----------------------------------
Summary: Unable to Call ENRICHMENT_GET from Threat Triage Rule
'Reason' Field
Key: METRON-2326
URL: https://issues.apache.org/jira/browse/METRON-2326
Project: Metron
Issue Type: Bug
Reporter: Nick Allen
Assignee: Nick Allen
A Threat Triage Rule's "reason" field can contain executable Stellar to provide
an operator context as to why a rule fired during Threat Triage. I am unable
to call any function that requires a StellarContext during initialization, from
the 'Reason' field of a Threat Triage Rule. For example, I cannot call
`ENRICHMENT_GET`.
h3. Steps to Replicate
1. Create a simple file called `user.csv`.
{code:java}
[root@node1 ~]# cat user.csv
jdoe,192.168.138.2
jane,192.168.66.1
ciana,192.168.138.158
danixa,95.163.121.204
jim,192.168.66.121
{code}
2 . Create a file called `user-extractor.json`.
{code:java}
{
"config": {
"columns": {
"user": 0,
"ip": 1
},
"indicator_column": "ip",
"separator": ",",
"type": "user"
},
"extractor": "CSV"
}
{code}
3. Import the enrichment data.
{code:java}
source /etc/default/metron
$METRON_HOME/bin/flatfile_loader.sh -i ./user.csv -t enrichment -c t -e
./user-extractor.json
{code}
4. Validate that the enrichment loaded successfully.
{code:java}
[root@node1 0.7.2]# source /etc/default/metron
[root@node1 0.7.2]# $METRON_HOME/bin/stellar -z $ZOOKEEPER
[Stellar]>>> ip_dst_addr := "192.168.138.2"
192.168.138.2
[Stellar]>>> ENRICHMENT_GET('user', ip_dst_addr, 'enrichment', 't')
\{ip=192.168.138.2, user=jdoe}
{code}
5. Create a threat triage rule that attempts an ENRICHMENT_GET.
{code}
[Stellar]>>> conf := SHELL_EDIT()
{
"enrichment": {
"fieldMap": {
"stellar": {
"config": {
"is_alert": "true"
}
}
},
"fieldToTypeMap": {},
"config": {}
},
"threatIntel": {
"fieldMap": {},
"fieldToTypeMap": {},
"config": {},
"triageConfig": {
"riskLevelRules": [
{
"name": "Rule",
"comment": "This rule does not work when executing the 'reason' field.",
"rule": "true",
"reason": "FORMAT('Call to ENRICHMENT_GET=%s', ENRICHMENT_GET('user',
ip_dst_addr, 'enrichment', 't'))",
"score": "100"
}
],
"aggregator": "MAX",
"aggregationConfig": {}
}
},
"configuration": {}
}
[Stellar]>>> CONFIG_PUT("ENRICHMENT", conf, "snort")
{code}
6. The Storm worker logs for Enrichment show the following error.
