Restoring the system from a known good backup is the most appropriate eradication method when responding to an incident resulting in malware on an application server, as it ensures that the system is free of any malicious code and that the data and applications are consistent with the expected state. Disconnecting the system from the network may prevent further spread of the malware, but it does not eradicate it from the system. Changing passwords on the compromised system may reduce the risk of unauthorized access, but it does not remove the malware from the system. Performing operation system hardening may improve the security configuration of the system, but it does not guarantee that the malware is eliminated from the system.

The primary basis for establishing metrics that measure the effectiveness of an information security program should be the risk tolerance of the organization, which is the degree of risk that the organization is willing to accept or avoid in pursuit of its objectives. Metrics based on risk tolerance can help to evaluate whether the information security program is aligned with the business strategy, supports the risk management process, and delivers value to the organization. Residual risk, regulatory requirements, and control objectives are also important factors to consider when developing metrics, but they are not as fundamental as the risk tolerance.

Before implementing a BYOD program, it is most important to develop an acceptable use policy that defines the roles and responsibilities of the organization and the employees, the security requirements and controls for the devices, the acceptable and unacceptable behaviors and activities, and the consequences of non-compliance. This policy will help to establish a clear and consistent framework for managing the risks and benefits of BYOD.

The greatest business benefit of an incident response plan is minimizing the negative impact of disruptive incidents on operations and reputation.

“The primary business objective of an incident response plan is to minimize the impact of incidents on business operations and assets.”

— CISM Review Manual 15th Edition, Chapter 4: Incident Management, Section: Incident Response Plan Objectives*

ISACA practice questions reinforce that limiting impact is the key outcome from a business perspective.

 The information security manager’s best course of action is to present the risk to senior management, because this is a case of conflicting objectives and priorities between the information security team and the business management. The information security manager should explain the potential impact and likelihood of a security breach due to the violation of the access policy, as well as the possible legal, regulatory, and reputational consequences. The information security manager should also provide alternative solutions that can achieve both operational efficiency and security compliance, such as implementing single sign-on, role-based access control, or multi-factor authentication. The information security manager should not enforce the policy without senior management’s approval, because this could cause operational disruption and business dissatisfaction. The information security manager should not modify the policy without a proper risk assessment and approval process, because this could weaken the security posture and expose the organization to more threats. The information security manager should not create an exception for the deviation without a formal risk acceptance and documentation process, because this could create inconsistency and ambiguity in the policy enforcement and accountability. References = CISM Review Manual, 16th Edition, ISACA, 2021, pages 127-128, 138-139, 143-144.

The first course of action when one of the organization’s critical third-party providers experiences a data breach is to invoke the incident response plan, which means activating the incident response team and following the predefined procedures and protocols to respond to the breach. Invoking the incident response plan helps to coordinate the communication and collaboration with the third-party provider, assess the scope and impact of the breach, contain and eradicate the threat, recover the affected systems and data, and report and disclose the incident to the relevant stakeholders and authorities.

The information security framework is a set of principles, standards, guidelines, and best practices that define the scope, objectives, and requirements for information security in an organization. The information security framework is most helpful when creating information security policies because it provides a consistent and coherent approach to managing information security risks, aligning with business goals and strategy, and complying with relevant laws and regulations. The information security framework also helps to establish the roles, responsibilities, and accountability of all stakeholders involved in information security governance, management, and operations.

 The online bank should first isolate the affected network segment, as this is the most effective way to contain the attack and prevent it from spreading to other parts of the network or compromising more data or systems. Isolating the affected network segment also helps to preserve the evidence and facilitate the investigation and recovery process. Reporting the root cause to the board of directors, assessing whether personally identifiable information (Pll) is compromised, and shutting down the entire network are not the first actions that the online bank should take, as they may not be feasible or appropriate at the time of the attack, and may cause more disruption, confusion, or damage to the business operations and reputation. References = CISM Review Manual 2023, page 1641; CISM Review Questions, Answers & Explanations Manual 2023, page 362; ISACA CISM - iSecPrep, page 213

Security awareness training is the most effective way to ensure information security policies are understood, as it educates employees on the purpose, content and importance of the policies, and how to comply with them. (From CISM Review Manual 15th Edition)

Intelligent middleware enables dynamic rerouting and automated load balancing, which is crucial for high availability. This minimizes downtime and ensures continuity without manual intervention.

