NEW QUESTION 167
You are an experienced audit team leader guiding an auditor in training.
Your team is currently conducting a third-party surveillance audit of an organisation that stores data on behalf of external clients. The auditor in training has been tasked with reviewing the TECHNOLOGICAL controls listed in the Statement of Applicability (SoA) and implemented at the site.
Select four controls from the following that would you expect the auditor in training to review.

Confidentiality and nondisclosure agreements

How access to source code and development tools are managed

How power and data cables enter the building

How protection against malware is implemented

How the organisation evaluates its exposure to technical vulnerabilities

Information security awareness, education and training

The organisation’s arrangements for information deletion

The organisation’s business continuity arrangements

The four controls from the list that the auditor in training should review are:
* B. How access to source code and development tools are managed: This control requires the organisation to restrict and monitor the access to the source code and development tools that are used to create, modify, or maintain the software applications and systems that process or store the data of external clients. This is important for ensuring the integrity, confidentiality, and availability of the software and the data, as well as for preventing unauthorized changes, errors, or malicious code injection.
* D. How protection against malware is implemented: This control requires the organisation to implement appropriate measures to detect, prevent, and remove malware from the IT systems and devices that process or store the data of external clients. This includes using antivirus software, firewalls, email filtering, web filtering, and other tools to protect against viruses, worms, ransomware, spyware, and other malicious software. This is essential for safeguarding the data and the systems from corruption, theft, or damage caused by malware.
* E. How the organisation evaluates its exposure to technical vulnerabilities: This control requires the organisation to identify and assess the technical vulnerabilities that may affect the IT systems and devices that process or store the data of external clients. This includes using vulnerability scanning tools, penetration testing tools, threat intelligence sources, and other methods to discover and evaluate the weaknesses and gaps in the security of the systems and the devices. This is necessary for prioritizing and implementing the appropriate corrective actions and controls to mitigate the risks posed by the vulnerabilities.
* G. The organisation’s arrangements for information deletion: This control requires the organisation to establish and implement policies and procedures for deleting the data of external clients from the IT systems and devices when it is no longer needed or required. This includes defining the criteria and methods for data deletion, such as secure erasure, encryption, or physical destruction. This is important for complying with the contractual obligations and the legal and regulatory requirements regarding the retention and disposal of the data, as well as for protecting the confidentiality and integrity of the data.

NEW QUESTION 168
You are the audit team leader conducting a third-party audit of an online insurance company. During Stage 1, you found that the organization took a very cautious risk approach and included all the information security controls in ISO/IEC 27001:2022 Appendix A in their Statement of Applicability.
During the Stage 2 audit, your audit team found that there was no evidence of a risk treatment plan for the implementation of the three controls (5.3 Segregation of duties, 6.1 Screening, 7.12 Cabling security). You raise a nonconformity against clause 6.1.3.e of ISO 27001:2022.
At the closing meeting, the Technical Director issues an extract from an amended Statement of Applicability (as shown) and asks for the nonconformity to be withdrawn.

Select three options of the correct responses of an audit team leader to the request of the Technical Director.

Advise management that the information provided will be reviewed when the auditors have more time.

Advise the Technical Director that his request will be included in the audit report.

Advise the Technical Director that once a nonconformity is raised it cannot be withdrawn.

Advise the Technical Director that the nonconformity must stand since the evidence obtained for it was clear.

Ask the auditor who raised the issue for their opinion on how you should respond to the request.

Inform the Technical Director that the nonconformity will be changed to an Opportunity for Improvement.

Review the documentation produced and withdraw the nonconformity.

State that a follow up audit will be necessary to review the evidence for the updated Statement of Applicability.

The three options of the correct responses of an audit team leader to the request of the Technical Director are:
* B. Advise the Technical Director that his request will be included in the audit report.
* D. Advise the Technical Director that the nonconformity must stand since the evidence obtained for it was clear.
* H. State that a follow up audit will be necessary to review the evidence for the updated Statement of Applicability.
* B. This response is correct because the audit team leader should document the request of the Technical
* Director and include it in the audit report, along with the audit findings and conclusions12. This will ensure transparency and traceability of the audit process and the audit results.
* D. This response is correct because the audit team leader should not withdraw the nonconformity based on the amended Statement of Applicability alone. The nonconformity was raised against clause 6.1.3.e of ISO 27001:2022, which requires the organisation to produce and maintain a risk treatment plan that defines how the information security risks are treated, including the controls selected and their implementation status34. The Statement of Applicability is only one part of the risk treatment plan, and it does not provide sufficient evidence that the controls have been implemented effectively. The audit team leader should base the nonconformity on the objective evidence obtained during the audit, not on the subjective claims of the auditee12.
* H. This response is correct because the audit team leader should state that a follow up audit will be necessary to review the evidence for the updated Statement of Applicability. A follow up audit is an audit that is conducted after a previous audit to verify the implementation and effectiveness of the corrective actions and/or opportunities for improvement that were agreed upon as a result of the previous audit56. The follow up audit should seek to ensure that the nonconformity has been effectively addressed and that the ISMS is compliant and effective. The follow up audit should also consider any new or changed risks or requirements that may affect the ISMS56.

