SIS risk assessment principles
Understanding cybersecurity risk within ICSs and SISs involves acknowledging the interplay between threats, vulnerabilities, impacts, and consequences. A threat represents a potential source of harmful actions that could affect system operations, arising from various sources such as natural disasters, malicious attacks, or human errors. Vulnerabilities are weaknesses in a system that can be exploited by threats, potentially disrupting normal operations. Impacts represent the consequences of these threats exploiting vulnerabilities, which can range from minor system disruptions to significant safety incidences.
Risk assessment plays a pivotal role in a Cybersecurity Management System (CSMS). It provides a basis for understanding cyber risks associated with an organization’s ICS, including the SIS. Through identification, analysis, and evaluation, risk assessments help to devise strategies that efficiently mitigate these risks, protecting the...
