= The most important reason to ensure information security is aligned with the organization’s strategy is to optimize security risk management. Information security is not an isolated function, but rather an integral part of the organization’s overall objectives, processes, and governance. By aligning information security with the organization’s strategy, the information security manager can ensure that security risks are identified, assessed, treated, and monitored in a consistent, effective, and efficient manner1. Alignment also enables the information security manager to communicate the value and benefits of information security to senior management and other stakeholders, and to justify the allocation of resources and investments for security initiatives2. Alignment also helps to establish clear roles and responsibilities for information security across the organization, and to foster a culture of security awareness and accountability3. Therefore, alignment is essential for optimizing security risk management, which is the process of balancing the protection of information assets with the business objectives and risk appetite of the organization4. References = 1: CISM Exam Content Outline | CISM Certification | ISACA 2: CISM_Review_Manual Pages 1-30 - Flip PDF Download | FlipHTML5 3: CISM 2020: Information Security & Business Process Alignment 4: CISM Review Manual 15th Edition, Chapter 2, Section 2.1

 A snapshot is a point-in-time copy of the state of a virtual machine (VM) that can be used to restore the VM to a previous state in case of a security incident or a disaster. A snapshot can capture the VM’s disk, memory, and device configuration, allowing for a quick and easy recovery of the VM’s data and functionality. Snapshots can also be used to create backups, clones, or replicas of VMs for testing, analysis, or migration purposes. Snapshots are a common service offering in Infrastructure as a Service (IaaS) models, where customers can provision and manage VMs on demand from a cloud service provider (CSP). A CSP that offers the capability to take snapshots of VMs can assist customers when recovering from a security incident by providing them with the following benefits12:

Faster recovery time: Snapshots can reduce the downtime and data loss caused by a security incident by allowing customers to quickly revert their VMs to a known good state. Snapshots can also help customers avoid the need to reinstall or reconfigure their VMs after an incident, saving time and resources.

Easier incident analysis: Snapshots can enable customers to perform online or offline analysis of their VMs after an incident, without affecting the production environment. Customers can use snapshots to examine the VM’s disk, memory, and logs for evidence of compromise, root cause analysis, or forensic investigation. Customers can also use snapshots to test and validate their incident response plans or remediation actions before applying them to the production VMs.

Enhanced security posture: Snapshots can improve the security posture of customers by enabling them to implement best practices such as backup and restore, disaster recovery, and business continuity. Snapshots can help customers protect their VMs from accidental or malicious deletion, corruption, or modification, as well as from environmental or technical disruptions. Snapshots can also help customers comply with regulatory or contractual requirements for data retention, availability, or integrity. References = What is Disaster Recovery as a Service? | CSA - Cloud Security Alliance, What Is Cloud Incident Response (IR)?

 According to the CISM Review Manual, the information security manager’s best course of action when security controls may no longer be adequate due to changes in the organization’s environment is to perform a new risk assessment. A risk assessment is a process of identifying, analyzing, and evaluating the risks that affect the organization’s information assets and business processes. A risk assessment should be performed periodically or whenever there are significant changes in the organization’s environment, such as new threats, vulnerabilities, technologies, regulations, or business objectives. A risk assessment helps to determine the current level of risk exposure and the adequacy of existing security controls. A risk assessment also provides the basis for developing or updating the risk treatment plan, which defines the appropriate risk responses, such as implementing new or enhanced security controls, transferring the risk to a third party, accepting the risk, or avoiding the risk.

The other options are not the best course of action in this scenario. Reviewing the previous risk assessment and countermeasures may not reflect the current state of the organization’s environment and may not identify new or emerging risks. Evaluating countermeasures to mitigate new risks may be premature without performing a new risk assessment to identify and prioritize the risks. Transferring the new risk to a third party may not be feasible or cost-effective without performing a new risk assessment to evaluate the risk level and the available risk transfer options.
