什么是HIPS?世界HIPS产品大全介绍
什么是HIPS?
Host Intrusion Prevent System 主机入侵防御系统。HIPS是一种能监控你电脑中文件的运行和文件运用了其他的文件以及文件对注册表的修改,并向你报告请求允许的的软件。如果你阻止了,那么它将无法运行或者更改。比如你双击了一个病毒程序,HIPS软件跳出来报告而你阻止了,那么病毒还是没有运行的。引用一句话:”病毒天天变种天天出新,使得杀软可能跟不上病毒的脚步,而HIPS能解决这些问题。”。 HIPS是以后系统[url=http://security.ctocio.com.cn/]安全[/url]发展的一种趋势,只要你有足够的专业水平,你可以只用HIPS而不需杀毒软件。但是HIPS并不能称为防火墙,最多只能叫做系统防火墙,它不能阻止[url=http://networking.ctocio.com.cn/]网络[/url]上其他计算机对你计算机的[url=http://whatis.ctocio.com.cn/searchwhatis/308/7333808.shtml]攻击[/url]行为。
我们个人用的HIPS可以分为[url=http://whatis.ctocio.com.cn/searchwhatis/275/5949275.shtml]3D[/url]: AD(Application Defend)--应用程序防御体系、[url=http://whatis.ctocio.com.cn/searchwhatis/18/6093518.shtml]RD[/url](Registry Defend)注册表防御体系、FD(File Defend)文件防御体系。它通过可定制的规则对本地的运行程序、注册表的读写操作、以及文件读写操作进行判断并允许或禁止。
目前在有些杀软或防火墙中,也含HIPS功能。

1. CLASSICAL 主机入侵防御系统
这些主机入侵防御系统是用于保护家用计算机免受普通的安全威胁,并能抵抗恶意软件威胁:更多手段和(行为分析、黑名单、白名单、完整性检查)或技术(沙盘、虚拟机)被集成到同一产品中来。
大多数安全辅助工具(SecureIT等),
纯粹的虚拟机和虚拟系统产品(VMWare、Virtual [url=http://whatis.ctocio.com.cn/searchwhatis/461/6025961.shtml]PC[/url]等 etc),
启发式分析引擎(Panda TruePrevent),
实时[url=http://storage.ctocio.com.cn/tt-storage-bfrz/]备份[/url]/恢复和回滚软件(Ghost、FirstDefense、DriveVaccine等) +
完整性检查和文件监视软件,
没有在一至低水平上整合注册表、可执行程序和行为阻止的产品([url=http://kareldjag.over-blog.com/article-184115.html][font=Tahoma][color=#000000]http://kareldjag.over-blog.com/article-184115.html[/color][/font][/url]),
专门的任务分析工具(wsyscheck、IceSword、RootkitRevealer、DarkSpy等),
管理员工具(RunSafe等),
带有主机入侵防御特性的防火墙(Outpost、Jetico、Look'n'Stop、Kerio、风云等)。

-数据窃取(...)
除开那些检测和阻止[url=http://whatis.ctocio.com.cn/searchwhatis/226/6093726.shtml]rootkit[/url]的产品,大多数此类产品也被视作终端主机入侵防御系统.
这些产品不如典型的主机入侵防御系统那么必要,但从另一方面说,它能为你的防御体系提供真正的“附加”防御,特别是为那些:
-从事应用软件数据工作的用户(SQL/[url=http://whatis.ctocio.com.cn/searchwhatis/14/6093014.shtml]Oracle[/url]等经常被缓冲区溢出影响),
-进行有风险上网的用户(破解站点、色情网站),
