The basic courses of computer network security universities are mainly mathematics and computer knowledge, and the specific courses vary from university to university. The core courses will cover the following directions: discrete mathematics, signal and system, communication principle, software engineering, coding theory, introduction to information security, information theory, data structure, operating system, information system engineering, modern cryptography, network security, information camouflage and so on.

The main courses include: computer principle, computer architecture, computer network, operating system principle, data structure, C language programming, assembly language programming, network programming, distributed system, introduction to computer security, coding theory and application;

At the same time, there are attack methods, security program design, application of cryptographic technology, computer and network security, fault-tolerant system, information system security, database security, computer forensics, and e-commerce security.

Employment orientation: I am engaged in the research, design, development and management of computer security systems in computer network companies, software companies, scientific research departments, educational institutions, administrative departments and modern enterprises.

Can also be engaged in daily network management and maintenance in the IT field, website design and development, network database application and maintenance, or information security product sales and services. Computer network security includes not only the network hardware and software for managing and controlling the network, but also the resources enjoyed by * * * and fast network services, so the definition of network security should cover all the contents involved in computer networks. Referring to the definition of computer security given by ISO, it is considered that computer network security refers to "protecting the hardware, software and data resources in the computer network system from being destroyed, changed or leaked due to accidents or malicious reasons, so that the network system can run continuously and reliably, and the network service can be carried out normally and orderly." Students in this major should not only learn the necessary basic knowledge of mathematics and computer, but also master the professional skills training of computer network technology and network communication, network technology application, network system management, hacker defense and attack, network intrusion prevention system and so on. The computer network technology, network system management, network security technology and other professional courses are organically combined with networking, network construction, network programming, network testing and other corresponding training links, so that students have strong professional skills and quality.
