Explanation
Audit evidence should be evaluated against the audit criteria in order to determine audit findings.
* Audit evidence is the information obtained by the auditors during the audit process that is used as a basis for forming an audit opinion or conclusion12. Audit evidence could include records, documents, statements, observations, interviews, or test results12.
* Audit criteria are the set of policies, procedures, standards, regulations, or requirements that are used as a reference against which audit evidence is compared12. Audit criteria could be derived from internal or external sources, such as ISO standards, industry best practices, or legal obligations12.
* Audit findings are the results of a process that evaluates audit evidence and compares it against audit criteria13. Audit findings can show that audit criteria are being met (conformity) or that they are not being met (nonconformity). They can also identify best practices or improvement opportunities13.

Explanation
"In a third-party audit an observation can indicate conformity at organisation is not required to take action." According to the PECB Candidate Handbook1, an observation is "a statement of fact made during an audit and substantiated by objective evidence". An observation can indicate conformity or nonconformity, but it does not require any corrective action from the audited organisation. A recommendation, on the other hand, is "a suggestion for improvement based on an observation". A recommendation may or may not be accepted by the audited organisation.
According to the Fundamentals - Third parties2, a third-party audit is "an audit conducted by an external organisation that has the legal right to audit an organisation's processes and procedures". A third-party audit can result in a finding, which is "a conclusion reached by the auditor based on the audit evidence collected". A finding can be positive or negative, depending on whether the audited organisation meets the audit criteria or not. A nonconformity is "a finding that indicates the non-fulfilment of a requirement". A nonconformity requires corrective action from the audited organisation to prevent recurrence.

Explanation
According to ISO/IEC 27001:2022, clause 8.2.1, the organization shall ensure that access to information and information processing facilities is limited to authorized users based on the access control policy and in accordance with the business requirements of access control2.

The three options that will not be in your audit trail are A, C, and H. These options are either not relevant to the information security of ABC's healthcare mobile app development, support, and lifecycle process, or not within the scope of your audit. The amount of money that residents' family members pay to install the app (A) and the number of users of the app are not related to the information security aspects or objectives of the ISMS1. The verification of the developer's certifications (H) is not your responsibility as an ISMS auditor, as you should rely on the competence and impartiality of the certification bodies that issued them2. The other options are relevant and within the scope of your audit, as they relate to the security functions, testing, policies, and procedures of the mobile app development, support, and lifecycle process13.

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.
