Scenario 5: Operaze is a small software development company that develops applications for various companies around the world. Recently, the company conducted a risk assessment to assess the information security risks that could arise from operating in a digital landscape. Using different testing methods, including penetration Resting and code review, the company identified some issues in its ICT systems, including improper user permissions, misconfigured security settings, and insecure network configurations. To resolve these issues and enhance information security, Operaze decided to implement an information security management system (ISMS) based on ISO/IEC 27001.
Considering that Operaze is a small company, the entire IT team was involved in the ISMS implementation project. Initially, the company analyzed the business requirements and the internal and external environment, identified its key processes and activities, and identified and analyzed the interested parties In addition, the top management of Operaze decided to Include most of the company's departments within the ISMS scope.
The defined scope included the organizational and physical boundaries. The IT team drafted an information security policy and communicated it to all relevant interested parties In addition, other specific policies were developed to elaborate on security issues and the roles and responsibilities were assigned to all interested parties.
Following that, the HR manager claimed that the paperwork created by ISMS does not justify its value and the implementation of the ISMS should be canceled However, the top management determined that this claim was invalid and organized an awareness session to explain the benefits of the ISMS to all interested parties.
Operaze decided to migrate Its physical servers to their virtual servers on third-party infrastructure. The new cloud computing solution brought additional changes to the company Operaze's top management, on the other hand, aimed to not only implement an effective ISMS but also ensure the smooth running of the ISMS operations. In this situation, Operaze's top management concluded that the services of external experts were required to implement their information security strategies. The IT team, on the other hand, decided to initiate a change in the ISMS scope and implemented the required modifications to the processes of the company.
What is the next step that Operaze's ISMS implementation team should take after drafting the information security policy? Refer to scenario 5.

• A. Implement the information security policy
• B. Communicate the information security policy to all employees
• C. Obtain top management's approval for the information security policy

正解：C

解説：
According to ISO/IEC 27001 : 2022 Lead Implementer, the information security policy is a high-level document that defines the organization's objectives, principles, and commitments regarding information security. The policy should be aligned with the organization's strategic direction and context, and should provide a framework for setting information security objectives and establishing the ISMS. The policy should also be approved by top management, who are ultimately responsible for the ISMS and its performance.
Therefore, after drafting the information security policy, the next step that Operaze's ISMS implementation team should take is to obtain top management's approval for the policy. This will ensure that the policy is consistent with the organization's vision and values, and that it has the necessary support and resources for its implementation and maintenance.

Based on scenario 5. in which category of the interested parties does the MR manager of Operaze belong?

• A. Both A and B
• B. Negatively influenced interested parties, because the HR Department will deal with more documentation
• C. Positively influenced interested parties, because the ISMS will increase the effectiveness and efficiency of the HR Department

正解：B

解説：
According to ISO/IEC 27001, interested parties are those who can affect, be affected by, or perceive themselves to be affected by the organization's information security activities, products, or services.
Interested parties can be classified into four categories based on their influence and interest in the ISMS:
* Positively influenced interested parties: those who benefit from the ISMS and support its implementation and operation
* Negatively influenced interested parties: those who are adversely affected by the ISMS and oppose its implementation and operation
* High-interest interested parties: those who have a strong interest in the ISMS and its outcomes, regardless of their influence
* Low-interest interested parties: those who have a weak interest in the ISMS and its outcomes, regardless of their influence In scenario 5, the HR manager of Operaze belongs to the category of negatively influenced interested parties, because he/she perceives that the ISMS will create more paperwork and documentation for the HR Department, and therefore opposes its implementation and operation. The HR manager does not benefit from the ISMS and does not support its objectives and requirements.

