Linux 9系统下构建小型入侵检测系统

发布时间:2005-10-12 00:34:55来源:红联作者:Mrlinux
一、系统平台

  Redhat9.0发行版, 安装gcc 及相关库文件,建议不要安装Apache,PHP,MySQL,我们将用源码编译安装。基于安全方面的考虑,可以设置一下iptables只允许SSH和WWW访问。

  二、软件

  MySQL4.0.12 http://mysql.secsup.org

  Snort2.0.0 http://www.snort.org

  Apache2.0.45 http://www.apache.org
PHP4.3.1 http://www.php.net

  ADODBv3.30 http://phplens.com

  Acid0.9.6b23 http://acidlab.sourceforge.net

  Zlib1.1.4 http://flow.dl.sourceforge.net

  JPGraph1.11 http://jpgraph.techuk.com

  LibPcap0.7.2 http://www.tcpdump.org

  建议到这个站点下载http://ftp.cdut.edu.cn/pub/linux/NEW/

  也可以到http://www.rpmfind.com下载相关的xx.src.rpm编译安装。如若安装了rpm包,可以强行将其反安装rpm -e -nodeps xx.xx

    五.安装配置Web接口

      安装JPGraph1.11

      cp jpgraph-1.11.tar.gz /www/htdocs

      cd /www/htdocs

      tar -xzvf jpgraph-1.xx.tar.gz

      rm -rf jpgrap-1.xx.tar.gz

      cd jpgraph-1.11

      rm -rf README

      rm -rf QPL.txt

      安装ADODB:

      cp adodb330.tgz /www/htdocs/

      cd /www/htdocs

      tar -xzvf adodb330.tgz

      rm -rf adodb330.tgz

      安装配置Acid:

      cp acid-0.0.6b23.tar.gz /www/htdocs

      cd /www/htdocs

      tar -xvzf acid-0.9.6b23.tar.gz

      rm -rf acid-0.9.6b23.tar.gz

      cd /www/htodcs/acid/

      编辑acid_conf.php,修改相关配置如下:

      #8194;$DBlib_path = "/www/htdocs/adodb";

      /* The type of underlying alert database

      *

      * MySQL : "mysql"

      * PostgresSQL : "postgres"

      * MS SQL Server : "mssql"

      */

      #8194;$DBtype = "mysql";

      /* Alert DB connection parameters

      * - ?$alert_dbname : MySQL database name of Snort alert DB

      * - ?$alert_host : host on which the DB is stored

      * - ?$alert_port : port on which to access the DB

      * - ?$alert_user : login to the database with this user

      * - ?$alert_password : password of the DB user

      *

      * This information can be gleaned from the Snort database

      * output plugin configuration.

      */

      #8194;$alert_dbname = "snort";

      #8194;$alert_host = "localhost";

      #8194;$alert_port = "";

      #8194;$alert_user = "root";

      #8194;$alert_password = "Your_Password";

      /* Archive DB connection parameters */

      #8194;$archive_dbname = "snort";

      #8194;$archive_host = "localhost";

      #8194;$archive_port = "";

      #8194;$archive_user = "root";

      #8194;$archive_password = "Your_Password ";

      And a little further down

      #8194;$ChartLib_path = "/www/htdocs/jpgraph-1.11/src";

      /* File format of charts ('png', 'jpeg', 'gif') */

      #8194;$chart_file_format = "png";

      进入web界面:

      http://yourhost/acid/acid_main.php

      点"Setup Page"链接 ->Create Acid AG

      访问http://yourhost/acid将会看到ACID界面。

      六.测试系统

      重启系统或者直接启动相关后台程序:

      /etc/init.d/mysql restart

      /etc/init.d/snort start

      /etc/init.d/httpd start

      利用nmap,nessus,CIS或者X-scan对系统进行扫描,产生告警纪录。

      http://yourhost/acid 察看纪录。

      至此,一个功能强大的IDS配置完毕。各位可以利用web界面远程登陆,监控主机所处局域网,同时安装phpMyAdmin对mysql数据库进行操控。

    四.在mysql中建立数据库

      /usr/local/mysql/bin/mysql

      mysql>SET PASSWORD FOR root@localhost=PASSWORD('your_password');

      mysql>create database snort;

      mysql>grant INSERT,SELECT on root.* to snort@localhost;

      mysql>quit;

      进入snort安装目录:/usr/local/mysql/bin/mysql -p

      gt;Enter password:

      安装DB表:(在contrib目录)

      zcat snortdb-extra.gz | /usr/local/mysql/bin/mysql -p snort

      进入mysql数据库,看看snort数据库中的表:

      /usr/local/mysql/bin/mysql -p

      gt;Enter password:

      mysql>show databases;

      +------------+

      | Database

      +------------+

      | mysql

      | snort

      | test

      +------------+

      3 rows in set (0.00 sec)

      mysql>use snort;

      mysql>show tables; 将会有这些:

      +------------------+

      | Tables_in_snort |

      +------------------+

      | data

      | detail

      | encoding

      | event

      | flags

      | icmphdr

      | iphdr

      | opt

      | protocols

      | reference

      | reference_system

      | schema

      | sensor

      | services

      | sig_class

      | sig_reference

      | signature

      | tcphdr

      | udphdr

      +------------------+

      19 rows in set (0.00 sec)

      mysql>exit

  3. Mrlinux 于 2005-10-12 00:35:37发表:

    httpd.conf中相关内容如下:

