 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, a business impact analysis (BIA) is the most useful tool when determining the business continuity strategy for a large organization’s data center, as it helps to identify and prioritize the critical business processes and resources that depend on the data center, and the impact of their disruption or loss. A BIA also provides the basis for defining the recovery time objectives (RTOs) and recovery point objectives (RPOs) for the data center, which guide the selection of the appropriate business continuity strategy.

The first step when developing a business case for a new intrusion detection system (IDS) solution is to define the issues to be addressed. A business case is a document that provides the rationale and justification for initiating a project or investment. It typically includes information such as the problem statement, the objectives, the alternatives, the costs and benefits, the risks and assumptions, and the expected outcomes. The first step in developing a business case is to define the issues to be addressed, which means identifying and describing the current situation, the problems or challenges faced by the organization, and the needs or opportunities for improvement. By defining the issues to be addressed, the information security manager can establish the scope and purpose of the business case, and provide a clear and compelling problem statement that explains why a new IDS solution is needed. The other options are not the first step when developing a business case for a new IDS solution, although they may be part of the subsequent steps. Performing a cost-benefit analysis is a step that involves comparing the costs and benefits of different alternatives, including the new IDS solution and the status quo. A cost-benefit analysis can help evaluate and justify the feasibility and desirability of each alternative, and support the decision-making process. Calculating the total cost of ownership (TCO) is a step that involves estimating the direct and indirect costs associated with acquiring, operating, maintaining, and disposing of an asset or a system over its entire life cycle. A TCO calculation can help determine the long-term financial implications of investing in a new IDS solution, and compare it with other alternatives. Conducting a feasibility study is a step that involves assessing the technical, operational, legal, and economic aspects of implementing a project or an investment. A feasibility study can help identify and mitigate any potential issues or risks that may affect the success of the project or investment, and provide recommendations for improvement

A balanced scorecard enables information security governance by providing a framework for aligning security objectives with business goals and measuring performance against them. The other choices are not directly related to governance but may be supported by it.

A balanced scorecard is a strategic management tool that describes the cause-and-effect linkages between four high-level perspectives of strategy and execution: financial, customer, internal process, and learning and growth2. It helps organizations communicate and monitor their vision and strategy across different levels and functions2.

Performing a risk assessment gives a holistic and objective understanding of the threats, vulnerabilities, and controls across the organization. It reveals actual risk exposures and the effectiveness of current controls, which directly reflect the organization’s security posture.

“Risk assessments identify and evaluate risk and provide the basis for determining how those risks should be managed and mitigated.”

— CISM Review Manual 15th Edition, Chapter 2: Risk Management, Section: Risk Assessment

According to ISACA’s CISM Practice Question Database, performing a risk assessment is prioritized over reviewing documents or conducting interviews because it offers direct insight into current exposures and control effectiveness.

 The information security manager’s first course of action should be to validate the relevance of the information received from the threat intelligence service. This means verifying the source, credibility, accuracy, and timeliness of the information, as well as assessing the potential impact and likelihood of the threat for the organization. This will help the information security manager to determine the appropriate response and prioritize the actions to mitigate the threat. Conducting an information security audit, performing a gap analysis, and informing senior management are possible subsequent actions, but they are not the first course of action. An information security audit is a systematic and independent assessment of the effectiveness of the information security controls and processes. A gap analysis is a comparison of the current state of the information security program with the desired state or best practices. Informing senior management is a communication activity that should be done after validating the information and assessing the risk. References = CISM Review Manual, 16th Edition, pages 44-451; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 632

The first step the information security manager should take upon learning of the potential threat is to validate the relevance of the information. This should involve researching the threat to evaluate its potential impact on the organization and to determine the accuracy of the threat intelligence. Once the information is validated, the information security manager can then take action, such as informing senior management, conducting an information security audit, or performing a gap analysis.

A gap analysis is a tool that helps to identify the current state of compliance and the desired state of compliance, as well as the actions needed to achieve the desired state. A gap analysis should be done before implementing any specific controls or solutions, such as encryption, data minimization, or ROI analysis.

