Isaca CRISC Dumps Questions Answers

Updating the risk register to include outcomes from a risk assessment is the greatest benefit because it enables the organization to prioritize and respond to the most significant risks in a timely manner. The risk register is a tool that records and tracks the current status of risks, their likelihood, impact, and response strategies. By updating the risk register with the results of a risk assessment, the organization can ensure that the risk information is accurate, relevant, and actionable. Maintaining evidence of compliance with risk policy, validating the organization’s risk appetite, and helping to mitigate internal and external risk factors are all possible benefits of updating the risk register, but they are not the greatest benefit, as they do not directly support risk-based decision making.

Prioritizing concerns based on frequency of reports is the most efficient approach to analyze the security-related concerns reported by employees, because it helps to identify and focus on the most common or recurring issues that may pose the highest risk or impact to the organization. A security-related concern is a potential or actual problem or threat that may affect the confidentiality, integrity, or availability of the organization’s IT systems or data. A service desk is a function that provides a single point of contact for users to report and resolve their IT-related issues or requests. A workflow is a sequence of steps or tasks that are performed to achieve a specific goal or outcome. A workflow for supporting employee reports of security-related concerns may include capturing, categorizing, prioritizing, assigning, and resolving the concerns. Prioritizing concerns based on frequency of reports is the most efficient approach, as it helps to optimize the use of resources and time, and to reduce the likelihood and severity of security incidents or breaches. Mapping concerns to organizational assets, sorting concerns by likelihood, and aligning concerns to key vendors are all possible approaches to analyze the security-related concerns, but they are not the most efficient approach, as they may require more data collection, analysis, or coordination, and may not reflect the urgency or importance of the concerns.

Warning banners on login screens serve as deterrent controls. Deterrent controls are designed to discourage individuals from attempting unauthorized actions by warning them of potential consequences.

Purpose of Warning Banners

Warning banners provide clear notice to users, both authorized and unauthorized, that their activities may be monitored and that unauthorized access is prohibited.

They serve as a legal disclaimer, which can be crucial in prosecuting unauthorized access attempts.

Effectiveness as a Deterrent Control

The primary function of a warning banner is to deter potential intruders by making them aware of the surveillance and legal implications of unauthorized access.

For authorized users, it reinforces awareness of the organization's security policies and acceptable use agreements.

Comparison with Other Control Types

A. Corrective: These controls are used to correct or restore systems after an incident.

B. Preventive: These controls are designed to prevent security incidents from occurring.

C. Detective: These controls are used to detect and alert about security incidents.

D. Deterrent: These controls are intended to discourage individuals from performing unauthorized activities.
