• Maintain configuration baselines, security documentation, and evidence for compliance reviews.
• Implement and maintain system hardening standards and security controls across Linux and hybrid environments.

Monitoring, Logging & Incident Response

• Deploy and manage system monitoring tools (Prometheus, Grafana, Nagios, Zabbix).
• Maintain centralized logging (e.g., syslog, ELK/Elastic) in accordance with NIST audit and traceability requirements.
• Support incident response activities, root-cause analysis, and corrective actions.
• Contribute to continuous improvement of detection, response, and recovery processes.

Networking & Interoperability

• Troubleshoot networking services, secure remote access, firewall rules, VPN configurations, and cross-platform connectivity.
• Ensure secure communication between Linux systems and Windows infrastructure components.

DevOps & Automation (Preferred)

• Use automation tools (Ansible, Terraform, scripting) to support consistent, compliant system deployments.
• Assist with CI/CD pipeline integrations in regulated environments.

Documentation & Collaboration

• Maintain detailed runbooks, diagrams, SOPs, and configuration documentation aligned with compliance standards.
• Work closely with IT, security, engineering, and compliance teams to ensure seamless operations across controlled environments.

REQUIRED SKILLS / EXPERIENCE
