Scenario 6: Productscape is a market research company headquartered in Brussels, Belgium. It helps organizations understand the needs and expectations of their customers and identify new business opportunities. Productscape's teams have extensive experience in marketing and business strategy and work with some of the best-known organizations in Europe. The industry in which Productscape operates requires effective risk management. Considering that Productscape has access to clients' confidential information, it is responsible for ensuring its security. As such, the company conducts regular risk assessments. The top management appointed Alex as the risk manager, who is responsible for monitoring the risk management process and treating information security risks.
The last risk assessment conducted was focused on information assets. The purpose of this risk assessment was to identify information security risks, understand their level, and take appropriate action to treat them in order to ensure the security of their systems. Alex established a team of three members to perform the risk assessment activities. Each team member was responsible for specific departments included in the risk assessment scope. The risk assessment provided valuable information to identify, understand, and mitigate the risks that Productscape faces.
Initially, the team identified potential risks based on the risk identification results. Prior to analyzing the identified risks, the risk acceptance criteria were established. The criteria for accepting the risks were determined based on Productscape's objectives, operations, and technology. The team created various risk scenarios and determined the likelihood of occurrence as "low," "medium," or "high." They decided that if the likelihood of occurrence for a risk scenario is determined as "low," no further action would be taken. On the other hand, if the likelihood of occurrence for a risk scenario is determined as "high" or "medium," additional controls will be implemented. Some information security risk scenarios defined by Productscape's team were as follows:
1. A cyber attacker exploits a security misconfiguration vulnerability of Productscape's website to launch an attack, which, in turn, could make the website unavailable to users.
2. A cyber attacker gains access to confidential information of clients and may threaten to make the information publicly available unless a ransom is paid.
3. An internal employee clicks on a link embedded in an email that redirects them to an unsecured website, installing a malware on the device.
The likelihood of occurrence for the first risk scenario was determined as "medium." One of the main reasons that such a risk could occur was the usage of default accounts and password. Attackers could exploit this vulnerability and launch a brute-force attack. Therefore, Productscape decided to start using an automated "build and deploy" process which would test the software on deploy and minimize the likelihood of such an incident from happening. However, the team made it clear that the implementation of this process would not eliminate the risk completely and that there was still a low possibility for this risk to occur. Productscape documented the remaining risk and decided to monitor it for changes.
The likelihood of occurrence for the second risk scenario was determined as "medium." Productscape decided to contract an IT company that would provide technical assistance and monitor the company's systems and networks in order to prevent such incidents from happening.
The likelihood of occurrence for the third risk scenario was determined as "high." Thus, Productscape decided to include phishing as a topic on their information security training sessions. In addition, Alex reviewed the controls of Annex A of ISO/IEC 27001 in order to determine the necessary controls for treating this risk. Alex decided to implement control A.8.23 Web filtering which would help the company to reduce the risk of accessing unsecure websites. Although security controls were implemented to treat the risk, the level of the residual risk still did not meet the risk acceptance criteria defined in the beginning of the risk assessment process. Since the cost of implementing additional controls was too high for the company, Productscape decided to accept the residual risk. Therefore, risk owners were assigned the responsibility of managing the residual risk.
Which risk treatment option was used for the second risk scenario? Refer to scenario 6.
- A. Risk retention
- B. Risk sharing
- C. Risk avoidance
正解：B
解説：
Risk sharing, also known as risk transfer, involves sharing the risk with another party, such as through insurance or outsourcing certain activities to third-party vendors. In Scenario 6, Productscape decided to contract an IT company to provide technical assistance and monitor the company's systems and networks to prevent incidents related to the second risk scenario (gaining access to confidential information and threatening to make it public unless a ransom is paid). This is an example of risk sharing because Productscape transferred part of the risk management responsibilities to an external company. Thus, the correct answer is C, Risk sharing.
Reference:
ISO/IEC 27005:2018, Clause 8.6, "Risk Treatment," which includes risk sharing as an option where a third party is used to manage specific risks.

