Isaca Updated CISM Exam Questions and Answers by anika

 Unannounced testing is the most accurate way to assess the effectiveness of controls, as it simulates a real-world scenario and does not allow the staff to prepare or modify their behavior in advance. Mature change management processes, senior management support, and well-defined security policies are all important factors for establishing and maintaining a strong security posture, but they do not directly measure the performance of controls. References = CISM Review Manual, 16th Edition, page 149.

The business data owner is accountable for data loss in the event of an information security incident at a third-party provider because they are ultimately responsible for the protection and use of their data, regardless of where it is stored or processed. The information security manager is not accountable for data loss at a third-party provider, but rather responsible for implementing and enforcing the security policies and standards that govern the relationship with the provider. The service provider that hosts the data is not accountable for data loss at their site, but rather liable for any breach of contract or service level agreement that may result from such an incident. The incident response team is not accountable for data loss at a third-party provider, but rather responsible for responding to and managing the incident according to the incident response plan.

Any weaknesses identified, even after an unsuccessful attack, should be tracked and reported until they are fully resolved. This ensures accountability, remediation, and prevention of future incidents. Ignoring or delaying action increases exposure to future threats.

“All vulnerabilities must be tracked, assigned for remediation, and closed out following proper documentation and validation.”

— CISM Review Manual 15th Edition, Chapter 4: Incident Management, Section: Remediation and Lessons Learned

ISACA’s guidance in the practice questions clearly recommends formal tracking and resolution of vulnerabilities as the best practice for ongoing security management.

 A single point of administration in network monitoring is a centralized system that allows network administrators to manage and monitor the entire network from one location. A single point of administration can provide several benefits, such as:

Promoting efficiency in control of the environment: A single point of administration can simplify and streamline the network management tasks, such as configuration, troubleshooting, performance optimization, security updates, backup and recovery, etc. It can also reduce the time and cost of network maintenance and administration, as well as improve the consistency and quality of network services.

Reducing unauthorized access to systems: A single point of administration can enhance the network security by implementing centralized authentication, authorization and auditing mechanisms. It can also enforce consistent security policies and standards across the network, and detect and respond to any unauthorized or malicious activities.

Preventing inconsistencies in information in the distributed environment: A single point of administration can ensure the data integrity and availability by synchronizing and replicating the data across the network nodes. It can also provide a unified view of the network status and performance, and facilitate the analysis and reporting of network data.

Allowing administrative staff to make management decisions: A single point of administration can support the decision-making process by providing relevant and timely information and feedback to the network administrators. It can also enable the administrators to implement changes and improvements to the network based on the business needs and objectives.

Therefore, the primary benefit of introducing a single point of administration in network monitoring is that it promotes efficiency in control of the environment, as it simplifies and streamlines the network management tasks and improves the network performance and quality. References = CISM Review Manual, 16th Edition eBook | Digital | English1, Chapter 4: Information Security Program Development and Management, Section 4.3: Information Security Program Resources, Subsection 4.3.1: Information Security Infrastructure and Architecture, Page 205.
