Isaca CISM Based on Real Exam Environment

 The CEO is the best able to influence the security culture within an organization because the CEO sets the tone and direction for the organization and has the authority and responsibility to ensure that the organization’s objectives are aligned with its strategy. The CEO can also communicate the importance and value of information security to all stakeholders and foster a culture of security awareness and accountability. The CISO, CIO and COO are important roles in information security management, but they do not have the same level of influence and authority as the CEO. References = CISM Review Manual, 16th Edition, page 221; CISM Exam Content Outline, Domain 1, Task 12

The Chief Information Security Officer (CISO) is responsible for leading and coordinating an organization's information security program, and as such, is in a prime position to influence the security culture within the organization. The CISO is responsible for setting policies and standards, educating employees about security risks and best practices, and ensuring that the organization is taking appropriate measures to mitigate security risks. By demonstrating a strong commitment to information security, the CISO can help to create a security-aware culture within the organization.

= Security reporting is the process of providing relevant and timely information on the status and performance of the information security program to the stakeholders. Security reporting should be aligned with the business objectives and risk appetite of the organization, and should provide meaningful insights and recommendations for decision making and improvement. Security reporting should also include forward-looking trends, which are projections or predictions of future events or conditions based on historical data, current situation, and external factors. Forward-looking trends can help the organization anticipate and prepare for potential risks and opportunities, and adjust their strategies and plans accordingly.

One of the most effective ways to communicate forward-looking trends within security reporting is to use key risk indicators (KRIs). KRIs are metrics that measure the level of exposure or likelihood of a risk event occurring, and provide early warning signals of potential changes in the risk profile. KRIs can help the organization monitor and manage the key risks that may affect the achievement of their objectives, and take proactive actions to mitigate or avoid them. KRIs can also help the organization identify emerging risks and trends, and evaluate the effectiveness of their risk treatment options. KRIs should be aligned with the risk appetite and tolerance of the organization, and should be regularly reviewed and updated to reflect the changing risk environment.

The other options are not the most effective ways to communicate forward-looking trends within security reporting. Key control indicators (KCIs) are metrics that measure the effectiveness and efficiency of the security controls implemented to reduce the impact or likelihood of a risk event. KCIs can help the organization assess and improve the performance of their security processes and activities, and ensure compliance with the security policies and standards. However, KCIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. Key performance indicators (KPIs) are metrics that measure the achievement of the security objectives and goals, and demonstrate the value and contribution of the information security program to the organization. KPIs can help the organization evaluate and communicate the results and outcomes of their security initiatives and projects, and align them with the business strategy and vision. However, KPIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. Key goal indicators (KGIs) are metrics that measure the progress and completion of the security goals and targets, and indicate the degree of success and satisfaction of the information security program. KGIs can help the organization track and report the status and milestones of their security plans and actions, and ensure alignment with the stakeholder expectations and requirements. However, KGIs do not directly measure the level of exposure or likelihood of a risk event, and may not provide sufficient information on the future trends and scenarios. References = CISM Review Manual, 16th Edition, ISACA, 2020, pp. 77-78, 81-821; CISM Online Review Course, Domain 3: Information Security Program Development and Management, Module 4: Information Security Program Resources, ISACA2

Reverse lookups can be used to prevent successful IP spoofing. IP spoofing is a type of attack in which an attacker sends packets with a false source IP address in order to disguise their identity or impersonate another system. By performing reverse lookups on the source IP address of incoming packets, the system can verify that the packets are coming from a trusted source, and any packets with an invalid or spoofed source IP can be discarded. This is an important measure for preventing IP spoofing, and can help to reduce the risk of other types of attacks, such as DoS attacks, session hacking, and phishing attacks.

The first step when a new vulnerability is identified is to re-evaluate the risk associated with the vulnerability. This may require an update to the risk assessment and the implementation of additional controls. Informing senior management of the vulnerability is important, but should not be the first step. Implementing compensating controls may also be necessary, but again, should not be the first step. Asking the business owner for a remediation plan may be useful, but only after the risk has been re-evaluated.

The information security manager should first re-evaluate the risk posed by the new vulnerability to determine its impact and likelihood. Based on this assessment, appropriate actions can be taken such as informing senior management, implementing compensating controls, or requesting a remediation plan from the business owner. The other choices are possible actions but not necessarily the first one.

A vulnerability is a weakness that can be exploited by an attacker to compromise a system or network2. A vulnerability can affect key data processing systems within an organization if it exposes sensitive information, disrupts business operations, or damages assets2. A vulnerability assessment is a process of identifying and evaluating vulnerabilities and their potential consequences2
