Supply chain attacks target critical infrastructure, causing large amounts of damage and evolving into a threat to public safety and national security. Accordingly, when establishing cybersecurity strategies and policies, supply chain risk management is specified to enhance security, and the US Biden administration recently issued the Executive Order on Improving the Nation's Cybersecurity, SBOM was mentioned as part of the guidelines for strengthening software supply chain security. If the government mandates SBOM and uses it as a security verification tool for supply chains, it can be affected by the domestic procurement system in the future and can be referenced when establishing a security system for domestic supply chains according to the progress of policy implementation. Accordingly, in this paper, countries that are promoting the SBOM policy as a way to strengthen the security of the software supply chain were selected and analyzed with a focus on related cases. In addition, through comparison and analysis of foreign SBOM policy trends, methods for using domestic SBOM in terms of technology, policy, and law were considered. As the value of using SBOM as a supply chain integrity/transparency verification tool is expected in the future, it is necessary to continuously identify trends in the establishment of international standardization and policy development for SBOM and study the standard format.

With the development of ICT, the use of software has become essential for organizations to exchange information or manage operations. However, security and software management issues that have increased with the development of ICT are issues that need to be continuously addressed. In 2021, the U.S. government has standardized and established SBOM as one of the countermeasures for software security. This research was initiated as a study to lay the groundwork for the introduction of SBOM in Korea. Based on the effects of SBOM characteristics on adoption intention, we tested management support and institutional support as moderating variables. As a result, security management was found to be a significant moderating variable for management support, and transparency was found to be a significant moderating variable for government institutional support. This study verified that SBOM adoption requires both corporate and government efforts, and the variables that are important from each perspective are different. We hope that this study will contribute to the development and adoption of SBOM.

Advances in technology have made it easier for organizations to share information and collaborate. However, collaboration systems where multiple entities share and access information are vulnerable to security. The concept of Software Bill Of Materials (SBOM) has emerged as a way to strengthen information security by identifying and transparently managing the components of software programs. To promote the adoption of SBOM in Korea, this study investigated the intention to use of collaboration system managers. This study was based on the theory of planned behavior and the integrated technology acceptance theory. The results of this study confirmed that performance expectations from SBOM adoption were an important variable for intention to use, and positive attitudes toward security also had an indirect effect through performance expectations. We found that SBOM adoption has an important causal relationship with performance due to the fact that it is targeted at enterprises, and that positive attitudes toward security and social climate can have a strong effect on intention to use.

2021년에 발생한 일련의 소프트웨어 공급망 공격으로 미국 연방 정부의 사이버보안 개선 정책이 가속됐다. 이중 소프트웨어 구성 정보를 유통하는 SBOM 정책은 SW 구성요소의 투명성을 강화하여, 이를 활용하는 공급자와 수요자의 보안 인식 개선에도 도움을 줄 것이 기대된다. 다만 SBOM으로 공급망 보안 위협을 완화하려면 해결해야 할 기술적 이슈가 있고, SBOM 수집자를 위한 구체적인 가이드도 마련되지 않아 제도 정착에는 시간이 걸린다. SW 공급망 문제는 SW 개발 관행에 대한 지속적인 개선이 요구되며, 글로벌 연쇄 위험으로 결코 혼자서는 해결할 수 없다. 따라서 우리는 실태조사, 실증사업 등을 시작으로 현실에 맞는 정책을 먼저 적용하고, 제도적 조화를 위한 국제협력에도 힘써야 한다.

The increased adoption of open source security management in supply chains is gaining worldwide attention. In particular, as security and threatening situations, such as solar winds, Kaseya ransomware, and Log4j vulnerability, are becoming more common in supply chains using software (SW)-defined networks, SW bills of materials (SBOMs) for SW products should be prepared to protect major countries like the United States. An SBOM provides SW component information and is expected to become required for SW supply chain management. We focus on SW supply chain management policies and SBOM trends in major countries and private organizations worldwide for safe SW use and determine the current status of Korea and ETRI's open source SW supply chain management trends.

