* Control effectiveness is the degree to which a control achieves its intended objective and mitigates the risk that it is designed to address. It is measured by comparing the actual performance and outcome of the control with the expected or desired performance and outcome.
* The best method for assessing control effectiveness is continuous monitoring, which is the process of collecting, analyzing, and reporting on the performance and outcome of the controls on an ongoing basis. Continuous monitoring provides timely and accurate information on the status and results of the controls, and enables the identification and correction of any issues or gaps in the control environment.
* Continuous monitoring can be performed using various techniques, such as automated tools, dashboards, indicators, metrics, logs, audits, reviews, etc. Continuous monitoring can also be integrated with the risk management process, and aligned with the organization's objectives and risk appetite.
* The other options are not the best methods for assessing control effectiveness, because they do not provide the same level of timeliness, accuracy, and completeness of information on the performance and outcome of the controls.
* Ad hoc control reporting is the process of collecting, analyzing, and reporting on the performance and outcome of the controls on an irregular or occasional basis. Ad hoc control reporting may be triggered by specific events, requests, or incidents, and it may not cover all the relevant or critical controls. Ad hoc control reporting may not provide sufficient or consistent information on the control effectiveness, and it may not enable the timely and proactive identification and correction of any issues or gaps in the control environment.
* Control self-assessment is the process of allowing the control owners or operators to evaluate and report on the performance and outcome of their own controls. Control self-assessment can provide useful insights and feedback from the control owners or operators, and it can enhance their awareness and accountability for the control effectiveness. However, control self-assessment may not be objective, reliable, or independent, and it may not cover all the relevant or critical controls. Control self-assessment may not provide sufficient or consistent information on the control effectiveness, and it may not enable the timely and proactive identification and correction of any issues or gaps in the control environment.
* Predictive analytics is the process of using statistical techniques and models to analyze historical and current data, and to make predictions or forecasts about future events or outcomes. Predictive analytics can provide useful insights and trends on the potential performance and outcome of the controls, and it can support the decision making and planning for the control effectiveness.
However, predictive analytics may not be accurate, valid, or reliable, and it may not reflect the actual or current performance and outcome of the controls. Predictive analytics may not provide sufficient or consistent information on the control effectiveness, and it may not enable the timely and proactive identification and correction of any issues or gaps in the control environment.

Explanation:
A review of the parameter settings will provide a good basis for comparison of the actual configuration to the security policy and will provide reliable audit evidence documentation.
Incorrect Answers:
A: While interviewing the firewall administrator may provide a good process overview, it does not reliably confirm that the firewall configuration complies with the enterprise's security policy.
B: While procedures may provide a good understanding of how the firewall is supposed to be managed, they do not reliably confirm that the firewall configuration complies with the enterprise's security policy.
C: While reviewing the device's log file for recent attacks may provide indirect evidence about the fact that logging is enabled, it does not reliably confirm that the firewall configuration complies with the enterprise's security policy.