Scenario 2: Beauty is a cosmetics company that has recently switched to an e-commerce model, leaving the traditional retail. The top management has decided to build their own custom platform in-house and outsource the payment process to an external provider operating online payments systems that support online money transfers.
Due to this transformation of the business model, a number of security controls were implemented based on the identified threats and vulnerabilities associated to critical assets. To protect customers' information.
Beauty's employees had to sign a confidentiality agreement. In addition, the company reviewed all user access rights so that only authorized personnel can have access to sensitive files and drafted a new segregation of duties chart.
However, the transition was difficult for the IT team, who had to deal with a security incident not long after transitioning to the e commerce model. After investigating the incident, the team concluded that due to the out- of-date anti-malware software, an attacker gamed access to their files and exposed customers' information, including their names and home addresses.
The IT team decided to stop using the old anti-malware software and install a new one which would automatically remove malicious code in case of similar incidents. The new software was installed in every workstation within the company. After installing the new software, the team updated it with the latest malware definitions and enabled the automatic update feature to keep it up to date at all times. Additionally, they established an authentication process that requires a user identification and password when accessing sensitive information.
In addition, Beauty conducted a number of information security awareness sessions for the IT team and other employees that have access to confidential information in order to raise awareness on the importance of system and network security.
Which statement below suggests that Beauty has implemented a managerial control that helps avoid the occurrence of incidents? Refer to scenario 2.

• A. Beauty conducted a number of information security awareness sessions for the IT team and other employees that have access to confidential information
• B. Beauty updated the segregation of duties chart
• C. Beauty's employees signed a confidentiality agreement

正解：A

解説：
Managerial controls are administrative actions that are designed to prevent or reduce the likelihood of security incidents by influencing human behavior. They include policies, procedures, guidelines, standards, training, and awareness programs. In scenario 2, Beauty has implemented a managerial control by conducting information security awareness sessions for the IT team and other employees that have access to confidential information. These sessions aim to educate the staff on the importance of system and network security, the potential threats and vulnerabilities, and the best practices to follow to avoid the occurrence of incidents. By raising the level of awareness andknowledge of the employees, Beauty can reduce the human errors and negligence that might compromise the security of the information assets.

質問 # 28
Del&Co has decided to improve their staff-related controls to prevent incidents. Which of the following is NOT a preventive control related to the Del&Co's staff?

• A. Video cameras
• B. Control of physical access to the equipment
• C. Authentication and authorization

正解：A

解説：
According to ISO/IEC 27001:2022, Annex A.7, the objective of human resource security is to ensure that employees and contractors understand their responsibilities and are suitable for the roles for which they are considered, and to reduce the risk of human error, theft, fraud, or misuse of facilities. The standard specifies eight controls in this domain, which are:
* A.7.1 Prior to employment: This control covers the screening, terms and conditions, and roles and responsibilities of employees and contractors before they are hired.
* A.7.2 During employment: This control covers the awareness, education, and training, disciplinary process, and management responsibilities of employees and contractors during their employment.
* A.7.3 Termination and change of employment: This control covers the return of assets, removal of access rights, and exit interviews of employees and contractors when they leave or change their roles.
The other controls in Annex A are related to other aspects of information security, such as organizational, physical, and technological controls. For example:
* A.9.2 User access management: This control covers the authentication and authorization of users to access information systems and services, based on their roles and responsibilities.
* A.11.1 Secure areas: This control covers the control of physical access to the equipment and information assets, such as locks, alarms, guards, etc.
* A.13.2 Information transfer: This control covers the protection of information during its transfer, such as encryption, digital signatures, secure protocols, etc.
Therefore, video cameras are not a preventive control related to the staff, but rather a physical control related to the equipment and assets. Video cameras can be used to monitor and record the activities of the staff, but they cannot prevent them from causing incidents. They can only help to detect and investigate incidents after they occur.

質問 # 29
Which statement is an example of risk retention?

• A. An organization terminates work in the construction site during a severe storm
• B. An organization has implemented a data loss protection software
• C. An organization has decided to release the software even though some minor bugs have not been fixed yet

正解：C

解説：
According to ISO/IEC 27001 : 2022 Lead Implementer, risk retention is one of the four risk treatment options that an organization can choose to deal with unacceptable risks. Risk retention means that the organization accepts the risk without taking any action to reduce its likelihood or impact. It applies to risks that are either too costly or impractical to address, or that have a low probability or impact. Therefore, an example of risk retention is when an organization decides to release the software even though some minor bugs have not been fixed yet. This implies that the organization has assessed the risk of releasing the software with bugs and has determined that it is acceptable, either because the bugs are not critical or because the cost of fixing them would outweigh the benefits.

