Introduction: When it comes to cybersecurity, the focus often remains on external threats such as hackers and malware. However, one of the most significant vulnerabilities organizations face is the human element. Insider threats, posed by employees, contractors, or business partners, can result in severe breaches, data theft, and reputational damage. This article explores the complex issue of insider threats, shedding light on the psychological and organizational factors involved and providing insights into strategies for prevention and mitigation.

By understanding the motives behind insider threats, recognizing behavioral indicators, and implementing preventive and detection strategies, organizations can better protect themselves from the risks posed by their own employees. It is through a combination of technology, policies, and a people-centric approach that organizations can minimize the human element in cybersecurity and create a resilient defense against insider threats.
