Which of the following should be determined FIRST when a new security vulnerability is made...

 When a new security vulnerability is made public, the first step is to determine whether the affected technology is used within the organization. This will help to assess the impact and exposure of the vulnerability on the organization’s assets, processes, and objectives. If the affected technology is not used within the organization, then the vulnerability does not pose a direct threat and no further action is required. However, if the affected technology is used within the organization, then the next steps are to identify the systems and components that are vulnerable, evaluate the severity and likelihood of the vulnerability being exploited, and implement appropriate mitigating controls or remediation actions. References = Risk and Information Systems Control Study Manual, Chapter 5, Section 5.3.2.1, p. 240-241