NEW QUESTION 169
You are an audit team leader who has just completed a third-party audit of a mobile telecommunication provider. You are preparing your audit report and are just about to complete a section headed ‘confidentiality’.
An auditor in training on your team asks you if there are any circumstances under which the confidential report can be released to third parties.
Which four of the following responses are false?

Although we advise the client the report is confidential we can decide to release it to third parties if we feel this is justified. We would always tell the client afterwards

The report can be released to third parties but only with the explicit, prior approval of the audit client

There are no circumstances under which the report can be released to a third party. Confidential means confidential and releasing the document would be a breach of trust

The starting position is always that third parties have no automatic right to access an audit report

If the third party has gained a legal notice for us to disclose the report then we must do so. In all such cases we would advise the audit client and, as appropriate, the auditee

Any auditor employed by the auditing organisation can access the audit report

Our duty of confidentiality is not something that lasts forever. As a certification body, we can decide how long we wish to keep reports confidential. After this, they can be accessed by third parties making a subject access request

Subcontracted auditors are considered to be third parties regarding confidentiality and are therefore typically bound by confidentiality agreements

The audit report is a confidential document that contains sensitive information about the auditee’s ISMS and its performance. The audit team has a duty to protect the confidentiality of the audit report and only disclose it to authorized parties, such as the audit client, the certification body, and the accreditation body. Therefore, the following responses are false:
* A: The audit team cannot decide to release the report to third parties without the consent of the audit client, as this would breach the confidentiality agreement and the audit code of conduct. The audit team should always inform the audit client before disclosing the report to any third party, and obtain their explicit, prior approval.
* F: Not every auditor employed by the auditing organization can access the audit report, as this would violate the principle of need-to-know. Only auditors who are involved in the audit process, such as the audit team leader, the audit team members, the audit programme manager, and the certification decision maker, can access the audit report. Other auditors who are not related to the audit have no legitimate reason to access the report, and should be prevented from doing so by appropriate security measures.
* G: The duty of confidentiality does not expire after a certain period of time, as this would compromise the trust and integrity of the audit process. The audit report remains confidential indefinitely, unless
* there is a legal or contractual obligation to disclose it, or the audit client agrees to release it. Third parties cannot access the audit report by making a subject access request, as this would infringe the privacy and data protection rights of the audit client and the auditee.
* H: Subcontracted auditors are not considered to be third parties regarding confidentiality, as they are part of the audit team and have a contractual relationship with the auditing organization. Subcontracted auditors are typically bound by the same confidentiality agreement and audit code of conduct as the employed auditors, and have the same rights and responsibilities to access and protect the audit report.

NEW QUESTION 172
You are an experienced ISMS audit team leader providing instruction to a class of auditors in training. The subject of today’s lesson is the management of information security risk in accordance with the requirements of ISO/IEC 27001:2022.
You provide the class with a series of activities. You then ask the class to sort these activities into the order in which they appear in the standard.
What is the correct sequence they should report back to you?

NEW QUESTION 173
You are an experienced ISMS internal auditor.
You have just completed a scheduled information security audit of your organisation when the IT Manager approaches you and asks for your assistance in the revision of the company’s Statement of Applicability.
The IT Manager is attempting to update the ISO/IEC 27001:2013 based Statement of Applicability to a Statement aligned to the 4 control themes present in ISO/IEC 27001:2022 (Organizational controls, People Controls, Physical Controls, Technical Controls).
The IT Manager is happy with their reassignment of controls, with the following exceptions. He asks you which of the four control categories each of the following should appear under.

NEW QUESTION 174
You ask the IT Manager why the organisation still uses the mobile app while personal data encryption and pseudonymization tests failed. Also, whether the Service Manager is authorized to approve the test.
The IT Manager explains the test results should be approved by him according to the software security management procedure. The reason why the encryption and pseudonymization functions failed is that these functions heavily slowed down the system and service performance. An extra 150% of resources are needed to cover this. The Service Manager agreed that access control is good enough and acceptable. That’s why the Service Manager signed the approval.
You sample one of the medical staff’s mobile and found that ABC’s healthcare mobile app, version 1.01 is installed. You found that version 1.01 has no test record.
The IT Manager explains that because of frequent ransomware attacks, the outsourced mobile app development company gave a free minor update on the tested software, performed an emergency release of the updated software, and gave a verbal guarantee that there will be no impact on any security functions. Based on his 20 years of information security experience, there is no need to re-test.
You are preparing the audit findings Select two options that are correct.

