Exchange Security Insights On-Premise Parser Does not Pick Up All Data #10020

Closed NickNicolaou2129 closed 7 months ago

NickNicolaou2129 commented 8 months ago

Describe the bug Hi, the parse for the Exchange Security Insights Online connector misses out valuable fields

To Reproduce Steps to reproduce the behavior:

Go to LAW and open Logs Search the table ESIExchangeConfig_CL View the logs in RawData column, we see that the logs within here are not parsed: ESIExchangeConfig_CL

Example: {"Parentgroup":"Exchange Windows Permissions","Level":1,"ObjectClass":"group","MemberPath":"Exchange Windows Permissions\Exchange Trusted Subsystem","ObjectGuid":"XXXX","Members":[{"SamAccountName":"REDACTED$","SID":"S-1-5-21-1310785037-698004181-1737509496-82221","DistinguishedName":"CN=REDACTED,OU=Member,OU=Server,OU=Company,DC=sys,DC=net","Name":"REDACTED","ObjectClass":"computer","ObjectGuid":"REDACTED","PropertyNames":"distinguishedName name objectClass objectGUID SamAccountName SID","AddedProperties":"","RemovedProperties":"","ModifiedProperties":"","PropertyCount":6,"distinguishedName":"CN=REDACTED,OU=Member,OU=Server,OU=Company,DC=sys,DC=net","name":"WEXCHG005760","objectClass":"computer","objectGUID":"55a37265-06cb-4082-b4ab-cab00f32e568"},{"SamAccountName":"REDACTED$","SID":"S-1-5-21-1310785037-698004181-1737509496-83666","DistinguishedName":"CN=WEXCHG005759,OU=Member,OU=Server,OU=Company,DC=sys,DC=net","Name":"REDACTED","ObjectClass":"computer","ObjectGuid":"cfb3b172-0d60-4879-b655-0658490a694f","PropertyNames":"distinguishedName name objectClass objectGUID SamAccountName SID","AddedProperties":"","RemovedProperties":"","ModifiedProperties":"","PropertyCount":6,"distinguishedName":"CN=REDACTED,OU=Member,OU=Server,OU=Company,DC=sys,DC=net","name":"WEXCHG005759","objectClass":"computer","objectGUID":"cfb3b172-0d60-4879-b655-0658490a694f"}],"LastLogon":null,"LastPwdSet":null,"Enabled":null,"HasMbx":null,"SamAccountName":null,"CanonicalName":null,"UserPrincipalName":null,"DN":"CN=Exchange Trusted Subsystem,OU=Microsoft Exchange Security Groups,DC=sys,DC=net","LastLogonString":null,"LastPwdSetString":null}

I have already sent an export that you can analyse the raw data from to parse what is not already parsed.

Expected behavior All data in the RAW data column should be correctly parsed and presented as a column in the log results.
