开启端口
如果要开启该端口只要先在“启动类型”选择“自动”,单击“确定”按钮,再打开该服务,在“服务状态”中单击“启动”按钮即可启用该端口,最后,单击“确定”按钮即可。
提示:在Windows 98中没有“服务”选项,你可以使用防火墙的规则设置功能来关闭/开启端口。
常见网络端口
21端口
端口说明:21端口主要用于FTP(File Transfer Protocol,文件传输协议)服务,FTP服务主要是为了在两台计算机之间实现文件的上传与下载,一台计算机作为FTP客户端,另一台计算机作为FTP服务器,可以采用匿名(anonymous)登录和授权用户名与密码登录两种方式登录FTP服务器。目前,通过FTP服务来实现文件的传输是互联网上上传、下载文件最主要的方法。另外,还有一个20端口是用于FTP数据传输的默认端口号。
在Windows中可以通过Internet信息服务(IIS)来提供FTP连接和管理,也可以单独安装FTP服务器软件来实现FTP功能,比如常见的FTP Serv-U。
操作建议:因为有的FTP服务器可以通过匿名登录,所以常常会被黑客利用。另外,21端口还会被一些木马利用,比如Blade Runner、FTP Trojan、Doly Trojan、WebEx等等。如果不架设FTP服务器,建议关闭21端口。
23端口
端口说明:23端口主要用于Telnet(远程登录)服务,是Internet上普遍采用的登录和仿真程序。同样需要设置客户端和服务器端,开启Telnet服务的客户端就可以登录远程Telnet服务器,采用授权用户名和密码登录。登录之后,允许用户使用命令提示符窗口进行相应的操作。在Windows中可以在命令提示符窗口中,键入“Telnet”命令来使用Telnet远程登录。
操作建议:利用Telnet服务,黑客可以搜索远程登录Unix的服务,扫描操作系统的类型。而且在Windows 2000中Telnet服务存在多个严重的漏洞,比如提升权限、拒绝服务等,可以让远程服务器崩溃。Telnet服务的23端口也是TTS(Tiny Telnet Server)木马的缺省端口。所以,建议关闭23端口。
25端口
端口说明:25端口为SMTP(Simple Mail Transfer Protocol,简单邮件传输协议)服务器所开放,主要用于发送邮件,如今绝大多数邮件服务器都使用该协议。比如我们在使用电子邮件客户端程序的时候,在创建账户时会要求输入SMTP服务器地址,该服务器地址默认情况下使用的就是25端口 端口漏洞:
1. 利用25端口,黑客可以寻找SMTP服务器,用来转发垃圾邮件。
2. 25端口被很多木马程序所开放,比如Ajan、Antigen、Email Password Sender、ProMail、trojan、Tapiras、Terminator、WinPC、WinSpy等等。拿WinSpy来说,通过开放25端口,可以监视计算机正在运行的所有窗口和模块。
操作建议:如果不是要架设SMTP邮件服务器,可以将该端口关闭。
53端口
端口说明:53端口为DNS(Domain Name Server,域名服务器)服务器所开放,主要用于域名解析,DNS服务在NT系统中使用的最为广泛。通过DNS服务器可以实现域名与IP地址之间的转换,只要记住域名就可以快速访问网站。
端口漏洞:如果开放DNS服务,黑客可以通过分析DNS服务器而直接获取Web服务器等主机的IP地址,再利用53端口突破某些不稳定的防火墙,从而实施攻击。近日,美国一家公司也公布了10个最易遭黑客攻击的漏洞,其中第一位的就是DNS服务器的BIND漏洞。
操作建议:如果当前的计算机不是用于提供域名解析服务,建议关闭该端口。
67、68端口
端口说明:67、68端口分别是为Bootp服务的Bootstrap Protocol Server(引导程序协议服务端)和Bootstrap Protocol Client(引导程序协议客户端)开放的端口。Bootp服务是一种产生于早期Unix的远程启动协议,我们现在经常用到的DHCP服务就是从Bootp服务扩展而来的。通过Bootp服务可以为局域网中的计算机动态分配IP地址,而不需要每个用户去设置静态IP地址。
