中文摘要：

在以数字化校园为特征的高等教育信息化发展进程中,传统的安全防御系统难以适应新的发展形势。提出了以主动防御思想为核心的主动安全防御体系,通过实施评估加固、监测分析、应急响应和恢复追踪四个阶段的综合联动进行主动防御。对主动防御体系的各个功能模块进行了分析,然后对主动防御体系在校园网中的典型应用进行了举例说明。结果表明,主动防御体系有效克服了传统的被动防御体系的不足,能显著提高数字化校园的整体安全水平,为教育信息化的顺利开展提供了有力的安全保障。

英文摘要：

In higher education informatization,the traditional active defense system cannot adapt to the new development.A network security of dynamic defense model based on active defense is proposed,the functional modules of the active defense system are analyzed,and some typical applications of active defense system in campus network are illustrated.The result indicates that the active defense system can overcome some shortcomings of traditional passive defense system,which can ensure the safety of digital campus and the security of education informationization.
