I saw some odd behavior I think is unrelated to this PR itself while
testing.
I tried to remove the threat triage rule, messed up, fixed it, and then
borked my conf variable. After recovering I was able to successfully test (and
run THREAT_TRIAGE_REMOVE without breaking conf).
```
[Stellar]>>> conf
{
"enrichment" : {
"fieldMap" : {
"geo" : [ "ip_dst_addr", "ip_src_addr" ],
"host" : [ "host" ],
"stellar" : {
"config" : {
"is_alert" : "source.type == 'bro'"
}
}
},
"fieldToTypeMap" : { },
"config" : { }
},
"threatIntel" : {
"fieldMap" : {
"hbaseThreatIntel" : [ "ip_src_addr", "ip_dst_addr" ]
},
"fieldToTypeMap" : {
"ip_src_addr" : [ "malicious_ip" ],
"ip_dst_addr" : [ "malicious_ip" ]
},
"config" : { },
"triageConfig" : {
"riskLevelRules" : [ {
"name" : "Abnormal DNS Port",
"rule" : "source.type == \"bro\" and protocol == \"dns\" and
ip_dst_port != 53",
"score" : 10.0
} ],
"aggregator" : "MAX",
"aggregationConfig" : { }
}
},
"configuration" : { }
}