Scenario 3: Printary is an American company that offers digital printing services. Creating cost-effective and creative products, the company has been part of the printing industry for more than 30 years. Three years ago, the company started to operate online, providing greater flexibility for its clients. Through the website, clients could find information about all services offered by Printary and order personalized products. However, operating online increased the risk of cyber threats, consequently, impacting the business functions of the company. Thus, along with the decision of creating an online business, the company focused on managing information security risks. Their risk management program was established based on ISO/IEC 27005 guidelines and industry best practices.
Last year, the company considered the integration of an online payment system on its website in order to provide more flexibility and transparency to customers. Printary analyzed various available solutions and selected Pay0, a payment processing solution that allows any company to easily collect payments on their website. Before making the decision, Printary conducted a risk assessment to identify and analyze information security risks associated with the software. The risk assessment process involved three phases: identification, analysis, and evaluation. During risk identification, the company inspected assets, threats, and vulnerabilities. In addition, to identify the information security risks, Printary used a list of the identified events that could negatively affect the achievement of information security objectives. The risk identification phase highlighted two main threats associated with the online payment system: error in use and data corruption After conducting a gap analysis, the company concluded that the existing security controls were sufficient to mitigate the threat of data corruption. However, the user interface of the payment solution was complicated, which could increase the risk associated with user errors, and, as a result, impact data integrity and confidentiality.
Subsequently, the risk identification results were analyzed. The company conducted risk analysis in order to understand the nature of the identified risks. They decided to use a quantitative risk analysis methodology because it would provide more detailed information. The selected risk analysis methodology was consistent with the risk evaluation criteri a. Firstly, they used a list of potential incident scenarios to assess their potential impact. In addition, the likelihood of incident scenarios was defined and assessed. Finally, the level of risk was defined as low.
In the end, the level of risk was compared to the risk evaluation and acceptance criteria and was prioritized accordingly.
Based on scenario 3, Printary used a list of identified events that could negatively influence the achievement of its information security objectives to identify information security risks. Is this in compliance with the guidelines of ISO/IEC 27005?
- A. No, a list of risk scenarios with their consequences related to assets or events and their likelihood should be used to identity information security risks
- B. Yes, a list of events that can negatively influence the achievement of information security objectives in the company should be used to identity information security risks
- C. No. a list of risk sources, business processes. and business objectives should be used to identify information security risks
正解：B
解説：
According to ISO/IEC 27005, identifying risks to information security involves recognizing events that could adversely affect the achievement of information security objectives. Using a list of events that could negatively impact these objectives is consistent with the risk identification process as outlined in ISO/IEC 27005. This approach focuses on identifying specific incidents or events that could result in security breaches or compromises, providing a clear understanding of the potential risks to the organization. Thus, Printary's use of a list of such events to identify information security risks complies with the standard's guidelines, making option B the correct answer.
Reference:
ISO/IEC 27005:2018, Clause 8.2, "Risk Identification," which states that the organization should identify the events that could compromise information security objectives.
質問 # 25
What are opportunities?
- A. Outcome of an event affecting objectives
- B. Combination of circumstances expected to be favorable to objectives
- C. Occurrence or change of a particular set of circumstances
正解：B
解説：
Opportunities, according to ISO standards such as ISO 31000, are situations or conditions that have the potential to provide a favorable impact on achieving objectives. They represent circumstances that, when leveraged, can lead to beneficial outcomes for the organization, such as competitive advantage, growth, or improved performance. Option B is correct as it accurately describes opportunities as circumstances expected to be favorable to achieving objectives. Option A (Occurrence or change of a particular set of circumstances) is a more general definition that could apply to both risks and opportunities, while Option C (Outcome of an event affecting objectives) is more aligned with the concept of risk.

質問 # 28
Scenario 7: Adstry is a business growth agency that specializes in digital marketing strategies. Adstry helps organizations redefine the relationships with their customers through innovative solutions. Adstry is headquartered in San Francisco and recently opened two new offices in New York. The structure of the company is organized into teams which are led by project managers. The project manager has the full power in any decision related to projects. The team members, on the other hand, report the project's progress to project managers.
