Audit methods are the techniques and procedures that auditors use to collect and evaluate audit evidence.
Audit methods can be classified into two categories: those that involve human interaction and those that do not. Human interaction methods are those that require direct or indirect communication with the auditee or other relevant parties, such as interviews, questionnaires, surveys, observations, or walkthroughs. Non-human interaction methods are those that do not require any communication with the auditee or other parties, such as document reviews, data analysis, or remote surveillance.
Some examples of audit methods that do not involve human interaction are:
Performing a review of auditee's procedures in preparation for an audit: This method involves examining the auditee's documented information, such as policies, processes, records, or reports, to verify their adequacy and effectiveness in meeting the audit criteria. The auditor does not need to interact with the auditee or anyone else to perform this method.
Analysing data by remotely accessing the auditee's server: This method involves accessing and processing the auditee's data, such as performance indicators, logs, metrics, or statistics, to verify their accuracy and reliability in meeting the audit criteria. The auditor does not need to interact with the auditee or anyone else to perform this method.

The establishment phase of an ISMS involves defining the scope, context, objectives, and leadership commitment for information security management within an organization. It also involves identifying and assessing the risks and opportunities related to information security and selecting the appropriate controls to treat them. The implementation phase of an ISMS involves executing the plans and actions to achieve the information security objectives and implement the selected controls. It also involves ensuring the availability of resources and competencies for information security management. The operation phase of an ISMS involves monitoring and measuring the performance and effectiveness of the ISMS and reporting on the results. It also involves addressing nonconformities and taking corrective actions to prevent recurrence. The maintenance phase of an ISMS involves reviewing and evaluating the ISMS at planned intervals and identifying opportunities for improvement. It also involves updating the ISMS as necessary to reflect changes in the internal and external context of the organization. Therefore, an ISMS is set up in the following order: establishment, implementation, operation, maintenance. Reference: ISO/IEC 27001:2022, clauses 6-10; ISO/IEC 27000:2022, clause 4.

The worst possible action that an employee may receive for sharing his or her password or access with others is termination, because this is a serious breach of the organization's information security policy and access control policy. Sharing password or access with others may allow unauthorized users to access sensitive or confidential information, or to perform malicious or fraudulent activities on behalf of the employee. The employee should keep his or her password or access confidential and secure, and should not disclose it to anyone under any circumstances.

Explanation
The correct response is A, because grading criteria provide a common basis for the evaluation of nonconformities across the organization. Grading criteria are the rules or standards that define the severity or impact of nonconformities, and help to determine the appropriate corrective actions and follow-up activities.
Grading criteria are important for several reasons, such as:
They ensure consistency and objectivity in the assessment and reporting of nonconformities, and avoid subjective or arbitrary judgments.
They facilitate the communication and understanding of nonconformities among the auditors, the auditees, and the audit clients, and enable the comparison and benchmarking of nonconformities across different processes, functions, or locations.
They support the prioritization and allocation of resources for the resolution of nonconformities, and the monitoring and measurement of the effectiveness of the corrective actions.
They demonstrate the commitment and accountability of the organization to the continual improvement of the ISMS, and the compliance with the ISMS requirements and expectations.

Explanation:
A third-party audit is an independent assessment of an organisation's management system by an external auditor, who is not affiliated with the organisation or its customers. The auditor verifies that the management system meets the requirements of a specific standard, such as ISO 27001, and evaluates its effectiveness and performance. The auditor also identifies any strengths, weaknesses, opportunities, or risks of the management system, and provides recommendations for improvement. The purpose of a third-party audit is to provide an objective and impartial evaluation of the organisation's management system, and to inform a certification decision by a certification body. A certification body is an organisation that grants a certificate of conformity to the organisation, after reviewing the audit report and evidence, and confirming that the management system meets the certification criteria. A certification decision is the outcome of the certification process, which can be positive (granting, maintaining, renewing, or expanding the scope of certification) or negative (suspending, withdrawing, or reducing the scope of certification).
