网络安全是一项整体的、动态的系统工程,称为“动态安全”。“动态安全”的含义是,网络安全程度是随着时间的变化而发生改变的。在特定的时间内,在一定的安全策略下,网络是安全的,但是随着时间的演化和环境的变化,网络的安全程度也会随之发生改变,因此网络的安全管理和服务必须随着整个网络环境的变化和技术的不断发展,不断调整,网络安全服务必将是一种“动态”的服务。市场需要什么安全服务网络安全是由安全的操作系统、应用系统、防火墙、网络监控、安全扫描、信息审计、通信加密、灾难恢复、网络反病毒等多个安全组件来保证的。一个单独的组件只能完成其中部分的功能。因此,“网络整
Cyber Security is a holistic, dynamic system engineering called “Dynamic Security.” The meaning of “dynamic security” is that the degree of cybersecurity changes over time. In a certain period of time, under a certain security policy, the network is safe, but with the evolution of time and the changes of the environment, the degree of network security will change accordingly. Therefore, the network security management and service must follow the The entire network environment changes and the continuous development of technology, continuous adjustment, network security services will be a “dynamic” service. What security services are required in the market? Network security is guaranteed by a number of security components such as secure operating systems, application systems, firewalls, network monitoring, security scanning, information auditing, communications encryption, disaster recovery, and network anti-virus. A single component can only accomplish some of these functions. Therefore, "the whole network
