Question 3 Single choice

You are an ISMS auditor conducting a third-party surveillance audit of a telecom's provider. You are in the equipment staging room where network switches are pre-programmed before being despatched to clients.
You note that recently there has been a significant increase in the number of switches failing their initial configuration test and being returned for reprogramming.

You ask the Chief Tester why and she says, 'It's a result of the recent ISMS upgrade'. Before the upgrade each technician had their own hard copy work instructions. Now, the eight members of my team have to share two laptops to access the clients' configuration instructions online. These delays put pressure on the technicians, resulting in more mistakes being made'.

Explanation

Risk analysis is the process by which the nature of the risk is determined along with its probability and impact. Risk analysis involves estimating the likelihood and consequences of potential events or situations that could affect the organization's information security objectives or requirements. Risk analysis could use qualitative or quantitative methods, or a combination of both. Risk management is the process by which a risk is controlled at all stages of its life cycle by means of the application of organisational policies, procedures and practices. Risk management involves establishing the context, identifying, analyzing, evaluating, treating, monitoring, and reviewing the risks that could affect the organization's information security performance or compliance. Risk management aims to ensure that risks are identified and treated in a timely and effective manner, and that opportunities for improvement are exploited. Risk identification is the process by which a risk is recognised and described. Risk identification involves identifying and documenting the sources, causes, events, scenarios, and potential impacts of risks that could affect the organization's information security objectives or requirements. Risk identification could use various techniques, such as brainstorming, interviews, checklists, surveys, or historical data.
Risk evaluation is the process by which the impact and/or probability of a risk is compared against risk criteria to determine if it is tolerable. Risk evaluation involves comparing the results of risk analysis with predefined criteria that reflect the organization's risk appetite, tolerance, or acceptance. Risk evaluation could use various methods, such as ranking, scoring, or matrix. Risk evaluation helps to prioritize and decide on the appropriate risk treatment options. Risk mitigation is the process by which the impact and/or probability of a risk is reduced by means of the application of controls. Risk mitigation involves selecting and implementing measures that are designed to prevent, reduce, transfer, or accept risks that could affect the organization's information security objectives or requirements. Risk mitigation could include various types of controls, such as technical, organizational, legal, or physical. Risk mitigation should be based on a cost-benefit analysis and a residual risk assessment. Risk transfer is the process by which a risk is passed to a third party, for example through obtaining appropriate insurance. Risk transfer involves sharing or shifting some or all of the responsibility or liability for a risk to another party that has more capacity or capability to manage it. Risk transfer could include various methods, such as contracts, agreements, partnerships, outsourcing, or insurance. Risk transfer should not be used as a substitute for effective risk management within the organization.

Question 10 Single choice

You are an ISMS audit team leader preparing to chair a closing meeting following a third-party surveillance audit. You are drafting a closing meeting agenda setting out the topics you wish to discuss with your auditee.

Which one of the following would be appropriate for inclusion?

  1. A

    A detailed explanation of the certification body's complaints process

  2. B

    An explanation of the audit plan and its purpose

  3. C

    A disclaimer that the result of the audit is based on the sampling of evidence

  4. D

    Names of auditees associated with nonconformities

Show answer and explanation

Correct answer: C

Explanation

This option is appropriate for inclusion in the closing meeting agenda, as it is a requirement of the ISO 19011 standard, which provides guidelines for auditing management systems, including ISMS12. The standard states that the audit team leader should advise the auditee of any situations encountered during the audit that may decrease the confidence that can be placed in the audit conclusions, such as limitations in the audit scope, access, or sampling 3. The standard also states that the audit report should include a statement that the audit is based on a sample of the information available at the time of the audit, and that the audit does not provide absolute assurance of the conformity or effectiveness of the audited management system 4. Therefore, the audit team leader should include a disclaimer in the closing meeting agenda to inform the auditee of the nature and limitations of the audit, and to avoid any misunderstandings or false expectations. The other options are not appropriate for inclusion in the closing meeting agenda, as they are either irrelevant, incorrect, or incomplete. For example:

A detailed explanation of the certification body's complaints process is not relevant for the closing meeting agenda, as it is not related to the audit findings or conclusions. The certification body's complaints process should be communicated to the auditee before the audit, as part of the audit agreement or contract 5.

An explanation of the audit plan and its purpose is not correct for the closing meeting agenda, as it should have been done at the opening meeting or before the audit. The audit plan is a document that describes the scope, objectives, criteria, and methodology of the audit, as well as the audit schedule, the audit team, the audit locations, and the audit deliverables . The audit plan should be communicated and agreed with the auditee in advance, and any changes or deviations should be notified during the audit.

Names of auditees associated with nonconformities are not complete for the closing meeting agenda, as they do not provide the details or the evidence of the nonconformities. The audit team leader should present the audit findings, which include the description, the audit criteria, and the audit evidence of each nonconformity, as well as the audit conclusions and the audit recommendation . The audit team leader should also avoid naming or blaming individuals, and focus on the processes and the system.
