LEAD-IMPLEMENTER Online Practice Questions and Answers

Correct Answer: B

Explanation: According to ISO/IEC 27001:2022, clause 10.2.2, the organization shall define and apply an information security incident management process that includes the following activities:

reporting information security events and weaknesses; assessing information security events and classifying them as information security incidents;

responding to information security incidents according to their classification; learning from information security incidents, including identifying causes, taking corrective actions and preventive actions, and communicating the results and actions

taken;

collecting evidence, where applicable.

The standard does not specify who should perform these activities, as long as they are done in a consistent and effective manner. Therefore, the organization may choose to conduct forensic investigation internally or by using external

consultants, depending on its needs, resources, and capabilities. However, the organization should ensure that the external consultants are competent, trustworthy, and comply with the organization's policies and procedures.

Management.

Correct Answer: B

Explanation: A demilitarized zone (DMZ) is a network segment that separates the internal network from the external network, such as the internet. A DMZ is designed to provide a layer of protection for the internal network by limiting the

exposure of publicly accessible resources and services to potential attackers. A DMZ is an example of a preventive control, which is a type of security control that aims to prevent or deter cyberattacks from occurring in the first place.

Preventive controls reduce the likelihood of a successful attack by implementing safeguards and countermeasures that make it more difficult or costly for an attacker to exploit vulnerabilities or bypass security mechanisms. Other examples of

preventive controls include encryption, authentication, access control, firewalls, antivirus software, and security awareness training. (From the PECB ISO/IEC 27001 Lead Implementer Course Manual, page 83)

Correct Answer: C

Explanation: According to ISO/IEC 27001:2022, clause 7.5, an organization is required to maintain documented information to support the operation of its processes and to have confidence that the processes are being carried out as planned. This includes documenting the information security policy, the scope of the ISMS, the risk assessment and treatment methodology, the statement of applicability, the risk treatment plan, the information security objectives, and the results of monitoring, measurement, analysis, evaluation, internal audit, and management review. However, the standard does not specify the level of detail or the format of the documented information, as long as it is suitable for the organization's needs and context. Therefore, documenting each security control that is implemented by describing their functions in detail is not a violation of the standard, but it may not be the most efficient or effective way to document the ISMS. Documenting each security control separately may make it harder to review, update, and communicate the documented information, and may also create unnecessary duplication or inconsistency. A better approach would be to document the processes and activities that involve the use of security controls, and to reference the relevant controls from Annex A or other sources. This way, the documented information would be more aligned with the process approach and the Plan-DoCheck-Act cycle that the standard promotes. References: ISO/IEC 27001:2022, Information security, cybersecurity and privacy protection -- Information security management systems -- Requirements, clauses 4.3, 5.2, 6.1, 6.2, 7.5, 8.2, 8.3, 9.1, 9.2, 9.3, and Annex A ISO/IEC 27001:2022 Lead Implementer objectives and content, 4 and 5

Correct Answer: A

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.

Correct Answer: A

Explanation: According to ISO/IEC 27001 : 2022 Lead Implementer, residual risk is the risk remaining after risk treatment. Residual risk should be compared with the acceptable level of risk, which is the level of risk that the organization is willing to tolerate. If the residual risk is below the acceptable level of risk, then the risk can be accepted. If the residual risk is above the acceptable level of risk, then additional risk treatment options should be considered. Therefore, TradeB should evaluate, calculate, and document the value of risk reduction following risk treatment, which is the difference between the initial risk and the residual risk. This will help TradeB to determine whether the risk treatment was effective and whether the residual risk is acceptable or not.

Correct Answer: B

Explanation: According to ISO/IEC 27001:2022, a threat is any incident that could negatively affect the confidentiality, integrity or availability of an asset1. In this scenario, the asset is the information related to HealthGenic's patients, which is stored and processed by the web-based medical software. The software company's modification of some files that comprised sensitive information related to HealthGenic's patients is an incident that could negatively affect the confidentiality and integrity of the asset, as it resulted in incomplete and incorrect medical reports and invaded the patients' privacy. Therefore, this situation represents a threat to HealthGenic.