端口漏洞:如果开放Bootp服务,常常会被黑客利用分配的一个IP地址作为局部路由器通过“中间人”(man-in-middle)方式进行攻击。
操作建议:建议关闭该端口。
端口说明:69端口是为TFTP(Trival File Tranfer Protocol,次要文件传输协议)服务开放的,TFTP是Cisco公司开发的一个简单文件传输协议,类似于FTP。不过与FTP相比,TFTP不具有复杂的交互存取接口和认证控制,该服务适用于不需要复杂交换环境的客户端和服务器之间进行数据传输。
端口漏洞:很多服务器和Bootp服务一起提供TFTP服务,主要用于从系统下载启动代码。可是,因为TFTP服务可以在系统中写入文件,而且黑客还可以
79端口
端口说明:79端口是为Finger服务开放的,主要用于查询远程主机在线用户、操作系统类型以及是否缓冲区溢出等用户的详细信息。比如要显示远程计算机www.abc.com上的user01用户的信息,可以在命令行中键入“finger user01@www.abc.com”即可。
端口漏洞:一般黑客要攻击对方的计算机,都是通过相应的端口扫描工具来获得相关信息,比如使用“流光”就可以利用79端口来扫描远程计算机操作系统版本,获得用户信息,还能探测已知的缓冲区溢出错误。这样,就容易遭遇到黑客的攻击。而且,79端口还被Firehotcker木马作为默认的端口。
操作建议:建议关闭该端口。
80端口
端口说明:80端口是为HTTP(HyperText Transport Protocol,超文本传输协议)开放的,这是上网冲浪使用最多的协议,主要用于在WWW(World Wide Web,万维网)服务上传输信息的协议。我们可以通过HTTP地址加“:80”(即常说的“网址”)来访问网站的,比如http://www.cce.com.cn:80,因为浏览网页服务默认的端口号是80,所以只要输入网址,不用输入“:80”。
端口漏洞:有些木马程序可以利用80端口来攻击计算机的,比如Executor、RingZero等。
操作建议:为了能正常上网冲浪,我们必须开启80端口。
99端口
端口说明:99端口是用于一个名为“Metagram Relay”(亚对策延时)的服务,该服务比较少见,一般是用不到的。
端口漏洞:虽然“Metagram Relay”服务不常用,可是Hidden Port、NCx99等木马程序会利用该端口,比如在Windows 2000中,NCx99可以把cmd.exe程序绑定到99端口,这样用Telnet就可以连接到服务器,随意添加用户、更改权限。
操作建议:建议关闭该端口。
★109、110端口
端口说明:109端口是为POP2(Post Office Protocol Version 2,邮局协议2)服务开放的,110端口是为POP3(邮件协议3)服务开放的,POP2、POP3都是主要用于接收邮件的,目前POP3使用的比较多,许多服务器都同时支持POP2和POP3。客户端可以使用POP3协议来访问服务端的邮件服务,如今ISP的绝大多数邮件服务器都是使用该协议。在使用电子邮件客户端程序的时候,会要求输入POP3服务器地址,默认情况下使用的就是110端口 端口漏洞:POP2、POP3在提供邮件接收服务的同时,也出现了不少的漏洞。单单POP3服务在用户名和密码交换缓冲区溢出的漏洞就不少于20个,比如WebEasyMail POP3 Server合法用户名信息泄露漏洞,通过该漏洞远程攻击者可以验证用户账户的存在。另外,110端口也被ProMail trojan等木马程序所利用,通过110端口可以窃取POP账号用户名和密码。
操作建议:如果是执行邮件服务器,可以打开该端口。
★111端口
端口说明:111端口是SUN公司的RPC(Remote Procedure Call,远程过程调用)服务所开放的端口,主要用于分布式系统中不同计算机的内部进程通信,RPC在多种网络服务中都是很重要的组件。常见的RPC服务有rpc.mountd、NFS、rpc.statd、rpc.csmd、rpc.ttybd、amd等等。在Microsoft的Windows中,同样也有RPC服务。
