자율운항선박 (Maritime Autonomous Surface Ship, MASS) 관련 기술은 전 세계적으로 활발히 개발 중이다. 이와 더불어 선박정보 통신 기술(ICT)을 활용한 선박 관리에 대한 수요가 증가하면서 선박 데이터의 신뢰성 확보가 더욱 중요해지고 있다. 선박에서 사용하는 데이터는 점차 복잡해지고 용량이 증가함에 따라 체계적인 관리 방안이 필요하다. 본 연구에서는 주요 선급에서 발간한 기술자료와 표준동향 분석 및 전문가 논의를 통해 신규 표준 아이템을 도출하였다. 이를 기반으로 ISO 선박 및 해양기술 분과에 제안한 선박 데이터 신뢰성 확보를 위한 데이터 품질 관리 표준 제안한 결과를 소개하고자 한다. 신규 제안한 표준을 통해 국내 조선소 및 기업에서 개발한 선박 성능 분석 및 모니터링 시스템에 대한 품질 검증에 활용할 수 있을 것으로 예상된다.

With the emergence of serverless computing paradigm and the innovations of cloud technology, the structure of backend server infrastructure has evolved from on-premises to container-based serverless computing. However, an access control on the server still heavily relies on the traditional SSH protocol, which poses limitations in terms of security and scalability. This hampers user convenience and productivity in managing server infrastructure. A web shell is an interface that allows easy access to servers and execution of commands from any device with a web browser. While hackers often use it to exploit vulnerabilities in servers, we pay attention to the high portability of web shell technology for server management. This study proposes a novel proxy-based server management framework utilizing web shell technology. Our evaluation demonstrates that the proposed framework addresses the drawbacks of SSH without additional overhead, and efficiently operates large-scale infrastructures in diverse computing environments.

Cities in the world are rushing to develop smart cities to create a sustainable and happy city by solving many problems in cities using information and communication technologies such as big data and IoT. However, in Korea's smart cities and smart city certification systems, the focus is on platform-oriented hardware infrastructure, and the information security aspect is first considered to build and authenticate. It is a situation in which a response system for the risk of leakage of big data containing personal information is needed through policy research on the aspect of personal information protection for smart city operation. This paper analyzes the types of personal information in smart cities, problems associated with the construction and operation of smart cities, and the limitations of the current smart city law and personal information protection management system. As a solution, I would like to present a model of a personal information protection management system in the smart city field and propose a plan to strengthen personal information protection through this. Since the management system model of this paper is applied and operated in the national smart city pilot cities, demonstration cities, and CCTV integrated control centers, it is expected that citizens' personal information can be safely managed.

The representative concept of the future war is NCW. The main point of NCW is that it is connected by networ ks and gathers the battlefield status in real time, managing and controlling it. This is most needed in the navy. Operations of the navy are carried out in wide areas, individually or together. During this process, sharing information between each warship should be essential. Furthermore in the case of the American navy, they see the entire world as the operation area so it is a representative example of NCW. The C4I system of the Korean army is separated a ccording to the difference of each army's tactics and weapon system, being developed and managed differently. The refore there is a problem of interoperability lacking in each system. This paper analyzes the developed C4I system of the American navy to analyze the problems of C4I system of the Korean army, and propose the future direction of its development.

The 3390 million people, around 83% of the adult population in Korea use smartphone. Although the safety problem of the certificate has been occurred continuously, most of these users use the certificate. These safety issues as a solution to 'The owner of a mobile phone using SMS authentication technology', 'Biometric authentication', etc are being proposed. but, a secure and reliable authentication scheme has not been proposed for replace the certificate yet. and there are many attacks to steal the certificate and private key. For these reasons, security experts recommend to store the certificate and private key on usb flash drive, security tokens, smartphone. but smartphones are easily infected malware, an attacker can steal certificate and private key by malicious code. If an attacker snatchs the certificate, the private key file, and the password for the private key password, he can always act as valid user. In this paper, we proposed a safe way to keep the private key on smartphone using smartphone's unique information and user password. If an attacker knows the user password, the certificate and the private key, he can not know the smart phone's unique information, so it is impossible to use the encrypted private key. Therefore smartphone user use IT service safely.

An APT attack is a new hacking technique that continuously attacks specific targets and is called an APT attack in which a hacker exploits various security threats to continually attack a company or organization's network. Protect employees in a specific organization and access their internal servers or databases until they acquire significant assets of the company or organization, such as personal information leaks or critical data breaches. Also, APT attacks are not attacked at once, and it is difficult to detect hacking over the years. This white paper examines ongoing APT attacks and identifies, educates, and proposes measures to build a security management system, from the executives of each organization to the general staff. It also provides security updates and up-to-date antivirus software to prevent malicious code from infiltrating your company or organization, which can exploit vulnerabilities in your organization that could infect malicious code. And provides an environment to respond to APT attacks.

In Korea, national information infrastructure has been grown well because of the rapid growth and supply of Internet, but threats of cyber terror and cyber war are also increasing. Cyber attacks on knowledge information society threaten industry, economy and security. Major countries realize that cyber attacks can cause national heavy loss. So, they are trying to adopt policy on their cyber safe. And natural environmental crisises are increasing around the world. Countries such as India and Philippine in which tsunami, typhoon and earthquake are often occurring have national systematic disaster management system that can prevent and recover. We need systematic management for prevention and recovery from cyber terror, and need to establish national cyber disaster management system. Therefore, in this paper, we analyze major countries's cyber security policy and suggest a method of establishing the national cyber disaster management system.

Internet baking, e-commerce, business processing, etc on smartphone handing could be possible in present days. Ambiguity between cyber and real life has made vulnerability on infrastructure, Gov't Service and National security by cyber terrorism. Especially, Lots of Infrastructure and Gov't Service based on Information Technology were exposed by Cyber terror. Legal system should be improved to keep from these threats. This paper proposed needs of cyber legal system by analyzing proposed cyber related code on Korean National Assembly, issue on Cyber Control Tower, National Cyber Security Industry and Human resource.

In order to protect the business information of the enterprise, the company is engaged in various information security activities, such as establishing an information security management system, establishing and operating an information security system, checking vulnerabilities and security controls. It is an enterprise information security governance that organizes various information security activities for enterprise business, and it needs to be systematized to operate them effectively. In this study, to systematize the enterprise information security governance, we would like to explore the existing Enterprise Information Portal(EIP) model and propose an Enterprise Information Security Portal(EISP) model based on it. The Enterprise Information Security Portal(EISP) model provides an integrated environment for supporting the activities of the information security departments by systemizing the enterprise information security governance, which is a variety of information security activities of the enterprises, so that the information security activities of the enterprises can participate directly from CEO to executives and employees, not just from the information security departments.
