Implementing Endpoint Detection with Wazuh
Overview
Wazuh is an open-source SIEM and XDR platform for endpoint monitoring, threat detection, and compliance. This skill covers managing agents via the Wazuh REST API, creating custom decoders and rules in XML for organization-specific detections, querying alerts, and testing rule logic using the logtest endpoint.
Prerequisites
- Wazuh Manager 4.x deployed with API enabled
- Python 3.9+ with
requestslibrary - API credentials (username/password for JWT authentication)
- Understanding of Wazuh decoder and rule XML syntax
Steps
Step 1: Authenticate to Wazuh API
Obtain JWT token via POST to /security/user/authenticate.
Step 2: List and Monitor Agents
Query agent status, versions, and last keep-alive via /agents endpoint.
Step 3: Query Security Alerts
Search alerts by rule ID, severity, agent, or time range.
Step 4: Test Custom Rules with Logtest
Use the /logtest endpoint to validate decoder and rule logic against sample log lines.
Expected Output
JSON report with agent inventory, alert statistics, rule coverage, and logtest validation results.

mapping-mitre-attack-techniques
Maps observed adversary behaviors, security alerts, and detection rules to MITRE ATT&CK techniques and sub-techniques to quantify detection coverage and guide control prioritization. Use when building an ATT&CK-based coverage heatmap, tagging SIEM alerts with technique IDs, aligning security controls to adversary playbooks, or reporting threat exposure to executives. Activates for requests involving ATT&CK Navigator, Sigma rules, MITRE D3FEND, or coverage gap analysis.