Which of the situations below can negatively affect the internal audit process?

• A. Reporting the internal audit results to the top management
• B. Restricting the internal auditor's access to offices and documentation
• C. Conducting internal audit interviews with all employees of the organization

正解：B

解説：
According to the ISO/IEC 27001 : 2022 Lead Implementer course, one of the factors that can negatively affect the internal audit process is the lack of cooperation from the auditees, which can manifest as restricting the internal auditor's access to offices and documentation1. This can hinder the auditor's ability to collect sufficient and appropriate audit evidence, verify the conformity of the information security management system (ISMS) with the audit criteria, and identify any nonconformities or opportunities for improvement2. Therefore, the auditees should be informed of the audit objectives,scope, criteria, and schedule in advance, and should provide the auditor with all the necessary information and resources to conduct the audit effectively3.

Scenario 7: InfoSec is a multinational corporation headquartered in Boston, MA, which provides professional electronics, gaming, and entertainment services. After facing numerous information security incidents, InfoSec has decided to establish teams and implement measures to prevent potential incidents in the future Emma, Bob. and Anna were hired as the new members of InfoSec's information security team, which consists of a security architecture team, an incident response team (IRT) and a forensics team Emma's job is to create information security plans, policies, protocols, and training to prepare InfoSec to respond to incidents effectively Emma and Bob would be full-time employees of InfoSec, whereas Anna was contracted as an external consultant.
Bob, a network expert, will deploy a screened subnet network architecture This architecture will isolate the demilitarized zone (OMZ) to which hosted public services are attached and InfoSec's publiclyaccessible resources from their private network Thus, InfoSec will be able to block potential attackers from causing unwanted events inside the company's network. Bob is also responsible for ensuring that a thorough evaluation of the nature of an unexpected event is conducted, including the details on how the event happened and what or whom it might affect.
Anna will create records of the data, reviews, analysis, and reports in order to keep evidence for the purpose of disciplinary and legal action, and use them to prevent future incidents. To do the work accordingly, she should be aware of the company's information security incident management policy beforehand Among others, this policy specifies the type of records to be created, the place where they should be kept, and the format and content that specific record types should have.
According to scenario 7, a demilitarized zone (DMZ) is deployed within InfoSec's network. What type of control has InfoSec implemented in this case?

• A. Corrective
• B. Preventive
• C. Detective

正解：B

解説：
A demilitarized zone (DMZ) is a network segment that separates the internal network from the external network, such as the Internet. It is used to host public services that need to be accessible from outside the organization, such as web servers, email servers, or DNS servers. A DMZ provides a layer of protection for the internal network by limiting the exposure of the public services and preventing unauthorized access from the external network. A DMZ is an example of a preventive control, which is a type of control that aims to prevent or deter the occurrence of an information security incident. Preventive controls reduce the likelihood of a threat exploiting a vulnerability and causing harm to the organization's information assets. Other examples of preventive controls are encryption, authentication, firewalls, antivirus software, and security awareness training.

Scenario 3: Socket Inc is a telecommunications company offering mainly wireless products and services. It uses MongoDB. a document model database that offers high availability, scalability, and flexibility.
Last month, Socket Inc. reported an information security incident. A group of hackers compromised its MongoDB database, because the database administrators did not change its default settings, leaving it without a password and publicly accessible.
Fortunately. Socket Inc. performed regular information backups in their MongoDB database, so no information was lost during the incident. In addition, a syslog server allowed Socket Inc. to centralize all logs in one server. The company found out that no persistent backdoor was placed and that the attack was not initiated from an employee inside the company by reviewing the event logs that record user faults and exceptions.
To prevent similar incidents in the future, Socket Inc. decided to use an access control system that grants access to authorized personnel only. The company also implemented a control in order to define and implement rules for the effective use of cryptography, including cryptographic key management, to protect the database from unauthorized access The implementation was based on all relevant agreements, legislation, and regulations, and the information classification scheme. To improve security and reduce the administrative efforts, network segregation using VPNs was proposed.
Lastly, Socket Inc. implemented a new system to maintain, collect, and analyze information related to information security threats, and integrate information security into project management.
Based on scenario 3, what would help Socket Inc. address similar information security incidents in the future?

