According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), an organization should select and implement appropriate controls to achieve its information security objectives1. The controls should be derived from the results of risk assessment and risk treatment, and should be consistent with the Statement of Applicability (SoA), which is a document that identifies the controls that are applicable and necessary for the ISMS1. The controls can be selected from various sources, such as ISO/IEC 27002:2013, which provides a code of practice for information security controls2. Therefore, if an auditor in training has been tasked with reviewing the technological controls listed in the SoA and implemented at the site of an organization that stores data on behalf of external clients, four controls that would be expected to review are:
* How protection against malware is implemented: This is a technological control that aims to prevent, detect and remove malicious software (such as viruses, worms, ransomware, etc.) that could compromise the confidentiality, integrity or availability of information or information systems2. This control is related to control A.12.2.1 of ISO/IEC 27002:20132.
* How the organisation evaluates its exposure to technical vulnerabilities: This is a technological control that aims to identify and assess the potential weaknesses or flaws in information systems or networks that could be exploited by malicious actors or cause accidental failures2. This control is related to control A.12.6.1 of ISO/IEC 27002:20132.
* How access to source code and development tools are managed: This is a technological control that aims to protect the intellectual property rights and integrity of software applications or systems that are developed or maintained by the organization or its external providers2. This control is related to control A:14.2.5 of ISO/IEC 27002:20132.
* The operation of the site CCTV and door control systems: This is a technological control that aims to monitor and restrict physical access to the premises or facilities where information or information systems are stored or processed2. This control is related to control A.11.1.4 of ISO/IEC 27002:20132.
The other options are not examples of technological controls, but rather organizational, legal or procedural controls that may also be relevant for an ISMS audit, but are not within the scope of the auditor in training's task. For example, the development and maintenance of an information asset inventory (related to control A.
8.1.1), rules for transferring information within the organization and to other organizations (related to control A.13.2.1), confidentiality and nondisclosure agreements (related to control A.13.2.4), verification checks on personnel (related to control A.7.1.2), remote working arrangements (related to control A.6.2.1), information security within supplier agreements (related to control A.15.1.1), business continuity arrangements (related to control A.17), information deletion (related to control A.8.3), information security awareness, education and training (related to control A.7.2), equipment maintenance (related to control A.11.2), and how power and data cables enter the building (related to control A.11) are not technological controls, but rather organizational, legal or procedural controls that may also be relevant for an ISMS audit, but are not within the scope of the auditor in training's task.

ISO/IEC 27001 focuses on the core principles of the CIA triad:
* Confidentiality: Ensuring information is accessible only to authorized individuals.
* Integrity: Maintaining the accuracy and completeness of information, protecting it from unauthorized modification.
* Availability: Information should be accessible to authorized users when needed (this is also important, but not one of the choices in this specific question).
Reference:
* ISO/IEC 27001:2022, Section 4.2 (Understanding the needs and expectations of interested parties): This section highlights the importance of determining relevant interested parties and their requirements related to information security, which includes addressing confidentiality, integrity, and availability.

In the context of ISO/IEC 27001 audits, the audit team is appointed by the certification body, not by the organization being audited. Data Grid Inc. is responsible for specifying the audit criteria and defining the audit scope, but not for appointing the audit team.

According to ISO 19011:2018, which provides guidelines for auditing management systems, a sampling plan is a method for selecting a representative subset of the audit evidence from a defined population1. A sampling plan can have several advantages for the audit, such as providing a suitable understanding of the ISMS by covering its key processes, activities, and controls; implementing the audit plan efficiently by optimizing the use of time and resources; and giving confidence in the audit results by ensuring that the sample is sufficient, reliable, and unbiased1. Therefore, these three options are examples of advantages of using a sampling plan for the audit. The other options are not advantages, but rather disadvantages or risks of using a sampling plan. For example, overruling the auditor's instincts may lead to missing important evidence or issues that are not covered by the sampling plan; using the same plan for consecutive audits may reduce the effectiveness and validity of the audit results; and missing key issues may result from an inadequate or inappropriate sampling plan1.

A . Correct Answer:
Independence is compromised when an auditor alters audit findings under pressure.
The audit team leader misrepresented compliance, violating ISO 19011's principles of objectivity and integrity.
B . Incorrect:
Including anonymous evidence in an audit report is acceptable as long as it is verified.
C . Incorrect:
While revealing confidential information would be unethical, it was not mentioned in the scenario.
