基于Ubuntu14.04下Suricata&＃xff08;一款高性能的网络IDS、IPS和网络安全监控引擎&＃xff09;的搭建&＃xff08;图文详解&＃xff09;&＃xff08;博主推荐&＃xff09;
参考官网
https://redmine.openinfosecfoundation.org/projects/suricata/wiki/_Logstash_Kibana_and_Suricata_JSON_output
注意&＃xff0c;这官网&＃xff0c;默认是适合Ubuntu系统的安装手法。
首先&＃xff0c;
Make sure your Suricata is compiled/installed with libjansson support enabled:
[root&＃64;suricata ~]# suricata --build-info
This is Suricata version 3.1 RELEASE

[root&＃64;suricata ~]#
然后&＃xff0c;需要配置
Configure suricata
[root&＃64;suricata suricata-3.1]# pwd
/root/suricata-3.1
[root&＃64;suricata suricata-3.1]# ls

[root&＃64;suricata suricata-3.1]# sudo vim suricata.yaml

改为

然后&＃xff0c;接下是安装
Install ELK (elasticsearch, logstash, kibana)
先卸载自带的openjdk
rpm -qa|grep java
rpm -e --nodeps tzdata-java-2013g-1.el6.noarch
rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
注意&＃xff1a;这里一定要是jdk1.8&＃xff0c;不然会报如下错误
[root&＃64;suricata ~]# sudo /etc/init.d/elasticsearch start
Starting elasticsearch: Elasticsearch requires at least Java 8 but your Java version from /usr/local/jdk/jdk1.7.0_79/bin/java does not meet this requirement[FAILED]
[root&＃64;suricata ~]#
官网提示了&＃xff0c;建议安装orcal 的 jdk。
我这里安装jdk18。
[root&＃64;suricata suricata-3.1]# cd /usr/local/
[root&＃64;suricata local]# ls
bin etc games include lib lib64 libexec sbin share src var
[root&＃64;suricata local]# mkdir jdk
[root&＃64;suricata local]# cd jdk/
[root&＃64;suricata jdk]# pwd
/usr/local/jdk
[root&＃64;suricata jdk]# ll
total 0
[root&＃64;suricata jdk]# rz
[root&＃64;suricata jdk]# pwd
/usr/local/jdk
[root&＃64;suricata jdk]# ll
total 176992
-rw-r--r--. 1 root root 181238643 Sep 3 2016 jdk-8u60-linux-x64.tar.gz
[root&＃64;suricata jdk]# tar -zxvf jdk-8u60-linux-x64.tar.gz
然后&＃xff0c;再vim /etc/profile
#java
export JAVA_HOME&＃61;/usr/local/jdk/jdk1.8.0_60
export CLASSPATH&＃61;.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH&＃61;$PATH:$JAVA_HOME/bin
文件生效
source /etc/profile
然后&＃xff0c;接下来就是安装ELk和配置JDK。&＃xff08;注意以下只是个例子&＃xff09;
wget https://download.elasticsearch.org/kibana/kibana/kibana-3.0.0.tar.gz
wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.6.1.deb
wget https://download.elastic.co/logstash/logstash/packages/debian/logstash_1.5.3-1_all.deb
tar -C /var/www/ -xzf kibana-3.0.0.tar.gz
dpkg -i elasticsearch-1.6.1.deb
dpkg -i logstash_1.5.3-1_all.deb
我这里啊&＃xff0c;Elasticsearch选取5.5.0
所以&＃xff0c;总的是
[root&＃64;suricata ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.0.deb
[root&＃64;suricata ~]# wget https://artifacts.elastic.co/downloads/logstash/logstash-5.5.0.deb
[root&＃64;suricata ~]# wget https://artifacts.elastic.co/downloads/kibana/kibana-5.5.0-linux-x86_64.tar.gz
最后下载&＃xff0c;得到
[root&＃64;suricata ~]# pwd
/root
[root&＃64;suricata ~]# ls
anaconda-ks.cfg Desktop Downloads install.log kibana-5.5.0-linux-x86_64.tar.gz Music Public suricata-3.1.tar.gz Videos
data Documents elasticsearch-5.5.0.deb install.log.syslog logstash-5.5.0.deb Pictures suricata-3.1 Templates
[root&＃64;suricata ~]#
然后&＃xff0c;进行对kibana的安装
[root&＃64;suricata ~]# pwd
/root
[root&＃64;suricata ~]# ls
anaconda-ks.cfg Desktop Downloads install.log kibana-5.5.0-linux-x86_64.tar.gz Music Public suricata-3.1.tar.gz Videos
data Documents elasticsearch-5.5.0.deb install.log.syslog logstash-5.5.0.deb Pictures suricata-3.1 Templates
[root&＃64;suricata ~]# tar -C /var/www/ -xzf kibana-5.5.0-linux-x86_64.tar.gz
得到
[root&＃64;suricata www]# pwd
/var/www
[root&＃64;suricata www]# ls
cgi-bin error html icons kibana-5.5.0-linux-x86_64
[root&＃64;suricata www]#
若大家没安装过这个命令&＃xff0c;则安装下即可。
[root&＃64;suricata ~]# yum -y install dpkg
然后&＃xff0c;进行对elasticsearch的安装
[root&＃64;suricata ~]# pwd
/root
[root&＃64;suricata ~]# ls
anaconda-ks.cfg Desktop Downloads install.log kibana-5.5.0-linux-x86_64.tar.gz Music Public suricata-3.1.tar.gz Videos
data Documents elasticsearch-5.5.0.deb install.log.syslog logstash-5.5.0.deb Pictures suricata-3.1 Templates
[root&＃64;suricata ~]# dpkg -i elasticsearch-5.5.0.deb
这里啊&＃xff0c;我建议大家还是去安装tar.gz包&＃xff0c;这种方式比较好。
所以&＃xff0c;后面&＃xff0c;我还是下载了&＃xff0c;rpm包&＃xff0c;以这种方式来进行安装。
[root&＃64;suricata ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.0.rpm
[root&＃64;suricata ~]# wget https://artifacts.elastic.co/downloads/logstash/logstash-5.5.0.rpm
进行elasticsearch-5.5.0的安装
[root&＃64;suricata ~]# pwd
/root
[root&＃64;suricata ~]# ls
anaconda-ks.cfg Desktop Downloads elasticsearch-5.5.0.rpm install.log.syslog logstash-5.5.0.deb Music Public suricata-3.1.tar.gz Videos

