Explanation
The first step when a new vulnerability is identified is to re-evaluate the risk associated with the vulnerability.
This may require an update to the risk assessment and the implementation of additional controls. Informing senior management of the vulnerability is important, but should not be the first step. Implementing compensating controls may also be necessary, but again, should not be the first step. Asking the business owner for a remediation plan may be useful, but only after the risk has been re-evaluated.
The information security manager should first re-evaluate the risk posed by the new vulnerability to determine its impact and likelihood. Based on this assessment, appropriate actions can be taken such as informing senior management, implementing compensating controls, or requesting a remediation plan from the business owner.
The other choices are possible actions but not necessarily the first one.
A vulnerability is a weakness that can be exploited by an attacker to compromise a system or network2. A vulnerability can affect key data processing systems within an organization if it exposes sensitive information, disrupts business operations, or damages assets2. A vulnerability assessment is a process of identifying and evaluating vulnerabilities and their potential consequences2