“Middleware solutions can provide automated failover capabilities, improving system resilience and availability.”

— CISM Review Manual 15th Edition, Chapter 3: Program Development and Management, Section: Availability and Resilience*

Manual failover and cold sites introduce delays, which are not suitable for e-business environments requiring near-zero downtime.

The reduction of organizational risk is the desired outcome that best supports a decision to invest in a new security initiative. The organizational risk is the level of exposure or uncertainty that the organization faces in achieving its objectives. The organizational risk is influenced by various factors, such as the threat landscape, the vulnerability of the assets, the impact of the incidents, and the effectiveness of the controls. The information security manager should evaluate the organizational risk and propose security initiatives that can reduce the risk to an acceptable level. The security initiatives should be aligned with the business goals, the risk appetite, and the available resources of the organization. The security initiatives should also provide a positive return on investment (ROI) or value for money (VFM) for the organization. The reduction of organizational risk is the ultimate goal and benefit of any security initiative, as it enhances the security posture, performance, and resilience of the organization. Enhanced security monitoring and reporting, reduced control complexity, and enhanced threat detection capability are all possible outcomes of security initiatives, but they are not the best ones to support a decision to invest in a new security initiative. These outcomes are more specific and technical, and they may not directly relate to the business objectives or the risk appetite of the organization. These outcomes are also intermediate or enabling, rather than final or ultimate, as they may not necessarily lead to the reduction of organizational risk. For example, enhanced security monitoring and reporting may improve the visibility and awareness of the security status, but it may not prevent or mitigate the incidents. Reduced control complexity may simplify the security management and maintenance, but it may not address the emerging or evolving threats. Enhanced threat detection capability may increase the speed and accuracy of identifying the attacks, but it may not reduce the impact or the likelihood of the attacks. Therefore, the reduction of organizational risk is the best outcome to support a decision to invest in a new security initiative, as it demonstrates the value and effectiveness of the security initiative for the organization. References = CISM Review Manual 2023, page 40 1; CISM Practice Quiz 2

Influencing human behavior is the primary benefit of an information security awareness training program because it helps to reduce the human errors and vulnerabilities that can compromise the security of data and systems. An information security awareness training program is a process or a program that informs and empowers users to protect data and computing assets from security risks and cyberattacks. It includes educational offerings that cover regulatory requirements, compliance policies, and safe computing practices. An information security awareness training program helps to influence human behavior by raising awareness of the security threats and challenges, enhancing knowledge and skills of the security best practices and controls, and fostering a positive security culture and attitude among the users. By influencing human behavior, an information security awareness training program can improve the security posture and performance of the organization, as well as prevent or mitigate the impact of security incidents. Therefore, influencing human behavior is the correct answer.

= The best way to ensure that the disaster recovery plan (DRP) can be carried out in an emergency is to provide annual disaster recovery training to the appropriate staff, such as the disaster recovery team, the business process owners, and the IT staff. Disaster recovery training is a process of educating and preparing the staff for their roles, responsibilities, and actions in the event of a disaster that affects the availability, integrity, or confidentiality of the information assets and systems that support the business processes and functions. Disaster recovery training can help to ensure that the staff are aware, capable, and confident to execute the DRP, as well as to minimize the impact and damage to the business continuity, reputation, and value. Disaster recovery training can also help to evaluate the adequacy, accuracy, and applicability of the DRP, as well as to identify and address any gaps, weaknesses, or errors that could hinder or compromise the disaster recovery process. Disaster recovery training can also help to document and report the training details, activities, and outcomes, and to provide feedback and recommendations for improvement and optimization of the DRP and the training process.

