To reduce false positive alerts, it is essential to carefully configure a limited set of rules tailored to the organization's specific data loss prevention needs. This ensures that the DLP tool accurately identifies true positives and reduces the occurrence of false alarms.

This means that the IT steering committee is responsible for ensuring that the IT strategy aligns with and supports the business strategy, vision, and goals of the organization. The IT steering committee is also responsible for overseeing and approving major IT initiatives, projects, and investments, and allocating resources and priorities accordingly12.
Developing and assessing the IT security strategy (B) is not the main responsibility of the IT steering committee, but rather a specific aspect of the IT strategy that may be delegated to a subcommittee or a dedicated security function. The IT steering committee may provide guidance and oversight for the IT security strategy, but it is not directly involved in developing and assessing it12.
Implementing processes to integrate security with business objectives is not the main responsibility of the IT steering committee, but rather an operational task that may be performed by the IT management and staff. The IT steering committee may monitor and evaluate the effectiveness of the security processes, but it is not directly involved in implementing them12.
Developing and implementing the secure system development framework (D) is not the main responsibility of the IT steering committee, but rather a technical task that may be performed by the IT developers and engineers. The IT steering committee may approve and endorse the secure system development framework, but it is not directly involved in developing and implementing it12.

The management decision that presents the greatest risk associated with data leakage is not providing security awareness training to staff. This is because staff are often the weakest link in the information security chain, and they may unintentionally or maliciously leak sensitive data through various channels, such as email, social media, cloud storage, or removable media. Security awareness training is essential to educate staff on the importance of protecting data, the policies and procedures for handling data, and the best practices for preventing and reporting data leakage incidents. Not requiring desktops to be encrypted, allowing staff to work remotely, and not updating security policies in the past year are also management decisions that may increase the risk of data leakage, but they are not as significant as not providing security awareness training to staff. Encryption, remote work, and security policies are technical or administrative controls that can be implemented or enforced by management, but they cannot fully prevent or mitigate human errors or malicious actions by staff.

This is because the business processes are the core activities and functions that enable the organization to achieve its objectives and create value for its stakeholders. The business processes are also the sources and drivers of various risks that may affect the organization's performance, compliance, and reputation. Therefore, the IS auditor should focus on understanding, assessing, and prioritizing the business processes that are most critical, complex, or vulnerable to the organization's success, and align the audit objectives, scope, and resources accordingly12.
Critical business applications (A) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather a specific aspect of the business processes that may require attention.
Critical business applications are the software systems that support the execution and automation of the business processes, such as enterprise resource planning (ERP), customer relationship management (CRM), or accounting systems. Critical business applications may pose significant risks to the organization if they are not reliable, secure, or efficient. Therefore, the IS auditor should consider the criticality, functionality, and dependency of the business applications when planning the audit, but not as the primary focus12.
Existing IT controls are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an outcome or output of the risk assessment process. Existing IT controls are the policies, procedures, practices, and technologies that are implemented to manage and mitigate the IT-related risks that may affect the organization's business processes and objectives. Existing IT controls may vary in their design, effectiveness, and maturity. Therefore, the IS auditor should evaluate and test the existing IT controls as part of the audit execution and reporting process, but not as the main focus12.
Recent audit results (D) are not the most important area of focus for an IS auditor when developing a risk-based audit strategy, but rather an input or source of information for the risk assessment process. Recent audit results are the findings, recommendations, and opinions of previous audits that may provide insights or feedback on the organization's business processes, risks, and controls. Recent audit results may also indicate any changes or trends in the organization's risk profile or environment. Therefore, the IS auditor should review and consider the recent audit results as part of the audit planning and scoping process, but not as the main focus12.
