#23361

Description

Currently, our Wazuh documentation with the WAF integration shows the process through Kinesis, which is intended to be deprecated:
https://documentation.wazuh.com/current/cloud-security/amazon/services/supported-services/waf.html

The objective of this issue is to update this documentation to show the process through a native integration.

As a prototype reference, you can rely on the current documentation we have for Amazon GuardDuty: link, which provides a native integration configuration first, followed by a configuration integrating with Kinesis

Task

• Update documentation for Amazon Web Application Firewall (WAF)
