Bulk Loading Threat Intelligence Sources

You can bulk load threat intelligence information from the following sources:

• CSV Ingestion

• HDFS through MapReduce

• Taxii Loader

CSV File

The shell script $METRON_HOME/bin/flatfile_loader.sh reads data from local disk and loads the threat intelligence data into an HBase table. This loader uses the special configuration parameter inputFormatHandler to specify how to consider the data. The two implementations are BY_LINE and org.apache.metron.dataloads.extractor.inputformat. WholeFileFormat.

The default is BY_LINE, which makes sense for a list of CSVs in which each line indicates a unit of information to be imported. However, if you are importing a set of STIX documents, then you want each document to be considered as input to the Extractor.

Start the user parser topology by running the following:

$METRON_HOME/bin/start_parser_topology.sh -s user -z $ZOOKEEPER_HOST:2181 -k $KAKFA_HOST:6667

The parser topology listens for data streaming in and pushes the data to HBase. Now you have data flowing into the HBase table, but you need to ensure that the enrichment topology can be used to enrich the data flowing past.

The parameters for the utility are as follows:

HDFS via MapReduce

                           $METRON_HOME/bin/flatfile_loader.sh -i /tmp/top-10k.csv -t enrichment -c t -e ./extractor.json -m MR
                        

The parameters for the utility are as follows:

Taxii Loader

The shell script $METRON_HOME/bin/threatintel_taxii_load.sh can be used to poll a Taxii server for STIX documents and ingest them into HBase. Taxii loader is a stand-alone Java application that never stops.

It is quite common for this Taxii server to be an aggregation server such as Soltra Edge.

In addition to the Enrichment and Extractor configs described in the following sections, this loader requires a configuration file describing the connection information to the Taxii server. The following is an example of a configuration file:

                        {
   "endpoint" : "http://localhost:8282/taxii-discovery-service"
  ,"type" : "DISCOVER"
  ,"collection" : "guest.Abuse_ch"
  ,"table" : "threat_intel"
  ,"columnFamily" : "cf"
  ,"allowedIndicatorTypes" : [ "domainname:FQDN", "address:IPV_4_ADDR" ]
}

                     

where:

endpoint

The URL of the endpoint

type

POLL or DISCOVER depending on the endpoint.

collection

The Taxii collection to ingest

table

The HBase table to import into

columnFamily

The column family to import into

allowedIndicatorTypes

an array of acceptable threat intelligence types (see the "Enrichment Type Name" column of the Stix table above for the possibilities).
