Scenario 7: InfoSec, based in Boston, MA, is a multinational corporation offering professional electronics, gaming, and entertainment products. Following several information security incidents, InfoSec has decided to establish teams of experts 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 implement a screened subnet network architecture. This architecture will isolate the demilitarized zone (DMZ), to which hosted public services are attached, and InfoSec's publicly accessible 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 a thorough evaluation of the nature of an unexpected event, including how the event happened and what or whom it might affect.
On the other hand, Anna will create records of the data, reviews, analyses, and reports to keep evidence for 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.
As part of InfoSec's initiative to strengthen information security measures, Anna will conduct information security risk assessments only when significant changes are proposed and will document the results of these risk assessments. Upon completion of the risk assessment process, Anna is responsible for developing and implementing a plan for treating information security risks and documenting the risk treatment results.
Furthermore, while implementing the communication plan for information security, InfoSec's top management was responsible for creating a roadmap for new product development. This approach helps the company to align its security measures with the product development efforts, demonstrating a commitment to integrating security into every aspect of its business operations.
InfoSec uses a cloud service model that includes cloud-based apps accessed through the web or an application programming interface (API). All cloud services are provided by the cloud service provider, while data is managed by InfoSec. This introduces unique security considerations and becomes a primary focus for the information security team to ensure data and systems are protected in this environment.
Based on this scenario, answer the following question:
Which of the following cloud service models did InfoSec use?
- A. Infrastructure as a Service
- B. Software as a Service
- C. Platform as a Service
正解：B

Then, the ISMS project manager analyzed the list and selected the activities that would allow the elimination of the root cause and the prevention of a similar situation in the future. These activities were included in an action plan The action plan, approved by the top management, was written as follows:
A new version of the access control policy will be established and new restrictions will be created to ensure that network access is effectively managed and monitored by the Information and Communication Technology (ICT) Department The approved action plan was implemented and all actions described in the plan were documented.
Based on scenario 9. did the ISMS project manager complete the corrective action process appropriately?
- A. Yes, the corrective action process should include the identification of the nonconformity, situation analysis, and implementation of corrective actions
- B. No, the corrective action did not address the root cause of the nonconformity
- C. No, the corrective action process should also include the review of the implementation of the selected actions
正解：C
解説：
Explanation
According to ISO/IEC 27001:2022, the corrective action process consists of the following steps12:
Reacting to the nonconformity and, as applicable, taking action to control and correct it and deal with the consequences Evaluating the need for action to eliminate the root cause(s) of the nonconformity, in order that it does not recur or occur elsewhere Implementing the action needed Reviewing the effectiveness of the corrective action taken Making changes to the information security management system, if necessary In scenario 9, the ISMS project manager did not complete the last step of reviewing the effectiveness of the corrective action taken.

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 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, the fact that TradeB defined the level of risk based on three nonnumerical categories indicates that;
- A. The level of risk will be defined using a formula
- B. The level of risk will be evaluated against qualitative criteria
- C. The level of risk will be evaluated using quantitative analysis
正解：B
解説：
Qualitative risk assessment is a method of evaluating risks based on nonnumerical categories, such as low, medium, and high. It is often used when there is not enough data or resources to perform a quantitative risk assessment, which involves numerical values and calculations. Qualitative risk assessment relies on the subjective judgment and experience of the risk assessors, and it can be influenced by various factors, such as thecontext, the stakeholders, and the criteria. According to ISO/IEC 27001:2022, Annex A, control A.8.2.1 states: "The organization shall define and apply an information security risk assessment process that: ... d) identifies the risk owners; e) analyses the risks: i) assesses the consequences that would result if the risks identified were to materialize; ii) assesses the realistic likelihood of the occurrence of the risks; f) identifies and evaluates options for the treatment of risks; g) determines the levels of residual risk and whether these are acceptable; and h) identifies the risk owners for the residual risks." Therefore, TradeB's decision to define the level of risk based on three nonnumerical categories indicates that they used a qualitative risk assessment process.
