日志分析在信息安全领域的应用和研究综述

随着网络攻击和信息泄露事件频繁发生，对网络安全的需求越来越高。各种IT系统规模日益庞大，架构越发复杂，在生产环境中会生成海量的日志数据。日志数据中记录着系统运行状态信息，分析日志数据能够帮助管理员了解系统运行状况，同时也可以帮助管理员进行故障原因检测、系统性能优化和异常预警等。日志分析作为网络安全领域的一项重要技术，可以通过对网络设备和应用程序产生的日志数据进行挖掘和分析，发现潜在的攻击行为和安全漏洞。本文对日志分析在信息安全领域的应用和研究进行了综述，旨在探讨日志分析的研究现状、技术原理和挑战，以及未来的发展方向。

With the frequent occurrence of network attacks and information leakage incidents, the demand for network security is increasing. Various IT systems are becoming larger in scale and more complex in architecture, generating massive amounts of log data in production environments. Log data records system operational status information, and analyzing log data can help administrators understand system operations, detect fault causes, optimize system performance, and provide abnormal warnings. Log analysis, as an important technology in the field of network security, can mine and analyze log data generated by network devices and applications to discover potential attack behaviors and security vulnerabilities. This article provides an overview of the application and research of log analysis in the field of information security, aiming to explore the research status, technical principles, challenges, and future development directions of log analysis.
