网络安全(cybersecurity)主要包括2个研究主题,一个是网络自身的安全问题,另一个是网络中传输和存储的信息安全问题。网络自身的安全是指网络环境中相互连接的计算设备、运行维护人员、网络设施、应用程序、服务程序和通信系统等各个网络组成部分的安全。网络信息安全是指保证网络环境中传输、存储的信息在保密性、安全性和可用性等方面不被破坏。网络安全涉及安全工具、策略、概念、指南、防护、技术等多个主题,还涉及安全风险管理过程的中理论方法、管理活动、人员培训、最佳实践、安全保障等不同范畴。网络安全的基本目标是可用性、完
Cybersecurity mainly includes two research topics, one is the network’s own security issues, and the other is the information security issues transmitted and stored in the network. The security of the network itself refers to the security of interconnected computing devices, operation and maintenance personnel, network facilities, applications, service programs and communication systems and other network components in the network environment. Network information security refers to ensuring that the information transmitted and stored in the network environment is not destroyed in terms of confidentiality, security and usability. Cybersecurity involves many topics such as security tools, strategies, concepts, guidelines, protection, technologies and other aspects of the security risk management process, including theoretical approaches, management activities, personnel training, best practices, and safety assurance. The basic goal of cybersecurity is availability, end
