Comments

Additional method to increase risk in ad-hoc fashion is via SPL. Additional benefit to SPL method, is ability to simultaneously update risk scores for system and user objects.

```
| localop | stats count | eval dest="vladimir_foo", user="vladimir_bar"
| eval risk_object=dest | sendalert risk param._risk_object_type="system" param._risk_score=42
| eval risk_object=user | sendalert risk param._risk_object_type="user" param._risk_score=12
```

You are able to later spot check the score, by running:

```
index=risk sourcetype=stash risk_object="vladimir*" | table _time risk_object risk_object_type source description risk_score
```

Also, this is documented at http://dev.splunk.com/view/enterprise-security/SP-CAAAFBD
