Thanks.
But don't work. It only decode srcip field. Attach the output:
**Phase 1: Completed pre-decoding.
full event: 'WinEvtLog: Security: AUDIT_FAILURE(5152):

**Phase 2: Completed decoding.
decoder: 'windows'
srcip: '10.20.10.55'
**Rule debugging:
Trying rule: 6 - Generic template for all windows rules.
*Rule 6 matched.
*Trying child rules.
Trying rule: 7301 - Grouping of Symantec AV rules from eventlog.
Trying rule: 18100 - Group of windows rules.
*Rule 18100 matched.
*Trying child rules.
Trying rule: 18101 - Windows informational event.
Trying rule: 18102 - Windows warning event.
Trying rule: 18104 - Windows audit success event.
Trying rule: 18103 - Windows error event.
Trying rule: 18105 - Windows audit failure event.
**Phase 3: Completed filtering (rules).
Rule id: '18100'
Level: '0'
Description: 'Group of windows rules.'
So, the original fields of decoder has been erased (status, id, extra_data,
srcuser, system_name, name, location, user, system_name). The consecuence
is that orginal rules don't match.