Correct Answer: A

Explanation: One of the ways to prepare employees for an ISO/IEC 27001 audit is to conduct practice interviews with them. This can help them to familiarize themselves with the audit process, the types of questions they might be asked, and the evidence they need to provide to demonstrate compliance with the standard. Practice interviews can also help employees to identify any gaps or weaknesses in their knowledge or performance, and to address them before the actual audit. Practice interviews can be conducted by internal auditors, managers, or consultants, and should cover the relevant scope, objectives, and criteria of the audit. (From the PECB ISO/IEC 27001 Lead Implementer Course Manual, page 113) References: PECB ISO/IEC 27001 Lead Implementer Course Manual, page 113 PECB ISO/IEC 27001 Lead Implementer Info Kit, page 10 5 Step Plan: How to Prepare for an ISO 27001 Certification Audit

Correct Answer: A

Explanation: According to ISO/IEC 27001:2013, clause 9.1, an organization must monitor, measure, analyze and evaluate its information security performance and effectiveness. This includes determining what needs to be monitored and measured, the methods for doing so, when and by whom the monitoring and measurement shall be performed, when the results shall be analyzed and evaluated, and who shall be responsible for ensuring that the actions arising from the analysis and evaluation are taken 1. SunDee failed to comply with this requirement and did not monitor or measure the performance and effectiveness of its ISMS for the past two years. As a result, the company did not have any objective evidence or indicators to demonstrate the achievement of its information security objectives, the effectiveness of its controls, the satisfaction of its interested parties, or the identification and treatment of its risks. This also meant that the company did not conduct regular management reviews of its ISMS, as required by clause 9.3, which would provide an opportunity for the top management to ensure the continuing suitability, adequacy and effectiveness of the ISMS, and to decide on any changes or improvements needed 1. Just before the recertification audit, the company decided to conduct an internal audit, as required by clause 9.2, which is a systematic, independent and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which the audit criteria are fulfilled 1. However, the company did not have a well-defined audit program, scope, criteria, or methodology, and relied on the written reports of its staff for the past two years. This caused a disruption in the workforce, as most of the staff had to compile their reports for their departments, leaving the Production Department with less than the optimum workforce, which decreased the company's stock. Moreover, the internal audit process was very inconsistent, as the reports were written by different employees with different styles, formats, and levels of detail. The internal audit process also lacked any qualitative measures, such as performance indicators, metrics, or benchmarks, to evaluate the performance and effectiveness of the ISMS. Therefore, the cause of SunDee's workforce disruption was the negligence of performance evaluation and monitoring and measurement procedures, which led to a lack of objective evidence, a poorly planned and executed internal audit, and a decrease in the company's productivity and stock value.

Correct Answer: B

Explanation: According to ISO/IEC 27001, interested parties are those who can affect, be affected by, or perceive themselves to be affected by the organization's information security activities, products, or services. Interested parties can be classified into four categories based on their influence and interest in the ISMS: Positively influenced interested parties: those who benefit from the ISMS and support its implementation and operation Negatively influenced interested parties: those who are adversely affected by the ISMS and oppose its implementation and operation High-interest interested parties: those who have a strong interest in the ISMS and its outcomes, regardless of their influence Low-interest interested parties: those who have a weak interest in the ISMS and its outcomes, regardless of their influence In scenario 5, the HR manager of Operaze belongs to the category of negatively influenced interested parties, because he/she perceives that the ISMS will create more paperwork and documentation for the HR Department, and therefore opposes its implementation and operation. The HR manager does not benefit from the ISMS and does not support its objectives and requirements.

Correct Answer: C

Explanation: An access control software is a type of preventive control that is designed to limit the access to sensitive files and information based on the user's identity, role, or authorization level. An access control software helps to protect the confidentiality, integrity, and availability of the information by preventing unauthorized users from viewing, modifying, or deleting it. An access control software also helps to create an audit trail that records who accessed what information and when, which can be useful for accountability and compliance purposes. The IT Department of a financial institution decided to implement preventive controls to avoid potential security breaches. Therefore, they separated the development, testing, and operating equipment, secured their offices, and used cryptographic keys. However, they are seeking further measures to enhance their security and minimize the risk of security breaches. An access control software would help the IT Department achieve this objective by adding another layer of protection to their sensitive files and information, and ensuring that only authorized personnel can access them.

A breach of integrity occurs when information is modified or destroyed in an unauthorized or unintended manner. In this case, Diana accidently modified the order details of a customer without their permission, which resulted in the customer receiving an incorrect product. This means that the information about the customer's order was not accurate or complete, and therefore, the integrity principle was breached. Availability and confidentiality are two other information security principles, but they were not violated in this case. Availability is the property of being accessible and usable upon demand by an authorized entity, and confidentiality is the property of preventing disclosure of information to unauthorized individuals or systems.
