Which measure would be MOST effective in mitigating insider threats to confidential information?

• A. Role-based access control
• B. Audit trail monitoring
• C. Privacy policy
• D. Defense in depth

Answer: (A)

Role-based access control (RBAC) serves as a critical mechanism for mitigating insider threats to confidential information. This approach works by ensuring that individuals only have access to the information and resources that are necessary for their job functions. By implementing RBAC, organizations can significantly reduce the risk of unauthorized access to sensitive data because access permissions are determined based on user roles within the organization. In scenarios where an insider poses a threat, restricting access to only what is essential for their role minimizes their opportunity to exploit sensitive information. This principle of least privilege is central in safeguarding confidential data from both malicious actions and unintentional mishaps. By controlling who can access what information, organizations enhance their security posture against potential insider threats. While the other options, such as audit trail monitoring, privacy policies, and defense in depth, contribute to an overall security strategy, they do not provide the targeted access control that RBAC offers. Audit trail monitoring is effective for identifying and tracking suspicious activity after it has occurred but does not prevent access in the first place. Privacy policies establish guidelines for handling confidential information, but they rely on compliance and do not restrict user access. Defense in depth adds layers of security but may not specifically address the access issues related to insider threats. Therefore, role-based