Considering that data breaches and ad fraud are common threats in the current business environment, managing risks is essential for Adstry. When planning new projects, each project manager is responsible for ensuring that risks related to a particular project have been identified, assessed, and mitigated. This means that project managers have also the role of the risk manager in Adstry. Taking into account that Adstry heavily relies on technology to complete their projects, their risk assessment certainly involves identification of risks associated with the use of information technology. At the earliest stages of each project, the project manager communicates the risk assessment results to its team members.
Adstry uses a risk management software which helps the project team to detect new potential risks during each phase of the project. This way, team members are informed in a timely manner for the new potential risks and are able to respond to them accordingly. The project managers are responsible for ensuring that the information provided to the team members is communicated using an appropriate language so it can be understood by all of them.
In addition, the project manager may include external interested parties affected by the project in the risk communication. If the project manager decides to include interested parties, the risk communication is thoroughly prepared. The project manager firstly identifies the interested parties that should be informed and takes into account their concerns and possible conflicts that may arise due to risk communication. The risks are communicated to the identified interested parties while taking into consideration the confidentiality of Adstry's information and determining the level of detail that should be included in the risk communication. The project managers use the same risk management software for risk communication with external interested parties since it provides a consistent view of risks. For each project, the project manager arranges regular meetings with relevant interested parties of the project, they discuss the detected risks, their prioritization, and determine appropriate treatment solutions. The information taken from the risk management software and the results of these meetings are documented and are used for decision-making processes. In addition, the company uses a computerized documented information management system for the acquisition, classification, storage, and archiving of its documents.
Based on the scenario above, answer the following question:
Which of the following documented information management systems does Adstry use?
- A. Content management system
- B. Cloud-based documented management system
- C. Electronic documented management system
正解：C
解説：
Adstry uses a computerized documented information management system for the acquisition, classification, storage, and archiving of documents. This type of system is typically referred to as an Electronic Document Management System (EDMS). An EDMS is designed to handle digital documents and support the management of information, ensuring that documents are stored, retrieved, and maintained efficiently. Option B (Content management system) is incorrect because it primarily manages web content rather than organizational documents. Option C (Cloud-based documented management system) could be partially correct if the EDMS is hosted in the cloud, but the scenario does not specify this.

Scenario 4: In 2017, seeing that millions of people turned to online shopping, Ed and James Cordon founded the online marketplace for footwear called Poshoe. In the past, purchasing pre-owned designer shoes online was not a pleasant experience because of unattractive pictures and an inability to ascertain the products' authenticity. However, after Poshoe's establishment, each product was well advertised and certified as authentic before being offered to clients. This increased the customers' confidence and trust in Poshoe's products and services. Poshoe has approximately four million users and its mission is to dominate the second-hand sneaker market and become a multi-billion dollar company.
Due to the significant increase of daily online buyers, Poshoe's top management decided to adopt a big data analytics tool that could help the company effectively handle, store, and analyze dat a. Before initiating the implementation process, they decided to conduct a risk assessment. Initially, the company identified its assets, threats, and vulnerabilities associated with its information systems. In terms of assets, the company identified the information that was vital to the achievement of the organization's mission and objectives. During this phase, the company also detected a rootkit in their software, through which an attacker could remotely access Poshoe's systems and acquire sensitive data.
The company discovered that the rootkit had been installed by an attacker who had gained administrator access. As a result, the attacker was able to obtain the customers' personal data after they purchased a product from Poshoe. Luckily, the company was able to execute some scans from the target device and gain greater visibility into their software's settings in order to identify the vulnerability of the system.
The company initially used the qualitative risk analysis technique to assess the consequences and the likelihood and to determine the level of risk. The company defined the likelihood of risk as "a few times in two years with the probability of 1 to 3 times per year." Later, it was decided that they would use a quantitative risk analysis methodology since it would provide additional information on this major risk. Lastly, the top management decided to treat the risk immediately as it could expose the company to other issues. In addition, it was communicated to their employees that they should update, secure, and back up Poshoe's software in order to protect customers' personal information and prevent unauthorized access from attackers.
Based on the scenario above, answer the following question:
Poshoe detected a rootkit installed in their software. In which category of threats does this threat belong?
