Isaca Certification CRISC Release Date

The effectiveness of anti-malware software is the degree to which it can detect, prevent, and remove malicious software (malware) from the system or network. Malware is any software that is designed to harm, exploit, or compromise the functionality, security, or privacy of the system or network1. Some common types of malware are viruses, worms, Trojans, ransomware, spyware, adware, and rootkits2.

One of the best indicators of the effectiveness of anti-malware software is the number of successful attacks by malicious software, which means the number of times that malware has managed to bypass, evade, or disable the anti-malware software and cause damage or disruption to the system or network. The lower the number of successful attacks, the higher the effectiveness of the anti-malware software. This indicator can measure the ability of the anti-malware software to protect the system or network from known and unknown malware threats, and to respond and recover from malware incidents34.

The other options are not the best indicators of the effectiveness of anti-malware software, because:

Number of staff hours lost due to malware attacks is a measure of the impact or consequence of malware attacks on the productivity or performance of the staff. It does not directly reflect the ability of the anti-malware software to detect, prevent, or remove malware, as there may be other factors that affect the staff hours lost, such as the severity of the attack, the availability of backup or recovery systems, or the skills and awareness of the staff5.

Number of downtime hours in business critical servers is a measure of the impact or consequence of malware attacks on the availability or reliability of the servers. It does not directly reflect the ability of the anti-malware software to detect, prevent, or remove malware, as there may be other factors that affect the downtime hours, such as the type of the server, the configuration of the network, or the maintenance of the hardware6.

Number of patches made to anti-malware software is a measure of the maintenance or improvement of the anti-malware software. It does not directly reflect the ability of the anti-malware software to detect, prevent, or remove malware, as there may be other factors that affect the number of patches, such as the frequency of the updates, the quality of the software, or the compatibility of the system7.

The best indicator of the risk appetite and tolerance level for the risk associated with business interruption caused by IT system failures is the recovery time objective (RTO). The RTO is the maximum acceptable time or duration that a business process or an IT system can be disrupted or interrupted before it causes unacceptable impact or harm to the business. The RTO reflects the risk appetite and tolerance level for thebusiness interruption risk, as it indicates how much disruption or interruption the business can tolerate or accept, and how quickly the business needs to resume or recover the business process or the IT system. The RTO also helps to determine the priorities and requirements for the business continuity and recovery planning, and to select and implement the appropriate continuity and recovery strategies and solutions. Mean time to recover (MTTR), IT system criticality classification, and incident management service level agreement (SLA) are not the best indicators of the risk appetite and tolerance level for the business interruption risk, as they are either the measures or the outcomes of the business continuity and recovery performance, and they do not directly indicate how much disruption or interruption the business can tolerate or accept. References = CRISC Review Manual, 6th Edition, ISACA, 2015, page 50

A critical threshold value for a key control indicator (KCI) is the value that indicates that the control is no longer performing its intended function of mitigating a risk. If the KCI reaches or exceeds this value, it means that the control effectiveness has failed and corrective actions are needed. The other options are not the best representations of a critical threshold value for a KCI, because they do not reflect the actual performance or outcome of the control. Thresholds benchmarked to peer organizations, a typical operational value, and a value that represents the intended control state are examples of target or acceptable values for a KCI, not critical or unacceptable values. References = CRISC: Certified in Risk & Information Systems Control Sample Questions

The most important objective of an enterprise risk management (ERM) program is to create a comprehensive view of critical risk to the organization, as it enables the organization to identify, assess, and prioritize the key risks that may affect its objectives and strategy, and to implement appropriate risk responses and controls. A comprehensive view of critical risk also helps the organization to align its risk appetite and tolerance with its business goals and value creation, and to enhance its risk culture and governance. A comprehensive view of critical risk can be achieved by integrating risk management across all levels and functions of the organization, and by using consistent and reliable risk information and reporting. References = ISACA Certified in Risk and Information Systems Control (CRISC) Certification Exam Question and Answers, Question 242. CRISC: Certified in Risk & Information Systems Control Sample Questions, Question 242. CRISC Sample Questions 2024, Question 242.
