Introduction
Wazuh is an open source security monitoring application that provides threat detection, file integrity monitoring, log management and vulnerability assessment capabilities. It allows security administrators and beginners to gain comprehensive visibility into their systems and protect themselves against evolving cyber threats. In this blog post, we will explore how Wazuh provides an easy to use yet powerful solution for beginners to implement security monitoring with minimal effort.
What is Wazuh?
Wazuh is an intrusion detection system that leverages the shared intelligence of the open source community to protect teams against known and unknown threats. It was originally founded in 2015 by researchers and developers at Panda Security and is now maintained by a large open source community.
Wazuh utilizes the Elastic Stack for log collection, analysis, search and visualization. It collects security events from operating systems, network devices, applications and custom sources to monitor your IT infrastructure for anomalies and threats. Some key features of Wazuh include:
| Key Feature | Description |
| Log Monitoring | Collects and analyzes logs to detect anomalies and threats |
| File Integrity Monitoring | Monitors files for unauthorized changes across systems |
| Vulnerability Assessment | Detects vulnerabilities from archives like CVE and OSVDB |
| Rule Engine | Leverages a rule system to define custom detection rules |
| Decentralized Architecture | Agents run locally on clients and report to a centralized manager |
With these capabilities, beginners can easily implement security event monitoring and get visibility into their environments with minimal security expertise.
Why Use Wazuh for Beginners?
It's Free and Open Source
Wazuh is completely free to download and use, with no licensing costs. This removes one of the largest barriers to trying a new security tool, ideal for beginners just starting their security journey.
Simple User Interface
The Wazuh web interface provides an easy to navigate dashboard and investigative screens. It hides the complexities of backend technologies like Elastic Stack so beginners can start analyzing security events quickly.
Out-of-the-Box Integrations
Wazuh ships with common integrations to technologies like Windows, Linux, Filebeat and syslog out of the box. This means beginners can have basic monitoring up and running with minimal configuration.
Active Community Support
Being an open source project, Wazuh has excellent community support across multiple channels like forums, Slack, GitHub and more. Beginners can readily get help to resolve issues as they learn.
Key Capabilities for Beginners
Some of the main security capabilities Wazuh provides right out of the box to help beginners are:
Log Monitoring
Collects logs from endpoints and aggregates them in a central location for analysis and search. This provides visibility into activity across all systems.
File Integrity Monitoring
Monitors critical system files, directories and registry keys for unauthorized changes on Windows/Linux. This allows detection of intrusions via malware or hackers modifying system files.
Vulnerability Detection
Leverages vulnerability databases to monitor endpoints for known vulnerabilities like those in CVE, OSVDB or other lists. Beginners gain awareness of exposure in their environments.
Active Response
Wazuh allows configuring simple active responses to detected threats like sending emails or running custom scripts. This enables beginners to take automatic mitigating actions.
Geo-location of Assets
The IP addresses detected can be geo-located to identify anomalous logins from distant locations which could indicate compromised credentials. This adds spatial context for beginners during investigations.
Easy Installation and Setup
Installing and configuring Wazuh from scratch requires only a few basic steps and is quite straightforward for beginners to achieve.
Downloading and Installation
Wazuh packages are available for common Linux distributions via repositories or official downloads. Installation only requires a few commands and takes 5-10 minutes.
Configuration
Configuring Wazuh involves editing configuration files to define basic settings like locations, lists, email addresses etc. Example configuration files are provided to get started quickly.
Onboarding Agents
Agents can be installed on individual systems via packages or scripts. They automatically register and start sending events to the central manager node.
Verifying Setup
Beginners can use the wazuh-ctl command to check the manager and verify agents are connected and operational from the CLI before logging into the web interface.
Screenshots and code samples are available in the GitHub repository to help beginners with specific installation and configuration steps.
Using the Wazuh Web User Interface
Once installed, beginners can access the Wazuh web user interface on port 5601 to start analyzing security events. Here are some key things they can do:
Dashboard
The dashboard provides visual insights into top attacks, vulnerabilities found, agent status and other metrics. This helps prioritize investigations.
Events
The events page lists all recent logs, alerts and compliance checks. Filters, searches and drill downs allow isolating specific events for inspection.
Groups of Agents
Beginners can create logical groups to monitor like critical assets, databases, developer machines etc separately for focused analysis.
Rule Monitoring
Specific Wazuh rules being triggered provide details on exact threats, anomalies or policy violations detected on each agent.
Alerts
A snapshot of active and recently mitigated alerts highlights ongoing and resolved issues across all monitored assets.
Reports
Pre-built compliance, vulnerability and system inventory reports give a one-stop view of security posture without complex configuration.
Screenshots and examples in the GitHub repository help novice Wazuh users learn how to effectively leverage the interface for their security monitoring needs.
Additional Tips for Beginners
As beginners gain more experience with Wazuh, some additional recommendations include:
Integrating Wazuh with SIEMs like Splunk or ELK for centralized alerting and reporting
Configuring active responses to automate security controls
Using Rules editor to define custom detections for unique environments
Automating agent deployment via Ansible, Puppet or similar tools
Browsing documentation, videos and forums for continual skills enhancement
Considering Wazuh trial for more enterprise features like Redshift, SCA and DPA
Community Slack and GitHub are also excellent resources for collaborating with other Wazuh users and experts to improve security program with open source intelligence as skills progress.
