According to the PECB Candidate Handbook for ISO/IEC 27001 Lead Auditor, the audit reports should be produced by the audit team leader with input from the audit team, as they are responsible for collecting and analysing the audit evidence1. The audit reports should also include or refer to the audit plan, as it provides the basis for the audit objectives, scope, criteria, and methodology2. Furthermore, the audit reports should be produced within an agreed timescale, as it is part of the audit programme management and ensures timely communication of the audit results3. Additionally, the audit reports should always be reviewed by the client, dated, and signed as 'accepted', as it confirms the audit completion and the formal agreement on the audit findings and conclusions4.
The other statements are false because:
* Audit reports should not be sent to the organisation's top management first because their contents could be embarrassing, as this would compromise the audit impartiality and confidentiality5. Audit reports should be distributed according to the audit programme procedures and the audit plan.
* Audit reports should not be assumed suitable for general circulation unless they are specifically marked confidential, as this would violate the audit confidentiality and the protection of personal information.
Audit reports should be treated as confidential documents and only shared with the authorised parties.
* Audit reports should not only evidence nonconformity, as this would limit the audit scope and value.
Audit reports should also evidence conformity, improvement opportunities, good practices, and audit observations.
* Audit reports that are no longer required should not be destroyed as part of the organisation's general waste, as this would pose a risk to the audit confidentiality and the information security. Audit reports
* should be retained, disposed, or destroyed according to the audit programme procedures and the applicable legal requirements.

The Plan-Do-Check-Act (PDCA) cycle is a four-step method for implementing and improving processes, products, or services. The "plan" phase involves establishing the objectives and processes necessary to deliver the desired results. This may include setting SMART goals, identifying resources, defining roles and responsibilities, conducting risk assessments, and developing plans for training, communication, and monitoring.

According to ISO/IEC 27001, the scope of an ISMS must be defined and documented. This documentation should include the boundaries and applicability of the information security management system, which helps in defining what information, locations, and assets are covered under the ISMS.

The four controls from the list that the auditor in training should review are:
*B. How access to source code and development tools are managed: This control requires the organisation to restrict and monitor the access to the source code and development tools that are used to create, modify, or maintain the software applications and systems that process or store the data of external clients. This is important for ensuring the integrity, confidentiality, and availability of the software and the data, as well as for preventing unauthorized changes, errors, or malicious code injection.
*D. How protection against malware is implemented: This control requires the organisation to implement appropriate measures to detect, prevent, and remove malware from the IT systems and devices that process or store the data of external clients. This includes using antivirus software, firewalls, email filtering, web filtering, and other tools to protect against viruses, worms, ransomware, spyware, and other malicious software. This is essential for safeguarding the data and the systems from corruption, theft, or damage caused by malware.
*E. How the organisation evaluates its exposure to technical vulnerabilities: This control requires the organisation to identify and assess the technical vulnerabilities that may affect the IT systems and devices that process or store the data of external clients. This includes using vulnerability scanning tools, penetration testing tools, threat intelligence sources, and other methods to discover and evaluate the weaknesses and gaps in the security of the systems and the devices. This is necessary for prioritizing and implementing the appropriate corrective actions and controls to mitigate the risks posed by the vulnerabilities.
*G. The organisation's arrangements for information deletion: This control requires the organisation to establish and implement policies and procedures for deleting the data of external clients from the IT systems and devices when it is no longer needed or required. This includes defining the criteria and methods for data deletion, such as secure erasure, encryption, or physical destruction. This is important for complying with the contractual obligations and the legal and regulatory requirements regarding the retention and disposal of the data, as well as for protecting the confidentiality and integrity of the data.

According to ISO/IEC 27000:2018, which provides an overview and vocabulary of information security management systems, an information security event is an identified occurrence of a system, service or network state indicating a possible breach of information security policy or failure of safeguards, or a previously unknown situation that may be security relevant1. An information security incident is a single or a series of unwanted or unexpected information security events that have a significant probability of compromising business operations and threatening information security1. Therefore, based on this definition, three examples of information security incidents are:
* A contractor who has not been paid deletes top management ICT accounts: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in loss of access, data, or functionality for the top management.
* An unhappy employee changes payroll records without permission: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in financial fraud, legal liability, or reputational damage for the organization.
* The organisation's marketing data is copied by hackers and sold to a competitor: This is an example of an unwanted or unexpected information security event that has a significant probability of compromising business operations and threatening information security, as it may result in loss of confidentiality, competitive advantage, or customer trust for the organization.
The other options are not examples of information security incidents, but rather information security events that may or may not lead to incidents depending on their impact and severity. For example:
* The organisation's malware protection software prevents a virus: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, as it is prevented by the malware protection software.
* A hard drive is used after its recommended replacement date: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless it fails or causes other problems.
* The organisation receives a phishing email: This is an example of an identified occurrence of a network state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless it is opened or responded to by the recipient.
* An employee fails to clear their desk at the end of their shift: This is an example of an identified occurrence of a service state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless the desk contains sensitive or confidential information that is accessed by unauthorized persons.
* The organisation fails a third-party penetration test: This is an example of an identified occurrence of a system state indicating a possible breach of information security policy or failure of safeguards, but it does not have a significant probability of compromising business operations and threatening information security, unless the penetration test reveals serious vulnerabilities that are exploited by malicious actors.
