In order to make suricata process these rules we'll have to update its configuration. First get a list of all the rules in /etc/suricata/rules with something like: # ls /etc/suricata/rules/*.rules We need to make sure all these rule files are listed in the suricata configuration, so open up /etc/suricata/suricata.yaml and check the rule-files section against the list of rule files. The rule-files section in my suricata.yaml looks like this: The rule header contains the rule’s action, protocol, source IP address/netmask and port, destination IP address/netmask and port, and traffic direction. The rule options can contain alert messages, references (cve, bugtraq, Nessus etc.), revision etc. Information on writing Snort and Suricata rules, as well as detailed descriptions of all the fields can be found in the Snort manual8 and on the Suricata website9. Suricata loads signatures with which the network traffic will be compared using netmap to control packets before they are delivered to the firewall.In order for the writer (syslog daemon) and reader (Sagan) to be able to share data, there has to be a standard between the two. Traditionally, Sagan required the syslog daemon to write data to the file in a very specific format. This was done by a delimiting the data via the ‘|’ (pipe) symbol. This format was similar to a CSV file.
