This post presents Wazuh CLI, an open-source command-line tool that simplifies managing and automating Wazuh SIEM/XDR operations for cybersecurity monitoring and incident response.
OpenCTI can expose shared data through different native feeds, including Live streams, TAXII collections, and CSV feeds. For this integration, I chose a TAXII collection because it exposes STIX 2.1 bundles through a standard API and provides a pagination model that is straightforward to automate.
By connecting Wazuh to Claude Desktop using MCP (Model Context Protocol), you can talk to your SIEM like you’d talk to a colleague. No complex queries. No dashboard hopping. Just ask, and get answers.
By the end of this walkthrough, you will learn how to deploy Sysmon using an industry-standard configuration, forward Sysmon telemetry into Wazuh, create custom detection rules for persistence and process injection, and validate detections using simulated attack activity.
A common mistake in monitoring design is collecting too many metrics without understanding their purpose. More data does not mean better monitoring. It often means more noise. Effective monitoring focuses on a small number of high-value signals that clearly indicate when something is wrong.
One week after Copy Fail (CVE-2026-31431), V4bel dropped Dirty Frag – CVE-2026-43284 and CVE-2026-43500. Same authencesn decrypt sink. Completely different code path.
How we unified security monitoring and infrastructure observability into a single pane of glass – without replacing a single tool.
Wazuh is highly customizable, which allows us to build our own case management and remote command capabilities without requiring any additional agents.
