The CISO should first determine the extent of the impact to the organization by assessing the nature and scope of the data breach, the type and sensitivity of the data involved, the potential harm to the organization and its customers, and the legal and contractual obligations of the organization and the service provider. This will help the CISO to prioritize the appropriate actions and resources to respond to the incident and mitigate the risks. The other options are possible actions that the CISO may take after determining the impact, depending on the circumstances and the outcomes of the investigation. References = CISM Review Manual 15th Edition, page 2231; CISM Review Questions, Answers & Explanations Database - 12 Month Subscription, Question ID: 1030

 A business impact analysis (BIA) is the process of identifying and evaluating the potential effects of disruptions to critical business functions or processes. A BIA helps to determine the recovery priorities, objectives, and strategies for the organization in the event of a disaster or crisis. A BIA also helps to identify the worst-case disruption scenarios, which are the scenarios that would cause the most severe impact to the organization in terms of financial, operational, reputational, or legal consequences. By conducting a BIA, the organization can assess the likelihood and impact of various disruption scenarios, and plan accordingly to mitigate the risks and ensure business continuity and resilience. References = CISM Review Manual 15th Edition, page 181, page 183.

Creating an inventory is the FIRST step in developing an asset classification program because it helps to identify and list all the information systems assets of the organization that need to be protected and classified. An inventory should include the asset name, description, owner, custodian, location, type, value, and other relevant attributes. Creating an inventory also enables the establishment of the ownership and custody of the assets, which are essential for defining the roles and responsibilities for asset protection and classification12. Categorizing each asset (A) is a subsequent step in developing an asset classification program, after creating an inventory. Categorizing each asset involves assigning a security level or category to each asset based on its value, sensitivity, and criticality to the organization. The security level or category determines the protection level and controls required for each asset12. Creating a business case for a digital rights management tool © is not a step in developing an asset classification program, but rather a possible outcome or recommendation based on the asset classification results. A digital rights management tool is a type of control that can help to enforce the security policies and objectives for the classified assets, such as preventing unauthorized access, copying, or distribution of the assets3. Implementing a data loss prevention (DLP) system (D) is also not a step in developing an asset classification program, but rather a possible outcome or recommendation based on the asset classification results. A DLP system is a type of control that can help to monitor, detect, and prevent the loss or leakage of the classified assets, such as through email, web, or removable media4. References = 1: CISM Review Manual 15th Edition, page 77-781; 2: IT Asset Valuation, Risk Assessment and Control Implementation Model - ISACA2; 3: What is Digital Rights Management? - Definition from Techopedia3; 4: What is Data Loss Prevention (DLP)? - Definition from Techopedia4

Performing frequent backups and storing them offline is the best way to reduce the impact of a successful ransomware attack, as this allows the organization to restore its data and systems without paying the ransom or losing valuable information. Purchasing or renewing cyber insurance policies may help cover some of the costs and losses associated with a ransomware attack, but it does not prevent or mitigate the attack itself. Including provisions to pay ransoms in the information security budget may encourage more attacks and does not guarantee the recovery of the data or the removal of the malware. Monitoring the network and providing alerts on intrusions may help detect and respond to a ransomware attack, but it does not reduce the impact of a successful attack that has already encrypted or exfiltrated the data. References = CISM Review Manual 2023, page 1661; CISM Review Questions, Answers & Explanations Manual 2023, page 312; CISM Exam Overview - Vinsys3
