Hi Jaymin Trivedi,

Unfortunately, there's no direct, out-of-the-box integration between Wazuh and Threat Intelligence TAXII servers

The Wazuh Integrator module allows you to connect Wazuh to external APIs, including fetching data from external threat intelligence sources. You can follow the general process outlined in this document. After integrating the TAXII server, you’ll need to configure decoders, rules, and alerts to leverage the fetched threat intelligence data within Wazuh.

Additionally Wazuh’s MITRE ATT&CK module provides built-in threat intelligence capabilities, offering valuable context on alerts in your environment  For more details, refer to Wazuh's documentation on threat intelligence. Wazuh also leverages its XDR capabilities to identify and store Indicators of Compromise (IoCs) detected in your infrastructure, focusing on atomic and computed IoCs such as IP addresses, URLs, and file hashes.and this blog post on building IoC files.

Hope this helps

Integrating a Threat Intelligence TAXII (Trusted Automated Exchange of Indicator Information) server with Wazuh can enhance your security monitoring by allowing Wazuh to consume and use threat intelligence data for detecting known threats. Here’s a step-by-step guide on how to integrate a TAXII server with Wazuh:

Step 1: Set Up and Configure the TAXII Server

Before integrating with Wazuh, ensure that your TAXII server is up and running. If you don’t have one, you can use open-source TAXII servers like Cabby or commercial solutions.

Step 2: Install and Configure taxii2client

Wazuh uses the taxii2client Python library to interact with TAXII servers. You need to install this on the Wazuh manager.

1. Install Python 3 and pip (if not already installed):

2. sudo apt-get update
   sudo apt-get install python3 python3-pip
   

3. sudo pip3 install taxii2-client
   

Step 3: Create a TAXII Feed Configuration in Wazuh

You need to configure Wazuh to pull threat intelligence data from the TAXII server.

1. Create the TAXII feed script:

   Create a script that Wazuh can use to fetch the data. For example, create a script named fetch_taxii.py:

#!/usr/bin/env python3
from taxii2client.v20 import Server
import requests
import sys

TAXII_SERVER = "https://your-taxii-server-url"
COLLECTION = "your-collection-name"
USERNAME = "your-username"
PASSWORD = "your-password"

server = Server(TAXII_SERVER, user=USERNAME, password=PASSWORD)
api_root = server.api_roots[0]
collection = api_root.collections[COLLECTION]

for obj in collection.get_objects():
    print(obj.serialize())

• Replace TAXII_SERVER, COLLECTION, USERNAME, and PASSWORD with your actual TAXII server details.

• Make the script executable:

chmod +x fetch_taxii.py

Step 4: Configure Wazuh to Use the TAXII Feed

Wazuh needs to be set up to use the data fetched from the TAXII server.

1. Modify Wazuh's custom rules or decoders:

   • Use the fetched indicators in your custom rules or decoders. For example, you can create rules that match IP addresses, domains, or hashes against the intelligence data.

2. Schedule the TAXII feed script:

• Use cron to regularly fetch data from the TAXII server:
• crontab -e
  
3. Add a line to run the script, for example, daily:
   
4. 0 0 * * * /path/to/fetch_taxii.py > /var/ossec/etc/lists/indicator_list.txt
   

1. This will save the fetched indicators to a file that Wazuh can use in its detection rules.

Step 5: Test the Integration

• After configuring everything, test the integration by running the script manually to ensure it pulls data from the TAXII server.
• Ensure Wazuh is correctly using the fetched data by checking the Wazuh logs and alerts.

Step 6: Monitor and Fine-Tune

• Continuously monitor the alerts generated by Wazuh using the threat intelligence data. Adjust your rules and scripts as needed to improve detection accuracy.

Optional: Integrate with Kibana

If you are using the Wazuh app in Kibana, you can visualize and manage the indicators pulled from the TAXII server within the Wazuh interface.
