Which of the following is an example of a preventive measure against insider threats?

Implementing regular security training and awareness programs is an effective preventive measure against insider threats because it actively educates employees about the importance of data security and their role in protecting sensitive information. Regular training sessions reinforce best practices, raise awareness about potential risks, and provide tools for recognizing and reporting suspicious behavior. This proactive approach helps create a culture of security within the organization, enabling staff to understand the implications of their actions and the need for compliance with policies like HIPAA.

The other options do not necessarily contribute to a stronger security posture. Hiring only senior staff may not guarantee trustworthiness or compliance with security policies. Coercing staff into confidentiality agreements might create a sense of distrust rather than fostering an environment of cooperation and security awareness. Operating solely with manual processes could easily lead to human error and does not capitalize on technological solutions that can enhance security measures. Thus, while these alternatives might have some merit, they do not directly address the importance of education and awareness, which are critical in combating insider threats.
