In May 2023, the United States encountered a significant cyber-espionage campaign executed by a Chinese hacking group within the U.S. territory of Guam. This campaign compromised critical communication and transportation infrastructure, sparking concerns about potential risks to the Department of Defense’s (DOD) logistics system. The United States is now faced with the urgent need to reinforce the security of its digital logistics to ensure the uninterrupted operation of critical services, including humanitarian aid, disaster relief, and military missions.
The Current State of DOD Logistics: The Department of Defense relies on a complex network of systems and subsystems to manage its supply chain and logistical operations. These systems encompass various data elements, facilitating the movement of goods and services, managing inventory, placing orders, and tracking shipments. However, the existence of multiple enterprise resource planning (ERP) systems across different military departments and services poses a significant vulnerability. These systems operate independently, inhibiting communication and coordination, which is crucial during operations.
The Cybersecurity Challenge: The use of multiple systems amplifies the cyber threat landscape. The absence of a unified ERP system results in stove-piped data silos that cannot efficiently communicate, impairing visibility and complicating the ordering process. Information is transmitted over non-classified networks, exposing vulnerabilities that adversaries can exploit. Understanding these challenges is vital in mitigating risks and adhering to Supply Chain Risk Management guidelines outlined in DODI 5200.44, “Protection of Mission Critical Functions to Achieve Trusted Systems and Networks (TSN).”
China’s Approach: In contrast, China has unified its military logistics under the Joint Logistics Support Force (JLSF), streamlining medical services, transportation, and supply functions. China’s National Public Information Platform for Transportation and Logistics (LOGINK) serves as a global data platform, offering shipment tracking and data management services. This platform, recognized internationally in 2022, provides a wealth of data on cargo movements, posing challenges and concerns regarding its potential access by China.
Vulnerabilities and Threats: The DOD’s logistical capabilities, relying heavily on digital data transmitted through NIPRNet, are susceptible to attacks. Past incidents, such as the 2012 and 2013 breaches of U.S. Transportation Command’s systems and the 2021 cyberattack on the Colonial Pipeline, demonstrate the seriousness of the threat landscape. In May 2023, a state-sponsored hacking group from China penetrated telecommunications and transportation hubs in Guam, highlighting the potential for severe disruptions during crises.
Securing the Digital Line of Communication: To safeguard the future of DOD logistics, it is imperative to address the inherent vulnerabilities. Measures such as access control, data loss prevention, and data encryption are essential. Access control ensures that only authorized users access sensitive data, and data loss prevention mechanisms prevent unauthorized data disclosure. Encryption protects data in storage and during transmission, maintaining its confidentiality.
Leveraging Innovative Technologies: To enhance security, the DOD must adopt innovative technologies, including artificial intelligence (AI), machine learning (ML), and distributed ledger technology (DLT) using blockchain or directed acyclic graph (DAG) transactions. AI and ML can automate threat detection, analyze historical data, predict future trends, and enhance situational awareness. They are vital in addressing emerging threats and improving decision-making processes.
The Zero Trust Cybersecurity Strategy: The DOD is embracing the Zero Trust Cybersecurity Strategy, characterized by “never trust, always verify.” This approach minimizes access and pathways, strictly controlling data access. AI and ML play pivotal roles in monitoring and identifying abnormal user behavior, enhancing security measures.
A Holistic Approach to Securing Logistics: AI and ML technologies provide an edge in recognizing patterns, anomalies, and potential threats, thus enabling swift and effective responses. Implementing these technologies within the supply chain demands careful planning, robust data governance, and thorough personnel training.
In the face of increasing cybersecurity challenges, the DOD must prioritize securing its digital logistics to ensure the continuity of its vital operations and protect against potential disruptions. A comprehensive approach to addressing vulnerabilities, combined with innovative technologies, will be crucial in maintaining the integrity of the Department of Defense’s logistical operations.
