命令行模式改变本地安全策略
命令行模式改变本地安全策略：
前几天在X小组的论坛上逛，看到有人出过一道题目，是这样的：*********************************************************题目：本地安全设置里设置为不允许任何人从本地登陆有输入法漏洞可以物理的使用电脑，但机箱打不开，光驱软驱不能用不知道计算机里面有多少帐号局域网没有主域控制器，要求：拿到最高权并从本地登陆到计算机**********************************************************关于这个问题，我首先是想到的是更改本地安全策略。改注册表，于是开了regsnap观察，拷，修改的项目太多了。根本没法改。还有一种办法，利用secedit.exe这个工具，2k自带的，位于\winnt\system32下面。在命令提示符下打secedit，看一下帮助文件吧。不错很详细：secedit /export [导出安全性设置]secedit /configure [配置安全性设置].........用法还有很多，我们这里只谈这两个。语法secedit /export [/mergedPolicy] [/DB filename ] [/CFG filename ] [/areas area1 area 2...] [/log logPath] [/verbose] [/quiet]语法secedit /configure [/DB filename ] [/CFG filename ] [/overwrite][/areas area1 area2...] [/log logpath] [/verbose] [/quiet]先来解决上面那道题。它说有输入法漏洞，这就好办了，先建立一个快捷方式->属性->目标，在里面写：c:\winnt\system32\secedit.exe /configure /DB c:\winnt\security\database\secedit.sdb /CFG "c:\winnt\security\templates\setup security.inf"(此处我们设它的系统目录为C:)OK!现在运行刚才建立的那个快捷方式，本地安全策略已经改为系统初装时的设定。这道题就算是解了。我们现在再来看看刚才做了些什么。secedit首先调用secedit.sdb引擎数据库，然后将setup security.inf策略模板格式化，再将其导入。setup security.inf这个策略模板是在系统初装时生成的本地安全设置模板。将"c:\winnt\security\templates\setup security.inf"加上引号是因为setup security.inf文件名中包含空格。/DB c:\winnt\security\database\secedit.sdb 这个一定不能少，否则会导入不成功。我们再来看看，在命令提示符下输入：secedit /export /DB c:\winnt\security\database\secedit.sdb /CFG c:\temp\security.inf我们打开来看看这个security.inf。[Version]signature="$CHICAGO$"Revision=1[Profile

Rights]这一组就是本地策略里的用户权利指派，下面是一些与用户登陆有关的项：sedenyinteractivelogonright 拒绝从本地登陆sedenynetworklogonright 拒绝从网络访问这台计算机sedenyservicelogonright 拒绝作为服务登陆sedenybatchlogonright 拒绝作为批处理作业登陆seinteractivelogonright 在本地登陆senetworklogonright 从网络访问此计算机seservicelogonright 作为服务登陆sebatchlogonright 作为批处理作业登陆每一项后面的值是用户或用户组的SID号，每个用户的SID号用逗号隔开，要知道用户的SID号可以用getsid.exe这个工具。注意，拒绝的优先级最高。以前总是有人发现，得到了一个用户的密码，想登陆上去却发现此用户不允许交互式登陆。现在就可以用此方法来更改安全策略，至于怎么改就不在本文的讨论范围了。
