Pass the PECB ISO 27001 ISO-IEC-27001-Lead-Auditor Questions and answers with Dumpstech

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 5.2 requires top management to establish an information security policy that provides the framework for setting information security objectives1. Clause 6.2 requires top management to ensure that the information security objectives are established at relevant functions and levels1. Therefore, when verifying that the information security policy and objectives have been established by top management, an ISMS auditor should review relevant documents and records that demonstrate top management’s involvement and commitment.

To verify that the mobile device policy and objectives are implemented and effective, an ISMS auditor should review relevant documents and records that demonstrate how the policy and objectives are communicated, monitored, measured, analyzed, and evaluated. The auditor should also sample and verify the implementation of the controls that are stated in the policy.

Three options for the audit trail that are relevant to verifying the mobile device policy and objectives are:

Review the internal audit report to make sure the IT department has been audited: This option is relevant because it can provide evidence of how the IT department, which is responsible for managing the mobile devices and their security, has been evaluated for its conformity and effectiveness in implementing the mobile device policy and objectives. The internal audit report can also reveal any nonconformities, corrective actions, or opportunities for improvement related to the mobile device policy and objectives.

Sampling some mobile devices from on-duty medical staff and validate the mobile device information with the asset register: This option is relevant because it can provide evidence of how the mobile devices that are used by the medical staff, who are involved in processing and storing residents’ data, are registered in the asset register and have physical protection enabled. This can verify the implementation and effectiveness of two of the controls that are stated in the mobile device policy.

Review the asset register to make sure all company’s mobile devices are registered: This option is relevant because it can provide evidence of how the company’s mobile devices that are within the ISMS scope are identified and accounted for. This can verify the implementation and effectiveness of one of the controls that are stated in the mobile device policy.

The other options for the audit trail are not relevant to verifying the mobile device policy and objectives, as they are not related to the policy or objectives or their implementation or effectiveness. For example:

Interview the reception personnel to make sure all visitor and employee bags are checked before entering the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding physical security or access control, but not specifically to mobile devices.

Review visitors’ register book to make sure no visitor can have their personal mobile phone in the nursing home: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security awareness or compliance, but not specifically to mobile devices.

Interview the supplier of the devices to make sure they are aware of the ISMS policy: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to another policy or objective regarding information security within supplier relationships, but not specifically to mobile devices.

Interview top management to verify their involvement in establishing the information security policy and the information security objectives: This option is not relevant because it does not provide evidence of how the mobile device policy and objectives are implemented or effective. It may be related to verifying that the information security policy and objectives have been established by top management, but not specifically to mobile devices.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), clause 8.1 requires an organization to plan, implement and control its processes needed to meet ISMS requirements2. This includes determining what needs to be done, how it will be done, who will do it, when it will be done, what resources are required, how performance will be evaluated, etc2. Therefore, if an ISMS auditor conducting a third-party surveillance audit of a telecom’s provider notes that there has been a significant increase in the number of switches failing their initial configuration test and being returned for reprogramming due to a recent ISMS upgrade that reduced access to work instructions, this indicates a nonconformity against clause 8.1 of ISO/IEC 27001:2022. The organization has failed to plan and control its operational processes effectively to ensure information security and quality2. The other options are not correct clauses to raise a nonconformity against based solely on this information. For example, clause 7.5 deals with documented information required by ISMS or determined by an organization as necessary for its effectiveness2, but it does not specify how many copies or formats of work instructions should be available; clause 10.2 deals with nonconformity and corrective action as a response to an identified problem or incident2, but it does not address how to prevent or avoid such problems or incidents in operational processes; clause 7.3 deals with awareness of ISMS policy, objectives, roles and responsibilities among persons doing work under an organization’s control2, but it does not relate to how work instructions are accessed or followed; clause 7.2 deals with competence of persons doing work under an organization’s control that affects its ISMS performance2, but it does not imply that lack of competence is caused by insufficient work instructions; clause 7.4 deals with communication about ISMS among internal and external interested parties2, but it does not cover how operational information is communicated within an organization. References: ISO/IEC 27001:2022 - Information technology – Security techniques – Information security management systems – Requirements

The correct answer is Materiality, because materiality involves evaluating the significance and potential impact of issues identified during an audit, including financial, legal, contractual, and reputational consequences. In auditing, materiality helps determine which matters are important enough to influence audit conclusions or stakeholder decisions.

When defining materiality, auditors consider factors such as the cost of nonconformities, potential regulatory penalties, contractual breaches, and the broader business impact of noncompliance. For an ISO/IEC 27001 audit, this may include assessing whether failures in information security controls could lead to fines under data protection laws, loss of customer trust, or breach of service-level agreements. These considerations help auditors decide where to focus audit effort and how to prioritize findings.

Option B is incorrect because audit risk relates to the risk that auditors may reach incorrect conclusions due to inherent, control, or detection risks. While costs and penalties may influence risk assessment, they are not evaluated specifically when defining audit risk. Option C is incorrect because reasonable assurance refers to the level of confidence an audit can provide, not the evaluation of financial or legal impacts.

ISO 19011 supports the use of materiality concepts to ensure audits focus on issues that matter most to the organization and interested parties. Therefore, evaluating costs and penalties is directly linked to defining materiality.

Comprehensive and Detailed In-Depth Explanation:

ISO/IEC 27001 Clause 5.1 (Leadership and Commitment) defines top management's role in ensuring the effectiveness of the Information Security Management System (ISMS). It requires top management to:

Ensure the availability of resources for the ISMS (Correct Responsibility).

Promote continual improvement of the ISMS (Correct Responsibility).

Direct and support employees to contribute to ISMS effectiveness (Correct Responsibility).

B. Conducting regular internal audits – Incorrect Responsibility:

Internal audits are not a direct responsibility of top management. Instead, Clause 9.2 (Internal Audit) requires audits to be conducted independently of management.

Top management is responsible for ensuring audits are conducted but does not need to conduct them personally.

Thus, top management is responsible for oversight and support but not for conducting internal audits themselves.

Comprehensive and Detailed In-Depth Explanation:

B. Correct Answer: The certification agreement is between the certification body and the organization (Cobt), not the auditor. Therefore, Sarah’s withdrawal does not impact the certification agreement itself.

A. Incorrect: Sarah does not need approval from the certification body to withdraw, as she had not yet signed the certification agreement.

C. Incorrect: The certification agreement is not dependent on a specific auditor; it is an agreement between the organization and the certification body.
