Questions # 41:

Scenario 1:

HealthGenic is a leading multi-specialty healthcare organization providing patients with comprehensive medical services in Toronto, Canada. The organization relies heavily on a web-based medical software platform to monitor patient health, schedule appointments, generate customized medical reports, securely store patient data, and facilitate seamless communication among various stakeholders, including patients, physicians, and medical laboratory staff.

As the organization expanded its services and demand grew, frequent and prolonged service interruptions became more common, causing significant disruptions to patient care and administrative processes. As such, HealthGenic initiated a comprehensive risk analysis to assess the severity of risks it faced.

When comparing the risk analysis results with its risk criteria to determine whether the risk and its significance were acceptable or tolerable, HealthGenic noticed a critical gap in its capacity planning and infrastructure resilience. Recognizing the urgency of this issue, HealthGenic reached out to the software development company responsible for its platform. Utilizing its expertise in healthcare technology, data management, and compliance regulations, the software development company successfully resolved the service interruptions.

However, HealthGenic also uncovered unauthorized changes to user access controls. Consequently, some medical reports were altered, resulting in incomplete and inaccurate medical records. The company swiftly acknowledged and corrected the unintentional changes to user access controls. When analyzing the root cause of these changes, HealthGenic identified a vulnerability related to the segregation of duties within the IT department, which allowed individuals with system administration access also to manage user access controls. Therefore, HealthGenic decided to prioritize controls related to organizational structure, including segregation of duties, job rotations, job descriptions, and approval processes.

In response to the consequences of the service interruptions, the software development company revamped its infrastructure by adopting a scalable architecture hosted on a cloud platform, enabling dynamic resource allocation based on demand. Rigorous load testing and performance optimization were conducted to identify and address potential bottlenecks, ensuring the system could handle increased user loads seamlessly. Additionally, the company promptly assessed the unauthorized access and data alterations.

To ensure that all employees, including interns, are aware of the importance of data security and the proper handling of patient information, HealthGenic included controls tailored to specifically address employee training, management reviews, and internal audits. Additionally, given the sensitivity of patient data, HealthGenic implemented strict confidentiality measures, including robust authentication methods, such as multi-factor authentication.

In response to the challenges faced by HealthGenic, the organization recognized the vital importance of ensuring a secure cloud computing environment. It initiated a comprehensive self-assessment specifically tailored to evaluate and enhance the security of its cloud infrastructure and practices.

According to scenario 1, what is the possible threat associated with the vulnerability discovered by HealthGenic when analyzing the root cause of unauthorized changes?

Options:

Theft

Lawsuit

Fraud

Questions # 42:

An organization has justified the exclusion of control 5.18 Access rights of ISO/IEC 27001 in the Statement of Applicability (SoA) as follows: "An access control reader is already installed at the main entrance of the building." Which statement is correct'

Options:

The justification for the exclusion of a control is not required to be included in the SoA

The justification is not acceptable, because it does not reflect the purpose of control 5.18

The justification is not acceptable because it does not indicate that it has been selected based on the risk assessment results

Answer

Explanation

According to ISO/IEC 27001:2022, clause 6.1.3, the Statement of Applicability (SoA) is a document that identifies the controls that are applicable to the organization’s ISMS and explains why they are selected or not. The SoA is based on the results of the risk assessment and risk treatment, which are the previous steps in the risk management process. Therefore, the justification for the exclusion of a control should be based on the risk assessment results and the risk treatment plan, and should reflect the purpose and objective of the control.

Control 5.18 of ISO/IEC 27001:2022 is about access rights to information and other associated assets, which should be provisioned, reviewed, modified and removed in accordance with the organization’s topic-specific policy on and rules for access control. The purpose of this control is to prevent unauthorized access to, modification of, and destruction of information assets. Therefore, the justification for the exclusion of this control should explain why the organization does not need to implement this control to protect its information assets from unauthorized access.

The justification given by the organization in the question is not acceptable, because it does not reflect the purpose of control 5.18. An access control reader at the main entrance of the building is a physical security measure, which is related to control 5.15 of ISO/IEC 27001:2022, not control 5.18. Control 5.18 is about logical access rights to information systems and services, which are not addressed by the access control reader. Therefore, the organization should either provide a valid justification for the exclusion of control 5.18, or include it in the SoA and implement it according to the risk assessment and risk treatment results.

Questions # 43:

Refer to Scenario 4 (FinSecure)

Finsecure is a financial institution based in Finland, providing services to a diverse clientele, encompassing retail banking, corporate banking, wealth management, and digital banking, all tailored to meet the evolving financial needs of individuals and businesses in the region. Recognizing the critical importance of information security in the modern banking landscape, FinSecure has initiated the implementation of an information security management system (ISMS) based on ISO/IEC 27001. To ensure the successful implementation of the ISMS, the top management decided to contract two experts to lead and oversee the ISMS implementation project.

