Description

This curriculum spans the full lifecycle of hardware security within an ISO 27001 framework, comparable in depth to a multi-phase internal capability program that integrates risk assessment, supply chain oversight, configuration management, and incident response across enterprise infrastructure.

Installing tamper-evident seals on critical hardware enclosures and defining inspection frequency.
Deploying environmental monitoring systems to detect conditions that could damage hardware (e.g., overheating, humidity).
Implementing video surveillance with retention policies aligned with incident investigation needs.
Defining procedures for secure hardware movement within and between facilities.
Requiring dual custody for accessing high-security hardware such as HSMs or cryptographic key generators.
Establishing visitor access protocols that prevent unsupervised physical interaction with hardware.
Coordinating with facilities management to ensure secure disposal of hardware waste (e.g., locked bins, shredding).

Module 6: Hardware-Based Cryptographic Controls and Key Management

Selecting Hardware Security Modules (HSMs) based on FIPS 140-2/3 validation levels and integration requirements.

Integrating HSMs with PKI systems for secure certificate issuance and key storage.
Implementing key backup and recovery procedures that maintain confidentiality and availability.
Establishing key rotation schedules based on algorithm strength and usage context.
Using TPMs to bind encryption keys to specific hardware states and prevent key extraction.
Documenting key custodianship and transfer procedures for audit and continuity.
Deciding between centralized and distributed key management architectures based on operational resilience needs.

Module 7: Endpoint Hardware Security for Mobile and Remote Devices

Requiring TPM 2.0 and secure boot on all corporate-issued laptops and mobile devices.
Configuring self-encrypting drives (SEDs) with centralized key management integration.

Creating correlation rules to detect anomalies such as unexpected firmware changes or boot failures.
Deploying network-based detection systems to identify rogue hardware (e.g., unauthorized access points).
Using endpoint detection and response (EDR) tools to monitor for hardware exploitation attempts.
Establishing thresholds for physical access attempts that trigger alerts or lockouts.
Conducting regular hardware integrity attestation across the device fleet.
