解码 XML Wineventlog

编辑

此功能处于技术预览阶段,可能会在将来的版本中更改或删除。Elastic 将努力解决任何问题,但技术预览中的功能不受官方 GA 功能的支持 SLA 的约束。

decode_xml_wineventlog处理器解码存储在field键下的XML格式的Windows事件日志数据。它将结果输出到target_field

输出字段将与winlogbeat winlog 字段相同。

支持的配置选项如下:

field
(必填) 包含 XML 的源字段。默认为 message
target_field
(必填) 将解码的 XML 写入到的字段。要将解码的 XML 字段合并到事件的根目录,请使用空字符串指定 target_field (target_field: "")。默认值为 winlog
overwrite_keys
(可选) 一个布尔值,指定事件中已存在的键是否会被解码的 XML 对象中的键覆盖。默认值为 true
map_ecs_fields
(可选) 一个布尔值,指定是否尽可能映射额外的 ECS 字段。请注意,ECS 字段键位于 target_field 之外。默认值为 true
ignore_missing
(可选) 如果为 true,则当指定字段不存在时,处理器不会返回错误。默认为 false
ignore_failure
(可选) 忽略处理器产生的所有错误。默认为 false

示例

processors:
  - decode_xml_wineventlog:
      field: event.original
      target_field: winlog
{
  "event": {
    "original": "<Event xmlns='http://schemas.microsoft.com/win/2004/08/events/event'><System><Provider Name='Microsoft-Windows-Security-Auditing' Guid='{54849625-5478-4994-a5ba-3e3b0328c30d}'/><EventID>4672</EventID><Version>0</Version><Level>0</Level><Task>12548</Task><Opcode>0</Opcode><Keywords>0x8020000000000000</Keywords><TimeCreated SystemTime='2021-03-23T09:56:13.137310000Z'/><EventRecordID>11303</EventRecordID><Correlation ActivityID='{ffb23523-1f32-0000-c335-b2ff321fd701}'/><Execution ProcessID='652' ThreadID='4660'/><Channel>Security</Channel><Computer>vagrant</Computer><Security/></System><EventData><Data Name='SubjectUserSid'>S-1-5-18</Data><Data Name='SubjectUserName'>SYSTEM</Data><Data Name='SubjectDomainName'>NT AUTHORITY</Data><Data Name='SubjectLogonId'>0x3e7</Data><Data Name='PrivilegeList'>SeAssignPrimaryTokenPrivilege\n\t\t\tSeTcbPrivilege\n\t\t\tSeSecurityPrivilege\n\t\t\tSeTakeOwnershipPrivilege\n\t\t\tSeLoadDriverPrivilege\n\t\t\tSeBackupPrivilege\n\t\t\tSeRestorePrivilege\n\t\t\tSeDebugPrivilege\n\t\t\tSeAuditPrivilege\n\t\t\tSeSystemEnvironmentPrivilege\n\t\t\tSeImpersonatePrivilege\n\t\t\tSeDelegateSessionUserImpersonatePrivilege</Data></EventData><RenderingInfo Culture='en-US'><Message>Special privileges assigned to new logon.\n\nSubject:\n\tSecurity ID:\t\tS-1-5-18\n\tAccount Name:\t\tSYSTEM\n\tAccount Domain:\t\tNT AUTHORITY\n\tLogon ID:\t\t0x3E7\n\nPrivileges:\t\tSeAssignPrimaryTokenPrivilege\n\t\t\tSeTcbPrivilege\n\t\t\tSeSecurityPrivilege\n\t\t\tSeTakeOwnershipPrivilege\n\t\t\tSeLoadDriverPrivilege\n\t\t\tSeBackupPrivilege\n\t\t\tSeRestorePrivilege\n\t\t\tSeDebugPrivilege\n\t\t\tSeAuditPrivilege\n\t\t\tSeSystemEnvironmentPrivilege\n\t\t\tSeImpersonatePrivilege\n\t\t\tSeDelegateSessionUserImpersonatePrivilege</Message><Level>Information</Level><Task>Special Logon</Task><Opcode>Info</Opcode><Channel>Security</Channel><Provider>Microsoft Windows security auditing.</Provider><Keywords><Keyword>Audit Success</Keyword></Keywords></RenderingInfo></Event>"
  }
}

将产生以下输出
