A security log is a record of security-related events or activities that occur in an IT system, network, or application, such as user authentication, access control, firewall activity, or intrusion detection1. Security logscan help to monitor and audit the security posture and performance of the IT environment, and to detect and investigate any security incidents, breaches, or anomalies2.

The integrity of a security log refers to the accuracy and completeness of the log data, and the assurance that the log data has not been modified, deleted, or tampered with by unauthorized or malicious parties3. The integrity of a security log is essential for ensuring the reliability and validity of the log analysis and reporting, and for providing evidence and accountability for security incidents and compliance4.

Among the four options given, the most important factor to the integrity of a security log is the inability to edit. This means that the security log data should be protected from any unauthorized or accidental changes or alterations, such as adding, deleting, or modifying log entries, or changing the log format or timestamps5. The inability to edit can be achieved by implementing various controls and measures, such as:

Applying digital signatures or hashes to the log data to verify its authenticity and integrity

Encrypting the log data to prevent unauthorized access or disclosure

Implementing least privilege access to the log data to restrict who can view, modify, or delete the log data

Using write-once media or devices to store the log data, such as CD-ROMs or WORM drives

Sending the log data to a secure and centralized log server or repository, and using syslog or other protocols to ensure secure and reliable log transmission

Performing regular backups and archiving of the log data to prevent data loss or corruption

The business process owner is the stakeholder who is responsible for the business process that is supported by the IT system, such as the CRM system. The business process owner has the authority and accountability to manage the risk and its response associated with the business process and the IT system. The business process owner should own the risk of customer data leakage caused by insufficient IT security controls for the new system, as it directly affects the performance, functionality, and compliance of the business process. The other options are not the correct answer, as they involve different roles or responsibilities in the risk management process:

The chief information security officer is the senior executive who oversees the enterprise-wide information security program, and provides guidance and direction to the information security managers and practitioners. The chief information security officer may advise or support the business process owner in managing the risk of customer data leakage, but does not own the risk.

The chief risk officer is the senior executive who oversees the enterprise-wide risk management program, and provides guidance and direction to the risk managers and practitioners. The chief risk officer may advise or support the business process owner in managing the risk of customer data leakage, but does not own the risk.

The IT controls manager is the person who designs, implements, and monitors the IT controls that mitigate the IT risks, such as the IT security controls for the new system. The IT controls manager may advise or support the business process owner in managing the risk of customer data leakage, but does not own the risk. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 3, Section 3.1.1.1, pp. 95-96.

The first factor that should be considered when assessing risk associated with the adoption of emerging technologies is the organizational strategy. The organizational strategy defines the vision, mission, goals, and objectives of the enterprise, and provides the direction and guidance for its activities and decisions. The adoption of emerging technologies should be aligned with the organizational strategy, and support its achievement and performance. The organizational strategy also helps to determine the risk appetite and tolerance of the enterprise, and the criteria for evaluating the risks and benefits of the emerging technologies. Cost-benefit analysis, control self-assessment, and business requirements are also important factors to consider when assessing risk associated with the adoption of emerging technologies, but they are not the first factor to consider. References = Risk and Information Systems Control Study Manual, 7th Edition, Chapter 1, Section 1.2.1.1, page 181

 According to the CRISC Review Manual, a list of unencrypted databases which contain sensitive data would be the most important information for assessing the risk impact, because it would help to determine the extent and severity of the potential data breach or loss. The risk impact is the effect or consequence of the risk occurrence on the business objectives and operations. A list of unencrypted databases which contain sensitive data would indicate the scope and magnitude of the risk exposure and the potential damage to the confidentiality, integrity, and availability of the data. The other options are not the most important information for assessing the risk impact, as they are less relevant or less specific than a list of unencrypted databases which contain sensitive data. The number of users who can access sensitive data would indicate the level of access control and the likelihood of unauthorized access, but it would not indicate thetype and value of the data. The reason some databases have not been encrypted would indicate the cause and rationale of the risk, but it would not indicate the effect or consequence of the risk. The cost required to enforce encryption would indicate the feasibility and affordability of the risk response, but it would not indicate the potential loss or harm of the risk. References = CRISC Review Manual, 7th Edition, Chapter 2, Section 2.2.2, page 78.