端口漏洞:SUN RPC有一个比较大漏洞,就是在多个RPC服务时xdr_array函数存在远程缓冲溢出漏洞,通过该漏洞允许攻击者传递超
113端口
端口说明:113端口主要用于Windows的“Authentication Service”(验证服务),一般与网络连接的计算机都运行该服务,主要用于验证TCP连接的用户,通过该服务可以获得连接计算机的信息。在Windows 2000/2003 Server中,还有专门的IAS组件,通过该组件可以方便远程访问中进行身份验证以及策略管理。
端口漏洞:113端口虽然可以方便身份验证,但是也常常被作为FTP、POP、SMTP、IMAP以及IRC等网络服务的记录器,这样会被相应的木马程序所利用,比如基于IRC聊天室控制的木马。另外,113端口还是Invisible Identd Deamon、Kazimas等木马默认开放的端口。
操作建议:除了经常使用WinGate来共享上网外,那么其他的建议关闭该端口。
1755端口
端口说明:1755端口默认情况下用于“Microsoft Media Server”(微软媒体服务器,简称MMS),该协议是由微软发布的流媒体协议,通过MMS协议可以在Internet上实现Windows Media服务器中流媒体文件的传送与播放。这些文件包括.asf、.wmv等,可以使用Windows Media Player等媒体播放软件来实时播放。其中,具体来讲,1755端口又可以分为TCP和UDP的MMS协议,分别是MMST和MMSU,一般采用TCP的MMS协议,即MMST。目前,流媒体和普通下载软件大部分都支持MMS协议。
端口漏洞:目前从微软官方和用户使用MMS协议传输、播放流媒体文件来看,并没有什么特别明显的漏洞,主要一个就是MMS协议与防火墙和NAT(网络地址转换)之间存在的兼容性问题。
操作建议:为了能实时播放、下载到MMS协议的流媒体文件,建议开启该端口。
4000端口
端口说明:4000端口是用于大家经常使用的QQ聊天工具的,再细说就是为QQ客户端开放的端口,QQ服务端使用的端口是8000。通过4000端口,QQ客户端程序可以向QQ服务器发送信息,实现身份验证、消息转发等,QQ用户之间发送的消息默认情况下都是通过该端口传输的。4000和8000端口都不属于TCP协议,而是属于UDP协议。
端口漏洞:因为4000端口属于UDP端口,虽然可以直接传送消息,但是也存在着各种漏洞,比如Worm_Witty.A(维迪)蠕虫病毒就是利用4000端口向随机IP发送病毒,并且伪装成ICQ数据包,造成的后果就是向硬盘中写入随机数据。另外,Trojan.SkyDance特洛伊木马病毒也是利用该端口的。
操作建议:为了用QQ聊天,4000大门敞开也无妨。
5554端口
端口说明:在今年4月30日就报道出现了一种针对微软lsass服务的新蠕虫病毒——震荡波(Worm.Sasser),该病毒可以利用TCP 5554端口开启一个FTP服务,主要被用于病毒的传播。
端口漏洞:在感染“震荡波”病毒后会通过5554端口向其他感染的计算机传送蠕虫病毒,并尝试连接TCP 445端口并发送攻击,中毒的计算机会出现系统反复重启、运行缓慢、无法正常上网等现象,甚至会被黑客利用夺取系统的控制权限。
操作建议:为了防止感染“震荡波”病毒,建议关闭5554端口。
5632端口
端口说明:5632端口是被大家所熟悉的远程控制软件pcAnywhere所开启的端口,分TCP和UDP两种,通过该端口可以实现在本地计算机上控制远程计算机,查看远程计算机屏幕,进行文件传输,实现文件同步传输。在安装了pcAnwhere被控端计算机启动后,pcAnywhere主控端程序会自动扫描该端口。
端口漏洞:通过5632端口主控端计算机可以控制远程计算机,进行各种操作,可能会被不法分子所利用盗取账号,盗取重要数据,进行各种破坏。
操作建议:为了避免通过5632端口进行扫描并远程控制计算机,建议关闭该端口。
8080端口
端口说明:8080端口同80端口,是被用于WWW代理服务的,可以实现网页浏览,经常在访问某个网站或使用代理服务器的时候,会加上“:8080”端口号,比如http://www.cce.com.cn:8080。
