Justin Leet updated METRON-157:
-------------------------------
Fix Version/s: (was: Next + 1)
0.7.1
> Create CEF Parser
> -----------------
>
> Key: METRON-157
> URL: https://issues.apache.org/jira/browse/METRON-157
> Project: Metron
> Issue Type: New Feature
> Reporter: Domenic Puzio
> Assignee: Kyle Richardson
> Priority: Minor
> Labels: platform
> Fix For: 0.7.1
>
>
> Create a parser for CEF (Common Event Format). CEF is a very common
> formatting for security data sources; it is used by FireEye, Adallom, Imperva
> WAF, CyberArk, and others. The parser should be flexible enough to work for
> any of these data sources. CEF uses shorthand field names, so field names
> should be changed to human-readable and Metron-friendly equivalents. CEF
> custom labels (cs1Label, flexString1Label, etc.) should be converted
> appropriately.
> Below are sample messages and their expected parsed output.
