A gap analysis is a process of comparing the current state of an organization's security posture with the desired or required state, and identifying the gaps or discrepancies that need to be addressed. A gap analysis helps to determine the current level of compliance with relevant regulations, standards, and best practices, and to prioritize the actions and resources needed to achieve the desired level of compliance1. A gap analysis should be performed first when developing a security strategy in support of a new service that is subject to regulations, because it provides the following benefits2:
* It helps to understand the scope and impact of the new service on the organization's security objectives, risks, and controls.
* It helps to identify the legal, regulatory, and contractual requirements that apply to the new service, and the potential penalties or consequences of non-compliance.
* It helps to assess the effectiveness and efficiency of the existing security controls, and to identify the gaps or weaknesses that need to be remediated or enhanced.
* It helps to align the security strategy with the business goals and objectives of the new service, and to ensure the security strategy is consistent and coherent across the organization.
* It helps to communicate the security requirements and expectations to the stakeholders involved in the new service, and to obtain their support and commitment.
The other options, such as determining security controls for the new service, establishing a compliance program, or hiring new resources to support the service, are not the first steps when developing a security strategy in support of a new service that is subject to regulations, because they depend on the results and recommendations of the gap analysis. Determining security controls for the new service requires a clear understanding of the security requirements and risks associated with the new service, which can be obtained from the gap analysis. Establishing a compliance program requires a systematic and structured approach to implement, monitor, and improve the security controls and processes that ensure compliance, which can be based on the gap analysis. Hiring new resources to support the service requires a realistic and justified estimation of the human and financial resources needed to achieve the security objectives and compliance, which can be derived from the gap analysis.

A key consideration in the use of quantitative risk analysis is that it assigns numeric values to exposures of information assets, such as the probability of occurrence, the frequency of occurrence, the impact of occurrence, and the monetary value of the assets. These numeric values help to measure and compare the risks in a more objective and consistent way, and to support the decision-making process based on cost-benefit analysis. Quantitative risk analysis also requires reliable and accurate data sources, and it may involve the use of statistical tools and techniques.

The underlying reason for the user error is the most important factor to determine during the post-incident review, as this helps the information security manager to understand the root cause of the breach, and to implement corrective and preventive actions to avoid similar incidents in the future. The underlying reason for the user error may be related to the lack of training, awareness, guidance, or motivation of the user, or to the complexity, usability, or design of the system or process that the user was using. By identifying the underlying reason for the user error, the information security manager can address the human factor of the information security program, and improve the security culture and behavior of the organization. The time and location that the breach occurred, evidence of previous incidents caused by the user, and appropriate disciplinary procedures for user error are not the most important factors to determine during the post-incident review, as they do not provide a comprehensive and holistic understanding of the breach, and may not help to prevent or reduce the likelihood or impact of future incidents.

= The best way to enable the integration of information security governance into corporate governance is to establish an information security steering committee with business representation. An information security steering committee is a group of senior executives and managers from different business units and functions who are responsible for overseeing, directing, and supporting the information security program and strategy of the organization. An information security steering committee with business representation can enable the integration of information security governance into corporate governance by providing the following benefits12:
Align the information security objectives and priorities with the business objectives and priorities, and ensure that the information security program and strategy support and enable the achievement of the organizational goals and performance.
Communicate and promote the value and importance of information security to the board of directors, senior management, and other stakeholders, and ensure that information security is considered and incorporated in the decision making and planning processes of the organization.
Provide guidance and direction to the information security manager and the information security team, and ensure that they have the necessary authority, resources, and support to implement and maintain the information security program and strategy effectively and efficiently.
Monitor and evaluate the performance and outcomes of the information security program and strategy, and ensure that they are aligned with the expectations and requirements of the organization and its stakeholders, as well as the relevant laws, regulations, standards, and best practices.
Identify and address the issues, challenges, and opportunities related to information security, and ensure that the information security program and strategy are continuously improved and updated to reflect the changes and developments in the internal and external environment.
The other options are not the best way to enable the integration of information security governance into corporate governance, as they are less comprehensive, effective, or influential than establishing an information security steering committee with business representation. Well-documented information security policies and standards are important components of the information security program and strategy, but they are not sufficient to enable the integration of information security governance into corporate governance, as they may not reflect or align with the business needs, priorities, or expectations, and they may not be communicated, implemented, or enforced properly or consistently across the organization. Clear lines of authority across the organization are important factors for the information security governance structure, but they are not sufficient to enable the integration of information security governance into corporate governance, as they may not ensure the involvement, participation, or support of the senior executives, managers, and other stakeholders who are responsible for or affected by information security. Senior management approval of the information security strategy is an important outcome of the information security governance process, but it is not sufficient to enable the integration of information security governance into corporate governance, as it may not ensure the alignment, communication, or monitoring of the information security strategy with the business strategy, and it may not ensure the accountability, responsibility, or authority of the information security manager and the information security team12.

= Penetration testing is most appropriate when a new system is about to go live, because it is a method of evaluating the security of a system by simulating an attack from a malicious source. Penetration testing can help to identify and exploit vulnerabilities, assess the impact and risk of a breach, and provide recommendations for remediation and improvement. Penetration testing can also help to validate the effectiveness of the security controls and policies implemented for the new system, and ensure compliance with relevant standards and regulations. Penetration testing is usually performed after the system has undergone other types of testing, such as functional, performance, and usability testing, and before the system is deployed to the production environment. Penetration testing is not as appropriate when a new system is being designed, because the system is still in the early stages of development and may not have all the features and functionalities implemented. Penetration testing at this stage may not provide a realistic or comprehensive assessment of the system's security, and may cause delays or disruptions in the development process. Penetration testing is also not as appropriate when a security policy is being developed, because the policy is a high-level document that defines the goals, objectives, and principles of information security for the organization. Penetration testing is a technical and operational activity that tests the implementation and enforcement of the policy, not the policy itself. Penetration testing is also not as appropriate when a security incident has occurred, because the incident may have already compromised the system and caused damage or loss. Penetration testing at this stage may not be able to prevent or mitigate the incident, and may interfere with the incident response and recovery efforts. Penetration testing after an incident may be useful for forensic analysis and lessons learned, but it is not the primary or immediate response to an incident.
