Basic Setup
|
|
|
|
When using Debian or FreeBSD, make sure you enter all commands as root/super-
|
|
user because for these operating systems it is not possible to use 'sudo'.
|
|
Start with creating a directory for Suricata's log information.
|
|
|
|
sudo mkdir /var/log/suricata
|
|
|
|
|
|
To prepare the system for using it, enter:
|
|
|
|
sudo mkdir /etc/suricata
|
|
|
|
The next step is to copy classification.config, reference.config and
|
|
suricata.yaml from the base build/installation directory (ex. from git it will
|
|
be the oisf directory) to the /etc/suricata directory. Do so by entering the
|
|
following:
|
|
|
|
sudo cp classification.config /etc/suricata
|
|
sudo cp reference.config /etc/suricata
|
|
sudo cp suricata.yaml /etc/suricata
|
|
|
|
|
|
Auto setup
|
|
|
|
You can also use the available auto setup features of Suricata:
|
|
ex:
|
|
|
|
./configure && make && make install-conf
|
|
|
|
make install-conf
|
|
would do the regular "make install" and then it would automatically create/
|
|
setup all the necessary directories and suricata.yaml for you.
|
|
|
|
./configure && make && make install-rules
|
|
|
|
make install-rules
|
|
would do the regular "make install" and then it would automatically download
|
|
and set up the latest ruleset from Emerging Threats available for Suricata
|
|
|
|
./configure && make && make install-full
|
|
|
|
make install-full
|
|
would combine everything mentioned above (install-conf and install-rules) - and
|
|
will present you with a ready to run (configured and set up) Suricata
|
|
|
|
Setting variables
|
|
|
|
Make sure every variable of the vars, address-groups and port-groups in the
|
|
yaml file is set correctly for your needs. A full explanation is available in
|
|
the Rule_vars_section_of_the_yaml. You need to set the ip-address(es) of your
|
|
local network at HOME_NET. It is recommended to set EXTERNAL_NET to !$HOME_NET.
|
|
This way, every ip-address but the one set at HOME_NET will be treated as
|
|
external. It is also possible to set EXTERNAL_NET to 'any', only the
|
|
recommended setting is more precise and lowers the change that false positives
|
|
will be generated. HTTP_SERVERS, SMTP_SERVERS , SQL_SERVERS , DNS_SERVERS and
|
|
TELNET_SERVERS are by default set to HOME_NET. AIM_SERVERS is by default set at
|
|
'any'. These variables have to be set for servers on your network. All settings
|
|
have to be set to let it have a more accurate effect.
|
|
Next, make sure the following ports are set to your needs: HTTP_PORTS,
|
|
SHELLCODE_PORTS, ORACLE_PORTS and SSH_PORTS.
|
|
Finally, set the host-os-policy to your needs. See Host_OS_Policy_in_the_yaml
|
|
for a full explanation.

Interface cards
|
|
|
|
To check the available interface cards, enter:
|
|
|
|
ifconfig
|
|
|
|
Now you can see which one you would like Suricata to use.
|
|
To start the engine and include the interface card of your preference, enter:
|
|
|
|
sudo suricata -c /etc/suricata/suricata.yaml -i wlan0
|
|
|
|
Instead of wlan0, you can enter the interface card of your preference.
|
|
To see if the engine is working correctly and receives and inspects traffic,
|
|
enter:
|
|
|
|
cd /var/log/suricata
|
|
|
|
Followed by:
|
|
|
|
tail http.log
|
|
|
|
And:
|
|
|
|
tail -n 50 stats.log
|
|
|
|
To make sure the information displayed is up-dated in real time, use the -
|
|
f option before http.log and stats.log:
|
|
|
|
tail -f http.log stats.log
|
|