端口漏洞:8080端口可以被各种病毒程序所利用,比如Brown Orifice(BrO)特洛伊木马病毒可以利用8080端口完全遥控被感染的计算机。另外,RemoConChubo,RingZero木马也可以利用该端口进行攻击。
操作建议:一般我们是使用80端口进行网页浏览的,为了避免病毒的攻击,我们可以关闭该端口。
WindowsXP中可以被禁用的服务对照表
服务其实是Win2000/XP/2003中一种特殊的应用程序类型,不过它是在后台运行,所以我们在任务管理器看不到它。
安装WinXP后,通常系统会默认启动许多服务,其中有些服务是普通用户根本用不到的,不但占用系统资源,还有可能被黑客所利用。
查看正在启用的服务项目
以WinXP为例,首先你要使用系统管理员账户或以拥有Administrator权限的用户身份登录,然后在“运行”中输入“cmd.exe”打开命令行窗口,再输入“netstart”回车后,就会显示出系统正在运行的服务
为了更详细地查看各项服务的信息,我们可以在“开始→控制面板→管理工具”中双击“服务”,或者直接在“运行”中输入“Services.msc”打开服务设置窗口
关闭、禁止与重新启用服务
服务分为三种启动类型:
1.自动:如果一些无用服务被设置为自动,它就会随机器一起启动,这样会延长系统启动时间。通常与系统有紧密关联的服务才必须设置为自动。
2.手动:只有在需要它的时候,才会被启动。
3.已禁用:表示这种服务将不再启动,即使是在需要它时,也不会被启动,除非修改为上面两种类型。
如果我们要关闭正在运行的服务,只要选中它,然后在右键菜单中选择“停止”即可。但是下次启动机器时,它还可能自动或手动运行。
如果服务项目确实无用,可以选择禁止服务。在右键菜单中选择“属性”,然后在“常规→启动类型”列表中选择“已禁用”,这项服务就会被彻底禁用。
如果以后需要重新起用它,只要在此选择“自动”或“手动”即可;也可以通过命令行“netstart�服务名�”来启动,比如“netstartClipbook”。
必须禁止的服务
1.NetMeetingRemoteDesktopSharing:允许受权的用户通过NetMeeting在网络上互相访问对方。这项服务对大多数个人用户并没有多大用处,况且服务的开启还会带来安全问题,因为上网时该服务会把用户名以明文形式发送到连接它的客户端,黑客的嗅探程序很容易就能探测到这些账户信息。
2.UniversalPlugandPlayDeviceHost:此服务是为通用的即插即用设备提供支持。这项服务存在一个安全漏洞,运行此服务的计算机很容易受到攻击。攻击者只要向某个拥有多台WinXP系统的网络发送一个虚假的UDP包,就可能会造成这些WinXP主机对指定的主机进行攻击(DDoS)。另外如果向该系统1900端口发送一个UDP包,令“Location”域的地址指向另一系统的chargen端口,就有可能使系统陷入一个死循环,消耗掉系统的所有资源(需要安装硬件时需手动开启)。
3.Messenger:俗称信使服务,电脑用户在局域网内可以利用它进行资料交换(传输客户端和服务器之间的NetSend和Alerter服务消息,此服务与WindowsMessenger无关。如果服务停止,Alerter消息不会被传输)。这是一个危险而讨厌的服务,Messenger服务基本上是用在企业的网络管理上,但是垃圾邮件和垃圾广告厂商,也经常利用该服务发布弹出式广告,标题为“信使服务”。而且这项服务有漏洞,MSBlast和Slammer病毒就是用它来进行快速传播的。
4.TerminalServices:允许多位用户连接并控制一台机器,并且在远程计算机上显示桌面和应用程序。如果你不使用WinXP的远程控制功能,可以禁止它。
5.RemoteRegistry:使远程用户能修改此计算机上的注册表设置。注册表可以说是系统的核心内容,一般用户都不建议自行更改,更何况要让别人远程修改,所以这项服务是极其危险的。
