RedELK-Client : Deploying Cybersecurity Monitoring With Ansible

The RedELK client components using Ansible, a powerful automation tool that streamlines the installation and management of cybersecurity monitoring systems.

As RedELK enhances the capabilities of red teaming operations by aggregating data and providing insightful analytics, mastering its deployment is crucial for effective cybersecurity defenses.

We’ll detail the necessary configurations, dependencies, and steps to successfully integrate RedELK into your security infrastructure.

Variables

The following variables can be modified:

Key	Type	Default	Description
attack_scenario	string	`"redteam"`	Name of the red team attack scenario. Currently only one name is supported
es_deploy_beats	list	`["filebeat"]`	Set which beats to deploy (possible values: `filebeat` / `apm-server` / `auditbeat` / `heartbeat` / `metricbeat` / `nagioscheckbeat` / `packetbeat`)
es_version	string	`"7.16.3"`	Elastic version
optsec_dir	string	`"/opt"`	Base directory for components install (where customer data will be stored) – allows to store on an encrypted partition/disk
redelk_cert_path	string	`"certificates/redelk"`	Local path to store RedELK certificates. This should match the value of `redelk_cert_path` in `redelk-server` role.
redelk_server_host	string	`"localhost"`	Hostname or IP of the RedELK server (used for filebeat destination)
redelk_user	string	`"redelk"`	RedELK SSH username (used to sync data between RedELK monitoring server and the clients)
ssh_keys_path	string	`"ssh_keys"`	Local path to store ssh keys

Dependencies
