wget https://www.openinfosecfoundation.org/download/suricata-7.0.0.tar.gz
tar xzvf suricata-7.0.0.tar.gz
cd suricata-7.0.0/
./configure --enable-nfqueue --prefix=/usr --sysconfdir=/etc --localstatedir=/var
make
make install-full
运行
1、编辑/etc/suricata/suricata.yaml
修改如下:
第一个箭头处为抓包网卡名称
第二箭头处添加一行
2、
cd /var/lib/suricata/rules
新增自定义规则,创建test.rules,内容为
alert tcp any any -> any any (msg: "Http rule test!"; flow:to_server,established; http.uri; content:"suricata"; sid:3030303; rev:1;)
http报文中uri包含suricata字段,就会匹配中该规则
编辑/etc/suricata/suricata.yaml新增一行
3、
运行suricata,使用af-packet抓包
/usr/bin/suricata -c /etc/suricata/suricata.yaml --af-packet
回放http pcap文件uri中包含suricata字段即可
tcpreplay -i ens160 -M 50 test.pcap
tail -f fast.log,查看日志如下
08/19/2024-05:50:30.126731 [**] [1:3030303:1] Http rule test! [**] [Classification: (null)] [Priority: 3] {TCP} 192.168.1.4:62622 -> 192.168.1.5:8080
3030303就是自定义的规则id
调试
1、开启debug模式
执行configure时需要加上--enable-debug
./configure --enable-debug --enable-nfqueue --prefix=/usr --sysconfdir=/etc --localstatedir=/var
编辑/etc/suricata/suricata.yaml,default-log-level改成debug
执行: /usr/bin/suricata -c /etc/suricata/suricata.yaml --af-packet,会输出很多debug日志
