The management action that will most likely change the likelihood rating of a risk scenario related to remote network access is implementing multi-factor authentication. Multi-factor authentication is a technique that requires the user to provide two or more pieces of evidence to verify their identity, such as a password, a token, or a biometric factor. Multi-factor authentication can help to reduce the likelihood of unauthorized or malicious access to the remote network, as it adds an extra layer of security and makes it harder for the attackers to compromise the user credentials. The other options are not as likely to change the likelihood rating of the risk scenario, as they are related to the update, creation, or maintenance of the remote network access, not the verification or protection of the remote network access.

According to the CRISC Review Manual (Digital Version), the primary reason a risk practitioner would be interested in an internal audit report is to evaluate the maturity of the risk management process, as it provides an independent and objective assessment of the effectiveness and efficiency of the risk management activities and controls. An internal audit report helps to:
Identify and evaluate the strengths and weaknesses of the risk management process and its alignment with the organization's objectives and strategy Detect and report any gaps, errors, or deficiencies in the risk identification, assessment, response, and monitoring processes and controls Recommend and implement corrective actions or improvement measures to address the issues or findings in the risk management process Communicate and coordinate the audit results and recommendations with the relevant stakeholders, such as the risk owners, the senior management, and the board Enhance the accountability and transparency of the risk management process and its outcomes References = CRISC Review Manual (Digital Version), Chapter 4: IT Risk Monitoring and Reporting, Section 4.2: IT Risk Reporting, pp. 223-2241

A detective control is a type of internal control that seeks to uncover problems in a company's processes once they have occurred. Examples of detective controls include physical inventory checks, reviews of account reports and reconciliations, as well as assessments of current controls1. A periodic access review is a detective control that involves verifying the access rightsand privileges of users to ensure that they are appropriate and authorized. A periodic access review can help to detect any unauthorized or inappropriate access, such as excessive or redundant permissions, segregation of duties violations, or dormant ororphaned accounts23. The other options are not detective controls, but rather preventive controls, which are designed to prevent errors or fraud from occurring in the first place. A limit check is a preventive control that validates the input data against a predefined range or limit, and rejects any data that falls outside the acceptable range4. Access control software is a preventive control that restricts the access to information systems or resources based on the identity, role, or credentials of the user5. Rerun procedures are preventive controls that ensure the accuracy and completeness of data processing by repeating the same process and comparing the results6.

The primary reason for an organization to include an acceptable use banner when users log in is to reduce the likelihood of insider threat, as it informs the users of the policies, rules, and expectations for the use of the organization's IT resources, and deters them from engaging in unauthorized or malicious activities. The other options are not the primary reasons, as they are more related to the detection, prevention, or mitigation of insider threat, respectively, rather than the reduction of the likelihood of insider threat.

A root cause analysis is a process of identifying and understanding the underlying or fundamental causes or factors that contribute to or result in a problem or incident that has occurred or may occur in the organization.
A root cause analysis can provide useful insights and solutions on the origin and nature of the problem or incident, and prevent or reduce its recurrence or impact.
Performing a root cause analysis is the risk practitioner's best recommendation when the number of tickets to rework application code has significantly exceeded the established threshold, because it can help the organization to address the following questions:
Why did the application code require rework?
What were the errors or defects in the application code?
How did the errors or defects affect the functionality or usability of the application?
Who was responsible or accountable for the application code development and testing?
When and how were the errors or defects detected and reported?
What were the costs or consequences of the rework for the organization and its stakeholders?
How can the errors or defects be prevented or minimized in the future?
Performing a root cause analysis can help the organization to improve and optimize the application code quality and performance, and to reduce or eliminate the need for rework. It can also help the organization to align the application code development and testing with the organization's objectives and requirements, and to comply with the organization's policies and standards.
The other options are not the risk practitioner's best recommendations when the number of tickets to rework application code has significantly exceeded the established threshold, because they do not address the main purpose and benefit of performing a root cause analysis, which is to identify and understand the underlying or fundamental causes or factors that contribute to or result in the problem or incident.
Performing a code review is a process of examining and evaluating the application code for its quality, functionality, and security, using the input and feedback from the peers, experts, or tools. Performing a code review can help the organization to identify and resolve the errors or defects in the application code, but it is not the risk practitioner's best recommendation, because it does not indicate why the application code required rework, and how the errors or defects affected the organization and its stakeholders.
Implementing version control software is a process of using a software tool to manage and track the changes and modifications to the application code, and to ensure the consistency and integrity of the application code.
Implementing version control software can help theorganization to control and monitor the application code development and testing, but it is not the risk practitioner's best recommendation, because it does not indicate why the application code required rework, and how the errors or defects affected the organization and its stakeholders.
Implementing training on coding best practices is a process of providing and facilitating the learning and development of the skills and knowledge on the principles, guidelines, and standards for the application code development and testing. Implementing training on coding best practices can help the organization to enhance the competence and performance of the application code developers and testers, but it is not the risk practitioner's best recommendation, because it does not indicate why the application code required rework, and how the errors or defects affected the organization and its stakeholders.
