基于漏洞扫描技术的网络安全风险评估.pdf

摘要
摘要
在现代信息社会里，人们享受着互联网带来的信息便利，但也容易受到网络
安全问题的威胁。目前市场上的主流网络安全产品包括：***、防火墙、入
侵检测/防御系统等，以此来保障系统的安全性。本系统将***技术、防火墙
技术、入侵检测/防御技术和防病毒技术定义为网络安全独立元素。重点针对网络
安全***技术，采用打分制的方法，实现对目的主机的网络安全风险评估，
同时通过设计相应的数学模型和软件雏形，来判断系统的安全等级，为提高系统
的安全性提供科学依据。
关键词：***；风险评估；安全等级；打分制

Abstract
Being in modern information society line, People enjoy the information facilitates
that Internet brings about, but they are bothered by the issue of network security
problems. Currently, the mainstream network security products on the market, include
vulnerability scan, firewall, intrusion detection /intrusion prevent system, etc., which
can protect the security of the system. We define vulnerability scanning technology,
firewall technology, intrusion detection/intrusion prevent technology and virus defense
technology as the independent network security element. For an independent element of
network security - vulnerability scanning technology, using the method-a points system
to achieve the host network security risk assessment, designing the mathematical model
and prototype software, and judging the system's security level, providing scientific
basis for the security of the system.
Key Words: Scan leaks; risk assessment; security level; points system
