网络安全是一项动态、整体的系统工程。网络风险防范由安全的操作系统、应用系统、防病毒、防火墙、入侵检测、网络监控、信息审计、通信加密、灾难恢复、安全扫描等多个安全组件组成。只有实施全方位的风险防范,才能确保网络安全。 Network security is a dynamic, integrated system engineering. Network risk prevention by the safe operating system, application systems, anti-virus, firewall, intrusion detection, network monitoring, information audit, communication encryption, disaster recovery, security scanning and other security components. Only the implementation of a full range of risk prevention, to ensure network security.
