The development phase is the stage of the system development life cycle (SDLC) where the system requirements, design, architecture, and implementation are performed. The development phase is most challenging to implement security controls because it involves complex and dynamic processes that may not be well understood or documented. Security controls are essential for ensuring the confidentiality, integrity, and availability of the system and its data, as well as for complying with regulatory and contractual obligations. However, security controls may also introduce additional costs, risks, and constraints to the development process, such as:

Increased complexity and overhead of testing, verification, validation, and maintenance

Reduced flexibility and agility of changing requirements or design

Increased dependency on external vendors or third parties for security services or products

Increased vulnerability to errors, defects, or vulnerabilities in the code or configuration

Increased difficulty in measuring and reporting on security performance or effectiveness

Therefore, implementing security controls in the development phase requires careful planning, coordination, communication, and collaboration among all stakeholders involved in the SDLC. It also requires a clear understanding of the security objectives, scope, criteria, standards, policies, procedures, roles, responsibilities, and resources for the system. Moreover, it requires a proactive approach to identifying and mitigating potential threats or risks that may affect the security of the system.

= When briefing executives about the current state of the information security program, the most important consideration is to use appropriate language for the target audience. This means avoiding technical jargon, acronyms, and details that may confuse or bore the executives, and instead focusing on the business value, risks, and benefits of the information security program. The other options are not as important or relevant as using appropriate language, although they may also be useful to include in the briefing. For example, a situational forecast may be helpful to show the future trends and challenges, but it is not as essential as communicating the current state clearly and concisely. Similarly, trend charts for metrics and a rating system to demonstrate program effectiveness may be useful to support the briefing, but they are not as critical as using language that the executives can understand and relate to.Reference=

= According to the CISM Manual1, risk is defined as the combination of the probability of an event and its consequence. Therefore, determining the risk for a particular threat/vulnerability pair before controls are applied can be expressed as a function of the likelihood and impact, should a threat exploit a vulnerability. Likelihood is the probability or frequency of a threat occurring, while impact is the magnitude or severity of the harm or loss that would result from a threat exploiting a vulnerability. The higher the likelihood and impact, the higher the risk. The lower the likelihood and impact, the lower the risk.

The other options are not correct because they do not capture the full expression of risk. Option B only considers the impact, but not the likelihood, of a threat exploiting a vulnerability. Option C confuses the risk with the risk response, which is the action taken to reduce or mitigate the risk. Option D only considers the likelihood, but not the impact, of a threat attempting to exploit a vulnerability.

Baseline controls are the minimum set of security requirements that apply to all information systems in an organization, regardless of their specific functions or characteristics. They are derived from the organization's security policies, standards, and best practices, and they reflect the organization's risk appetite and tolerance. Baseline controls provide a consistent and comprehensive foundation for the security of the information systems, and they can be tailored or supplemented by additional controls as needed for specific systems or situations. The other options are not as comprehensive as baseline controls, as they may only address certain aspects or aspects of the security requirements, or they may vary depending on the system or the context. For example, risk assessment results are an important input for defining the security requirements, but they are not the requirements themselves. Audit findings are an output of evaluating the compliance and effectiveness of the security requirements, but they are not the requirements themselves. Key risk indicators (KRIs) are metrics that measure the level of risk exposure and performance of the security requirements, but they are not the requirements themselves.Reference=

Senior management support is essential to ensuring effective incident response because it provides the necessary authority, resources, and guidance for the information security team to perform their roles and responsibilities. Senior management support also helps to establish the goals, scope, policies, and procedures for the incident response plan (IRP), as well as to ensure its alignment with the business objectives and strategy. Senior management support also fosters a culture of security awareness, accountability, and collaboration among all stakeholders involved in the incident response process.

The other options are not essential to ensuring effective incident response, although they may be helpful or beneficial. A business continuity plan (BCP) is a document that outlines the actions and arrangements to ensure the continuity of critical business functions in the event of a disruption or disaster. A cost-benefit analysis is a method of comparing the costs and benefits of different alternatives or solutions to a problem. A classification scheme is a system of categorizing information assets based on their sensitivity, value, and criticality.

This approach is the best because it ensures that users have the minimum level of access required to perform their job functions, which reduces the risk of unauthorized access or misuse of data. User roles are defined based on the business needs and responsibilities of the users, and they can be easily managed and audited.

answer : ''Defining access privileges based on user roles is the best approach because it allows the data owner to assign the minimum level of access required for each role and to review and update the roles periodically'' (p. 23).

This outcome indicates that the employees are more aware of the signs and techniques of social engineering and are able to report them to the appropriate authorities. This also helps to prevent successful attacks and reduce the impact of potential breaches.

Procedures are the detailed steps or instructions for performing specific tasks or activities. They are usually aligned with standards, policies and guidelines, but they are more specific and prescriptive. System maintenance instructions and schedules are examples of procedures that should be documented and followed to ensure the proper functioning and security of the system.

Performing post-incident reviews is the best way to enhance training for incident response teams because it allows them to identify the strengths and weaknesses of their response, learn from the lessons and best practices, and implement corrective actions and improvement plans for future incidents. Post-incident reviews also help to evaluate the effectiveness and efficiency of the incident response process and procedures, and to update them as needed.
