Abstract

Insider threats represent a significant and evolving challenge to organizational security. These threats, originating from individuals within an organization who misuse their authorized access, can result in devastating data breaches, financial losses, and reputational damage. This article provides a comprehensive overview of insider threats, exploring their various forms, including malicious insiders, negligent employees, and compromised accounts. We present data on the prevalence and impact of insider threats across different industries, drawing on recent research and case studies. The article delves into the strategies and tools available for mitigating these risks, covering both preventative and detective measures. Preventative strategies discussed include robust access control policies, least privilege principles, security awareness training, and employee monitoring solutions. Detective measures encompass anomaly detection systems, user and entity behavior analytics, and security information and event management tools. We also examine best practices for incident response and recovery, emphasizing the importance of timely containment and remediation. By adopting a proactive and multi-layered approach, organizations can effectively manage insider threats and safeguard their valuable assets.
