According to the Operational Risk: Overview, Importance, and Examples article, operational risk is the risk of loss resulting from inadequate or failed internal processes, people, and systems. One of the factors that can increase operational risk is the complexity of IT infrastructure, which refers to the number, variety, and interdependence of IT components, such as hardware, software, networks, and data. A complex IT infrastructure can pose challenges for IT management, such as increased costs, reduced performance, lower reliability, higher vulnerability, and more difficulty in troubleshooting and maintenance. Therefore, minimizing the complexity of IT infrastructure can help reduce IT operational risk, as it can simplify IT operations, improve IT efficiency and effectiveness, enhance IT security and resilience, and facilitate IT innovation and adaptation.

Penetration testing is the best method for assessing control effectiveness against technical vulnerabilities that could be exploited to compromise an information system, as it simulates a real-world attack scenario and evaluates the security posture of the system. Penetration testing is a type of security testing that involves performing authorized and ethical hacking activities on a system to identify and exploit its vulnerabilities and weaknesses. Penetration testing can help to measure and improve the effectiveness and efficiency of the controls implemented to protect the system from unauthorized access, modification, or damage.
The other options are not the best methods for assessing control effectiveness against technical vulnerabilities that could be exploited to compromise an information system. Vulnerability scanning is an automated process that uncovers potential vulnerabilities in systems and software, but it does not provide information on the impact and severity of the vulnerability or how they can be exploited using different exploitation techniques1.
Systems log correlation analysis is a process of examining and analyzing the records of system activities and events, but it does not directly test the controls or simulate the attack scenarios. Monitoring of intrusion detection system (IDS) alerts is a process of tracking and auditing the system or network for any signs of malicious or anomalous activities, but it does not evaluate the control performance or identify the root causes of the vulnerabilities.

is incorrect. Controls are implemented in the latter stage of risk response process. It is not immediate task after the planning of risk response process, as updating of several documents is done first. The purpose of the Plan Risk Responses process is to develop risk responses for those risks with the highest threat to or best opportunity for the project objectives. The Plan Risk Responses process has four outputs: Risk register updates Risk-related contract decisions Project management plan updates Project document updates

A key performance indicator (KPI) is a measurable value that demonstrates how effectively an organization is achieving its objectives. In the context of disaster recovery planning (DRP), a KPI should reflect the ability of the organization to recover its critical business processes and applications within the predefined time frames and service levels. One of the most important KPIs for DRP is the percentage of applications that met the recovery time objective (RTO) during DRP testing. The RTO is the maximum acceptable length of time that a business process or application can be down after a disaster. By measuring the percentage of applications that met the RTO during DRP testing, the organization can evaluate the performance and reliability of its DRP, identify any gaps or weaknesses, and implement corrective actions to improve its readiness and resilience. The other options are not the best KPIs for DRP, as they do not directly measure the effectiveness of the recovery process. The number of users that participated in the DRP testing is a measure of the involvement and awareness of the staff, but not of the outcome of the testing. The number of issues identified during DRP testing is a measure of the quality and completeness of the DRP, but not of the actual recovery time. The percentage of issues resolved as a result of DRP testing is a measure of the improvement and maturity of the DRP, but not of the current recovery capability.

Explanation/Reference:
Explanation:
Preventative controls are the controls that detect the problem before it occurs. They attempt to predict potential problems and make adjustments to prevent those problems to occur in near future. This prediction is being made by monitoring both the system's operations and its inputs.
Incorrect Answers:
A: Deterrent controls are similar to the preventative controls, but they diminish or reverse the attraction of the environment to prevent risk from occurring instead of making adjustments to the environment.
B: Detective controls simply detect and report on the occurrence of a problems. They identify specific symptoms to potential problems.
C: Compensation controls ensure that normal business operations continue by applying appropriate resource.
