防御高级持续性威胁（APT）的网络安全策略
摘 要
高级持续性威胁（APT）攻击具有高度隐蔽性和长期潜伏性，对关键信息基础设施和企业网络安全构成严重挑战。本研究旨在构建一套系统化的APT防御策略框架，以应对日益复杂的网络威胁环境。通过分析典型APT攻击案例特征，结合机器学习算法与行为分析技术，提出基于多层次协同检测机制的防御模型。该模型融合了终端检测响应、网络流量分析及威胁情报共享等关键技术，实现了从威胁感知到响应处置的全流程覆盖。实验结果表明，所提出的防御体系能够有效识别并阻断APT攻击链中的关键环节，显著提升网络系统的整体安全性。特别是通过引入自适应学习机制，系统具备了动态调整防护策略的能力，增强了对抗未知威胁的技术优势。

Abstract
Advanced persistent threat (APT) attacks are highly covert and long-term latent, posing serious challenges to critical information infrastructure and enterprise network security. This study aims to construct a systematic fr amework of APT defense strategies to address the increasingly complex cyber threat environment. By analyzing the characteristics of typical APT attack cases, combining machine learning algorithm and behavior analysis technology, a defense model based on multi-level cooperative detection mechanism is proposed. The model integrates key technologies such as terminal detection and response, network traffic analysis and threat intelligence sharing, realizing the coverage of the whole process from threat perception to response and disposal. The experimental results show that the proposed defense system can effectively identify and block the key links in the APT attack chain, and significantly improve the overall security of the network system. Especially through the introduction of adaptive learning mechanism, the system has the ability to dynamically adjust the protection strategy, and enhance the technical advantages against unknown threats.
