Why is involving HR crucial in insider threat management?

Involving HR in insider threat management is crucial because HR plays a key role in understanding and monitoring employee behavior. They have insights into employee dynamics, grievances, and overall workplace culture, making them well-positioned to identify potential risks that could lead to insider threats. HR professionals are trained to recognize changes in behavior or patterns that may indicate an employee is becoming a risk to the organization.

Moreover, HR can facilitate training and awareness programs that educate employees about security policies and the potential impacts of insider threats, fostering a culture of vigilance. By being proactive in identifying troubling behavior or situations, HR can help mitigate risks before they escalate into actual threats.

The other options do not accurately represent HR's role or the importance of their involvement. For example, HR is not limited to simply ignoring grievances or just focusing on recruitment, nor do they manage IT infrastructure independently. Instead, their holistic approach to employee relations and organizational culture makes them an essential partner in managing insider threats effectively.
