摘要
网络安全技术有:防火墙、入侵检测和漏洞扫描等。防火墙能根据安全策略控制出入网络信息流,且本身具有抗攻击能力。入侵检测技术检测网络或系统是否有违反安全策略的行为和遭到攻击的迹象,监控、分析用户和系统的活动,识别攻击的活动模式,分析异常活动。网络漏洞扫描方法分为:直接测试、推断、认证测试。
The network security includes firewall, intrusion detection and hole scanning etc. The information flow of network is controlled by firewall according to security strategy, and itself has the ability to stand against attack. Intrusion detection can be used to detect if there is action of breaking security strategy and evidence of encounter attack in network or system, and to monitor and analyze activity of user and system. It can identify flow pattern of attack, and analyze abnormal activity. Hole scanning is divided into directly test,concluding and authentication test.
