Elastic Agent 服务终止
编辑Elastic Agent 服务终止
编辑识别 Elastic 端点代理已停止并且不再在主机上运行。攻击者可能会尝试禁用安全监控工具,以试图在入侵期间逃避检测或预防功能。这也可能表明代理本身存在问题,应予以解决,以确保防御措施恢复到稳定状态。

如果在非 elastic-agent 索引(例如 beats)上启用 EQL 规则,对于版本 <8.2,事件将不会定义 event.ingested
,并且直到版本 8.2 才添加了 EQL 规则的默认回退。因此,为了使此规则有效,用户需要添加一个自定义摄取管道以将 event.ingested
填充到 @timestamp。有关添加自定义摄取管道的更多详细信息,请参阅 - https://elastic.ac.cn/guide/en/fleet/current/data-streams-pipeline-tutorial.html
