Slack Integration Wazuh Server : Alerts in Critical, High, and Medium Slack Channels

1. Set Up a Slack App:

  • Go to the Slack API website and log in to your workspace.
  • Navigate to “Your Apps” and click on “Create New App.”
  • Enter a name for your app (e.g., “Wazuh Alerts”) and select the workspace where you want to install the app.
  • Create three channels named “Critical”, “High” and “Medium”.
  • In the app settings, go to “Incoming Webhooks” and enable it.
  • Click on “Add New Webhook to Workspace” to generate a webhook URL. Note down this URL for the three channels, as you’ll need it later.

https://api.slack.com/apps

 

Edit Wazuh Configuration File:

  • Edit /var/ossec/etc/ossec.conf in the Wazuh server and include a configuration block such as the following.

<integration>
<name>slack</name>
<hook_url>https://hooks.slack.com/services/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</hook_url>
<alert_format>json</alert_format>
</integration>

 

 

Replace WEBHOOK_URL with your Incoming Webhook URL for the three channels appropriately

Restart Wazuh Services:

sudo systemctl restart wazuh-manager