• A. Using the MongoDB database with the default settings
• B. Using the access control system to ensure that only authorized personnel is granted access
• C. Using cryptographic keys to protect the database from unauthorized access

正解：C

解説：
In Scenario 3, the measure that would help Socket Inc. address similar information security incidents in the future is "B. Using cryptographic keys to protect the database from unauthorized access." Implementing cryptographic controls, including cryptographic key management, is a proactive measure to secure the data in the MongoDB database against unauthorized access. It ensures that even if attackers gain access to the database, they cannot read or misuse the data without the appropriate cryptographic keys. This approach aligns with best practices for securing sensitive data and is part of a comprehensive security strategy.

Scenario 8: SunDee is an American biopharmaceutical company, headquartered in California, the US. It specializes in developing novel human therapeutics, with a focus on cardiovascular diseases, oncology, bone health, and inflammation. The company has had an information security management system (ISMS) based on SO/IEC 27001 in place for the past two years. However, it has not monitored or measured the performance and effectiveness of its ISMS and conducted management reviews regularly Just before the recertification audit, the company decided to conduct an internal audit. It also asked most of their staff to compile the written individual reports of the past two years for their departments. This left the Production Department with less than the optimum workforce, which decreased the company's stock.
Tessa was SunDee's internal auditor. With multiple reports written by 50 different employees, the internal audit process took much longer than planned, was very inconsistent, and had no qualitative measures whatsoever Tessa concluded that SunDee must evaluate the performance of the ISMS adequately. She defined SunDee's negligence of ISMS performance evaluation as a major nonconformity, so she wrote a nonconformity report including the description of the nonconformity, the audit findings, and recommendations. Additionally, Tessa created a new plan which would enable SunDee to resolve these issues and presented it to the top management Based on scenario 8. does SunDee comply with ISO/IEC 27001 requirements regarding the monitoring and measurement process?

• A. No, because even though the standard does not imply when such a process should be performed, the company must have a monitoring and measurement process in place
• B. Yes, because the standard requires that the monitoring and measurement phase be conducted every two years
• C. Yes. because the standard does not Indicate when the monitoring and measurement phase should be performed

正解：A

解説：
According to ISO/IEC 27001:2022, clause 9.1, the organization shall determine:
* what needs to be monitored and measured, including information security processes and controls, as well as information security performance and the effectiveness of the ISMS;
* the methods for monitoring, measurement, analysis and evaluation, to ensure valid and reliable results;
* when the monitoring and measurement shall be performed;
* who shall monitor and measure;
* who shall analyze and evaluate the monitoring and measurement results; and
* how the results shall be communicated and used for decision making and improvement.
The organization shall retain documented information as evidence of the monitoring and measurement results.
The standard does not prescribe a specific frequency or method for monitoring and measurement, but it requires the organization to have a defined and documented process that is appropriate to its context, objectives, risks, and opportunities. The organization should also ensure that the monitoring and measurement results are analyzed and evaluated to determine the performance and effectiveness of the ISMS, and to identify any nonconformities, gaps, or improvement opportunities.
In the scenario, SunDee did not comply with these requirements, as it did not have a monitoring and measurement process in place, and did not monitor or measure the performance and effectiveness of its ISMS regularly. It also did not use valid and reliable methods, or communicate and use the results for improvement.
Therefore, SunDee's negligence of ISMS performance evaluation was a major nonconformity, as Tessa correctly identified.

* Integrity is the property of safeguarding the accuracy and completeness of information and processing methods. A breach of integrity occurs when information is modified or destroyed in an unauthorized or unintended manner. In this case, Diana accidently modified the order details of a customer without their permission, which resulted in the customer receiving an incorrect product. This means that the information about the customer's order was not accurate or complete, and therefore, the integrity principle was breached. Availability and confidentiality are two other information security principles, but they were not violated in this case. Availability is the property of being accessible and usable upon demand by an authorized entity, and confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems.