Distributed Ledger Technology (DLT): Distributed Ledger Technology (DLT) is a system designed to record transactions and track assets in a secure and immutable manner. It relies on a shared and synchronized database across multiple computers and locations, providing redundancy and data interoperability. DLT is versatile and can be used for various purposes, including tracking financial transactions, recording property ownership, and managing supply chains. Large corporations, such as Alphabet and Walmart, have adopted this technology, which offers a secure and transparent way to record and track data.
Two Types of DLT: DLT comes in two main types: permissionless and permissioned. Permissionless DLT is open to anyone, with no central authority controlling the network. Bitcoin is an example of an open, decentralized DLT. Permissioned DLT, on the other hand, is controlled by a single entity, with all participants agreeing to network terms. De Beers’ “Tracr” is an example of permissioned DLT.
Advantages and Challenges of DLT: Both permissionless and permissioned DLT have their advantages and disadvantages. Permissionless DLT is secure and transparent but can be challenging to scale, while permissioned DLT is easier to scale but less secure and transparent. The choice between them depends on specific application needs.
DLT’s Benefits: DLT offers several advantages, including increased security, reduced costs by eliminating intermediaries, improved efficiency through automation, enhanced transparency, and the ability to add layers, such as AI, 3D mapping, and the Internet of Things (IoT). These benefits make DLT a valuable tool in securing logistical data.
Challenges: DLT also presents challenges, including scalability, evolving legal and regulatory environments, susceptibility to security attacks, and interoperability issues between DLT systems. These challenges require careful consideration when implementing DLT solutions.
Blockchain and Directed Acyclic Graph (DAG) Technology: Two key technologies within DLT are blockchain and directed acyclic graph (DAG). These technologies differ in structure, consensus mechanisms, scalability, and security. Blockchain uses a linear structure, where data is stored in blocks linked chronologically. In contrast, DAG is non-linear and organizes transactions as a directed acyclic graph.
Consensus Mechanisms: Blockchain and DAG utilize different consensus mechanisms. Blockchain relies on proof-of-work and proof-of-stake, where miners solve complex mathematical problems or own native coins to validate blocks. DAG achieves consensus through a voting system by nodes, where each transaction verifies two previous transactions.
Scalability and Security: Scalability is a key challenge for blockchain due to increasing block sizes, leading to longer confirmation times and higher fees as the network grows. DAG is designed to be more scalable. Both technologies are secure against attacks like double-spending and tampering, but the security properties differ.
Examples of DLT in Logistics: The U.S. Air Force has taken steps to explore blockchain for supply chain management, with several commercial logistics companies and Chinese-owned shipping companies already utilizing this technology. Global logistics giants, DHL and UPS, leverage blockchain to enhance supply chain transparency, reduce fraud, and improve tracking of high-value items during shipping. On the other hand, China’s Global Shipping Business Network (GSBN) leads in blockchain adoption in maritime shipping.
DAG Technology: While blockchain is widely adopted, DAG is an innovative technology that demands further development, testing, and evaluation. IOTA, utilizing the Tangle, is a notable DAG-based distributed ledger focused on scalability, non-linear applications, and resiliency. As technology matures, more logistics companies may explore DAG’s potential for supply chain management.
Securing Supply Chains: To address vulnerabilities and secure supply chains against cyber threats, regular security audits are essential. Independent third-party auditors should conduct these reviews to ensure impartiality. Training and education on encryption’s importance and proper implementation should be mandatory for all supply chain personnel, with regular refresher courses to keep personnel up to date.
Recommendations/Conclusion :
The Department of Defense faces significant challenges in securing its digital logistics in contested environments. These challenges require a multifaceted approach, integrating innovative technologies, comprehensive training, and rigorous supply chain risk management.
By adopting distributed ledger technology, including blockchain and DAG, the DOD can enhance the security and transparency of logistical data, automate processes, and reduce the risk of human error, ultimately ensuring the integrity of supply chains.
