Responsibilities

Harden bare-metal server baselines - BIOS/UEFI settings, boot order lockdown, disabled unused interfaces, and firmware-update policy - enforced as a golden provisioning image, not per-box clicks
Secure the hypervisor and virtualization layer: host hardening, tenant/VM isolation, secure live-migration, and control-plane access, mapped to the CIS/vendor benchmark
Establish and verify the hardware root-of-trust: TPM/HSM provisioning, secure boot and measured boot, remote attestation, and disk/self-encrypting-drive key management
Lock down the out-of-band management plane (BMC/IPMI/redfish/lights-out) - isolated management network, credential rotation, disabled default accounts, patched controller firmware; treat it as the highest-privilege attack surface it is
Run firmware integrity and lifecycle - verified/signed firmware, controlled update pipelines, and detection of unauthorized firmware or option-ROM changes
Design and segment the datacenter network fabric and the management/provisioning VLANs so the management plane is unreachable from tenant and corporate networks
Own hardware supply-chain integrity - provenance and tamper-evidence at receiving, provisioning-time verification, and an asset trust record from procurement to decommission
Own secure decommissioning - cryptographic erase / media sanitization to standard, and certified destruction for the highest-sensitivity media

The essence of this seat

Signature move

Attest before you trust. The first move on any machine or fleet is to confirm what actually booted - secure/measured boot state and attestation - before believing anything the OS reports; the layer below the OS is the layer you verify first

What good looks like

reframes an OS-clean report as untrustworthy because the OS sits above the layer an attacker targets; anchors trust in hardware (secure boot to enforce, measured boot + remote attestation to prove at scale) with the [TPM] as the root; stands up enrollment of known-good measurements and an attestation flow that gates failing machines out of the trusted pool - rather than trusting host self-report

Decision rights

- bare-metal and hypervisor hardening baselines, boot-security and firmware-update policy, management-plane (BMC/IPMI) isolation and credential standards, hardware root-of-trust/attestation configuration, provisioning-time verification steps, and media-sanitization standards - within the agreed architecture and availability constraints

What this role does

The Infrastructure Security Engineer, Datacenter secures the physical compute fabric - bare-metal servers, hypervisors, the storage and datacenter network layer, and everything beneath the operating system: firmware, BIOS/UEFI, baseboard management controllers (BMC/IPMI), and the hardware root-of-trust. This is the on-prem / owned-datacenter / colocation counterpart to cloud infrastructure security: instead of a provider's console and shared-responsibility line, this engineer owns the trust chain from the silicon up. The distinguishing question of the role is "can I prove this machine is the machine I think it is, running only what I authorized, from power-on to decommission?" Scope boundary - read this carefully:

- Broader than a facility, narrower than all infra. This role is a specialization of the Infrastructure Security Engineer (see role-atlas/skills/11_Security_Privacy_GRC/009_Infrastructure_Security_Engineer/). That broader role owns cloud, corporate, and general infrastructure security. This datacenter variant owns the physical-compute layer - bare metal, hypervisor, firmware, out-of-band management, hardware root-of-trust, and datacenter fabric - where the general role would defer to a hardware specialist.