Scenario 4: TradeB. a commercial bank that has just entered the market, accepts deposits from its clients and offers basic financial services and loans for investments. TradeB has decided to implement an information security management system (ISMS) based on ISO/IEC 27001 Having no experience of a management
[^system implementation, TradeB's top management contracted two experts to direct and manage the ISMS implementation project.
First, the project team analyzed the 93 controls of ISO/IEC 27001 Annex A and listed only the security controls deemed applicable to the company and their objectives Based on this analysis, they drafted the Statement of Applicability. Afterward, they conducted a risk assessment, during which they identified assets, such as hardware, software, and networks, as well as threats and vulnerabilities, assessed potential consequences and likelihood, and determined the level of risks based on three nonnumerical categories (low, medium, and high). They evaluated the risks based on the risk evaluation criteria and decided to treat only the high risk category They also decided to focus primarily on the unauthorized use of administrator rights and system interruptions due to several hardware failures by establishing a new version of the access control policy, implementing controls to manage and control user access, and implementing a control for ICT readiness for business continuity Lastly, they drafted a risk assessment report, in which they wrote that if after the implementation of these security controls the level of risk is below the acceptable level, the risks will be accepted Based on scenario 4, what type of assets were identified during risk assessment?

• A. Primary assets
• B. Business assets
• C. Supporting assets

正解：C

解説：
According to ISO/IEC 27005:2021, there are three types of assets in information security risk management:
primary assets, supporting assets, and business assets. Primary assets are the information and business processes that support the organization's objectives and operations. Supporting assets are the resources that enable the primary assets to function, such as hardware, software, networks, people, facilities, etc. Business assets are the outcomes or benefits that the organization expects from the primary assets, such as reputation, market share, customer satisfaction, etc. (Must be taken from ISO/IEC 27001 : 2022 Lead Implementer resources) In scenario 4, the assets that were identified during risk assessment are hardware, software, and networks, which are examples of supporting assets. These assets are necessary for the information and business processes of TradeB to operate, but they are not the main focus of the risk assessment. The risk assessment should also consider the primary assets and the business assets, as well as the threats and vulnerabilities that affect them, and the potential impacts and likelihood of information security incidents.

Which of the following is NOT part of the steps required by ISO/IEC 27001 that an organization must take when a nonconformity is detected?

• A. Evaluate the need for action to eliminate the causes of the nonconformity so that it does not recur or occur elsewhere
• B. Communicate the details of the nonconformity to every employee of the organization and suspend the employee that caused the nonconformity
• C. React to the nonconformity, take action to control and correct it. and deal with its consequences

正解：B

解説：
According to the ISO/IEC 27001 : 2022 Lead Implementer course, the steps required by ISO/IEC 27001 that an organization must take when a nonconformity is detected are as follows1:
* React to the nonconformity, take action to control and correct it, and deal with its consequences
* Evaluate the need for action to eliminate the causes of the nonconformity so that it does not recur or occur elsewhere
* Implement any action needed
* Review the effectiveness of the corrective action
* Make changes to the information security management system (ISMS) if necessary Therefore, communicating the details of the nonconformity to every employee of the organization and suspending the employee that caused the nonconformity is not part of the steps required by ISO/IEC
27001. This option is not only unnecessary, but also potentially harmful, as it could violate the principles of confidentiality, integrity, and availability of information, as well as the human rights and dignity of the employee involved2. Instead, the organization should follow the established procedures for reporting, recording, and analyzing nonconformities, and ensure that the corrective actions are appropriate, proportional, and fair3.

Refer to scenario 4.

• A. TradeB should evaluate, calculate, and document the value of risk reduction following risk treatment
• B. TradeB should immediately implement new controls to treat all residual risks
• C. TradeB should accept the residual risks only above the acceptance level

正解：A

解説：
According to ISO/IEC 27001 : 2022 Lead Implementer, residual risk is the risk remaining after risk treatment. Residual risk should be compared with the acceptable level of risk, which is the level of risk that the organization is willing to tolerate. If the residual risk is below the acceptable level of risk, then the risk can be accepted. If the residual risk is above the acceptable level of risk, then additional risk treatment options should be considered. Therefore, TradeB should evaluate, calculate, and document the value of risk reduction following risk treatment, which is the difference between the initial risk and the residual risk. This will help TradeB to determine whether the risk treatment was effective and whether the residual risk is acceptable or not.
