안드로이드 보안카드 앱은 보안카드를 암호화하여 스마트폰에 저장하고 관리하는 앱으로 사용자의 편의성을 향상 시켜주지만 안드로이드의 특성상 앱 설치 파일로부터 키 노출의 위험이 있다. 본 논문은 안드로이드 보안카드 앱의 디컴파일로부터 키를 추출하는 취약점을 설명하고 보안카드를 대체하기 위해 OTP 사용을 제안한다.

제조 분야의 미래유망기술로써 각광받고 있는 3D프린터 기술은 다양한 방식으로 활용되고 있다. 시제품의 제작비용과 시간을 절감시키고 1인 맞춤형 제품 생산이 가능하게 하였으며, 의료 및 산업분야 전반에 걸쳐 그 시장과 규모는 나날이 증대되고 있다. 하지만 이에 반하여 환경오염, 무기제작, 지적재산권, 의료 윤리 및 규제, 국가 보안 위험 등과 같은 문제점 또한 적지 않게 제기되고 있다. 본 고에서는 정보보호 관점에서 네트워크와 연결된 3D프린터가 가진 잠재적인 취약점에 대해 알아보고, 조직에서 이를 예방하기 위한 관리적 방법에 대해 NIST IR 8023의 생명주기에 기반 한 단계별 위험관리 및 위험평가에 대한 가이드를 제공하고자 한다.

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.

Recently, the demand against the system risk analysis and security management from the enterprises or the agencies which operate a information system is increasing even from domestic. The international against the standardization trend of information protection management system it investigates from the dissertation which it sees. It analyzed and against information property information protection management system integrated it will be able to manage a danger modeling it did it proposed. Having analyzed as well as compared the matureness of security-measurement models in regard to the global standard of proposal system, the administrative presentation for various IT technology resources. which have been managed singly so far, is now well applied under the united control of the company itself, and enabled the automated management of authentication support and renewal for ISO 27001, ISO 9000, ISO 14000, resulting in much advanced operation for both material and human resources.

보건의료정보는 개인의 가장 민감한 정보로 최상의 보호가 이뤄져야하는 한편, 국민 건강과 복지 향상을 위한 공익의 성격도 강하여 관리와 책임에 대한 명확한 지침이 반드시 필요하다. 본 연구에서는 보건의료 부문의 특성과 정보화 현황을 반영하고 선행연구의 한계점을 보완하여 국내 보건의료 환경에 적합한 정보보호관리 모델을 개발하였다. BS7799, HIPAA Security Rule, HL7 EHR SIG 기능명세 등을 참고하여 필요성, 정보보호 목적/전략 수립, 위험분석/평가, 정보보호관리 정책수립, 정보보호관리 프레임워크 설계, 관리적 보안, 물리적 보안, 기술적 보안, 정보보호관리 평가,운영관리의 총 10개 세부 프로세스와 111개의 이행지표로 구성된 본 모델은 보건의료정보 취급자에게 실행 지침을 제공하여 보건의료정보시스템의 안정성 향상과 국민 보건복지 수준 향상에 이바지할 수 있을 것으로 기대된다.

Following the development of Internet of Things (IoT) technology, the scope of application of IoT technology is expanding to industrial safety areas that detect and prevent possible risks in outdoor environments in advance, away from improving the convenience of living in indoor environments. Although this expansion of IoT service provides many advantages, it also causes security problems such as data leakage and modulation, so research on security response strategies is being actively carried out. In this paper, the IoT-based road construction risk management system in outdoor environment is proposed as a research subject. As a result of investigating the security vulnerabilities of the low-power wide-area (LPWA, BLE) communication protocol applied to the research targets, the security vulnerabilities were identified in terms of confidentiality, integrity, and availability, which are the three major elements of information security, and countermeasures for each vulnerability were proposed. This study is meaningful in investigating and analyzing possible vulnerabilities in the operation of the IoT-based risk management system and proposing practical security guidelines for each vulnerability.

An era of smart manufacturing is coming through the rapid development of information and communication technology. As a result, many companies have begun to utilize a variety of hardware and software for the efficient business of the manufacturing process. At this time, the hardware and software used are supplied through manufacturing and distribution processes. These supply processes are exposed to a variety of security threats. As the recent cases of supply chain attacks have increased, foreign countries are establishing supply chain management systems and managing supply chain risks. In Korea, on the other hand, there was research on supply chain risk management in some fields. In this paper, we emphasizes the necessity of supply chain risk management through supply chain attack cases. In addition, we analyze trends of foreign supply chain management system and explains the necessity of domestic supply chain security strategy.

Traditionally banks and other financial institutions use customers' accounts and information managed by them and provide payment services in dominant positions. Recently, EU amends Payment Services Directive to institutionally guarantee access to customers' accounts and use of account-related information even to third parties, which facilitates competition in financial markets and promotes innovation. However, this kind of change can increase potential security risks and therefore institutional responses from financial authorities are required so that all participants in financial markets can properly respond to security risks. In this study institutional responses to the security risks in the EU's new Payment Services Directive (PSD2) are analyzed, comparisons between this and domestic electronic financial regulations are analyzed, and implications for the direction of improving domestic electronic financial regulations will be suggested.

Today, network is a fragile state in many threat attacks. Especially, the company serviced like internet or e-commerce is exposed to danger and targeted of attacker Therefore, it is realistic that the company use the security solution. It exist various security solution in our school network. For example, Firewall, IDS, VirusWall, VPN, etc. The administrator must manage various security solution. But it is inefficient. Therefore, we need the Management System to controll every security solution. In this paper, we deal with basic contents of security solution to manage the ESM and merits and demerits when use it. Also we suggest method that the Administrator can manage his network more efficiently and systematically by using the ESM in our school network.
