Question No. 1

You are an experienced ISMS audit team leader. You are providing an introduction to ISO/IEC 27001:2022 to a class of Quality Management System Auditors who are seeking to retrain to enable them to carry out information security management system audits.

You ask them which of the following characteristics of information does an information security management system seek to preserve?

Which three answers should they provide?

Show Answer Hide Answer
Correct Answer: E, F, G

These three characteristics are the fundamental properties of information security, as defined by the ISO/IEC 27000 standard, which provides the overview and vocabulary of information security, cybersecurity, and privacy protection12. They are also the basis for the information security objectives and controls of the ISO/IEC 27001 standard, which specifies the requirements for establishing, implementing, maintaining, and continually improving an information security management system34. The definitions of these characteristics are as follows12:

* Availability: The property of being accessible and usable upon demand by an authorized entity.

* Confidentiality: The property that information is not made available or disclosed to unauthorized individuals, entities, or processes.

* Integrity: The property of safeguarding the accuracy and completeness of information and processing methods.

The other characteristics listed in the question, such as clarity, accessibility, completeness, importance, and efficiency, are not directly related to information security, although they may be relevant for other aspects of information management, such as quality, usability, or performance.


Question No. 2

Scenario 4: SendPay is a financial company that provides its services through a network of agents and financial institutions. One of their main services is transferring money worldwide. SendPay, as a new company, seeks to offer top quality services to its clients. Since the company offers international transactions, it requires from their clients to provide personal information, such as their identity, the reason for the transactions, and other details that might be needed to complete the transaction. Therefore, SendPay has implemented security measures to protect their clients' information, including detecting, investigating, and responding to any information security threats that may emerge. Their commitment to offering secure services was also reflected during the ISMS implementation where the company invested a lot of time and resources.

Last year, SendPay unveiled their digital platform that allows money transactions through electronic devices, such as smartphones or laptops, without requiring an additional fee. Through this platform, SendPay's clients can send and receive money from anywhere and at any time. The digital platform helped SendPay to simplify the company's operations and further expand its business. At the time, SendPay was outsourcing its software operations, hence the project was completed by the software development team of the outsourced company. The same team was also responsible for maintaining the technology infrastructure of SendPay.

Recently, the company applied for ISO/IEC 27001 certification after having an ISMS in place for almost a year. They contracted a certification body that fit their criteri

a. Soon after, the certification body appointed a team of four auditors to audit SendPay's ISMS.

During the audit, among others, the following situations were observed:

1. The outsourced software company had terminated the contract with SendPay without prior notice. As a result, SendPay was unable to immediately bring the services back in-house and its operations were disrupted for five days. The auditors requested from SendPay's representatives to provide evidence that they have a plan to follow in cases of contract terminations. The representatives did not provide any documentary evidence but during an interview, they told the auditors that the top management of SendPay had identified two other software development companies that could provide services immediately if similar situations happen again.

2. There was no evidence available regarding the monitoring of the activities that were outsourced to the software development company. Once again, the representatives of SendPay told the auditors that they regularly communicate with the software development company and that they are appropriately informed for any possible change that might occur.

3. There was no nonconformity found during the firewall testing. The auditors tested the firewall configuration in order to determine the level of security provided by

these services. They used a packet analyzer to test the firewall policies which enabled them to check the packets sent or received in real-time.

Based on this scenario, answer the following question:

How do you evaluate the evidence obtained related to the monitoring process of outsourced operations? Refer to scenario 4.

Show Answer Hide Answer
Correct Answer: B

The evidence provided by SendPay, which is solely verbal confirmation about the monitoring of outsourced operations, is not considered reliable under ISO/IEC 27001. The standard requires documented evidence to support claims of effective monitoring and control over outsourced processes.


Question No. 3

Scenario 9: UpNet, a networking company, has been certified against ISO/IEC 27001. It provides network security, virtualization, cloud computing, network hardware, network management software, and networking technologies.

The company's recognition has increased drastically since gaining ISO/IEC 27001 certification. The certification confirmed the maturity of UpNefs operations and its compliance with a widely recognized and accepted standard.

But not everything ended after the certification. UpNet continually reviewed and enhanced its security controls and the overall effectiveness and efficiency of the ISMS by conducting internal audits. The top management was not willing to employ a full-time team of internal auditors, so they decided to outsource the internal audit function. This form of internal audits ensured independence, objectivity, and that they had an advisory role about the continual improvement of the ISMS.

