Comprehensive and Detailed Explanation: Employee accountability is the degree to which employees are responsible for their actions and outcomes related to information security. It reflects the extent to which employees understand their roles and responsibilities, follow the policies and procedures, report incidents and breaches, and comply with legal and regulatory requirements. Embedding security responsibilities into job descriptions helps to clarify the expectations and obligations of employees, as well as the consequences of non-compliance or negligence. It also helps to align the security objectives with the business goals and strategies, and to foster a culture of security awareness and responsibility.

Senior leadership needs to understand how Zero Trust supports risk reduction and business needs. Communicating the impact on risk reduction and user experience aligns security initiatives with business goals.

“Communicating how security initiatives support business objectives and risk reduction is critical for gaining senior management support.”

 A security policy is a formal statement of the rules and principles that govern the protection of information assets in an organization. A security policy defines the scope, objectives, roles and responsibilities, and standards of the information security program. A primary purpose of creating security policies is to implement management’s security governance strategy, which is the framework that guides the direction and alignment of information security with the business goals and objectives. A security policy translates the management’s vision and expectations into specific and measurable requirements and controls that can be implemented and enforced by the information security staff and other stakeholders. A security policy also helps to establish the accountability and authority of the information security function and to demonstrate the commitment and support of the senior management for the information security program.

Entering identified risks into the organization's risk register ensures that they are documented, tracked, assigned, and addressed. Without recording in the risk register, there’s no formal mechanism to manage, treat, or monitor the risk.

“The risk register is the central repository for tracking all known risks, their status, and treatment plans.”

— CISM Review Manual 15th Edition, Chapter 2: Information Risk Management, Section: Risk Response and Risk Register*

Confidentiality is the security objective that best ensures that information is protected against unauthorized disclosure. Confidentiality means that only authorized parties can access or view sensitive or classified information. Integrity means that information is accurate and consistent and has not been tampered with or modified by unauthorized parties. Authenticity means that information is genuine and trustworthy and has not been forged or misrepresented by unauthorized parties. Nonrepudiation means that information can be verified and proven to be sent or received by a specific party without any possibility of denial.

Following the escalation process ensures that the incident is managed in accordance with established protocols, involving the right stakeholders and prioritizing the incident appropriately.

“Following the escalation process is critical to ensure that incidents are handled appropriately and that the right personnel are engaged at the right time.”

— CISM Review Manual 15th Edition, Chapter 4: Incident Management, Section: Escalation Procedures*

ISACA practice questions highlight that proper escalation is vital to ensure incidents are managed effectively and consistently.

Ignored alert messages could have been prevented by conducting regular incident response testing because it would have ensured that the help desk staff are familiar with and trained on how to handle different types of alert messages from different sources, and how to escalate them appropriately. The server being compromised could not have been prevented by conducting regular incident response testing because it is related to security vulnerabilities or weaknesses in the server configuration or authentication mechanisms. The brute force attack could not have been prevented by conducting regular incident response testing because it is related to security threats or attacks from external sources. Stolen data could not have been prevented by conducting regular incident response testing because it is related to security breaches or incidents that may occur despite the incident response plan or process.

 The primary basis for determining the value of assets should be the business cost when assets are not available. This is because the value of assets is not only determined by their acquisition or replacement cost, but also by their contribution to the organization’s business objectives and processes. The business cost when assets are not available reflects the potential impact of losing or compromising the assets on the organization’s operations, performance, reputation, and compliance. The business cost when assets are not available can be estimated by conducting a business impact analysis (BIA), which identifies the criticality, dependencies, and recovery requirements of the assets. By using the business cost when assets are not available as the primary basis for determining the value of assets, the organization can prioritize the protection and management of the assets according to their importance and risk level. References = CISM Review Manual 15th Edition, page 64, page 65.

Enforcing technical security standards is the most effective way to ensure that a new server is appropriately secured because it ensures that the server complies with the organization’s security policies and best practices, such as encryption, authentication, patching, and hardening. Performing secure code reviews is not relevant for securing a new server, unless it is running custom applications that need to be verified for security flaws. Conducting penetration testing is not sufficient for securing a new server, because it only identifies vulnerabilities that can be exploited by attackers, but does not fix them. Initiating security scanning is not sufficient for securing a new server, because it only detects known vulnerabilities or misconfigurations, but does not enforce security standards or remediate issues.

