Explanation: The first course of action for the CIO of an enterprise to help plan for the possibility of ransomed corporate data should be to request a targeted risk assessment. This is because a targeted risk assessment can help to identify and evaluate the specific threats, vulnerabilities, and impacts of ransomware attacks on the enterprise’s data and systems. A targeted risk assessment can also help to determine the likelihood and severity of ransomware incidents, as well as the appropriate controls and mitigation strategies to reduce the risk to an acceptable level.
Requiring development of key risk indicators (KRIs) is not the first course of action, as it is a monitoring tool for measuring the risk exposure and performance. KRIs are metrics that provide information on the current level and trend of risk in relation to the risk appetite and tolerance of the enterprise. KRIs can help to track and report the progress and effectiveness of the risk management activities, as well as alert the management of any potential issues or changes that may affect the risk profile. However, requiring development of KRIs does not provide a comprehensive analysis or improvement plan for ransomed corporate data.
Developing a policy to address ransomware is not the first course of action, as it is a result of conducting a targeted risk assessment. A policy to address ransomware is a document that defines the rules, guidelines, and responsibilities for preventing, detecting, responding to, and recovering from ransomware attacks. Developing a policy to address ransomware can help to communicate the expectations and requirements for ransomware protection and compliance, as well as enforce accountability and governance for ransomware incidents. However, developing a policy to address ransomware does not provide a detailed assessment or guidance for ransomed corporate data.
Backing up corporate data to a secure location is not the first course of action, as it is an implementation step after conducting a targeted risk assessment and developing a policy to address ransomware. Backing up corporate data to a secure location can help to preserve the availability, integrity, and confidentiality of the data in case of a ransomware attack. Backing up corporate data to a secure location can also help to restore the data and resume normal operations after a ransomware attack. However, backing up corporate data to a secure location does not provide a thorough risk analysis or governance framework for ransomed corporate data.
