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。

里面记录了本地安全设置里的所有设置，可以看出[Privilege 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。
