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 relevantagreements, 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.

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.
Socket Inc. has implemented a control for the effective use of cryptography and cryptographic key management. Is this compliant with ISO/IEC 27001' Refer to scenario 3.
- A. No, because the standard provides a separate control for cryptographic key management
- B. No, the control should be implemented only for defining rules for cryptographic key management
- C. Yes, the control for the effective use of the cryptography can include cryptographic key management
正解：C
解説：
According to ISO/IEC 27001:2022, Annex A.8.24, the control for the effective use of cryptography is intended to ensure proper and effective use of cryptography to protect the confidentiality, authenticity, and/or integrity of information. This control can include cryptographic key management, which is the process of generating, distributing, storing, using, and destroying cryptographic keys in a secure manner. Cryptographic key management is essential for ensuring the security and functionality of cryptographic solutions, such as encryption, digital signatures, or authentication.
The standard provides the following guidance for implementing this control:
* A policy on the use of cryptographic controls should be developed and implemented.
* The policy should define the circumstances and conditions in which the different types of cryptographic controls should be used, based on the information classification scheme, the relevant agreements, legislation, and regulations, and the assessed risks.
* The policy should also define the standards and techniques to be used for each type of cryptographic control, such as the algorithms, key lengths, key formats, and key lifecycles.
* The policy should be reviewed and updated regularly to reflect the changes in the technology, the business environment, and the legal requirements.
* The cryptographic keys should be managed through their whole lifecycle, from generation to destruction, in a secure and controlled manner, following the principles of need-to-know and segregation of duties.
* The cryptographic keys should be protected from unauthorized access, disclosure, modification, loss, or theft, using appropriate physical and logical security measures, such as encryption, access control, backup, and audit.
* The cryptographic keys should be changed or replaced periodically, or when there is a suspicion of compromise, following a defined process that ensures the continuity of the cryptographic services and the availability of the information.
* The cryptographic keys should be securely destroyed when they are no longer required, or when they reach their end of life, using methods that prevent their recovery or reconstruction.

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 What should TradeB do in order to deal with residual risks? Refer to scenario 4.
- A. TradeB should accept the residual risks only above the acceptance level
- B. TradeB should immediately implement new controls to treat all residual risks
- C. TradeB should evaluate, calculate, and document the value of risk reduction following risk treatment
正解：C
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.

FinanceX, a well-known financial institution, uses an online banking platform that enables clients to easily and securely access their bank accounts. To log in, clients are required to enter the one-lime authorization code sent to their smartphone. What can be concluded from this scenario?
- A. FinanceX has incorrectly implemented a security control that could become a vulnerability
- B. FinanceX has implemented a securityControl that ensures the confidentiality of information
- C. FinanceX has implemented an integrity control that avoids the involuntary corruption of data
正解：B
解説：
Confidentiality is the property that information is not made available or disclosed to unauthorized individuals, entities, or processes. A security control is a measure that is put in place to protect the confidentiality, integrity, and availability of informationassets. In this scenario, FinanceX has implemented a security control that ensures the confidentiality of information by requiring clients to enter a one-time authorization code sent to their smartphone when they log in to their online banking platform. This control prevents unauthorized access to the clients' bank accounts and protects their sensitive information from being disclosed to third parties. The one-time authorization code is a form of two-factor authentication, which is a security technique that requires two pieces of evidence to verify the identity of a user. In this case, the two factors are something the user knows (their username and password) and something the user has (their smartphone). Two-factor authentication is a recommended security control for online banking platforms, as it provides a higher level of security than single-factor authentication, which relies only on one piece of evidence, such as a password.
