Wazuh SIEM System Administrator
& Associate System Administrator / System Software Engineer
JOB SUMMARY
IDRBT is seeking dedicated Wazuh SIEM Administrators and System Software Engineers to manage the complete Wazuh SIEM system lifecycle — from planning and execution through to ongoing maintenance. The team will monitor system performance, build tools that maximise the open-source SIEM/XDR platform, and own end-to-end Wazuh server cluster deployment, agent onboarding, and fine-grained Role-Based Access Control (RBAC) implementation to ensure secure, least-privilege operations for security teams and auditors.
ROLE OVERVIEW
| Experience | Department | Location | Employment Type |
|---|---|---|---|
| 1 – 7 Years | Cybersecurity / SOC | On-Site | Full-Time |
KEY RESPONSIBILITIES
Wazuh Infrastructure & Setup
- Deploy and maintain high-availability Wazuh central components: Wazuh server, Wazuh indexer, and Wazuh dashboard.
- Streamline deployment and remote management of Wazuh agents across Windows, Linux, and macOS endpoints using Ansible.
- Monitor on-premises Nutanix Acropolis (AHV) private cloud — track infrastructure health, hypervisor performance, and storage metrics simultaneously.
- Core Metrics to Track:
- Storage IOPS & Latency: maintain storage pool and container latencies below 10–15 ms.
- CPU / Memory Overcommit: track cluster provisioning ratios to prevent host contention.
- CVM Health: monitor Controller VM (CVM) memory, CPU usage, and cluster replication status.
- Storage Capacity: predict storage runway to avoid metadata or disk exhaustion.
- Configure agent groups and enrollment settings to ensure centralised management and log collection.
Role-Based Access Control (RBAC) & User Management
- Architect and implement fine-grained RBAC in Wazuh to restrict dashboard access, API utilisation, and incident management actions based on user roles (e.g., Security Analyst vs. Security Engineer).
- Configure internal users and define security policies, roles, and rulesets tailored to organisational hierarchy.
- Integrate Wazuh dashboard with enterprise Identity Providers (IdPs) via SAML/OIDC (e.g., Microsoft Entra ID).
- Configure Active Directory / LDAP for unified authentication and authorisation across the platform.
Monitoring & Security Operations
- Configure custom decoders, rules, and active responses for proactive threat detection and automated remediation.
- Enforce strict File Integrity Monitoring (FIM) across critical endpoints and servers.
- Implement and maintain Vulnerability Detection pipelines to surface and track CVEs across the estate.
- Conduct and schedule Security Configuration Assessments (SCA) to continuously validate hardening baselines.
- Track the full Wazuh SIEM system lifecycle — from planning through execution and maintenance — and produce regular performance and health reports.