Not long after the initial certification audit, the company created a new department specialized in data and storage products. They offered routers and switches optimized for data centers and software-based networking devices, such as network virtualization and network security appliances. This caused changes to the operations of the other departments already covered in the ISMS certification scope.

Therefore. UpNet initiated a risk assessment process and an internal audit. Following the internal audit result, the company confirmed the effectiveness and efficiency of the existing and new processes and controls.

The top management decided to include the new department in the certification scope since it complies with ISO/IEC 27001 requirements. UpNet announced that it is ISO/IEC 27001 certified and the certification scope encompasses the whole company.

One year after the initial certification audit, the certification body conducted another audit of UpNefs ISMS. This audit aimed to determine the UpNefs ISMS fulfillment of specified ISO/IEC 27001 requirements and ensure that the ISMS is being continually improved. The audit team confirmed that the certified ISMS continues to fulfill

the requirements of the standard. Nonetheless, the new department caused a significant impact on governing the management system. Moreover, the certification body was not informed about any changes. Thus, the UpNefs certification was suspended.

Based on the scenario above, answer the following question:

UpNet announced that the ISMS certification scope encompasses the whole company once ensuring that the new department also complies with the ISO/IEC 27001 requirements. How would you classify this situation illustrated in scenario 9?

Show Answer Hide Answer
Correct Answer: B

This situation is unacceptable because UpNet should have requested and been granted an extension audit prior to announcing that the ISMS certification scope encompasses the whole company, including the new department. Proper procedures need to be followed to extend the certification to additional departments or processes.

Which two of the following statements are true?

Show Answer Hide Answer
Correct Answer: D, E

The benefits of implementing an ISMS primarily result from a reduction in information security risks. E. The purpose of an ISMS is to apply a risk management process for preserving information security. Comprehensive and Detailed Explanation: According to the ISO 27001 standard, the benefits of implementing an ISMS include the following1:

Assuring customers and other stakeholders of the confidentiality, integrity and availability of information

Enhancing the ability to respond to information security incidents and minimize their impacts

Improving the governance and management of information security

Reducing the costs and losses associated with information security breaches

Increasing the competitiveness and reputation of the organization

Complying with legal, regulatory and contractual obligations The purpose of an ISMS is to provide a systematic approach to managing information security risks, based on the Plan-Do-Check-Act (PDCA) cycle1. The ISMS enables the organization to establish, implement, maintain and continually improve its information security performance, in alignment with its business objectives and the needs and expectations of interested parties1. The ISMS consists of the following elements1:

The information security policy and objectives

The scope and boundaries of the ISMS

The processes and procedures for information security risk assessment and treatment

The resources and competencies for information security

The roles and responsibilities for information security

The performance evaluation and improvement of the ISMS

Question No. 5

All are prohibited in acceptable use of information assets, except:

Show Answer Hide Answer
Correct Answer: C

The only option that is not prohibited in acceptable use of information assets is C: company-wide e-mails with supervisor/TL permission. This option implies that the sender has obtained the necessary authorization from their supervisor or team leader to send an e-mail to all employees in the organization. This could be done for legitimate business purposes, such as announcing important news, events or updates that are relevant to everyone. However, this option should still be used sparingly and responsibly, as it could cause unnecessary disruption or annoyance to the recipients if abused or misused. The other options are prohibited in acceptable use of information assets, as they could violate the information security policies and procedures of the organization, as well as waste resources and bandwidth. Electronic chain letters (A) are messages that urge recipients to forward them to multiple other people, often with false or misleading claims or promises. They are considered spam and could contain malicious links or attachments that could compromise information security. E-mail copies to non-essential readers (B) are messages that are sent to recipients who do not need to receive them or have no interest in them. They are considered unnecessary and could clutter the inbox and distract the recipients from more important messages. Messages with very large attachments or to a large number of recipients (D) are messages that consume a lot of network resources and could affect the performance or availability of the information systems. They could also exceed the storage capacity or quota limits of the recipients' mailboxes and cause problems for them. ISO/IEC 27001:2022 requires the organization to implement rules for acceptable use of assets (see clause A.8.1.3).Reference:CQI & IRCA Certified ISO/IEC 27001:2022 Lead Auditor Training Course,ISO/IEC 27001:2022 Information technology --- Security techniques --- Information security management systems --- Requirements,What is Acceptable Use?
