针对当前公安院校信息安全体系课程知识点散且缺乏关联、学生参与度不足的问题，提出利用教材、资源库、案例库等资源构建信息安全体系课程知识图谱，并基于课程知识图谱进行教学改革，介绍知识图谱构建及教学改革过程，最后说明教学改革效果。

In response to the problems of scattered and disconnected knowledge and insufficient student participation in the current information security system courses in public security colleges, it is proposed to use resources such as textbooks, resource libraries, and case libraries to construct a knowledge graph of the information security system courses, and conduct research on teaching method reform based on the course knowledge graph. Not only has the systematization, interactivity, and practicality of information security system teaching been improved, but more importantly, students' learning initiative and exploration ability have also been greatly enhanced. The teaching results show that students' final grades and research competition abilities have been significantly improved.
