Answer: Implement strict role-based access controls, frequent security awareness training, and deploy data loss prevention (DLP) tools.
Correct Option: B. Implement strict role-based access controls, frequent security awareness training, and deploy data loss prevention (DLP) tools. Reasoning: This combination of strategies provides a comprehensive approach to mitigating insider threats: - **Role-based access controls**: Restrict access to data and systems based on a user’s role and responsibilities, limiting the potential for unauthorized access. - **Security awareness training**: Educate employees about the risks of insider threats and the importance of data security, reinforcing responsible behavior. - **Data loss prevention (DLP) tools**: Monitor and prevent the unauthorized transfer of sensitive data outside the organization, even if it’s by an insider. Incorrect Options: - **A**: While valuable for detecting and preventing unauthorized access, these strategies might not address the root causes of insider threats, such as malicious intent or lack of awareness. - **C**: These measures can help reduce the risk of external threats but may not be sufficient to prevent insider threats, as malicious insiders can still find ways to compromise data. - **D**: While important, these measures focus primarily on preventing external threats and may not be sufficient to address insider threats effectively.
