Explanation
Senior management that is part of the security steering committee is in the best position to approve plans to implement an information security governance framework. An internal auditor is secondary' to the authority and influence of senior management. Information security management should not have the authority to approve the security governance framework. Infrastructure management will not be in the best position since it focuses more on the technologies than on the business.

Explanation
Security metrics are the most important to include in a report to key stakeholders regarding the effectiveness of an information security program because they provide objective and measurable evidence of security performance and progress. Security metrics can include measures such as the number and severity of security incidents, the level of compliance with security policies and standards, the effectiveness of security controls, and the return on investment (ROI) of security initiatives. The other choices may also be included in a security report, but security metrics are the most important.
An information security program is a set of policies, procedures, standards, guidelines, and tools that aim to protect an organization's information assets from threats and ensure compliance with laws and regulations.
The effectiveness of an information security program depends on various factors, such as the organization's risk appetite, business objectives, resources, culture, and external environment. Regular reporting to key stakeholders, such as senior management, the board of directors, and business partners, is critical to maintaining their support and buy-in for the program. The report should provide clear and concise information on the program's status, achievements, challenges, and future plans, and it should be tailored to the audience's needs and expectations.

Network segmentation reduces the impact of traffic sniffing by limiting the amount of traffic that may be visible on any one network segment. Network segmentation would not mitigate the risk posed by denial of service (DoS) attacks, virus infections or IP address spoofing since each of these would be able to traverse network segments.