2021년 5월 12일, 미(美) 바이든 행정부는 소프트웨어 공급망 보안 강화를 위한 대통령 행정명령 14028을 발표하였다. 이후 연방정부에 납품하는 핵심 소프트웨어에 대해 SBOM(Software bill of materials) 제출이 의무화됨에 따라, 2021년 하반기부터 소프트웨어 공급망 관리를 위한 다양한 솔루션이 빠르게 개발되고 있다. 하지만 활발한 연구 및 산업화가 이루어지고 있는 글로벌 정세와 달리, 국내 산업은 상대적으로 더딘 실정이다. 이에 따라 본 논문에서는 소프트웨어 공급망 및 SBOM 관리를 제공하고 있는 글로벌 기업과 해당 솔루션에 대해 소개한다. 향후 국내 시장도 소프트웨어 공급망 보안 강화를 위해 SBOM 관리 의무화가 예상되는바 관련 솔루션의 개발 연구가 요구된다.

최근 몇 년 동안 엄청난 양의 데이터 혁신이 진행되어왔고, 그에 따라 소프트웨어 개발의 편리성을 위해 오픈소스를 사용하는 경우가 많아졌다. 이로 인해 소프트웨어 생산성 측면에서는 많은 도움이 되었지만, 보안 관점에서는 많은 문제를 야기했다. 이러한 OSS 사용에 따른 위험을 줄이고자 OSS 추적성을 위한 도구를 사용하는 방법이 지속적으로 개발되었지만, 아직까지도 OSS 사용에 따른 위험은 증가하고 있다. 이에 본 논문은 OSS 추적성의 보완을 위한 SBOM(Software Bill of Materials)의 정의와 현재 국외 SBOM 추진 동향에 대해 소개하고자 한다.

Recently, supply chain attacks against nuclear facilities such as "Evil PLC" are increasing due to the application of digital technology in nuclear power plants such as the APR1400 reactor. Nuclear supply chain security requires a asset management system that can systematically manage a large number of providers due to the nature of the industry. However, due to the nature of the control system, there is a problem of inconsistent management of attribute information due to the long lifecycle of software assets. In addition, due to the availability of the operational technology, the introduction of automated configuration management is insufficient, and limitations such as input errors exist. This study proposes a systematic asset management system using SBOM(Software Bill Of Materials) and an improvement for input errors using natural language processing techniques.

Recently, ICT companies do not directly design, develop, produce, operate, maintain, and dispose of products and services, but are outsourced or outsourced companies are increasingly in charge. Attacks arising from this are also increasing due to difficulties in managing vulnerabilities for products and services in the process of consignment and re-consignment. In order to respond to this, standards and systems for security risk management of ICT supply chain are being established and operated overseas, and various case studies are being conducted. In addition, research is being conducted to solve supply chain security problems such as Software Bill of Materials (SBOM). International standardization organizations such as ISO have also established standards and frameworks for security of ICT supply chain. In this paper, we presents ICT supply chain security management items suitable for domestic situation by comparing and analyzing ICT supply chain security standards and systems developed as international standards with major countries such as the United States and EU, and explains the necessity of cyber security framework for establishing ICT supply chain security system.

In order to respond to supply chain threats, active research and development efforts are underway for software tamper prevention technologies such as Secure Boot and management systems like Software Bill of Materials(SBOM). Particularly, the Trusted Computing Group (TCG) is introducing standards for Trusted Platform Module(TPM) to provide a secure and trustworthy computing boot environment. This paper emphasizes the need for introducing secure booting technology for cryptographic modules to ensure that they remain safe and provide reliable functionality even in the face of supply chain threats. Furthermore, it analyzes vulnerabilities in cryptographic modules verified by the ISO/IEC 19790 standard and proposes security requirements for secure booting of cryptographic modules to address these vulnerabilities.