There is NO nonconformity (NC). The IT Manager demonstrates he is fully competent. (Relevant to clause 7.2)

There is a nonconformity (NC). The IT Manager does not comply with the software security management procedure. (Relevant to clause 8.1, control A.8.30)

There is a nonconformity (NC). The organisation does not control planned changes and review the consequences of unintended changes. (Relevant to clause 8.1)

There is an opportunity for improvement (OI). The organisation selects an external service provider based on the extent of free services it will provide. (Relevant to clause 8.1, control A.5.21)

There is NO nonconformity (NC). The IT Manager demonstrates good leadership. (Relevant to clause
5.1, control 5.4)

There is an opportunity for improvement (OI). The IT Manager should make the decision to continue the service based on appropriate testing. (Relevant to clause 8.1, control A.8.30)

According to ISO 27001:2022 Annex A Control 8.30, the organisation shall ensure that externally provided processes, products or services that are relevant to the information security management system are controlled. This includes developing and entering into licensing agreements that cover code ownership and intellectual property rights, and implementing appropriate contractual requirements related to secure design and coding in accordance with Annex A 8.25 and 8.2912 In this case, the organisation and the developer have performed security tests that failed, which indicates that the secure design and coding requirements of Annex A 8.29 were not met. The IT Manager explains that the encryption and pseudonymization functions failed because they slowed down the system and service performance, and that an extra 150% of resources are needed to cover this. However, this does not justify the acceptance of the test results by the Service Manager, who is not authorised to approve the test according to the software security management procedure. The Service Manager should have consulted with the IT Manager, who is the owner of the process, and followed the procedure for handling nonconformities and corrective actions. The Service Manager’s decision to continue the service based on access control alone exposes the organisation to the risk of compromising the confidentiality, integrity, and availability of personal data processed by the mobile app. Therefore, there is a nonconformity (NC) with clause 8.1, control A.8.30.
According to ISO 27001:2022 Clause 8.1, the organisation shall plan, implement and control the processes needed to meet information security requirements, and to implement the actions determined in Clause 6.1. The organisation shall also control planned changes and review the consequences of unintended changes, taking action to mitigate any adverse effects, as necessary12 In this case, the organisation has not controlled the planned change of the mobile app from version 1.0 to version 1.01, which was a minor update provided by the outsourced developer in response to frequent ransomware attacks. The IT Manager explains that the developer performed an emergency release of the updated software, and gave a verbal guarantee that there will be no impact on any security functions.
However, this is not sufficient to ensure that the change is properly assessed, tested, documented, and approved before deployment. The IT Manager should have followed the change management process and procedure, and verified that the updated software meets the security requirements and does not introduce any new vulnerabilities or risks. The IT Manager’s reliance on his 20 years of information security experience and the developer’s verbal guarantee is not a valid basis for skipping the re-testing of the software. Therefore, there is a nonconformity (NC) with clause 8.1.

NEW QUESTION 184
You are carrying out your first third-party ISMS surveillance audit as an Audit Team Leader. You are presently in the auditee’s data centre with another member of your audit team.
Your colleague seems unsure as to the difference between an information security event and an information security incident. You attempt to explain the difference by providing examples.
Which three of the following scenarios can be defined as information security incidents?

The organisation’s malware protection software prevents a virus

A hard drive is used after its recommended replacement date

The organisation receives a phishing email

An employee fails to clear their desk at the end of their shift

A contractor who has not been paid deletes top management ICT accounts

An unhappy employee changes payroll records without permission

The organisation fails a third-party penetration test

The organisation’s marketing data is copied by hackers and sold to a competitor

Explanation
According to ISO/IEC 27000:2018, which provides an overview and vocabulary of information security management systems, an information security event is an identified occurrence of a system, service or network state indicating a possible breach of information security policy or failure of safeguards, or a previously unknown situation that may be security relevant1. An information security incident is a single or a series of unwanted or unexpected information security events that have a significant probability of compromising business operations and threatening information security1. Therefore, based on this definition, three examples of information security incidents are:
* A contractor who has not been paid deletes top management ICT accounts: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in loss of access, data, or functionality for the top management.
* An unhappy employee changes payroll records without permission: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in financial fraud, legal liability, or reputational damage for the organization.
* The organisation’s marketing data is copied by hackers and sold to a competitor: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in loss of confidentiality, competitive advantage, or customer trust for the organization.
The other options are not examples of information security incidents, but rather information security events that may or may not lead to incidents depending on their impact and severity. For example:
* The organisation’s malware protection software prevents a virus: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, as it is prevented by the malware protection software.
* A hard drive is used after its recommended replacement date: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless it fails or causes other problems.
* The organisation receives a phishing email: This is an example of an identified occurrence of a network state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless it is opened or responded to by the recipient.
* An employee fails to clear their desk at the end of their shift: This is an example of an identified occurrence of a service state indicating a possible breach of information security policy or failure of
* safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless the desk contains sensitive or confidential information that is accessed by unauthorized persons.
* The organisation fails a third-party penetration test: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless the penetration test reveals serious vulnerabilities that are exploited by malicious actors.

NEW QUESTION 185
In the context of a management system audit, please identify the sequence of a typical process of collecting and verifying information. The first one has been done for you.

NEW QUESTION 186
The auditor used sampling to ensure that event logs recording information security events are maintained and regularly reviewed. Sampling was based on the audit objectives, whereas the sample selection process was based on the probability theory. What type of sampling was used?

Statistical sampling

Judgment-based sampling

Systematic sampling

NEW QUESTION 187