[root&＃64;suricata ~]# rpm -ivh elasticsearch-5.5.0.rpm

安装完&＃xff0c;默认即有
然后&＃xff0c;进行logstash的安装
[root&＃64;suricata ~]# pwd
/root
[root&＃64;suricata ~]# ls
anaconda-ks.cfg Desktop Downloads elasticsearch-5.5.0.rpm install.log.syslog logstash-5.5.0.deb Music Public suricata-3.1.tar.gz Videos

[root&＃64;suricata ~]#
安装完&＃xff0c;默认即有
然后&＃xff0c;下面是
Logstash configuration
[root&＃64;suricata conf.d]# pwd
/etc/logstash/conf.d
[root&＃64;suricata conf.d]# ll
total 0
[root&＃64;suricata conf.d]# touch /etc/logstash/conf.d/logstash.conf
插入如下内容
input {file { path &＃61;> ["/var/log/suricata/eve.json"]sincedb_path &＃61;> ["/var/lib/logstash/"]codec &＃61;> json type &＃61;> "SuricataIDPS" }}filter {if [type] &＃61;&＃61; "SuricataIDPS" {date {match &＃61;> [ "timestamp", "ISO8601" ]}ruby {code &＃61;> "if event[&＃39;event_type&＃39;] &＃61;&＃61; &＃39;fileinfo&＃39;; event[&＃39;fileinfo&＃39;][&＃39;type&＃39;]&＃61;event[&＃39;fileinfo&＃39;][&＃39;magic&＃39;].to_s.split(&＃39;,&＃39;)[0]; end;" }}if [src_ip] {geoip {source &＃61;> "src_ip" target &＃61;> "geoip" #database &＃61;> "/opt/logstash/vendor/geoip/GeoLiteCity.dat" add_field &＃61;> [ "[geoip][coordinates]", "%{[geoip][longitude]}" ]add_field &＃61;> [ "[geoip][coordinates]", "%{[geoip][latitude]}" ]}mutate {convert &＃61;> [ "[geoip][coordinates]", "float" ]}if ![geoip.ip] {if [dest_ip] {geoip {source &＃61;> "dest_ip" target &＃61;> "geoip" #database &＃61;> "/opt/logstash/vendor/geoip/GeoLiteCity.dat" add_field &＃61;> [ "[geoip][coordinates]", "%{[geoip][longitude]}" ]add_field &＃61;> [ "[geoip][coordinates]", "%{[geoip][latitude]}" ]}mutate {convert &＃61;> [ "[geoip][coordinates]", "float" ]}}}}
}output { elasticsearch {host &＃61;> localhost#protocol &＃61;> http}
}
然后&＃xff0c;再
Configure the start-up services
update-rc.d elasticsearch defaults 95 10 &＃xff08;这两个是ubuntu系统里的做法&＃xff0c;我这里是centos系统&＃xff0c;不需要&＃xff09;
update-rc.d logstash defaults
service httpd start 启动apache
service elasticsearch start
service logstash start
或者
启动服务sudo /etc/init.d/elasticsearch start
停止服务sudo /etc/init.d/elasticsearch stop
启动服务sudo /etc/init.d/logstash/start
