Security threats in supply-chains can be targeted at all the users who use products related to these supply-chains as well as at single equipment or individuals. This implies that these security threats can cause nationwide economic and social damages. In particular, it is true that hardware security threat analysis technology in supply-chains has significant technical barriers due to the lack of software knowledge as well as the need to study and understand undisclosed hardware designs. In this paper, we discuss the future direction of studies by introducing basic concepts and attack cases, along with domestic and foreign technology trends related to supply-chain security technology.

Effects of food scandals on religious belief, human health and even on causes of death indicate that firms and consumers are vulnerable to integrity risks in the global supply chain. Mitigating the integrity risk and maintaining the credence quality products like halal food is very challenging, if not impossible. Our aim in this research is to show that supply chain integration can mitigate the halal food integrity risk. To illustrate this idea, we have conducted case studies and interviews in seven Malaysian chicken supply chain focal firms. We unpack the halal integrity risks along the supply chain, such as production risk, raw material risk, food security risk, outsourcing practices risk, service risk, and logistics risk. The research argues that supply chain integration, such as internal integration and external integration practices, could minimize the halal integrity risk. The advantages of supply chain integration in mitigating the halal integrity risk are also highlighted in this paper.

The circular economy approach in the coffee supply chain promotes a more sustainable, environmentally friendly, and socially responsible coffee industry. It aims to reduce the environmental impact of coffee production and consumption while ensuring the long-term viability of coffee farming communities and ecosystems. However, there are many challenges in the traditional circular economy coffee supply chain. Hence, this paper undertakes a comparative analysis between the traditional circular economy coffee supply chain and its integration with blockchain. As a result, we display the benefits of incorporating blockchain technology into the conventional circular economy framework of the coffee supply chain. Additionally, this integration promises to overcome the challenges in the traditional circular economy coffee supply chain.

Cross-border supply chains undergone complexity in the global trade process, unpredictability and continually evolving regulations and information requirements. Under these circumstances, longer lead time inhibiting quick response to market demands, unanticipated supply chain costs eroding product cost savings, compliance and documentation errors causing delays and fines are challenging global trade companies when they execute global business. These problems are mainly caused by unautomated, unintegrated process which lead to longer and more unpredictable lead times, slower cash flow, cost overruns, and ultimately lower profits and less satisfied customers. Complex and unpredictable global trade environment requires global trade companies of global trade management functions to automate and control this complex environment for driving out cost, time and risk from their business. Global trade management allows cost savings, supply chain efficiencies and improved compliance through improving global supply chain visibility, facilitating cash flow by supply chain financing, enhancing supply chain security and risk management.

Radio Frequency Identification (RFID) skill is becoming a technology that might deliver a response to manual glitches. The use of tags, receiver and wireless surfs to join with each other would mean that RFID in combination with the EPC would speech these pain opinions and offer many welfares in different sectors such as production, distribution, trade, logistics, and security. Potential benefits include increased visibility rising supply chain, enlarged proficiency and cost savings through improved data harmonization, better responsiveness to actual prominence change. Trendy the case of the textile or industrial applications, recent systems used by the industry to control the supply chain in addition strength discernibility are being studied, besides improvements in the overall perceptibility of assets are anticipated through labels, readers, drivers, POEs, etc. this model will be developed with new situations and a lively construction industry. It will be focused on Cost, Hardware compatibility, security and maintenance issues.

Data confidentiality refers to the characteristic that information kept undisclosed or hidden from unauthorized parties. It considered a key security requirement in current supply chain management (SCM) systems. Currently, academia and industry tend to adopt blockchain and IoT technologies in order to develop efficient and secure SCM systems. However, providing confidential data sharing among these technologies is quite challenging due to the limitations associated with blockchain and IoT devices. This review paper illustrates the importance of preserving data confidentiality in SCM systems by highlighting the state of the art on confidentiality-preserving methodologies in the context of blockchain based IoT-SCM systems and the challenges associated with it.

Block Chain is a technology that records and shares distributed ledgers without a central authority, providing a decentralized platform for transparent transactions in the business and enhancing transparency and traceability in all transactions to ensure trust in the transaction. Despite initial doubts about this technology, it is committed to adopting, adapting and improving the technology in a wide range of industries, including finance, government, security, logistics, food, medical, legal, and real estate. This study examines this technology, its applicability and potential benefits to the manufacturing supply chain. A tracking system of manufacturing supply chain to visualize transparency and traceability is implemented, and the conditions for adopting the technology in the manufacturing supply chain and the issues to be addressed are discussed.

미국에서 발생한 9.11 테러 이후 물류보안(Supply Chain Security)에 대한 패러다임이 발생하였으며, 국외의 관련 기업과 기관들은 물류보안을 위하여 다양한 연구들을 진행하였다. 하지만 국내의 경우 물류보안이라는 용어 자체가 생소할 뿐만 아니라 보안에 관한 패러다임이 물류부분까지 확산되지가 않아서 관련 연구가 부족한 실정이었으나, 최근에 물류보안 기술 중의 하나로서 RFID 기반 컨테이너 화물 안전수송 장비인 ConTracer(Container Tracer)를 개발하는 등 관련 연구가 활성화되기 시작하였다. 현재 개발되고 있는 컨테이너 화물 안전수송 장비들의 주요 이슈는 높은 인식률과 충분한 인식거리가 확보되는 것이며, 본 연구에서는 이러한 목적을 달성하기 위하여 다구찌 방법론을 활용하여 ConTracer(433MHz 타입, 2.4GHz 타입)의 인식률 향상을 위한 다양한 실험을 하였다. 실험결과 433MHz 주파수에서는 리더기의 방향을 전방우측으로 향하는 것이 다소 유리하고, 2.4GHz 주파수에서는 크게 영향을 미치지는 못하는 것으로 나타났으며, 안테나의 위치는 예상했던 대로 두 주파수 모두 외부에 설치하는 것이 인식률 향상에 유리한 것으로 분석되었다.

IT 기술의 급속한 발전과 함께 기존 산업과의 융합을 통해 4차 산업혁명 기술을 기반으로 프로세스의 간소화 및 생산성을 높일 수 있는 스마트 제조가 증가하고 있으며, 이와 비례하여 공급망 공격에 대한 보안위협도 증가하고 있다. 공급망 공격의 경우 사전 탐지가 힘들고 피해 규모가 매우 크다는 점 때문에 차세대 보안 위협으로 부상하고 있으며 이에 따른 탐지 기법에 대한 연구가 필요하다. 따라서 본 논문에서는 오픈소스 기반 분석 솔루션인 ELK Stack과 Sysmon을 통해 다중 환경에서 실시간으로 로그를 수집, 저장, 분석 및 시각화하여 공급망 공격에 대한 이상 행위 등의 정보를 도출하여 효율적인 탐지 기법을 제공하고자 한다.

Before an IT product is used, there is a sequence of the process such as the components supply-demand of the product, their assembly and production, their logistics and delivery, and then finally, the product can be used by a user. During this sequence of the process, there can be many security exposures and risks. In this paper, we show, by examining security cases of various IT products, that there are many security exposures in the process of IT products from their production to their delivery to end users and in their use, and also show how critical the security exposures are. Even though there are various security theories, technologies and security controls, there is still weak link from the production of an IT product to its use, and this weak link can lead to security vulnerabilities and risks. This paper tries to call attention to the importance of the execution of the security control and the control components. We examine the practical cases to find out how the security control is paralyzed, and to show how it is compromised by asymmetric security resources. Lastly, from the cases, we examine and review the possible domestic security issues and their countermeasures.
