You are a cybersecurity analyst at a power plant. After running a vulnerability scan on the system, you find several potential vulnerabilities. What is the most appropriate first step to ensure the security of the system?
Apply relevant patches based on assessment findings
Evaluate all identified vulnerabilities
Consider disabling affected systems if necessary
Conduct a risk assessment to evaluate vulnerabilities
The most appropriate first step in ensuring the security of a SCADA (Supervisory Control and Data Acquisition) system after identifying potential vulnerabilities is to conduct a risk assessment. This involves understanding the criticality of the identified vulnerabilities in the context of the overall system operations, potential impacts, and existing mitigations. Patching or updating the system without thorough analysis could disrupt operations and lead to unintended consequences.
