Understanding Wazuh

What is Wazuh?

Wazuh is an open-source security information and event management (SIEM) tool that helps organizations monitor and secure their IT environments. Originally a fork of OSSEC (Open Source Security), Wazuh has evolved into a more advanced and feature-rich platform. It provides real-time visibility into your systems and applications, enabling you to detect, analyze, and respond to security incidents.

Key Features of Wazuh

1. Log Data Analysis: Wazuh collects and analyzes logs from various sources, including servers, firewalls, and applications. It helps in identifying suspicious activities and potential threats through advanced log analysis techniques.
2. Intrusion Detection: The platform uses a combination of signature-based and anomaly-based detection methods to identify potential intrusions. This includes monitoring for unusual patterns in system behavior or unauthorized access attempts.
3. File Integrity Monitoring: Wazuh tracks changes to critical system files and directories. This helps in detecting unauthorized modifications, which could indicate a security breach or malware infection.
4. Vulnerability Detection: The tool scans your systems for known vulnerabilities and provides insights into potential security weaknesses. This feature is crucial for proactive risk management and patch management.
5. Compliance Reporting: Wazuh offers pre-configured compliance rules and reporting templates for various standards such as PCI DSS, HIPAA, and GDPR. This simplifies the process of meeting regulatory requirements and generating compliance reports.
