Features: This book adheres to the principle of practicality, combining theoretical knowledge with actual technical implementation to strive for being easy to understand, learn, and use. It can serve as a course textbook for higher vocational colleges, undergraduate programs in computer science and related fields, as well as a reference for engineering technicians in fields such as network engineering, network management, and information management. The book comprehensively and systematically introduces the basic concepts, current status, fundamental theories and principles, basic technologies, and implementation methods of computer network security. The main content includes: encryption technologies (including symmetric encryption, asymmetric encryption, and one-way hash functions), digital signature implementation, key management technologies, key network attack technologies, authentication technologies, firewall technologies, intrusion detection technologies, VPN technologies, and other security technologies. It also covers security issues related to the main services provided by the Internet (WWW services, email services, and e-commerce services), the security issues of network operating systems such as Windows NT, Windows 2000, and UNIX, basic knowledge of computer viruses and conventional virus prevention and control methods, the composition of data backup systems, equipment selection, backup methods, and common backup implementation methods, as well as the relevant concepts of network management and network management protocols—such as the Simple Network Management Protocol (SNMP).
