Automated information security controls are controls that are implemented or executed by software or hardware, without human intervention, to protect the confidentiality, integrity, and availability of information and systems1. Examples of automated information security controls include firewalls, antivirus software, encryption, authentication, and logging2. The effectiveness of automated information security controls refers to how well they achieve their intended objectives and outcomes, such as preventing, detecting, or responding to security threats or incidents3. The best way to measure the effectiveness of automated information security controls prior to going live is to test them in a non-production environment, which is an environment that simulates the production environment, but does not contain real or sensitive data or systems4. Testing in a non-production environment allows the organization to verify the proper and consistent configuration, functionality, and performance of the automated information security controls, without affecting the normal operations or risking the exposure of the data or systems5. Testing in a non-production environment also enables the organization to identify and resolve any issues or gaps in the automated information security controls, and to evaluate their compatibility and interoperability with other systems or controls6. Performing a security control review, reviewing the security audit report, and conducting a risk assessment are not the best ways to measure the effectiveness of automated information security controls prior to going live, as they do not provide direct and timely information on the configuration, functionality, and performance of the automated information security controls. Performing a security control review is a process that involves checking and verifying that the organization's security controls are up to date, relevant, and effective7. A security control review can help to identify and address any issues or gaps in the security controls, but it does not show the actual behavior and results of the automated information security controls in a realistic environment. Reviewing the security audit report is a process that involves reading and analyzing the findings and recommendations of an independent examination and evaluation of the organization's security controls8.
A security audit report can help to provide assurance and advice on the adequacy and effectiveness of the security controls, but it does not show the current and dynamic status and performance of the automated information security controls in a changing environment. Conducting a risk assessment is a process that involves identifying, analyzing, and evaluating the risks and their potential impacts on the organization's objectives and performance. A risk assessment can help to anticipate and prepare for the risks that may affect the organization's security, but it does not show the actual impact and outcome of the automated information security controls in a specific scenario.

The greatest concern for an IT risk practitioner when an employee transfers to another department is that unnecessary access permissions have not been removed. Unnecessary access permissions are the access rights or privileges that are no longer needed, relevant, or appropriate for the employee's new role or responsibility.
If these access permissions are not removed, they may pose a significant security risk, as the employee may be able to access, modify, or delete sensitive or critical data and systems that are not related to their current function. This may result in data leakage, fraud, sabotage, or compliance violations. The other options are not as concerning as unnecessary access permissions, as they are related to the organizational, operational, or knowledge aspects of the employee transfer, not the security or risk aspects of the employee transfer.

Monitoring the number of incidents with downtime exceeding the contract threshold is a critical KRI for assessing the effectiveness of infrastructure upgrades aimed at enhancing service availability. This metric directly reflects the provider's ability to meet agreed-upon service levels and helps identify areas requiring further improvement.

The risk register is a document that records the identified risks, their analysis, and their responses. It is a useful tool for monitoring and controlling the risks throughout the project lifecycle. However, the risk register is not a static document and it should be updated regularly to reflect the changes in the risk environment and the project status. Therefore, when reviewing the risk register, a risk practitioner should not only look at the risk ratings, but also the assumptions and the rationale behind them. Different business units may have different perspectives, contexts, and data sources for the same risk scenario, which can result in significant variances in inherent risk. Inherent risk is the risk level before considering the existing controls or responses.
Therefore, the best course of action is to review the assumptions of both risk scenarios to determine whether the variance is reasonable or not. This can help to identify any errors, inconsistencies, or biases in the risk assessment process, and to ensure that the risk register reflects the current and accurate state of the risks.

According to the CRISC exam content outline2, one of the tasks of a risk practitioner is to "report on risk, in line with organizational reporting requirements, to enable decision making and escalation". Therefore, the first thing that the risk practitioner should do after discovering a policy violation is to report the incident to the appropriate authority, such as the IT security manager or the risk management committee. This will ensure that the incident is properly documented, investigated, and resolved, and that any potential impact or consequences are minimized.
The other options are not the first actions that the risk practitioner should take. Planning a security awareness session (B) may be a preventive measure to avoid future incidents, but it does not address the current one.
Assessing the new risk may be part of the risk response process, but it should be done after reporting the incident and gathering more information. Updating the risk register (D) may be a result of the risk assessment and response, but it should not be done before reporting the incident and following the organizational procedures.
