Translate SID

edit

This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

The translate_sid processor translates a Windows security identifier (SID) into an account name. It retrieves the name of the account associated with the SID, the first domain on which the SID is found, and the type of account. This is only available on Windows.

Every account on a network is issued a unique SID when the account is first created. Internal processes in Windows refer to an account’s SID rather than the account’s user or group name and these values sometimes appear in logs.

If the SID is invalid (malformed) or does not map to any account on the local system or domain then this will result in the processor returning an error unless ignore_failure is set.

processors:
  - translate_sid:
      field: winlog.event_data.MemberSid
      account_name_target: user.name
      domain_target: user.domain
      ignore_missing: true
      ignore_failure: true