Storing disaster recovery documentation in a public cloud, maintaining an outsourced contact center in another country, and requiring disaster recovery documentation be stored with all key decision makers are all possible ways to ensure the availability and accessibility of the DRP in an emergency, but they are not the best ones. Storing disaster recovery documentation in a public cloud is a process of using a third-party service provider to store and manage the DRP documents online, which can offer benefits such as scalability, flexibility, and cost-efficiency, but also risks such as data breach, data loss, or service disruption. Maintaining an outsourced contact center in another country is a process of using a third-party service provider to handle the communication and coordination of the disaster recovery process with the internal and external stakeholders, such as the customers, partners, or regulators, which can offer benefits such as redundancy, reliability, and expertise, but also risks such as cultural, legal, or contractual issues. Requiring disaster recovery documentation be stored with all key decision makers is a process of ensuring that the senior management and the business process owners have a copy of the DRP documents, which can offer benefits such as accountability, authority, and visibility, but also risks such as inconsistency, duplication, or unauthorized access. References = CISM Review Manual 15th Edition, pages 233-2341; CISM Practice Quiz, question 1602

An organization's information security strategy should be aligned with its risk tolerance, which is the level of risk that an organization is willing to accept in pursuit of its objectives. The strategy should aim to balance the cost of security controls with the potential impact of security incidents on the organization's objectives. Therefore, an organization's risk tolerance has the greatest influence on its information security strategy.

The organization’s risk tolerance has the greatest influence on its information security strategy because it determines how much risk the organization is willing to accept and how much resources it will allocate to mitigate or transfer risk. The organizational structure, industry security standards, and information security awareness are important factors that affect the implementation and effectiveness of an information security strategy but not as much as the organization’s risk tolerance.

An information security strategy is a high-level plan that defines how an organization will achieve its information security objectives and address its information security risks. An information security strategy should align with the organization’s business strategy and reflect its mission, vision, values, and culture. An information security strategy should also consider the external and internal factors that influence the organization’s information security environment such as laws, regulations, competitors, customers, suppliers, partners, stakeholders, employees etc.

The best way to ensure that frequently encountered incidents are reflected in the user security awareness training program is to include examples of help desk requests. Help desk requests are requests for assistance or support from users who encounter problems or issues related to information security, such as password resets, malware infections, phishing emails, unauthorized access, data loss, or system errors. Help desk requests can provide valuable insights into the types, frequencies, and impacts of the incidents that affect the users, as well as the users’ knowledge, skills, and behaviors regarding information security. By including examples of help desk requests in the user security awareness training program, the information security manager can achieve the following benefits12:

Increase the relevance and effectiveness of the training content: By using real-life scenarios and cases that the users have experienced or witnessed, the information security manager can make the training content more relevant, engaging, and applicable to the users’ needs and situations. The information security manager can also use the examples of help desk requests to illustrate the consequences and costs of the incidents, and to highlight the best practices and solutions to prevent or resolve them. This can help the users to understand the importance and value of information security, and to improve their knowledge, skills, and attitudes accordingly.

Identify and address the gaps and weaknesses in the training program: By analyzing the patterns and trends of the help desk requests, the information security manager can identify and address the gaps and weaknesses in the existing training program, such as outdated or inaccurate information, insufficient or ineffective coverage of topics, or lack of feedback or evaluation. The information security manager can also use the examples of help desk requests to measure and monitor the impact and outcomes of the training program, such as changes in the number, type, or severity of the incidents, or changes in the users’ satisfaction, performance, or behavior.

Enhance the communication and collaboration with the users and the help desk staff: By including examples of help desk requests in the user security awareness training program, the information security manager can enhance the communication and collaboration with the users and the help desk staff, who are the key stakeholders and partners in information security. The information security manager can use the examples of help desk requests to solicit feedback, suggestions, or questions from the users and the help desk staff, and to provide them with timely and relevant information, guidance, or support. The information security manager can also use the examples of help desk requests to recognize and appreciate the efforts and contributions of the users and the help desk staff in reporting, responding, or resolving the incidents, and to encourage and motivate them to continue their involvement and participation in information security.

The other options are not the best way to ensure that frequently encountered incidents are reflected in the user security awareness training program, as they are less reliable, relevant, or effective sources of information. Results of exit interviews are feedback from employees who are leaving the organization, and they may not reflect the current or future incidents that the remaining or new employees may face. Previous training sessions are records of the past training activities, and they may not capture the changes or updates in the information security environment, threats, or requirements. Responses to security questionnaires are answers to predefined questions or surveys, and they may not cover all the possible or emerging incidents that the users may encounter or experience12. References = Information Security Awareness Training: Best Practices - Infosec Resources, How to Create an Effective Security Awareness Training Program - Infosec Resources, Security Awareness Training: How to Build a Successful Program - ISACA, Security Awareness Training: How to Educate Your Employees - ISACA