- A. Human actions
- B. Technical failures
- C. Organizational threats
正解：A
解説：
A rootkit installed in software due to an attacker gaining administrator access is considered a threat resulting from human actions. In this scenario, the attacker deliberately exploited a vulnerability to install the rootkit and gain unauthorized access to sensitive data. ISO/IEC 27005 categorizes threats into three main types: technical failures, human actions, and environmental events. Since this threat is a result of intentional malicious activity by an individual (human), it falls under the category of human actions. Option A (Technical failures) would refer to failures in hardware or software that are not caused by deliberate actions, while Option C (Organizational threats) would relate to internal organizational issues, neither of which apply to this case.
質問 # 30
Scenario 5: Detika is a private cardiology clinic in Pennsylvania, the US. Detika has one of the most advanced healthcare systems for treating heart diseases. The clinic uses sophisticated apparatus that detects heart diseases in early stages. Since 2010, medical information of Detika's patients is stored on the organization's digital systems. Electronic health records (EHR), among others, include patients' diagnosis, treatment plan, and laboratory results.
Storing and accessing patient and other medical data digitally was a huge and a risky step for Detik a. Considering the sensitivity of information stored in their systems, Detika conducts regular risk assessments to ensure that all information security risks are identified and managed. Last month, Detika conducted a risk assessment which was focused on the EHR system. During risk identification, the IT team found out that some employees were not updating the operating systems regularly. This could cause major problems such as a data breach or loss of software compatibility. In addition, the IT team tested the software and detected a flaw in one of the software modules used. Both issues were reported to the top management and they decided to implement appropriate controls for treating the identified risks. They decided to organize training sessions for all employees in order to make them aware of the importance of the system updates. In addition, the manager of the IT Department was appointed as the person responsible for ensuring that the software is regularly tested.
Another risk identified during the risk assessment was the risk of a potential ransomware attack. This risk was defined as low because all their data was backed up daily. The IT team decided to accept the actual risk of ransomware attacks and concluded that additional measures were not required. This decision was documented in the risk treatment plan and communicated to the risk owner. The risk owner approved the risk treatment plan and documented the risk assessment results.
Following that, Detika initiated the implementation of new controls. In addition, one of the employees of the IT Department was assigned the responsibility for monitoring the implementation process and ensure the effectiveness of the security controls. The IT team, on the other hand, was responsible for allocating the resources needed to effectively implement the new controls.
Based on scenario 5, which risk treatment option did Detika select to treat the risk of a potential ransomware attack?
- A. Risk retention
- B. Risk sharing
- C. Risk avoidance
正解：A
解説：
Risk retention involves accepting the risk when its likelihood or impact is low, or when the cost of mitigating the risk is higher than the benefit. In the scenario, Detika decided to accept the risk of a potential ransomware attack because the data is backed up daily, and additional measures were deemed unnecessary. This decision aligns with the risk retention strategy, where an organization chooses to live with the risk rather than apply further controls. Option A is the correct answer.
Reference:
ISO/IEC 27005:2018, Clause 8.6, "Risk Treatment," which discusses risk retention as an option for managing risks deemed acceptable by the organization.

According to scenario 4, the top management of Poshoe decided to treat the risk immediately after conducting the risk analysis. Is this in compliance with risk management best practices?
- A. No, the risk should be communicated to all the interested parties before making any decision regarding risk treatment
- B. Yes. risk treatment options should be implemented immediately after analyzing the risk, as the risk could expose the company to other security threats
- C. No, risk evaluation should be performed before making any decision regarding risk treatment
正解：C
解説：
According to ISO/IEC 27005, after conducting risk analysis, the next step in the risk management process should be risk evaluation. Risk evaluation involves comparing the estimated level of risk against risk criteria established by the organization to determine the significance of the risk and decide whether it is acceptable or needs treatment. Only after evaluating the risk should an organization decide on the appropriate risk treatment options. Therefore, in the scenario, deciding to treat the risk immediately after conducting the risk analysis, without first performing a risk evaluation, is not in compliance with risk management best practices. Option A is the correct answer.
Reference:
ISO/IEC 27005:2018, Clause 8.5, "Risk Evaluation," which describes the process of evaluating risks after analysis to determine if they require treatment.

