【摘要】：近年来飞速发展的移动互联网和智能终端,无所不在的影响着人类社会的政治、经济、文化、军事和生活等各个方面。在媒体行业,随着智能终端的普及,逐渐出现了互联网电视、IPTV和OTT应用等新的媒体业务和传播方式,因此基于传统广电网络的媒体业务也越来越多趋向与互联网的融合,甚至有些业务系统已经完全运行在云计算平台之上,各个单位也开始逐步建设自有的媒体云。在这种新的形式下,采用完备的安全审计手段,尤其是建立适合媒体云架构的网络安全审计系统就显得尤为重要。本文根据媒体业务系统自身特点和安全要求,结合媒体行业某单位网络安全审计系统的建设项目,围绕相关技术、系统工作原理和具体实现方法来展开学习研究。主要内容包括： (1)分析媒体行业网络安全审计的特点,明确课题的研究一方面需要基于数据挖掘技术,另一方面也要适应媒体云的业务架构； (2)分别对数据挖掘技术、虚拟化技术和媒体云的进行了阐述,分析和研究了三者与网络安全审计之间的关系； (3)结合媒体行业某单位的网络安全审计系统建设项目,在总体架构设计与实际需求分析的基础上,完成了该系统的设计和实现工作,并对此过程中的主要环节进行了着重描述。本次课题设计实现的网络安全审计系统已经在某媒体单位的实际业务系统中顺利运行。系统建立在虚拟化平台之上,面向多种新媒体业务系统,结合对大量安全事件的分析,做出安全评估,并通过实时监控和报表分析等方式,帮助系统的管理人员迅速掌握系统与网络安全事件的实时情况和发展趋势,并对采取正确的应急措施提供必要辅助。通过安全策略的制定和各个模块功能的实现,在实际IT环境中系统运行稳定,达到了预期的设计目标。
[Abstract]:In recent years, the rapid development of mobile Internet and intelligent terminals, everywhere affects the political, economic, cultural, military and life aspects of human society.In the media industry, with the popularity of intelligent terminals, new media services and communication methods, such as Internet TV and OTT applications, are gradually emerging. Therefore, media services based on traditional radio and television networks tend to converge with the Internet more and more.Even some business systems have been completely run on cloud computing platform, each unit has started to build its own media cloud.In this new form, it is very important to adopt complete security audit methods, especially to establish a network security audit system suitable for media cloud architecture.According to the characteristics and security requirements of the media business system and the construction project of the network security audit system of a certain unit in the media industry, this paper focuses on the related technology, the working principle of the system and the concrete implementation method to carry out the study and research.The main elements include:1) analyzing the characteristics of network security audit in the media industry, making it clear that the research of the subject needs to be based on data mining technology on the one hand, and to adapt to the business structure of the media cloud on the other;2) the data mining technology, virtualization technology and media cloud are expounded, and the relationship between them and network security audit is analyzed and studied.Combined with the network security audit system construction project of a certain unit in the media industry, on the basis of the overall architecture design and actual demand analysis, the design and implementation of the system are completed, and the main links in the process are described emphatically.The network security audit system designed and implemented in this paper has been running smoothly in the practical business system of a media unit.The system is built on the virtualization platform, facing many kinds of new media business systems, combining with the analysis of a large number of security events, making security assessment, and through real-time monitoring and report analysis, etc.To help the system managers quickly grasp the real-time situation and development trend of system and network security incidents, and provide necessary assistance to take correct emergency measures.Through the formulation of security policy and the realization of each module function, the system runs stably in the actual IT environment, and achieves the expected design goal.