      #

      # LoadModule foo_module modules/mod_foo.so

      LoadModule php4_module modules/libphp4.so

      # AddType allows you to tweak mime.types without actually editing it, or ?$

      # make certain files to be certain types.

      #

      AddType application/x-tar .tgz

      AddType image/x- icon .ico

      AddType application/x-httpd-php .php

      设置Apache为自启动:

      cp /www/bin/apachectl /etc/init.d/httpd

      cd /etc/rc3.d

      ln -s /etc/init.d/httpd S85httpd

      ln -s /etc/init.d/httpd K85httpd

      cd /etc/rc5.d

      ln -s /etc/init.d/httpd S85httpd

      ln -s /etc/init.d/httpd K85httpd

      测试一下 PHP:

      cd /etc/init.d

      /httpd start

      在/www/htdocs下建立文件 test.php

      cd /www/htdocs

      vi test.php

      加入

      lt;?php

      hpinfo();

      ?>

      用浏览器访问http://IP_address/test.php,成功的话,出现一些

      系统,apache,php信息

      5.安装 Snort2.0

      5.1建立snort配置文件和日志目录

      mkdir /etc/snort

      mkdir /var/log/snort

      tar -zxvf snort-2.x.x.tar.gz

      cd snort-2.x.x

      /configure --with-mysql=/usr/local/mysql

      make

      make install

      5.2安装规则和配置文件

      cd rules (在snort安装目录下)

      cp * /etc/snort

      cd ./etc

      cp snort.conf /etc/snort

      cp *.config /etc/snort

      5.3修改snort.conf(/etc/snort/snort.conf)

      var HOME_NET 10.2.2.0/24 (修改为你的内部网网络地址,我的是

      192.168.0.0/24)

      var RULE_PATH ./rules 修改为 var RULE_PATH /etc/snort/

      改变记录日志数据库:

      output database: log, mysql, user=root password=your_password

      dbname=snort host=localhost

      5.4设置snort为自启动:

      在snort安装目录下

      cd /contrib

      cp S99snort /etc/init.d/snort

      vi /etc/init.d/snort

      修改snort如下:

      CONFIG=/etc/snort/snort.conf

      #SNORT_GID=nogroup (注释掉)

      #8194;$SNORT_PATH/snort -c ?$CONFIG -i ?$IFACE ?$OPTIONS

      (去掉原文件中的 -g ?$SNORT_GID )

      chmod 755 /etc/init.d/snort

      cd /etc/rc3.d

      ln -s /etc/init.d/snort S99snort

      ln -s /etc/init.d/snort K99snort

      cd /etc/rc5.d

      ln -s /etc/init.d/snort S99snort

      ln -s /etc/init.d/snort K99snort

    三、安装(建议将所有的包文件考到同一目录)

      1.安装zlib1.1.4

      tar -xzvf zlib-xx.tar.gz

      cd zlib-xx

      /configure;make test

      make install

      cd ..

      2.安装LibPcap0.7.2

      tar -xzvf libpcap.tar.gz

      cd libpcap-xx

      /configure

      make

      make install

      cd ..

      3.安装MySQL4.0.12

      3.1创建mysql组和mysql用户

      groupadd mysql

      useradd -g mysql mysql

      修改/root下的.bash_profile的这一行:

      PATH=?$PATH:?$HOME/bin 为

      PATH=?$PATH:?$HOME/bin:/usr/local/mysql/bin

      3.2安装mysql

      tar -xzvf mysql-xx.tar.gz

      cd mysql-xx

      /configure --prefix=/usr/local/mysql

      make

      make install

      cd scripts

      /mysql_install_db

      chown -R root /usr/local/mysql

      chown -R mysql /usr/local/mysql/var

      chgrp -R mysql /usr/local/mysql

      cd ./support-files/my-medium.cnf /etc/my.cnf

      向/etc/ld.so.conf中加入两行:/usr/local/mysql/lib/mysql

      /usr/local/lib

      载入库,执行

      ldconfig -v

      3.3测试mysql是否工作:

      cd /usr/local/mysql/bin/

      /mysqld_safe --user=mysql&

      #ps -ef |grep mysql

      看mysql_safe是否工作

      3.4设置mysql为自启动:

      将mysql安装目录下的support-files目录中的

      mysql.server文件拷到/etc/init.d目录

      cp mysql.server /etc/init.d/mysql

      chmod 755 /etc/init.d/mysql

      创建硬链接:

      cd /etc/rc3.d(文本方式启动)

      ln -s /etc/init.d/mysql S85mysql

      ln -s /etc/init.d/mysql K85mysql

      cd /etc/rc5.d (图形方式启动)

      ln -s /etc/init.d/mysql S85mysql

      ln -s /etc/init.d/mysql K85mysql

      4.安装Apache2.0.45和PHP4.3.1

      tar -zxvf httpd-2.0.xx.tar.gz

      cd httpd_2.xx.xx

      /configure --prefix=/www --enable-so

      注:apache根目录为 /www

      make

      make install

      cd ..

      tar -zxvf php-4.3.x.tar.gz

      cd php-4.3.x

      /configure --prefix=/www/php --with-apxs2=/www/bin/apxs --with-config- filepath=/www/php --enable-sockets --with-mysql=/usr/local/mysql --with-zlibdir=/

      usr/local --with- gd

      注意:这些为一行,中间不要有回车。

      cp php.ini-dist /www/php/php.ini

      编辑httpd.conf(/www/conf):

      加入两行

      LoadModule php4_module modules/libphp4.so

      AddType application/x-httpd-php .php
