PECB ISO-IEC-27001-Lead-Auditor - PECB Certified ISO/IEC 27001 2022 Lead Auditor exam

An audit finding is the result of the evaluation of the collected audit evidence against audit criteria.

According to ISO/IEC 27001:2022, which specifies the requirements for establishing, implementing, maintaining and continually improving an information security management system (ISMS), control 5.7 requires an organization to establish and maintain a threat intelligence process to identify and evaluate information security threats that are relevant to its ISMS scope and objectives1. The organization should use internal and external sources of information, such as vulnerability databases, threat feeds, industry reports, etc., to produce threat intelligence that can be used to support risk assessment and treatment, as well as other information security activities1. Therefore, when auditing the organization’s application of control 5.7, an ISMS auditor should verify that these aspects are met in accordance with the audit criteria.

Three options that represent valid audit trails for verifying control 5.7 are:

I will review the organisation’s threat intelligence process and will ensure that this is fully documented: This option is valid because it can provide evidence of how the organization has established and maintained a threat intelligence process that is consistent with its ISMS scope and objectives. It can also verify that the process is documented according to clause 7.5 of ISO/IEC 27001:20221.

I will check that threat intelligence is actively used to protect the confidentiality, integrity and availability of the organisation’s information assets: This option is valid because it can provide evidence of how the organization has used threat intelligence to support its risk assessment and treatment, as well as other information security activities, such as incident response, awareness, or monitoring. It can also verify that the organization has achieved its information security objectives according to clause 6.2 of ISO/IEC 27001:20221.

I will determine whether internal and external sources of information are used in the production of threat intelligence: This option is valid because it can provide evidence of how the organization has used various sources of information, such as vulnerability databases, threat feeds, industry reports, etc., to produce threat intelligence that is relevant and reliable. It can also verify that the organization has complied with the requirement of control 5.7 of ISO/IEC 27001:20221.

The other options are not valid audit trails for verifying control 5.7, as they are not related to the control or its requirements. For example:

I will speak to top management to make sure all staff are aware of the importance of reporting threats: This option is not valid because it does not provide evidence of how the organization has established and maintained a threat intelligence process or used threat intelligence to support its ISMS activities. It may be related to another control or requirement regarding information security awareness or communication, but not specifically to control 5.7.

I will ensure that the task of producing threat intelligence is assigned to the organisation s internal audit team: This option is not valid because it does not provide evidence of how the organization has established and maintained a threat intelligence process or used threat intelligence to support its ISMS activities. It may also contradict the requirement for auditor independence and objectivity, as recommended by ISO 19011:20182, which provides guidelines for auditing management systems.

I will ensure that the organisation’s risk assessment process begins with effective threat intelligence: This option is not valid because it does not provide evidence of how the organization has established and maintained a threat intelligence process or used threat intelligence to support its ISMS activities. It may also imply a prescriptive approach to risk assessment that is not consistent with ISO/IEC 27005:20183, which provides guidelines for information security risk management.

I will review how information relating to information security threats is collected and evaluated to produce threat intelligence: This option is not valid because it does not provide evidence of how the organization has established and maintained a threat intelligence process or used threat intelligence to support its ISMS activities. It may also be too vague or broad to be an effective audit trail, as it does not specify what criteria or methods are used for collecting and evaluating information.

I will ensure that appropriate measures have been introduced to inform top management as to the effectiveness of current threat intelligence arrangements: This option is not valid because it does not provide evidence of how the organization has established and maintained a threat intelligence process or used threat intelligence to support its ISMS activities. It may be related to another control or requirement regarding management review or performance evaluation, but not specifically to control 5.7.

The following are guidelines to protect your password, except for easy recall use the same password for company and personal accounts; do not share passwords with anyone. Using the same password for company and personal accounts is not a guideline to protect your password, as it increases the risk of compromising your password if one of your accounts is hacked or breached. You should use different and unique passwords for each account, and change them regularly. Sharing passwords with anyone is not a guideline to protect your password, as it reduces the security and accountability of your password. You should keep your password confidential and never disclose it to anyone, even if they claim to be authorized or trustworthy. Don’t use the same password for various company system security access is a guideline to protect your password, as it prevents unauthorized access or misuse of your password if one of the systems is compromised or breached. You should use different and complex passwords for each system, and follow the password policies and standards of the organization. Change a temporary password on first log-on is a guideline to protect your password, as it prevents unauthorized access or misuse of your password if the temporary password is intercepted or leaked. You should change the temporary password to a personal and secure password as soon as possible, and avoid using default or predictable passwords. References: : CQI & IRCA ISO 27001:2022 Lead Auditor Course Handbook, page 43. : [ISO/IEC 27001 LEAD AUDITOR - PECB], page 15.

Vehicular incidents are not a type of information security attack. A vehicular incident is an event that involves a vehicle or its driver causing damage or injury to people or property. A vehicular incident may have an impact on information security if it affects the availability or integrity of information or systems that are transported or accessed by vehicles, but it is not an intentional or malicious attack on information security. Legal incidents are a type of information security attack that involve legal actions or disputes that may compromise the confidentiality or integrity of information or systems. Technical vulnerabilities are a type of information security attack that exploit weaknesses or flaws in software or hardware that may compromise the confidentiality, integrity, or availability of information or systems. Privacy incidents are a type of information security attack that involve unauthorized access or disclosure of personal or sensitive information that may compromise the confidentiality or integrity of information or systems. References: : CQI & IRCA ISO 27001:2022 Lead Auditor Course Handbook, page 25. : [ISO/IEC 27001 LEAD AUDITOR - PECB], page 13.

The following are purposes of information security, except increasing business assets. Increasing business assets is not a purpose of information security, as it is not directly related to protecting information and systems from threats and risks. Information security may contribute to increasing business assets by enhancing customer trust, reputation, compliance, and efficiency, but it is not its primary goal. Ensuring business continuity is a purpose of information security, as it aims to prevent or minimize disruptions or losses caused by incidents affecting information and systems. Minimizing business risk is a purpose of information security, as it aims to identify and reduce threats and vulnerabilities that may compromise information and systems. Maximizing return on investment is a purpose of information security, as it aims to optimize the costs and benefits of implementing and maintaining information security controls and measures. References: : CQI & IRCA ISO 27001:2022 Lead Auditor Course Handbook, page 23. : [ISO/IEC 27001 Brochures | PECB], page 4.

Relevant Standard Reference:

ISO 19011:2018 Clause 6.7 (Audit Reporting Best Practices)

Information security is a matter of building and maintaining trust. Trust is the confidence that information and information processing facilities are protected from unauthorized or malicious actions that could compromise their confidentiality, integrity or availability. Trust is essential for establishing and maintaining relationships with customers, partners, suppliers, employees and other stakeholders who rely on the organization’s information and services. Trust is also a key factor for achieving compliance with legal, regulatory and contractual obligations, as well as meeting the organization’s own information security objectives and policies. ISO/IEC 27001:2022 defines information security as “preservation of confidentiality, integrity and availability of information” (see clause 3.28) and states that “the purpose of an information security management system is to provide a framework for managing activities that influence the trustworthiness of information” (see Introduction). References: CQI & IRCA Certified ISO/IEC 27001:2022 Lead Auditor Training Course, ISO/IEC 27001:2022 Information technology — Security techniques — Information security management systems — Requirements, What is Trust?