6.FastUserSwitchingCompatibility:在多用户下为需要协助的应用程序提供管理。WindowsXP允许在一台电脑上进行多用户之间的快速切换,但是这项功能有个漏洞,当你点击“开始→注销→快速切换”,在传统登录方式下重复输入一个用户名进行登录时,系统会认为是暴力破解,而锁定所有非管理员账户。如果不经常使用,可以禁止该服务。或者在“控制面板→用户账户→更改用户登录或注销方式”中取消“使用快速用户切换”。
7.Telnet:允许远程用户登录到此计算机并运行程序,并支持多种TCP/IPTelnet客户,包括基于UNIX和Windows的计算机。又一个危险的服务,如果启动,远程用户就可以登录、访问本地的程序,甚至可以用它来修改你的ADSLModem等的网络设置。除非你是网络专业人员或电脑不作为服务器使用,否则一定要禁止它。
8.PerformanceLogsAndAlerts:收集本地或远程计算机基于预先配置的日程参数的性能数据,然后将此数据写入日志或触发警报。为了防止被远程计算机搜索数据,坚决禁止它。
9.RemoteDesktopHelpSessionManager:如果此服务被终止,远程协助将不可用。
10.TCP/IPNetBIOSHelper:NetBIOS在Win9X下就经常有人用它来进行攻击,对于不需要文件和打印共享的用户,此项也可以禁用。
可以禁止的服务
以上十项服务是对安全威胁较大的服务,普通用户一定要禁用它。另外还有一些普通用户可以按需求禁止的服务:
1.Alerter:通知所选用户和计算机有关系统管理级警报。如果你未连上局域网且不需要管理警报,则可将其禁止。
2.IndexingService:本地和远程计算机上文件的索引内容和属性,提供文件快速访问。这项服务对个人用户没有多大用处。
3.ApplicationLayerGatewayService:为Internet连接共享和Internet连接防火墙提供第三方协议插件的支持。如果你没有启用Internet连接共享或WindowsXP的内置防火墙,可以禁止该服务。
4.UninterruptiblePowerSupply:管理连接到计算机的不间断电源,没有安装UPS的用户可以禁用。
5.PrintSpooler:将文件加载到内存中以便稍后打印。如果没装打印机,可以禁用。
6.SmartCard:管理计算机对智能卡的读取访问。基本上用不上,可以禁用。
7.SsdpDiscoveryService:启动家庭网络上的upnp设备自动发现。具有upnp的设备还不多,对于我们来说这个服务是没有用的。
8.AutomaticUpdates:自动从WindowsUpdate网络更新补丁。利用WindowsUpdate功能进行升级,速度太慢,建议大家通过多线程下载工具下载补丁到本地硬盘后,再进行升级。
9.Clipbook:启用“剪贴板查看器”储存信息并与远程计算机共享。如果不想与远程计算机进行信息共享,就可以禁止。
10.ImapiCd-burningComService:用Imapi管理CD录制,虽然WinXP中内置了此功能,但是我们大多会选择专业刻录软件,另外如果没有安装刻录机的话,也可以禁止该服务。
11.Workstation:创建和维护到远程服务的客户端网络连接。如果服务停止,这些连接都将不可用。
12.ErrorReportingService:服务和应用程序在非标准环境下运行时,允许错误报告。如果你不是专业人员,这个错误报告对你来说根本没用。
再就是如下几种服务对普通用户而言也没有什么作用,大家可以自己决定取舍,如:RoutingandRemoteAccess、NetLogon、NetworkDDE和NetworkDDEDSDM。
还有:以后不要拿出自己的端口来让别人教你怎么做,会被攻击的啊!!OK?? 参考技术A 25端口为SMTP
80是WWW服务
135 端口用于启动与远程计算机的RPC 连接
443端口即网页浏览端口,主要是用于HTTPS服务.
3xxx的端口是你的QQ端口.你的QQ是老版本..
建议你关闭25 和135 端口
或者只开启80.443端口就可以了.QQ可以指定端口
进行TCP/IP过滤就可以了 参考技术B 都不能关 参考技术C 不用可以关注这些问题,安装个防火墙就ok了
