In the realm of cybersecurity, vigilance is paramount. As an enthusiast managing a home lab, I’ve taken a significant step towards fortifying my network by deploying Wazuh, an open-source Security Information and Event Management (SIEM) and Extended Detection and Response (XDR) tool. This blog explores the intricacies of setting up Wazuh and how it has transformed my approach to home lab security.
Securing Personal Devices and Networks
In a labyrinth of devices and services, each component of my home lab is a potential entry point for threats. By implementing Wazuh, I’ve gained a bird’s-eye view of the activities across my devices, especially those accessing servers and services on different VLANs. NetworkChuck’s detailed tutorial and John Hammond’s insightful walkthrough have been instrumental in helping me tailor Wazuh for comprehensive coverage.
Adhering to NIST 800-53 and STIG
Compliance is not just for large organizations. Applying the Security Technical Implementation Guides (STIGs) and aligning with the NIST 800-53 framework has been a game-changer in hardening my servers. The granular controls and benchmarks have guided me in configuring my systems to ward off intrusions and maintain a resilient defense.
Proactive Vulnerability Assessment
Being proactive rather than reactive is the cornerstone of robust security. Wazuh’s vulnerability detection capabilities continually assess my systems to identify and prioritize software updates and patches. This ongoing vigilance ensures that potential security gaps are addressed promptly, keeping the network fortified against evolving threats.
File Monitoring for Early Indication of Compromise
An often-overlooked aspect of security is the integrity of system and personal files. Wazuh’s file integrity monitoring feature is like an early warning system, signaling alterations that could indicate a compromise. By keeping a watchful eye on critical files, I’ve added an extra layer of security that complements the overall protective measures.
A Practical Guide to Deploying Wazuh in Your Home Lab
Embarking on the journey to enhance my home lab security with Wazuh began with setting up the Wazuh server. Following the specifications from the Wazuh Quickstart documentation, I focused on creating a robust server in vCenter, ensuring it had ample storage and was assigned to the right network. Proper DNS configuration was crucial, directing all my internal domains to this new security hub.
Step-by-Step Installation:
- Server Setup: I first initiated the server in vCenter, adhering closely to the recommended specifications, particularly focusing on storage space to handle the extensive logs and data.
- DNS Configuration: For seamless integration, I configured DNS to resolve my internal domains to the new Wazuh server, ensuring that all traffic would be accurately monitored and analyzed, without opening too many firewall rules.
- I did have to allow the specific ports for the Wazuh Agent to reach back directly to the server.
- Agent Deployment: The Wazuh web UI provides a simple, generated command to install agents on the devices to be monitored. This user-friendly approach allowed me to deploy agents across my devices quickly.
- Data Collection: Within 10 minutes of agent deployment, Wazuh was actively collecting data from my network. It immediately began identifying vulnerabilities and tracking system changes, offering a clear picture of where my security stance stood.
Taking Action:
The data collected was more than just informational; it was actionable. Identifying vulnerable areas allowed me to prioritize security enhancements. With each identified issue, I have begun planning and executing security improvements, steadily fortifying my network and machine’s defenses.
Conclusion:
The process was straightforward, efficient, and highly effective. By following the steps laid out in the Wazuh documentation, reviewing the videos from NetworkChuck and John Hammond, and by utilizing the intuitive web UI, I was able to significantly uplift my home lab’s security posture in a matter of minutes. It’s a testament to the power and user-friendliness of Wazuh as a security tool, making it an invaluable asset for anyone looking to gain insight to their devices and who are serious about their digital defense.
