Wazuh, an open-source security platform, has been a reliable tool for monitoring and securing IT infrastructures. With its latest version 4.11, Wazuh has introduced significant improvements in its vulnerability management module, prioritizing vulnerabilities listed by the CISA over those from the NVD. This shift aims to reduce the risk of false positives, thereby enhancing the overall security posture.
Key Features of Wazuh 4.11:
- Prioritization of CISA Vulnerabilities: Wazuh now prioritizes vulnerabilities listed by the Cybersecurity and Infrastructure Security Agency (CISA), which are often more critical and actionable.
- Reduced False Positives: By focusing on CISA’s Known Exploited Vulnerabilities (KEV) catalog, Wazuh minimizes the occurrence of false positives, allowing security teams to concentrate on genuine threats.
- Comprehensive Monitoring: Wazuh provides continuous monitoring of endpoints, cloud environments, and containers, ensuring a holistic security approach.
Practical Implementation:
To get started with Wazuh, follow these steps:
1. Installation:
curl -sO https://packages.wazuh.com/4.x/wazuh-install.sh && sudo bash ./wazuh-install.sh -a
2. Configuration:
Edit the Wazuh configuration file to enable vulnerability detection:
sudo nano /var/ossec/etc/ossec.conf
Add the following lines:
<vulnerability-detector> <enabled>yes</enabled> <interval>5m</interval> <ignore_time>6h</ignore_time> <run_on_start>yes</run_on_start> </vulnerability-detector>
3. Starting Wazuh:
sudo systemctl start wazuh-manager sudo systemctl enable wazuh-manager
4. Monitoring Logs:
Use the following command to monitor Wazuh logs in real-time:
tail -f /var/ossec/logs/alerts/alerts.log
