Configuring Wazuh Rules for Vulnerability Scanning with Cis-cat Integration

Wazuh, as an open-source security monitoring platform, can be integrated with vulnerability scanning tools like Cis-cat to enhance vulnerability detection and compliance monitoring. Cis-cat (CIS Configuration Assessment Tool) helps organizations ensure their systems comply with security baselines. By configuring Wazuh rules, security teams can automate the detection of vulnerabilities and misconfigurations identified by Cis-cat, triggering alerts and improving overall incident response.

To integrate Cis-cat vulnerability scanning results into Wazuh, it is crucial to configure Wazuh rules to parse and correlate the findings effectively. This allows for real-time identification of potential security risks across the network, using pre-defined detection rules. Proper configuration ensures that vulnerability findings are correlated with other security data, improving response times and facilitating better management of security incidents.

Steps for Configuring Wazuh Rules

Follow these steps to set up Wazuh rules for Cis-cat vulnerability scanning:

  1. Install and Configure Cis-cat: Ensure Cis-cat is set up and functioning correctly on the target systems. The tool should be capable of generating reports in a format that can be processed by Wazuh, such as JSON or CSV.
  2. Create Custom Wazuh Rules: Develop specific Wazuh rules to match the output from Cis-cat reports. These rules will detect vulnerabilities based on the severity and category of the findings. Customize the rules to map Cis-cat findings with Wazuh's existing rule set.
  3. Test Rule Functionality: After configuring the rules, run tests to ensure that the integration is effective. Simulate vulnerabilities and verify that Wazuh triggers the appropriate alerts based on Cis-cat findings.

Key Configuration Considerations

  • Rule Severity Mapping: Map the Cis-cat severity levels (e.g., critical, high, medium, low) to the corresponding Wazuh rule severity levels. This ensures that critical vulnerabilities are prioritized for immediate attention.
  • Alert Customization: Customize Wazuh alerts to include relevant information from Cis-cat reports, such as affected systems, vulnerability descriptions, and remediation steps.
  • Integration with Other Tools: Ensure that Wazuh is integrated with other security tools like SIEM or ticketing systems for streamlined incident response.

Important: Always test the rule configuration on a non-production environment before deploying to ensure no false positives or missed detections occur.

Sample Wazuh Rule Configuration for Cis-cat

Below is an example of a basic Wazuh rule to detect vulnerabilities reported by Cis-cat:

Rule ID Event Type Severity Level Description
100100 cis-cat_vulnerability High Critical vulnerability detected in system configuration
100101 cis-cat_vulnerability Medium Medium-level vulnerability detected

Monitoring CIS-CAT Scan Results in Wazuh Dashboard

Integrating CIS-CAT scan results into Wazuh enables users to efficiently monitor and analyze compliance data. Wazuh's powerful dashboard can process and visualize the results of CIS-CAT scans, providing a centralized view of the security posture across multiple systems. By leveraging this integration, security professionals can track compliance over time, identify vulnerabilities, and take proactive measures to mitigate risks.

To monitor the CIS-CAT results in Wazuh, the integration involves collecting scan output and ingesting it into the Wazuh platform. This process ensures that security teams can gain insights into system configurations and alignment with security benchmarks directly from the Wazuh dashboard.

Steps to View CIS-CAT Results in Wazuh Dashboard

  • Set up the integration between CIS-CAT and Wazuh using the Wazuh agent on your systems.
  • Configure the Wazuh manager to receive and process the scan data from CIS-CAT.
  • View the processed results directly in the Wazuh dashboard, where compliance findings are categorized for easy review.

Once the CIS-CAT results are ingested, the Wazuh dashboard displays detailed compliance information in an organized manner. The results include the following components:

Category Status Severity
Operating System Security Compliant Low
Network Configuration Non-Compliant High
Application Security Compliant Medium

Important: The Wazuh dashboard allows filtering and sorting compliance data to focus on critical vulnerabilities and track remediation efforts effectively.

Visualizing and Acting on Results

  1. Use the Wazuh alerts and visualizations to prioritize issues based on their severity.
  2. Generate compliance reports to document the security status and guide future audits.
  3. Take immediate actions on non-compliant items directly from the Wazuh interface.

Customizing CIS-CAT Alerts in Wazuh

When integrating the CIS-CAT (CIS Configuration Assessment Tool) with Wazuh, fine-tuning the alerting system is essential for efficiently monitoring and responding to security findings. By customizing how alerts are generated and presented, security teams can ensure they focus on high-priority issues while minimizing noise from irrelevant events. This customization process can be achieved by modifying alert rules, adjusting severity levels, and configuring specific thresholds that align with the organization's security posture.

Wazuh provides a robust set of capabilities for managing and fine-tuning alerts. One of the key strategies is adjusting the rules for CIS-CAT findings, allowing security teams to streamline alerting based on specific use cases and compliance requirements. Below are several practical ways to customize the alert system:

Key Customization Techniques

  • Modifying Rule Sets: Create or modify existing rule sets to categorize alerts by severity and type, ensuring that critical findings are highlighted.
  • Threshold Adjustments: Set thresholds for triggering alerts based on specific CIS-CAT benchmarks. For example, limit the number of warnings before generating a critical alert.
  • Alert Suppression: Use suppression filters to ignore repetitive or less important findings that do not require immediate attention.

To effectively implement these adjustments, teams need to work within the Wazuh rule configuration files. For example, the cis-cat.rules file can be tailored to set custom alert thresholds, severity levels, and other parameters. Here is an example configuration for triggering alerts on specific benchmarks:

Parameter Description
Rule ID Unique identifier for the CIS-CAT related alert rule.
Alert Severity Defines the urgency of the alert (e.g., Low, Medium, High).
Threshold The limit of findings or severity that triggers the alert.

Customizing CIS-CAT alerts ensures that security teams only receive relevant, actionable notifications, reducing alert fatigue and focusing efforts on critical issues.

Advanced Alert Filtering

  1. Identify critical CIS-CAT checks that need immediate attention and assign them a higher severity in Wazuh.
  2. Implement event aggregation to combine similar findings into a single alert, preventing duplicate notifications.
  3. Enable specific log sources to be monitored more closely for certain compliance checks, tailoring alert configurations accordingly.

Automating Cis-cat Reporting in Wazuh

Automating the integration of Cis-cat reports with Wazuh can significantly streamline security audits and compliance checks. By integrating Cis-cat scans with the Wazuh monitoring platform, organizations can automatically generate security compliance reports and take immediate action based on the findings. This process reduces the need for manual intervention, ensuring more consistent and accurate assessments.

The key to effective automation lies in properly configuring both Cis-cat and Wazuh to work in tandem. Once set up, automated tasks can provide real-time alerts, improve incident response times, and simplify overall compliance management. Below is an outline of the core steps and important elements to consider when automating the Cis-cat reporting process in Wazuh.

Steps to Automate Cis-cat Reporting in Wazuh

  1. Install and Configure Cis-cat - Ensure that the Cis-cat tool is installed and configured according to the organization's security baseline requirements.
