该课程主要是为了适应计算机网络安全技术发展和应用的需要，以培养“基础扎实、视野开阔、德才兼备”的信息安全专业人才为总目标，帮助学生树立正确的总体国家安全观和网络安全观，并对新一代的网络安全攻防技术有比较全面的认识。

该课程会从网络协议和各个应用层协议出发，分析其中的漏洞以及相关攻击方式，使学生能够了解网络安全相关的原理，用攻防对抗无限迭代的思维和网络空间全局的视角来探索网络安全世界。教学过程中强调在实际系统的操作中发现问题、分析问题和解决问题，注重各教学环节（理论教学、小班讨论、课程实验、实验课程）的有机联系，特别是强化小班讨论与课程实验环节，使学生加深对课堂教学内容的理解，提高分析解决问题的能力。教学中有计划有目的地向学生介绍各专业课之间的关系，配合实际应用例子，由浅入深善于诱导，使学生从被动吸收知识转化为主动索取知识，培养学生的学习兴趣。

通过该课程的学习，使学生能够了解网络安全相关的原理，从网络协议和各个应用层协议出发，分析其中的漏洞和攻击方式，用全局的视角来探索网络安全世界。同时，通过课程可以帮助学生更好地理解如何检测和防范各种攻击，掌握设计、维护安全的复杂网络架构及网络工程应用系统的基本手段和常用方法，具有追踪最新网络安全问题的意识和能力。

（二）课程英文简介

This course is mainly in order to adapt to the needs of the development and application of computer network security technology, in order to cultivate "solid foundation, broad vision, both integrity and ability" of information professionals as the overall goal, to help students establish a correct concept of network security, and network security technology has a comprehensive understanding and understanding.

This course will start from the network protocol and each application layer protocol, analyze the vulnerabilities and related attack methods, so that students can understand the principles related to network security, with a global perspective to explore the world of network security. Emphasized in the teaching process found problems in the operation of the actual system, to analyze and solve problems, pay attention to each teaching link (theory teaching, small class discussion, course experiment, experiment courses) of organic connection, especially strengthen small class discussion and curriculum experiment link, causes the student to deepen the understanding of classroom teaching content, improve the ability of problem solving. In the teaching, the relationship between the professional courses is introduced to the students in a planned and purposeful way. With practical application examples, the students are good at inducing from the shallow to the deep, so that the students can transform from passive absorption of knowledge to active acquisition of knowledge and cultivate their interest in learning.

Through the study of this course, students can understand the principles related to network security, analyze the vulnerabilities and attack modes from the perspective of network protocols and various application-layer protocols, and explore the world of network security from a global perspective. At the same time, the course can help students better understand how to detect and prevent various attacks, master the basic means and common methods of designing and maintaining a secure complex network architecture and network engineering application system, and have the awareness and ability to track the latest network security problems.
