How can geographical factors influence cybersecurity risk assessments for IACS?

Geographical factors significantly influence cybersecurity risk assessments for Industrial Automation and Control Systems (IACS) primarily by impacting physical security and accessibility. The physical location of infrastructure can dictate how secure a facility is against unauthorized access or physical threats, such as natural disasters, vandalism, or theft. For example, systems located in remote areas may have limited physical security measures and are more susceptible to intrusion or damage, while urban systems might face different threats related to their environment.

Additionally, geographical considerations can determine access routes for both authorized personnel and potential attackers. Facilities in accessible areas may require stronger security measures to mitigate higher risks associated with human threats. As such, assessments that take into account the geographical context will provide a more holistic view of the risks and vulnerabilities an IACS may face, ensuring that both cybersecurity and physical security strategies are aligned for appropriate risk management.

While other options also have relevance, they do not specifically emphasize the direct impact of geographical factors on the security posture of the physical systems involved.