Scenario 8: Biotide is a pharmaceutical company that produces medication for treating different kinds of diseases. The company was founded in 1997, and since then it has contributed in solving some of the most challenging healthcare issues.
As a pharmaceutical company, Biotide operates in an environment associated with complex risks. As such, the company focuses on risk management strategies that ensure the effective management of risks to develop high-quality medication. With the large amount of sensitive information generated from the company, managing information security risks is certainly an important part of the overall risk management process. Biotide utilizes a publicly available methodology for conducting risk assessment related to information assets. This methodology helps Biotide to perform risk assessment by taking into account its objectives and mission. Following this method, the risk management process is organized into four activity areas, each of them involving a set of activities, as provided below.
1. Activity area 1: The organization determines the criteria against which the effects of a risk occurring can be evaluated. In addition, the impacts of risks are also defined.
2. Activity area 2: The purpose of the second activity area is to create information asset profiles. The organization identifies critical information assets, their owners, as well as the security requirements for those assets. After determining the security requirements, the organization prioritizes them. In addition, the organization identifies the systems that store, transmit, or process information.
3. Activity area 3: The organization identifies the areas of concern which initiates the risk identification process. In addition, the organization analyzes and determines the probability of the occurrence of possible threat scenarios.
4. Activity area 4: The organization identifies and evaluates the risks. In addition, the criteria specified in activity area 1 is reviewed and the consequences of the areas of concerns are evaluated. Lastly, the level of identified risks is determined.
The table below provides an example of how Biotide assesses the risks related to its information assets following this methodology:
According to the risk assessment methodology used by Biotide, what else should be performed during activity area 4? Refer to scenario 8.
- A. Create a strategic and operational plan
- B. Monitor security controls for ensuring they are appropriate for new threats
- C. Select a mitigation strategy for the identified risk profiles
正解：C
解説：
In Activity Area 4 of the risk assessment methodology used by Biotide, the focus is on identifying and evaluating risks, reviewing the criteria defined in Activity Area 1, and evaluating the consequences of identified areas of concern to determine the level of risk. However, an essential part of completing a risk assessment process also includes determining appropriate mitigation strategies for the identified risks.
ISO/IEC 27005 provides guidance on selecting and implementing security measures to manage the risk to an acceptable level. Therefore, selecting a mitigation strategy for the identified risk profiles is a crucial next step. This involves deciding on controls or measures that will reduce either the likelihood of the threat exploiting the vulnerability or the impact of the risk should it occur. Thus, the correct answer is B.
Reference:
ISO/IEC 27005:2018, Section 8.3.5 "Risk treatment" outlines the process of selecting appropriate risk treatment options (mitigation strategies) once risks have been identified and evaluated.
質問 # 34
Which of the following statements best defines information security risk?
- A. The potential that threats will exploit vulnerabilities of an information asset and cause harm to an organization
- B. Weakness of an asset or control that can be exploited by one or a group of threats
- C. Potential cause of an unwanted incident related to information security that can cause harm to an organization
正解：A
解説：
Information security risk, as defined by ISO/IEC 27005, is "the potential that a threat will exploit a vulnerability of an asset or group of assets and thereby cause harm to the organization." This definition emphasizes the interplay between threats (e.g., cyber attackers, natural disasters), vulnerabilities (e.g., weaknesses in software, inadequate security controls), and the potential impact or harm that could result from this exploitation. Therefore, option A is the most comprehensive and accurate description of information security risk. In contrast, option B describes a vulnerability, and option C focuses on the cause of an incident rather than defining risk itself. Option A aligns directly with the risk definition in ISO/IEC 27005.
質問 # 35
Which activity below is NOT included in the information security risk assessment process?
- A. Selecting information security risk treatment options
- B. Determining the risk identification approach
- C. Prioritizing risks for risk treatment
正解：A
解説：
The information security risk assessment process, as outlined in ISO/IEC 27005, typically includes identifying risks, assessing their potential impact, and prioritizing them. However, selecting risk treatment options is not part of the risk assessment process itself; it is part of the subsequent risk treatment phase. Therefore, option C is the correct answer as it is not included in the risk assessment process.
