针对计算机网络安全课程覆盖面广、理论抽象的特点，通过对该课程实践教学的研究，为学生设计了既能较好 地掌握基础理论，又能有效提高实际安全技术水平的实验项目。

Aiming at the features of the course of computer network safety such as wide coverage and abstract theory and through the research on the practical teaching, this thesis designs the experimental items for students which can not only let them master the basic theories better, but also effectively improve practical level of safety technology.
