在Windows环境下搭建Snort+BASE入侵检测系统

安装环境

• 操作系统： Windows 7 (service pack 1)
• 所需软件：
  • 虚拟机：VirtualBox
  • 网络数据包截取驱动程序：WinPcap 4.1.3 (WinPcap_4_1_3.exe)
  • Windows版本的Snort安装包：Snort 2.8.6 for Win32 (Snort_2_8_6_Installer.exe)
  • 官方认证Snort规则库：snortrules-snapshot-2860.tar.gz
  • 数据库组件及分析平台：AppServ 8.6.0 (appserv-win32-8.6.0.exe)
  • WEB前端：Basic Analysis and Security Engine 1.4.5 (base-1.4.5.tar.gz)

由于我们建立的是测试环境，所有的组件安装都在一台机器上完成。

安装前的准备

• 安装虚拟机virtualbox，过程比较简单，此处略过。

• 导入虚拟电脑

  
  
  打开virtualbox，点击左上角管理，然后选择导入虚拟电脑

选择需要导入的虚拟电脑文件进行导入

最好重新初始化网卡地址

部署过程

WinPcap安装过程非常简单，此处略过。

Snort的安装和配置

snort软件安装包

点击同意进到下一步

默认就好，点击next

点击Next

默认安装到c盘，此处我们不需要改变，点击Next

安装完成，点击close

提示snort安装成功

安装规则包

安装规则包之前，rules目录是空的

如果出现是否合并文件夹，一律选是

选择是

安装规则包之后的snort根目录结构

用编辑器打开配置文件snort.conf

按图修改，或者拷贝下面内容把相应行覆盖

var RULE_PATH c:\snort\rules
var SO_RULE_PATH c:\snort\so_rules
var PREPROC_RULE_PATH c:\snort\preproc_rules

按图修改，或者拷贝下面内容把相应行覆盖

# path to dynamic preprocessor libraries
dynamicpreprocessor directory c:\snort\lib\snort_dynamicpreprocessor

# path to base preprocessor engine
dynamicengine c:\snort\lib\snort_dynamicengine\sf_engine.dll

按图修改，或者拷贝下面内容把相应行覆盖

preprocessor http_inspect: global iis_unicode_map c:\snort\etc\unicode.map 1252 

按图修改，或者拷贝下面内容把相应行覆盖

output database: alert, mysql, user=snort password=snort dbname=snortdb host=localhost

按图修改，或者拷贝下面内容把相应行覆盖

include $RULE_PATH/snmp.rules
include $RULE_PATH/icmp.rules
include $RULE_PATH/tftp.rules
include $RULE_PATH/scan.rules
include $RULE_PATH/finger.rules
include $RULE_PATH/web-attacks.rules

AppServ安装和配置

AppServ安装包

点Next

点I Agree

默认安装到C盘，不需要改，点Next

全部选上，点Next

点确定

勾上I agree...，然后点Install

安装成功，点close

默认就好，不需要改变，点Next

设置八位数密码，字符集默认就好，点Install

点Finish

如果弹出安全警报，则点允许访问

此时，打开firefox浏览器，在地址栏输入localhost应该能够看到图中信息，如果不能显示图中信息，则表明AppServ安装有问题，或者没有运行Appche服务

在MySql中创建snortdb和snortarc，以及所需数据表

打开cmd，按照截图所示，以root用户连接到mysql，下面命令都是在mysql输入，注意两个source命令后面没有分号

mysql> create database snortdb;

mysql> create database snortarc;

mysql> use snortdb;

mysql> source c:\snort\schemas\create_mysql

mysql> use snortarc;

mysql> source c:\snort\schemas\create_mysql

mysql> grant usage on *.* to "snort"@"localhost" identified by "snort";

mysql> grant select,insert,update,delete,create,alter on snortdb .* to "snort"@"localhost";

mysql> grant select,insert,update,delete,create,alter on snortarc .* to "snort"@"localhost";

mysql> set password for "snort"@"localhost"=password('snort');

在命令行输入以下命令，使snort工作在网络监测系统模式，并在另一台主机用nmap扫描该主机，则可以在base界面看到统计信息，如下图所示。

c:\snort\bin\snort -i1 -dev -c c:\snort\etc\snort.conf -l c:\snort\log

在同网段另一台主机使用nmap扫描该主机

base显示的snort统计信息

如果运行snort出现以下错误，则按图中步骤进行操作：

如果运行snort出现图中所示错误，则按图操作

至此，windows环境下的snort+base入侵检测系统搭建完毕！
