网络系统的安全因素有四个方面,物理因素、技术因素、管理因素、用户因素。常用的网络安全机制有计算机防火墙、入侵检测系统、网络漏洞扫描及系统安全评估、防病毒系统。在实际设计时,可以使用双重防火墙和入侵检测系统的联动,使内部网络和外部网络形成接近物理隔离的方式,数据经过防火墙、入侵检测系统、防病毒系统的监控,识别其安全级别,防止非法访问或者非法用户的侵入,从而获得较高的安全性。
Network system security factors are four aspects, physical factors, technical factors, management factors, user factors. Commonly used network security mechanisms are computer firewalls, intrusion detection systems, network vulnerability scanning and system security assessment, anti-virus system. In the actual design, you can use the dual firewall and intrusion detection system linkage, the internal network and the external network form a close physical isolation, the data through the firewall, intrusion detection system, anti-virus system monitoring, identify the level of security to prevent illegal Access or illegal user intrusion, resulting in higher security.