As a primary strategy for implementing the ISMS, the experts chose an approach that emphasizes a swift implementation of the ISMS by initially meeting the minimum requirements of ISO/IEC 27001, followed by continual improvement over time. Additionally, under the guidance of experts, FinSecure opted for a methodological framework, which serves as a structured framework that outlines the high-level stages of the ISMS implementation, the associated activities, and the deliverables without incorporating any specific tools.

The experts conducted a risk assessment, identifying all the supporting assets, which were the most tangible ones. They assessed the potential consequences and likelihood of various risks, determining the level of risks using a methodical approach that involved defining and characterizing the terms and criteria used in the assessment process. These risks were categorized into nonnumerical levels (e g., very low, low. moderate, high, very high). Explanatory notes were thoughtfully crafted to justify assessed values, with the primary goal of enhancing repeatability and reproducibility.

After completing the risk assessment, the experts reviewed a selected number of the security controls from Annex A of ISO/IEC 27001 to determine which ones were applicable to the company's specific context. The decision to implement security controls was justified by the risk assessment results. Based on this review, they drafted the Statement of Applicability (SoA). They focused on treating only the high-risk category particularly addressing unauthorized use of administrator rights and system interruptions due to several hardware failures. To address these issues, they established a new version of the access control policy, implemented controls to manage and control user access, and introduced a control for ICT readiness to ensure business continuity.

Their risk assessment report indicated that if the implemented security controls reduce the risk levels to an acceptable threshold, those risks will be accepted

Question:

Did the experts draft the Statement of Applicability (SoA) in accordance with ISO/IEC 27001?

Options:

Yes – because they reviewed a selected number of the controls from Annex A of ISO/IEC 27001

No – because they did not review all of the controls from Annex A of ISO/IEC 27001

No – because the SoA should have been drafted just before the risk assessment was finalized

Questions # 44:

A small organization that is implementing an ISMS based on ISO/lEC 27001 has decided to outsource the internal audit function to a third party. Is this acceptable?

Options:

Yes, outsourcing the internal audit function to a third party is often a better option for small organizations to demonstrate independence and impartiality

No, the organizations cannot outsource the internal audit function to a third party because during internal audit, the organization audits its own system

No, the outsourcing of the internal audit function may compromise the independence and impartiality of the internal audit team

Answer

Explanation

According to the ISO/IEC 27001:2022 standard, an internal audit is an audit conducted by the organization itself to evaluate the conformity and effectiveness of its information security management system (ISMS). The standard requires that the internal audit should be performed by auditors who are objective and impartial, meaning that they should not have any personal or professional interest or bias that could influence their judgment or compromise their integrity. The standard also allows the organization to outsource the internal audit function to a third party, as long as the criteria of objectivity and impartiality are met.

Outsourcing the internal audit function to a third party can be a better option for small organizations that may not have enough resources, skills, or experience to perform an internal audit by themselves. By hiring an external auditor, the organization can benefit from the following advantages:

The external auditor can provide a fresh and independent perspective on the organization’s ISMS, identifying strengths, weaknesses, opportunities, and threats that may not be apparent to the internal staff.

The external auditor can bring in specialized knowledge, expertise, and best practices from other organizations and industries, helping the organization to improve its ISMS and achieve its objectives.

The external auditor can reduce the risk of conflict of interest, bias, or influence that may arise when the internal staff audit their own work or the work of their colleagues.

The external auditor can save the organization time and money by conducting the internal audit more efficiently and effectively, avoiding duplication of work or unnecessary delays.

Therefore, outsourcing the internal audit function to a third party is acceptable and often preferable for small organizations that are implementing an ISMS based on ISO/IEC 27001.

Scenario 10: NetworkFuse develops, manufactures, and sells network hardware. The company has had an operational information security management system (ISMS) based on ISO/IEC 27001 requirements and a quality management system (QMS) based on ISO 9001 for approximately two years. Recently, it has applied for a j^ombined certification audit in order to obtain certification against ISO/IEC 27001 and ISO 9001.

After selecting the certification body, NetworkFuse prepared the employees for the audit The company decided to not conduct a self-evaluation before the audit since, according to the top management, it was not necessary. In addition, it ensured the availability of documented information, including internal audit reports and management reviews, technologies in place, and the general operations of the ISMS and the QMS. However, the company requested from the certification body that the documentation could not be carried off-site

However, the audit was not performed within the scheduled days because NetworkFuse rejected the audit team leader assigned and requested their replacement The company asserted that the same audit team leader issued a recommendation for certification to its main competitor, which, for the company's top management, was a potential conflict of interest. The request was not accepted by the certification body

The certification body rejected NetworkFuse's request to change the audit team leader. Is this acceptable? Refer to scenario 10.
