Role-based access control provides access according to business needs; therefore, it reduces unnecessary- access rights and enforces accountability.
Audit trail monitoring is a detective control, which is 'after the fact.' Privacy policy is not relevant to this risk.
Defense-in-depth primarily focuses on external threats.
Insider threats to confidential information are a major concern for organizations, as they can cause significant damage to the organization's reputation, financial stability, and legal compliance. It is crucial to implement effective measures to mitigate these threats.
Out of the given options, the MOST effective measure against insider threats to confidential information is Role-based access control (RBAC).
RBAC is a security mechanism that restricts system access to authorized users based on their roles and responsibilities within an organization. It enables administrators to assign specific access rights to users based on their job functions and responsibilities, limiting their access to only the data and systems required to perform their job functions. This way, users can only access the data they need to perform their job, and unauthorized access to confidential information is prevented.
Audit trail monitoring and Privacy policy are also important measures to prevent insider threats, but they are not as effective as RBAC.
Audit trail monitoring involves logging and tracking all system activities and events, which can help detect suspicious behavior by users. However, it does not prevent users from accessing confidential information if they have been granted access rights to it.
A privacy policy outlines the organization's policies and procedures for handling confidential information, but it does not prevent authorized users from misusing or mishandling the information.
Defense-in-depth is a security strategy that involves layering different security measures to provide comprehensive protection against threats. However, it does not specifically address insider threats and may not be as effective as RBAC in preventing unauthorized access to confidential information.
In summary, while all of the given options are important in mitigating insider threats, Role-based access control (RBAC) is the MOST effective measure against insider threats to confidential information.
