Security Service is the study for social safety and maintenance of order. Compared with the industrial circle, it has only been 18 years, though, many-sided scholars have been interested in this field and tried. The present Security Service, however, has several problems, so it is difficult to gain recognition as the value of learning. To achieve this, several kinds of prior tasks should get solved. First, Preparation for agreement between Industry and University about the academic concept and establishment of range. Second, Set up the School Register System for the academic establishment of identity. Third, Preparation of the plan for the organization of education system. Fourth, Study Direction different from the industrial world. (Unconcern) Therefore, the alternatives centered on some prior tasks will be suggested to enhance the identity and value of Security Service as the study.

In this paper, we address security issues in 5G non-public networks for industrial applications. In contrast to public networks that offer mobile network services to the general public, 5G non-public networks provide 5G network services to a clearly defined user organization or groups of organizations, and they are deployed on the organization's defined premises, such as a campus or a factory. The main goal of this paper is to derive security threats and potential security requirements in the case that 5G non-public networks are built for discrete and process industries according to the four deployment models of 5G-ACIA (5G Alliance for Connected Industries and Automation). In order to clarify the scope of this paper, we express the security toolbox to be applied to 5G non-public networks in the form of the defense in depth concept. Security issues related to general 5G mobile communication services are not within the scope of this paper. We then derive the security issues to consider when applying the 5G-ACIA deployment models to the industrial domain. The security issues are divided into three categories, and they are described in the order of overview, security threats, and potential security requirements.

가상사설망이 중요한 정보를 원격에 전송한다는 개념만으로 여겨질 때에는 암호화강도에 주목했었다. 그러나 가상사설망 시장이 활성화되면서 보다 많은 트래픽을 효율적으로 처리하기 위하여, 가상사설망 고성능화에 대한 요구가 증대되고 있다. 본 논문에서는 가상사설망에서 성능 측정 시 필요한 항목들을 제시하고 설치한 네트워크 성능에 얼마만큼의 영향을 미치는지에 대해 살펴본다. 이를 위해 네트웍 환경을 IPsec 프로토콜을 사용하는FreeS／WAN 패키지를 활용하여 구성해보고, 자신의 독자적인 프로토콜인 CIPE 프로토콜을 사용하는 cIPe 패키지를 사용하여 다양한 성능지표들을 반영한 성능 측정을 실시하였다. Psec 표준을 준수하여 구현된 FreeS／WAN은 적용하는 방법에 따라 네트워크 성능 차가 상대적으로 크고 cIPe 방법은 암호화 적용 전에 비해서 그다지 큰 차이를 보이지는 않는다. 본 결과들을 고려할 경우, 가상사설망의 성능과 보안을 적절히 유지하는 범위에서 정책과 시스템 사양을 고려하여 가상사설망을 도입하여야 할 것이다.

With increasingly sophisticated cyber threats, accelerating cloud adoption, and the adoption of remote and hybrid work environments due to the COVID-19 pandemic, the traditional security model, in which many businesses implicitly trust everything within their boundaries, is changing without boundaries, allowing data and users The concept of zero trust is getting more and more attention as the fact that it is not suitable for today's increasingly decentralized environment has been highlighted. Zero Trust is a cyber security model on the premise that 'no one trusts'. In principle, there is no safe area or user in the entire system, and internal users are also verified. is a way As telecommuting becomes commonplace due to the COVID-19 pandemic, and existing cyber security measures are facing limitations, Zero Trust technology is drawing more attention. Accordingly, it is expected that the Korean government will also check the status of acceptability of the domestic public and private sectors and tasks that need improvement when introducing Zero Trust with reference to the NIST standard. In this paper, the basic principles, philosophy, and considerations of Zero Trust and Zero Trust are explained, and practical basic measures to strengthen security by combining Zero Trust technology are presented.

Historically, government has facilitated logistics by building the airports, the seaports, the rail and transit lines, subsidized their operations where necessary, and established the basic laws and regulations pursuant to which the industry serves the public. In the late 1990s and early 2000s, Korean government began to prepare the basic laws of logistics and nowadays it has tried to refine national logistics laws to reflect contemporary industry conditions and evolving ideological attitudes. The policy objectives governing logistics regulation have changed significantly since 2000. This article traces the current status of the Korean logistics laws which regulate one of the nation's most important industries and suggests certain amendment of current laws.

If Industrial state-of-the-art technology that made through IT convergence should be to build safely environment that can protect then IT technology and manufacturing industry become convergence and a growth engine become stable positioning. In each industry, there has been a steady effort for the industrial security. However, they introduced only managerial/technical/physical countermeasures. Therefore, it is difficult to find a reference point as industrial security necessity, protecting coverage and things and so on. It is to lack that academic research in industrial security for protecting industrial technology. In detail, a clear definition lack for industrial security. And target range classification lack for industrial security studies. In this study, we redefined the concept of industry security through previous studies. Academic classification designed industrial security studies through delphi method. we analyzed industry security trends based industrial security studies classification and presented domestic industry research orientations.

According to ISO/IEC 9000, quality to satisfy users' requirements when using the product or service is defined as the characteristics of the synthesized concept. Secure web application coding information systems with the reliability and quality of service is one of the determining factor. Secure coding in order to achieve the quality based on the model is necessary. The reason is that the security is in quality properties in the range of non-functional requirements that necessitates. Secure coding for the design of quality systems based on the quality of the definition of quality attributes, quality requirements, quality attribute scenarios are defined, and must be set. To this end, referring to IEEE 1061 quality model for web application, quality model structure is developed. Secure web application architecture design is composed of coding quality of the model systems, web applications draw interest to stakeholders, decision drivers secure coding architecture, quality attributes, eliciting quality requirements of the security settings, creating web application architecture descriptions and security framework.

With current battlefield environment relying heavily on Network Centric Warfare(NCW), existing weaponary systems are evolving into a new concept that converges IT technology. Majority of the weaponary systems are implemented with numerous embedded softwares which makes such softwares a key factor influencing the performance of such systems. Furthermore, due to the advancements in both IoT technoogies and embedded softwares cyber threats are targeting various embedded systems as their scope of application expands in the real world. Weaponary systems have been developed in various forms from single systems to interlocking networks. hence, system level cyber security is more favorable compared to application level cyber security. In this paper, a secure real-time operating system has been designed, implemented and measured to protect embedded softwares used in weaponary systems from unknown cyber threats at the operating system level.

Trusted Computing is a hardware-based technology that aims to guarantee security for machines beyond their users' control by providing security on computing hardware and software. TPM(Trusted Platform Module), the trusted platform specified by the Trusted Computing Group, acts as the roots for the trusted data storage and the trusted reporting of platform configuration. Data sealing encrypts secret data with a key and the platform's configuration at the time of encryption. In contrast to the traditional data sealing based on binary hash values of the platform configuration, a new approach called property-based data sealing was recently suggested. In this paper, we propose and analyze a new property-based data sealing protocol using the weakest precondition concept by Dijkstra. The proposed protocol resolves the problem of system updates by allowing sealed data to be unsealed at any configuration providing the required property. It assumes practically implementable trusted third parties only and protects platform's privacy when communicating. We demonstrate the proposed protocol's operability with any TPM chip by implementing and running the protocol on a software TPM emulator by Strasser. The proposed scheme can be deployed in PDAs and smart phones over wireless mobile networks as well as desktop PCs.
