• Procure, configure, and manage networking equipment (routers, switches, firewalls, wireless access points) and IoT / OT devices used for security research and exploit validation.
• Manage lab network architecture — including segmentation, VLANs, out-of-band management, and isolated test environments to safely run exploit code against live devices.
• Administer Linux and Windows servers, hypervisors, and virtualization platforms (e.g., VMware, Proxmox, KVM) that host vulnerable software and services for testing.
• Maintain firmware libraries and device inventories, ensuring researchers have access to specific hardware and software versions needed for vulnerability analysis.
• Provide remote access infrastructure (VPN, jump hosts, remote console access) so distributed team members can interact with physical lab equipment.
• Automate environment provisioning, configuration management, and lab reset workflows using tools such as Ansible, Terraform, or similar.
• Monitor lab systems for availability, performance, and security — and respond to issues promptly.
