Snort是一款知名的开源的入侵检测系统。其 Web界面(Snorby)可以用于更好地分析警告。Snort使用iptables/pf防火墙来作为入侵检测系统,下面为大家详细讲解一下Linux下配置Snort具体方法。
第一步:预装daq所需程序
snort使用数据采集器(daq)监听防火墙数据包队列,所以按照daq。需预装的程序有:flex、bison、libcap。
sudo apt-get install flex
sudo apt-get install bison
sudo aptitude install libpcap-dev
第二步:安装daq
wget https://www.snort.org/downloads/snort/daq-2.0.6.tar.gz
tar xvfz daq-2.0.6.tar.gz
cd daq-2.0.6
./configure && make && sudo make install
第三步:安装snort所需程序
aptitude install libpcre3-dev
aptitude install libdumbnet-dev
aptitude install zlib1g-dev
第四步:安装snort
wget https://www.snort.org/downloads/snort/snort-2.9.12.tar.gz
tar xvfz snort-2.9.12.tar.gz
cd snort-2.9.12
./configure --enable-sourcefire && make && sudo make install
第五步:运行 snort 会要求你安装响应包,安装即可
//运行snort -V
//提示安装下面包
apt-get install snort
apt-get install snort-mysql
apt-get install snort-pgsql//此时snort已经可以运行,看到一只小猪
,,_ –> Snort! – o” )~ Version 2.9.2 IPv6 GRE (Build 78) ”” By Martin Roesch & The Snort Team: http://www.snort.org/snort/snort-team Copyright (C) 1998-2011 Sourcefire, Inc., et al. Using libpcap version 1.1.1 Using PCRE version: 8.12 2011-01-15 Using ZLIB version: 1.2.3.4
//-----------------
//安装一些依赖包,为后面的图形化做准备
安装apache
apt-get install apache2
安装mysql
apt-get install mysql-server
安装php
apt-get install php5
第六步:为snort创建一个数据库,和一个用户
$ mysql –u root –p
mysql> CREATE DATABASE snort;
mysql> grant CREATE, INSERT, SELECT, UPDATE on snort.* to snort@localhost;
mysql> grant CREATE, INSERT, SELECT, UPDATE on snort.* to snort;
mysql> SET PASSWORD FOR snort@localhost=PASSWORD('yourpassword');
mysql> exit
第七步:修改snor配置文件
snort的配置文件在/etc/snort/snort.conf
打开该文件将 HOME_NET 有关项注释掉,然后将 HOME_NET 设置为本机 IP 所在网络,将 EXTERNAL_NET 相关项注释掉,设置其为非本机网络,如下所示:
其中需要修改的内容如下所示: 45行 ipvar HOME_NET any > ipvar HOME_NET 192.168.x.x 你的的IP网段,写成CIDR格式,可以添加多个网段 举例:ipvar HOME_NET [192.168.0.0/16,172.16.0.0/16]
ipvar EXTERNAL_NET any > ipvar EXTERNAL_NET!$HOME_NET
第八步:试运行
snort -T -i eth0 -u snort -g snort -c /etc/snort/snort.conf
若出现如下错误
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!! WARNING: The database output plugins are considered deprecated as
!! of Snort 2.9.2 and will be removed in Snort 2.9.3.
!! The recommended approach to logging is to use unified2 with
!! barnyard2 or similar.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
database: must enter database name in configuration file
解法:
搞了好长时间,发现snort.conf配置文件549行左右有一条
include database.conf
注释掉
第九步:运行snort,snort会监测eth0端口
snort
结果如下
