摘 要
随着信息技术的迅猛发展，局域网在企业、机构中的应用日益广泛，数据泄露风险也愈发凸显。本研究旨在构建全面的数据泄露防护体系，以保障局域网环境下的信息安全。针对当前局域网数据泄露防护存在的技术局限性与管理漏洞，通过深入分析现有防护机制，提出一种基于行为分析与智能检测相结合的综合防护策略。该方法融合了流量监测、异常行为识别、访问控制等多维度技术手段，实现了对潜在威胁的实时感知与精准预警。实验结果表明，所提出的防护策略能够有效降低数据泄露风险，在检测准确率方面较传统方法提升约30%，误报率降低25%。此外，本研究创新性地引入了用户行为画像技术，通过对正常操作模式的学习建立动态基线，从而提高对内部人员恶意行为的识别能力。

Abstract
With the rapid development of information technology, the application of LAN in enterprises and institutions has become increasingly extensive, and the risk of data leakage has become more prominent. This study aims to build a comprehensive data leakage protection system to ensure information security in the LAN environment. In view of the technical limitations and management loopholes of the current LAN data leakage protection, a comprehensive protection strategy based on behavior analysis and intelligent detection is proposed through a thorough analysis of the existing protection mechanism. This method integrates multi-dimensional technical means, such as traffic monitoring, abnormal behavior identification and access control, to realize the real-time perception and accurate early warning of potential threats. The experimental results show that the proposed protection strategy can effectively reduce the risk of data leakage, improve the detection accuracy by about 30% compared with the traditional method, and reduce the false alarm rate by 25%. In addition, this study innovatively introduced the user behavior portrait technology, and established a dynamic baseline through the learning of normal operation mode, so as to improve the identification ability of malicious behavior of internal personnel.
