Wazuh for Amazon AWS Cloudformation

Slack Email Documentation Web

This repository contains CloudFormation templates and provision scripts to deploy both a Wazuh production-ready environment and a Wazuh demo environment in Amazon Web Services (AWS):

Production-ready environment:

  • A VPC with two subnets, one for Wazuh servers, and another for Elastic Stack
  • Wazuh managers cluster with two nodes, a master and a worker
  • An Elasticsearch cluster with a minimum of 3 data nodes, auto-scalable to a maximum of 6 nodes
  • A Kibana node that includes a local elasticsearch client node, and an Nginx for HTTP basic authentication
  • Wazuh servers sit behind an internet-facing load balancer for agents to communicate with the cluster
  • Kibana server sit behind an internet facing load balancer, that optionally loads an SSL Certificate for HTTPS
  • Route53 DNS records for the loadbalancer, Wazuh and Elastic Stack nodes (optional).

Demo environment:

  • A VPC with two subnets, one for Wazuh servers, and another for Elastic Stack
  • Wazuh managers cluster with two nodes, a master and a worker
  • An Elasticsearch cluster with a minimum of 3 data nodes, auto-scalable to a maximum of 6 nodes
  • A Kibana node that includes a local elasticsearch client node, and an Nginx for HTTP basic authentication
  • Wazuh servers sit behind an internet-facing load balancer for agents to communicate with the cluster
  • Kibana server sit behind an internet facing load balancer, that optionally loads an SSL Certificate for HTTPS
  • A Splunk Indexer instance with a Splunk app for Wazuh installed on it.
  • Six Wazuh agents installed on different operating systems: Red Hat 7, CentOS 7, Ubuntu, Debian, Amazon Linux and Windows.
