Step 1 :



sudo apt-get install python-software-properties

sudo add-apt-repository ppa:oisf/suricata-stable

sudo apt-get update

sudo apt-get install suricata htp



Step 2 :



To get the Emerging Threats rules :



cd /etc/suricata/



sudo wget https://rules.emergingthreatspro.com/open/suricata/emerging.rules.tar.gz



sudo tar -xvzf emerging.rules.tar.gz



sudo ln -s /etc/suricata/rules/reference.config /etc/suricata/reference.config



sudo ln -s /etc/suricata/UbuntuPPA-configs/classification.config /etc/suricata/classification.config



sudo cp /etc/suricata/UbuntuPPA-configs/suricata-ppa-1.4-6ubuntu6.yaml /etc/suricata/suricata.yaml



*** You can use reference.config and classification.config at /etc/suricata/rules.



sudo mkdir /var/log/suricata

sudo touch /etc/suricata/threshold.config



Step 3 :



sudo nano /etc/suricata/suricata.yaml



Locate the following lines :



default-log-dir: /usr/local/var/log/suricata/

default-rule-path: /usr/local/etc/suricata/rules

classification-file: /usr/local/etc/suricata/classification.config

reference-config-file: /usr/local/etc/suricata/reference.config

#pid-file: /var/run/suricata.pid

#- rule-reload: true

#threshold-file: /usr/local/etc/suricata/threshold.config



- drop

enable: no



Replace with the following lines :



default-log-dir: /var/log/suricata/

default-rule-path: /etc/suricata/rules

classification-file: /etc/suricata/classification.config

reference-config-file: /etc/suricata/reference.config

pid-file: /var/run/suricata.pid

- rule-reload: true

threshold-file: /usr/local/etc/suricata/threshold.config



- drop

enable: yes



To test if it work or not :



sudo suricata -c /etc/suricata/suricata.yaml -i eth0



Several minutes later, check the /var/log/suricata/stats.log and /var/log/suricata/http.log to see if there are some entries or not.



Step 4 :



sudo iptables -A INPUT -j NFQUEUE

sudo iptables -A OUTPUT -j NFQUEUE

sudo iptables -A FORWARD -j NFQUEUE



To test if it work or not :



sudo suricata -c /etc/suricata/suricata.yaml -q 0



Step 5 :



sudo apt-get install oinkmaster



sudo nano /etc/oinkmaster.conf



Append the following line :



url = https://rules.emergingthreatspro.com/open/suricata/emerging.rules.tar.gz



sudo oinkmaster -C /etc/oinkmaster.conf -o /etc/suricata/rules



Step 6 :



When everything is working fine, you can put them in the /etc/rc.local just right above "exit 0" :



#iptables -F

iptables -A INPUT -j NFQUEUE

iptables -A OUTPUT -j NFQUEUE

iptables -A FORWARD -j NFQUEUE



/etc/suricata/ips



Then create a file /etc/suricata/ips :



sudo nano /etc/suricata/ips

suricata -D -c /etc/suricata/suricata.yaml -q 0

oinkmaster -C /etc/oinkmaster.conf -o /etc/suricata/rules

kill -USR2 `pidof suricata`



chmod +x /etc/suricata/ips



Then you can write a cron job to update Emerging Threats Rules everyday.



sudo crontab -e



Append the following :



@daily /etc/suricata/update-rules



Then create the update-rule



sudo nano /etc/suricata/update-rules



oinkmaster -C /etc/oinkmaster.conf -o /etc/suricata/rules

kill -USR2 `pidof suricata`



sudo chmod +x /etc/suricata/update-rules





Remarks :



If you want to create a user-interface for the IPS, you can refer to the "Reference" item [12].



If the Suricata acts as IPS gateway, it requires to bridge 2 NICs and 1 NIC for management purpose. In addition, you need to do some changes on the configure files.



If you have 4-cores CPU, you need to change the settings as the following :



iptables -A INPUT -j NFQUEUE --queue-balance 0:3

iptables -A OUTPUT -j NFQUEUE --queue-balance 0:3

iptables -A FORWARD -j NFQUEUE --queue-balance 0:3



suricata -D -c /etc/suricata/suricata.yaml -q 0 -q 1 -q 2 -q 3
