Modern hardware supply chains are multi-layered and globalized, involving numerous suppliers, manufacturers, and logistics vendors. For instance, each of the design, raw material sourcing, manufacturing, and assembly stages of a single piece of hardware can take place in a different country. The nature of modern supply chains makes them increasingly vulnerable to a wide range of cyberthreats, which can disrupt the integrity and availability of critical hardware.
The increased risk of cyberattacks on supply chains requires the implementation of strict cybersecurity regulations. Developing, enforcing, and ensuring compliance with security regulations comes with significant challenges and requires extensive collaboration between governments and industry stakeholders.
Understanding the Hardware Supply Chain Risks
The hardware supply chain is difficult to secure due to the number of layers and organizations involved. The unavoidable reliance on global suppliers increases the exposure to vulnerabilities, particularly when components are sourced from regions with low cybersecurity or regulatory controls.
Cybersecurity Threats in Hardware Supply Chains
The impact of cyberattacks on hardware supply chains can lead to critical data breaches, operational disruptions, and financial losses. Even in the event of a cyberattack causing little to no damage, exploiting such vulnerabilities can still lead to a loss of trust and damage market confidence.
Adversaries can employ various methods to exploit vulnerabilities in hardware supply chains:
- Hardware Backdoors: Used to gain unauthorized access and can be implanted within hardware components
- Counterfeit Hardware: Can be difficult to distinguish from legitimate products with performance issues and security vulnerabilities
- Software Vulnerabilities Exploitation: Could be firmware or software vulnerabilities that grant unauthorized access
- Supply Chain Interception: Gaining physical access to shipments enables adversaries to modify the hardware
Regulatory Compliance Challenges
Regulatory compliance ensures mitigating various risks besides legal penalties, such as loss of market access and reputational damage. Hardware supply chains span across multiple jurisdictions that impose complex regulatory requirements, bringing various challenges to maintaining compliance.
Some of the common regulatory frameworks are the U.S. Cybersecurity Executive Order (EO 14028), National Institute of Standards and Technology (NIST) framework, and European Union Cyber Resilience Act (CRA).
Key Components of Hardware Supply Chain Security
Access Control and Monitoring
Ensuring that only authorized entities gain access to critical components and systems requires implementing various effective strategies and technologies:
- RBAC (Role-Based Access Control): To minimize the risk of unauthorized modifications
- MFA (Multi-Factor Authentication): Adds a new layer of security to prevent unauthorized access
- Hardware Authentication: By utilizing cryptographic methods, such as Trusted Platform Modules (TPM)
- Zero Trust Security Model: To enable granular access and enforce continuous verification
- Physical Security Measures: Such as biometric authentication and surveillance systems
Threat Intelligence
Threat intelligence enables organizations to predict and identify emerging threats, proactively mitigate risks, and enhance decision-making. Leveraging real-time data and predictive analytics contributes to identifying potential risks before they impact the supply chain. SIEM (Security Information and Event Management) systems, TIPs (Threat Intelligence Platforms), AI and machine learning, and dark web monitoring are some of the technologies and practices that can be employed within hardware supply chains to enhance threat intelligence.
Implementing a Zero Trust Security Model
Zero Trust is a modern cybersecurity approach that offers more adaptability to the complexities of modern technology environments. ZTNA (zero trust network access) is a solution designed to address traditional VPN networks' performance issues and limitations, and reduce the attack surface in case of a breach.
Principles of Zero Trust
Zero Trust is built on three main principles:
- Verify Explicitly: Always authenticate users, devices, and applications.
- Principle of Least Privilege: Restrict access to the necessary level.
- Assume Breach Mentality: Expect that a breach will occur, implementing mitigation and response strategies.
Zero Trust in Practice
Some key applications of Zero Trust include implementing access controls and continuous monitoring for external suppliers, performing regular data encryption and integrity checks, and enforcing MFA with least privilege access.
Adopting Zero Trust networks in hardware supply chain environments can be challenging, especially with the presence of multiple suppliers and with the existence of deployed legacy systems. It also requires considerable costs since the initial deployment can be resource intensive.
The Role of Trusted Computing in Supply Chain Security
Trusted Computing employs cryptographic techniques to enhance the integrity and security of computing systems. Methods like TPMs (Trusted Platform Modules) and secure boot processes ensure that only verified and authorized software runs on a system.
Trusted Platform Module (TPM)
A TPM is a specialized hardware security chip designed to provide cryptographic functions to enhance the security of computing devices. Utilizing TPMs helps secure hardware components by generating and managing cryptographic keys to prevent unauthorized access, verifying platform integrity at boot time, and full-data encryption. It can also enable remote verification of a device’s trustworthiness.
TPM technology can be included within applications in the hardware supply chain, such as component authentication, tamper detection, and firmware protection.
Secure Boot Processes
Secure Boot mechanism prevents unauthorized software from being executed during system startup by verifying the encrypted digital signatures of firmware and system bootloaders. Such a mechanism helps prevent rootkit and bootkit malware infections.
Implementing Secure Boot enhances hardware supply chain security by ensuring components' authenticity throughout transportation and deployment. Secure Boot can be used along with TPM to provide multi-layered hardware security.
Best Practices for Securing the Hardware Supply Chain
Securing the modern, multi-layered hardware supply chain requires incorporating multiple approaches and strategies to integrate cybersecurity best practices with physical security controls.
Actionable Security Steps
- Supplier risk assessment
- Regular firmware and software integrity checks
- Zero Trust security model implementation
- Strict physical security for the manufacturing processes
- Threat intelligence sharing
- Regular employee cybersecurity awareness training
Such actionable steps may not be enough. Performing regular security audits is essential to maintain the integrity and security of hardware supply chains, ensure adherence to the latest industry regulations, help address vulnerabilities before they can be exploited by malicious actors, and regularly assess third-party vendors’ security measures.
Collaboration and Partnerships
With the increase in cyberthreat complexities, collaboration between industry stakeholders, government agencies, and cybersecurity experts is necessary. Effective partnerships bring significant benefits, such as knowledge sharing to stay ahead of emerging threats, standardizing security practices, and implementing rapid incident response measures. To support such partnerships, ISACs (Information Sharing and Analysis Centers) were formed to facilitate collaboration between the private sector and the U.S. government for threat intelligence sharing.
Future Trends in Hardware Supply Chain Security
AI and Machine Learning
AI applications are increasingly integrated within the operations of many industries. For hardware supply chains, adopting AI and machine learning applications can enhance threat detection with real-time anomaly detection, AI-driven threat prediction, and automated incident responses. They can also improve supplier risk analysis by evaluating specific suppliers’ security practices and identifying weaknesses within their supply chains.
Blockchain and Internet of Things (IoT)
Blockchain technology adds to the supply chain transparency by ensuring secure, immutable records of transactions. The emerging decentralized blockchain applications help prevent unauthorized modifications to the supply chain records and improve record traceability.
The use of IoT devices, such as GPS trackers and RFID Tags, in supply chains enhances performance and productivity. However, these devices introduce security risks that must be addressed. For instance, unpatched firmware vulnerabilities and unsecured endpoints are some of the common attack pathways for IoT devices. Blockchain-enabled IoT devices can overcome many security challenges by adding transparency to verify device identities and maintain data integrity.
