OTX Suricata Rule Generator

The OTX Suricata Rule Generator can be used to create the rules and configuration for Suricata to alert on indicators from your OTX account (otx.alienvault.com). This is done with the suricata IP Reputation and file extraction features. For every pulse your are subscribed to this will add the all the IPv4 indicators in every pulse to a generated IP reputation file. It will also create a suricata MD5 file for each pulse that has MD5 indicators, there will be a corresponding rule generated that corresponds with each of these files.

BETA NOTICE

This is under active development. It has been tested in our lab in scenarios to replicate realworld installs. However, Suricata is a complicated product with many configuration options. If you have anything other than a default configuration, please adapt the output of this tool as appropriate. As always feedback and improvements are welcome!
