Cherry-pick of PR #18436 to 7.8 branch. Original message:
What does this PR do?
Sometimes the DNS IP addresses from Sysmon in
winlog.event_data.QueryResults
are truncated.The leads to mapping exceptions since the value is not of type
ip
in Elasticsearch.To fix this the module will now filter any results that are not valid IP addresses.
Why is it important?
The issue causes mapping exceptions that could lead to dropped events.