The answer to the question is C. Risk response scenarios. This is because risk response scenarios are the predefined plans and actions that the organization will take to respond to specific types of incidents, such as cyberattacks, natural disasters, or data breaches. Risk response scenarios should be aligned with the corporate strategy, which defines the vision, mission, goals, and objectives of the organization, and guides the decision-making and resource allocation processes. By aligning the risk response scenarios with the corporate strategy, the organization can ensure that the incident response plan supports the achievement of the desired outcomes and benefits, and minimizes the impact and disruption to the business operations and performance.

Misconfigured alert thresholds can lead to either false positives (alert fatigue) or missed critical events, undermining the purpose of the SIEM.

“SIEM effectiveness relies on appropriate configuration. Poor threshold settings can result in either overwhelming alerts or failure to detect real threats.”

— CISM Review Manual 15th Edition, Chapter 4: Incident Management, Section: Security Monitoring Tools*

The control owner is the individual accountable for implementing and managing specific controls that mitigate risks. While the risk owner is responsible for the overall risk and decision-making, it is the control owner who ensures the selected mitigation is effectively implemented and maintained.

“The control owner is responsible for ensuring that the control is properly designed, implemented, and operating effectively.”

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

ISACA practice questions stress this distinction: the control owner is tasked with the execution of mitigation strategies.

The information security manager’s best course of action is to report the findings of the risk assessment to the key stakeholders, such as senior management, business owners, and regulators. This will ensure that the stakeholders are aware of the potential impact of the risk and can make informed decisions on how to address it. The other options are possible actions to take after reporting the findings, but they are not the best course of action in this scenario.

The most important thing to include in the vendor selection criteria when procuring security services from a third-party vendor is B. Alignment of the vendor’s business objectives with enterprise security goals. This is because the vendor should be able to understand and support the enterprise’s security vision, mission, strategy, and policies, and provide services that are consistent and compatible with them. The vendor should also be able to demonstrate how their services add value, reduce risk, and enhance the performance and maturity of the enterprise’s information security program. The alignment of the vendor’s business objectives with enterprise security goals can help to ensure a successful and long-term partnership, and avoid any conflicts, gaps, or issues that may arise from misalignment or divergence.

= The information security manager’s first course of action in this situation should be to conduct a risk assessment, which is a process of identifying, analyzing, and evaluating the information security risks that arise from the violation of the policy prohibiting the use of cameras at the office. The risk assessment can help to determine the likelihood and impact of the unauthorized or inappropriate use of the cameras on the smartphones and tablet computers, such as capturing, transmitting, or disclosing sensitive or confidential information, compromising the privacy or security of the employees, customers, or partners, or violating the legal or regulatory requirements. The risk assessment can also help to identify and prioritize the appropriate risk treatment options, such as implementing technical, administrative, or physical controls to disable, restrict, or monitor the camera usage, enforcing the policy compliance and awareness, or revising the policy to reflect the current business needs and environment. The risk assessment can also help to communicate and report the risk level and status to the senior management and the relevant stakeholders, and to provide feedback and recommendations for improvement and optimization of the policy and the risk management process.

Revising the policy, performing a root cause analysis, and communicating the acceptable use policy are all possible courses of action that the information security manager can take after conducting the risk assessment, but they are not the first ones. Revising the policy is a process of updating and modifying the policy to align with the business objectives and strategy, to address the changes and challenges in the business and threat environment, and to incorporate the feedback and suggestions from the risk assessment and the stakeholders. Performing a root cause analysis is a process of investigating and identifying the underlying causes and factors that led to the violation of the policy, such as the lack of awareness, training, or enforcement, the inconsistency or ambiguity of the policy, or the conflict or gap between the policy and the business requirements or expectations. Communicating the acceptable use policy is a process of informing and educating the employees and the other users of the smartphones and tablet computers about the purpose, scope, and content of the policy, the roles and responsibilities of the users, the benefits and consequences of complying or violating the policy, and the methods and channels of reporting or resolving any policy issues or incidents. References = CISM Review Manual 15th Edition, pages 51-531; CISM Practice Quiz, question 1482

 Alignment between corporate and information security governance means that the information security program supports the organizational goals and objectives, and is integrated into the enterprise governance structure. The best evidence of alignment is the senior management sponsorship, which demonstrates the commitment and support of the top-level executives and board members for the information security program. Senior management sponsorship also ensures that the information security program has adequate resources, authority, and accountability to achieve its objectives and address the risks and issues that affect the organization. Senior management sponsorship also helps to establish a culture of security awareness and compliance throughout the organization, and to communicate the value and benefits of the information security program to the stakeholders.

Isolating affected systems limits the damage and prevents the incident from impacting other parts of the organization.

“During containment, the primary objective is to isolate affected systems to prevent further damage.”
