Wazuh由部署到受监视系统的端点安全代理和管理服务器组成，管理服务器收集和分析代理收集的数据。此外，Wazuh已与Elastic Stack完全集成，提供了搜索引擎和数据可视化工具，使用户可以浏览其安全警报。
Wazuh提供的功能包括日志数据分析，入侵和恶意软件检测，文件完整性监视，配置评估，漏洞检测以及对法规遵从性的支持。
本次将部署一套分布式Wazuh方案：
- wazuh-master启用全功能组件；ElasticStack将使用官方基本授权，不启用X-pack和加密连接；Linux版本Agent将安装到Kibana主机和ElasticSearch主机上，不再额外安装示例主机；各个功能组件采用单节点部署；Wazuh使用4.1.5版本，搭配官方指定7.11.2ElasticStack版本。部署方案
部署拓扑
网络地址
| 系统角色 | 版本 | 网络地址 |
|---|---|---|
| ElasticSearch | 7.11.2 | 192.168.248.146 |
| Kibana | 7.11.2 | 192.168.248.145 |
| WazuhMaster | 4.1.5 | 192.168.248.150 |
| WazuhAgent | 4.1.5 | 192.168.248.1 |
