| 2025-06-17 | Enhancement:
- Modified a conditional mapping for the `log_source` field. Added a grok pattern to identify IP addresses. When an IP is found, it is mapped to `event.idm.read_only_udm.intermediary.ip` and `event.idm.read_only_udm.intermediary.asset.ip`.Otherwise, Added a grok pattern to identify hostnames. When a hostname is found, it is mapped to `event.idm.read_only_udm.intermediary.hostname` and `event.idm.read_only_udm.intermediary.asset.hostname`. Otherwise, the existing mapping to `event.idm.read_only_udm.security_result.about.labels` is used. - event.idm.read_only_udm.principal.file.full_path: Newly mapped `process` raw log field with `event.idm.read_only_udm.principal.file.full_path` UDM field. |

This field was previously uninitialized. - Refactored `msg_data.HostId`, `msg_data.FileTrust`, `msg_data.Message`, `msg_data.PathName`, `msg_data.HostName`, `msg_data.FileHash`, `msg.host.hostname`, `msg_data.ProcessPathName`, `msg_data.ProcessPath`, `msg.log.file.path`, `msg_data.HostIP`, `msg_data.UserName`, `msg.agent.id`, `msg.agent.type`, `msg.agent.name`, `msg.agent.ephemeral_id`, `msg.host.id`, `msg.host.architecture` and `msg.host.os.platform` these fields mapping from the single `rename` block with multiple `replace` blocks with individual `on_error` handlers, improving robustness. - Modified `mac` address Changed the source field from `host_mac` to `msg.host.mac` in the `for` loop. |
