An email digital signature will verify to recipient the integrity of an email message because it ensures that the message has not been altered or tampered with during transit, and confirms that the message originated from the sender and not an imposter. An email digital signature will not protect the confidentiality of an email message because it does not encrypt or hide the message content from unauthorized parties. An email digital signature will not automatically correct unauthorized modification of an email message because it does not change or restore the message content if it has been altered or tampered with. An email digital signature will not prevent unauthorized modification of an email message because it does not block or stop any attempts to alter or tamper with the message content.

Comprehensive and Detailed Step-by-Step Explanation:

Determining downtime costs requires understanding the financial and operational impact on the business.

A. Fault tree analysis: Primarily used for identifying the root causes of failures, not for assessing downtime costs.

B. Cost-benefit analysis: Compares the costs and benefits of implementing controls but does not specifically address downtime.

C. Return on investment (ROI) analysis: Evaluates the financial return of an investment rather than the cost of an outage.

D. Business impact analysis (BIA): This is the BEST answer because a BIA identifies the effects of a disruption on critical business functions and quantifies the financial impact, including downtime costs.

The correct answer is B because integrating information security governance into corporate governance ensures that security decisions are made as part of overall business direction, risk management, investment, and accountability. Security strategy should not operate separately from enterprise strategy. When information security governance is embedded in corporate governance, security objectives are aligned with business objectives, risk appetite, regulatory obligations, and stakeholder expectations. Establishing business KPIs may help measure business performance, but it does not directly align security strategy. Conformance to industry standards can improve maturity and consistency, but standards may not fully reflect the organization’s unique business priorities. Reporting security risk in metrics is useful, but reporting alone does not create strategic alignment. CISM emphasizes that information security must support enterprise objectives and be governed through appropriate structures, roles, and oversight. Therefore, integrating information security governance into corporate governance is the best way to align security and business strategies.

The next step for the information security manager should be to inventory and review the current security policies to understand the existing security requirements, controls, and gaps. This will help to identify the areas that need to be updated, revised, or replaced to align with the current business needs and objectives, as well as the legal and regulatory requirements. Updating the policies in accordance with the best business practices, performing a risk assessment of the current IT environment, or gaining an understanding of the current business direction are important activities, but they should be done after reviewing the current security policies.

Residual risk is the risk that remains after implementing risk mitigation actions. It is the most valuable component for senior management because it helps them to evaluate the effectiveness and efficiency of risk management and make informed decisions about risk acceptance, transfer or avoidance. References = CISM Review Manual, 16th Edition, Chapter 2, Section 2.3.41

 The organization’s vision and mission should be the PRIMARY basis for an information security strategy, as they define the purpose and direction of the organization and its information security needs. A comprehensive gap analysis is a tool to identify the current state and desired state of information security, and the actions needed to close the gap. Information security policies are the high-level statements of management’s intent and expectations for information security, and are derived from the information security strategy. Audit and regulatory requirements are external factors that influence the information security strategy, but are not the primary basis for it. References = CISM Review Manual, 16th Edition, pages 17-181; CISM Review Questions, Answers & Explanations Manual, 10th Edition, page 782

The primary basis for an information security strategy should be the organization ' s vision and mission. The organization ' s vision and mission should be the foundation for the security strategy, and should inform and guide the security policies, procedures, and practices that are implemented. The results of a comprehensive gap analysis, information security policies, and audit and regulatory requirements should all be taken into consideration when developing the security strategy, but should not be the primary basis.
