A technical vulnerability is a weakness or flaw in the design or implementation of an information system or resource that can be exploited or compromised by a threat or source of harm that may affect the organization’s objectives or operations. A technical vulnerability may be caused byvarious factors, such as human error, system failure, process inefficiency, resource limitation, etc.
A vulnerability assessment is a process of identifying and evaluating the technical vulnerabilities that exist or may arise in the organization’s information systems or resources, and determining their severity and impact. A vulnerability assessment can help the organization to assess and prioritize the risks, and to design and implement appropriate controls or countermeasures to mitigate or prevent the risks.
The best response to the scenario of a recently discovered technical vulnerability being actively exploited is to conduct a vulnerability assessment, because it can help the organization to address the following questions:
What is the nature and extent of the technical vulnerability, and how does it affect the functionality or security of the information system or resource?
How is the technical vulnerability being exploited or compromised, and by whom or what?
What are the potential consequences or impacts of the exploitation or compromise of the technical vulnerability for the organization and its stakeholders?
How can the technical vulnerability be detected and reported, and what are the available or feasible options or solutions to address or correct it?
Conducting a vulnerability assessment can help the organization to improve and optimize the information system or resource quality and performance, and to reduce or eliminate the technicalvulnerability. It can also help the organization to align the information system or resource with the organization’s objectives and requirements, and to comply with the organization’s policies and standards.
The other options are not the best responses to the scenario of a recently discovered technical vulnerability being actively exploited, because they do not address the main purpose and benefit of conducting a vulnerability assessment, which is to identify and evaluate the technical vulnerability, and to determine its severity and impact.
Assessing the vulnerability management process is a process of evaluating and verifying the adequacy and effectiveness of the process that is used to identify, analyze, evaluate, and communicate the technical vulnerabilities, and to align them with the organization’s objectives and requirements. Assessing the vulnerability management process can help the organization to improve and optimize the process, and to reduce or eliminate the gaps or weaknesses in the process, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.
Conducting a control self-assessment is a process of evaluating and verifying the adequacy and effectiveness of the controls that are intended to ensure the confidentiality, integrity, availability, and reliability of the information systems and resources, using the input and feedback from the individuals or groups that are involved or responsible for the information systems activities or functions. Conducting a control self-assessment can help the organization to identify and document the control deficiencies, and to align them with the organization’s objectives and requirements, but it is not the best response to the scenario, because it does not indicate thenature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.
Reassessing the inherent risk of the target is a process of reevaluating and recalculating the amount and type of risk that exists in the absence of any controls, and that is inherent to the nature or characteristics of the target, which is the information system or resource that is affected by the technical vulnerability. Reassessing the inherent risk of the target can help the organization to understand and document the risk exposure or level, and to align it with the organization’s risk appetite and tolerance, but it is not the best response to the scenario, because it does not indicate the nature and extent of the technical vulnerability, and how it affects the organization and its stakeholders.