停止服务sudo /etc/init.d/logstashstop
如果大家在启动过程中&＃xff0c;出现如下问题。
[root&＃64;suricata ~]# sudo /etc/init.d/elasticsearch start
which: no java in (/sbin:/usr/sbin:/bin:/usr/bin)
Could not find any executable java binary. Please install java in your PATH or set JAVA_HOME
[root&＃64;suricata ~]#
则见
ElasticSearch里JAVA环境丢失的问题
-rwxr-x---. 1 root root 5113 Jul 1 07:20 elasticsearch &＃xff0c;经过
[root&＃64;suricata init.d]# chmod 755 elasticsearch
[root&＃64;suricata init.d]# pwd
/etc/init.d
[root&＃64;suricata init.d]#
改为
-rwxr-xr-x. 1 root root 5113 Jul 1 07:20 elasticsearch
大家&＃xff0c;自行按照自己的jdk位置。
export JAVA_HOME&＃61;/usr/local/jdk/jdk1.8.0_60
然后&＃xff0c;就可以成功了。
[root&＃64;suricata ~]# sudo /etc/init.d/elasticsearch start
Starting elasticsearch: [ OK ]
[root&＃64;suricata ~]#
然后&＃xff0c;大家也许在启动&＃xff0c;会遇到这样的问题&＃xff1a;
Logstash默认的配置文件位置为./config和/etc/logstash/&＃xff0c;后者已经存在&＃xff0c;但直接运行依然会报错&＃xff1a;
WARNING: Could not find logstash.yml which is typically located in $LS_HOME/config or /etc/logstash.
见
Logstash使用grok解析IIS日志
简单起见&＃xff0c;直接在Logstash根目录创建软链接即可&＃xff1a;
cd /usr/share/logstash
[root&＃64;suricata logstash]# pwd
/usr/share/logstash
[root&＃64;suricata logstash]# ln -s /etc/logstash ./config
[root&＃64;suricata logstash]#
设置配置文件实时生效&＃xff0c;从而不用频繁地启停Logstash。
修改/etc/logstash/logstash.yml
config.reload.automatic: true
Logstash的运行
与Elasticsearch、Kibana不同&＃xff0c;Logstash默认并不作为系统服务安装&＃xff0c;我们也不建议作为服务启动。主要原因为&＃xff1a;大多数情况下&＃xff0c;Elasticsearch、Kibana在每台服务器上只有一个实例&＃xff0c;可以作为服务启动&＃xff1b;而一个Logstash实例一般只服务于一个数据流&＃xff0c;因此一台服务器上经常运行多个实例 。编写一个配置文件helloworld.conf进行测试。注意&＃xff0c;不要把该文件放在/etc/logstash/conf.d下&＃xff0c;以避免不同实例间产生混淆&＃xff0c;因为该文件夹是Logstash默认读取的文件夹。简单起见&＃xff0c;可直接放在Logstash根目录下。
input { stdin {}
}
output { stdout {}
}
这是一个命令行输入、命令行输出的Logstash实例&＃xff0c;运行成功则说明已配置正确&＃xff1a;
bin/logstash -f helloworld.conf
虽然如此&＃xff0c;很多时候我们还是希望各个Logstash实例能随系统而启动并在后台运行。将其加入计划任务即可&＃xff1a;
nohup /usr/share/logstash/bin/logstash -f /usr/share/logstash/helloworld.conf > /dev/null &
然后&＃xff0c;
Now make sure Suricata is running and you have logs written in your JSON log files
http://localhost/kibana-5.5.0
