Linux下的IDS测试(2)

这几个操作的含义和Libpcap相反)
然后,我们将对SNORT作一系列的调试,使其正常运转,也随意纰漏管理

[root@kykin-L-linux snort-1.9.0]# cp etc /usr/local/snort19 –r
(复制以后文件夹下的ETC目录到SNORT19上面)
[root@kykin-L-linux snort-1.9.0]# cp rules /usr/local/snort19 –r
(复制全部划定规矩文件)
[root@kykin-L-linux snort-1.9.0]# cp etc/>

做完这一些,我们的任务已经完成了一大局部。上面我们将完成对照次要的一局部。入侵检测的划定规矩定制
[root@kykin-L-linux snort-1.9.0]#vi /root/.snortrc
# This file contains a sample snort configuration.
# You can take the following steps to create your
# own custom configuration:
#
# 1) Set the network variables for your network
# 2) Configure preprocessors
# 3) Configure output plugins
# 4) Customize your rule set
#




# Step #1: Set the network variables:
#
# You must change the following variables to reflect
# your local network. The variable is currently
# setup for an RFC 1918 address space.
#
# You can specify it explicitly as:
#
# var HOME_NET 10.1.1.0/24



(内容太多,且则省略)
首先。我们在整个config文件的102行找到:
var RULE_PATH ../rules


这个是本地寄存划定规矩的路子,我们必需按照本身的现象,无缺写出来
我的文件是如许的:
var RULE_PATH /usr/local/snort19/rules


然后,在config文件的590行。我们将会望见:
include $RULE_PATH/bad-traffic.rules


从这里入手动手,赓续到后背,就是SNORT的整个划定规矩纠合。我们必需按照本身的现象作出注意的调试
include $RULE_PATH/bad-traffic.rules
include $RULE_PATH/exploit.rules
include $RULE_PATH/scan.rules
include $RULE_PATH/finger.rules
include $RULE_PATH/ftp.rules
include $RULE_PATH/telnet.rules
include $RULE_PATH/rpc.rules
include $RULE_PATH/rservices.rules
include $RULE_PATH/dos.rules


(文件的内容太多,且则省略)
你可以针对本身的体系的详细现象做出注意的划定规矩剖析,不必要的划定规矩,就采用#注释的编制往复失
为了可实验指令:SNORT的随意纰漏调用,我们将做出毗连剖析
[root@kykin-L-linuxsnort-1.9.0]#ln –s /usr/local/snort19/bin/snort /usr/sbin/snort


然后。我们将树立一个新的目录来寄存SNORT日志文件
[root@kykin-L-linux snort-1.9.0]#cd /var/log
[root@kykin-L-linux snort-1.9.0]#mkdir snort


做完上面的统统,基础上完成了整个IDS的起原设定,上面我们将测试能否成功
[root@kykin-L-linux snort-1.9.0]#snort