The best step to address the situation of losing a smartphone that contains sensitive information is to remotely wipe the device, which means erasing all the data on the device and restoring it to factory settings. Remotely wiping the device can prevent unauthorized access to the sensitive information and protect the organization from data breaches or leaks. Remotely wiping the device can be done through services such as Find My Device for Android or Find My iPhone for iOS, or through mobile device management (MDM) solutions. The other options, such as disabling the user’s access, terminating the device connectivity, or escalating to the user’s management, may not be effective or timely enough to secure the sensitive information on the device.

Conducting awareness training across the organization is the best way to reduce the risk of security incidents from targeted email attacks because it helps to educate and empower the employees to recognize and avoid falling for such attacks. Targeted email attacks, such as phishing, spear phishing, or business email compromise, rely on social engineering techniques to deceive and manipulate the recipients into clicking on malicious links, opening malicious attachments, or disclosing sensitive information. Awareness training can help to raise the level of security culture and behavior among the employees, as well as to provide them with practical tips and best practices to protect themselves and the organization from targeted email attacks. Therefore, conducting awareness training across the organization is the correct answer.

A balanced scorecard is a tool that can be used to demonstrate the added value of an information security program by measuring and reporting on key performance indicators (KPIs) and key risk indicators (KRIs) aligned with strategic objectives. Security baselines, a gap analysis and a SWOT analysis are all useful for assessing and improving security posture, but they do not necessarily show how security contributes to business value.

Potential business loss is the most important factor to consider when determining asset valuation, as it reflects the impact of losing or compromising the asset on the organization’s objectives and operations. Asset recovery cost, asset classification level, and cost of insurance premiums are also relevant, but not as important as potential business loss, as they do not capture the full value of the asset to the organization. References = CISM Review Manual 2023, page 461; CISM Review Questions, Answers & Explanations Manual 2023, page 292

The most important consideration when developing key performance indicators (KPIs) for the information security program is B. Alignment with business initiatives. This is because KPIs are measurable values that demonstrate how effectively the information security program is achieving its objectives and delivering value to the organization. KPIs should be aligned with the business initiatives, such as the strategic goals, the mission, the vision, and the values of the organization, and support the achievement of the desired outcomes and benefits. KPIs should also reflect the needs, expectations, and challenges of the business stakeholders, and provide relevant, meaningful, and actionable information for decision making and improvement. KPIs should not be too technical, complex, or ambiguous, but rather focus on the key aspects of information security performance, such as risk, compliance, maturity, value, and effectiveness.

KPIs are measurable values that demonstrate how effectively the information security program is achieving its objectives and delivering value to the organization. KPIs should be aligned with the business initiatives, such as the strategic goals, the mission, the vision, and the values of the organization, and support the achievement of the desired outcomes and benefits.

The primary objective of implementing standard security configurations is to control vulnerabilities and reduce threats from changed configurations. Standard security configurations are the baseline settings and parameters that define the desired security level and functionality of information systems and devices. By implementing standard security configurations, the organization can ensure that the information systems and devices are configured in a consistent and secure manner, and that any deviations or changes from the standard are detected and corrected. This can help to prevent or mitigate potential security incidents caused by misconfigurations, unauthorized modifications, or malicious attacks.

The BEST way for an organization to ensure that incident response teams are properly prepared is by conducting tabletop exercises appropriate for the organization.

Tabletop exercises are an effective way to test and validate an organization's incident response plan (IRP) and the readiness of the incident response team. These exercises simulate different scenarios in a controlled environment and allow the team to practice their response procedures, identify gaps, and make improvements to the plan. By conducting regular tabletop exercises, the incident response team can stay current with changes in the threat landscape and ensure that they are prepared to respond to incidents effectively.

According to the Certified Information Security Manager (CISM) Study Manual, "Tabletop exercises are a valuable tool for testing and validating the effectiveness of the IRP and the readiness of the incident response team. These exercises simulate different scenarios in a controlled environment and allow the team to practice their response procedures, identify gaps, and make improvements to the plan."

While providing training from third-party forensics firms, obtaining industry certifications, and documenting multiple scenarios for the organization and response steps can all be useful in preparing incident response teams, they are not as effective as conducting tabletop exercises appropriate for the organization.
