Abstract

Insider threats and data breaches pose significant challenges to modern organizations, leading to substantial financial, reputational, and operational damage. Traditional Data Loss Prevention (DLP) systems, which rely on static rule-based mechanisms and keyword-based detection, often fail to address the complexities of evolving insider threats. Such systems struggle to detect subtle behavioral anomalies or obfuscated data exfiltration, leading to high false positives and overlooked malicious activities. This paper explores the integration of Behavioral Analytics and Natural Language Processing (NLP) to enhance DLP systems for mitigating insider threats and preventing data breaches. Behavioral analytics leverages User and Entity Behavior Analytics (UEBA) to establish baseline user behaviors and identify anomalies indicative of suspicious activity. Concurrently, NLP enables contextual analysis of unstructured data—emails, chat logs, and documents—through techniques such as semantic analysis, sentiment detection, and entity recognition. The combined approach provides a proactive and context-aware solution to detect "who" is exhibiting abnormal behavior and "what" content is at risk. Through case studies across industries, this research highlights the effectiveness of behavioral analytics and NLP in improving insider threat detection rates, reducing false positives, and enabling real-time monitoring of sensitive data. Key challenges such as privacy concerns, encrypted data analysis, and ethical considerations are discussed, along with future directions for developing more intelligent, adaptive, and privacy-preserving DLP systems. The findings of this study demonstrate that integrating behavioral analytics and NLP significantly enhances the accuracy and efficiency of DLP systems, offering organizations a robust framework to mitigate insider threats and protect critical data assets.
