Using Stellar to Set up Threat Triage Configurations
The threat triage configuration defines conditions by associating them with scores. Because this is a per-sensor configuration, this fits nicely within the sensor enrichment configuration held in ZooKeeper. This configuration fits well within the threatIntel section of the configuration like so:
{ ... ,"threatIntel" : { ... , "triageConfig" : { "riskLevelRules" : { "condition1" : level1 , "condition2" : level2 ... } ,"aggregator" : "MAX" } } }
- riskLevelRules
Correspond to the set of condition to numeric level mappings that define the threat triage for this particular sensor.
- aggregator
An aggregation function that takes all non-zero scores representing the matching queries from riskLevelRules and aggregates them into a single score.
The current supported aggregation functions are:
- MAX
The maximum of all of the associated values for matching queries
- MIN
The minimum of all of the associated values for matching queries
- MEAN
The mean of all of the associated values for matching queries
- POSITIVE_MEAN
The mean of the positive associated values for the matching queries
