersecurity criticality within IACS. Therefore, identifying the assessment specifically as a Cyber Security Criticality Assessment aligns best with the understanding of how critical IACS assets are evaluated in the context of cybersecurity.
