Create ECS compliant index templates

[AlexRuiz7]

Description

As part of the Data Persistence Model Redesign, new indices will appear in the Wazuh Indexer. We want these indices to be created automatically after Wazuh Indexer boots up. For that, we'll build a plugin.

As owners of the Wazuh Indexer, we will define the indices settings and fields. These need to be ECS compliant.

Tasks

• Define fields for stateful modules data #282
• Define the index data model (template) for the agents index.
• Define the index data model (template) for the stateful indices.
  • System Inventory
  • Processes Inventory
  • Packages Inventory
  • Network Inventory
  • Vulnerabilities
  • FIM
  • SCA
• Define the index data model (template) for the commands index.
• Define the index data model (template) for the wazuh-alerts (stateless) index.

Implementation restrictions

• agent.groups must be present on all indices but the commands index.
• Inventory is split in 4 indices:
  • inventory-system (host's info)
  • inventory-processes
  • inventory-networks
  • inventory-packages
• The agents index contains basic information about the host (IP, OS info)

Fields summary

The fields are based on wazuh/wazuh#23396 (comment)

Based on ECS Agent Fields.

Field	ECS field	Type	Description
uuid	agent.id	keyword	Agent's ID
name	agent.name	keyword	Agent's name
groups	*agent.groups	keyword	Agent's groups
internal_key	*agent.key	keyword	Agent's registration key
type	agent.type	keyword	Type of agent
version	agent.version	keyword	Agent's version
connection_status	*agent.is_connected	boolean	Agents' interpreted connection status depending on agent.last_login
last_keepalive	*agent.last_login	date	Agent's last login
ip	host.ip	ip	Host IP addresses. Note: this field should contain an array of values.
os_*	host.os.full	keyword	Operating system name, including the version or code name.

Fields summary

For this stage, we are using all the fields of the ECS. No custom fields are used. As a result, we are using the default mapping of the ECS.

• ECS main mappings

The generated template must match this one.

Hello. Please add agent.labels in Vulnerability Module the same way like in "Threat Hunting" module. Labels are awesome and can easy filter data based on personal entries in agent configuration.
