This study is a demand research for the selection of public safety science and technology equipment and suggests an empirical research method. The technology demand survey is the beginning of the selection of innovative technology. And it is the basis of collecting information required for the technology required in the market and helping to apply it to the field. The demand survey for police science and technology can reduce the uncertainty of crime prevention and help the smooth implementation of security policies. However, in Korea, adoption of security science and technology equipment was centered on social issues or researchers' opinions rather than the demands of field users. Until, there was no research has been conducted on the demands of field police officers for selection of security science and technology equipment in Korea. Also, there was no preferential study for the demand for security science and technology equipment. Therefore, this study proposes a methodology that can systematically identify the needs for the technology and equipment of field experts suitable for the public security situation for the selection of security science and technology equipment. Specifically, we propose a sample design for a technology classification system and a survey tool for technology awareness and satisfaction. It is expected that this tool will provide a classification system for security science and technology equipment selected for the Korean police and will help determine the priority of equipment suitable for the field.

Nepal is a sensitive and disaster-prone country where safety and security risk are of high concern for travelers. Digital technologies can play a vital role in addressing safety and security issues in the country. This research work proposes a Digital tourism security system design for addressing the safety and security issues in tourism industry of Nepal. The study uses Design science research methodology to identify artifacts, interactions, information flow and dependencies between them which are then mapped with existing prevalent technology to provide design solutions. Data is obtained from interview of tourist and experts as a primary source and technical documents/draft, software documentations, surveys as secondary source. Generalized information model, Use cases model, Network architecture model, Layered taxonomy model and Digital tourism technology reference model are the outcomes of the study. The work is very important as it talks specifically about implementation and integration of digital technologies in tourism security governance at federal, provincial, municipal and rural level. The research supplements as a knowledge document for design and implementation of digital tourism security system in practice. As there is very less work on digital systems in tourism security of Nepal, this work is a pioneer and first of its kind.

네트워크 공격 대응에 관한 보안기술의 기존 연구들은 하드웨어적 네트워크 보안 기술을 이용하여 네트워크의 보안성을 높이는 방법이나 바이러스 방역 백신과 바이러스 방역 시스템이 주로 제안 설계되어왔다. 많은 사용자는 라우터의 보안 기능을 충분히 활용하지 못하고 있어 이러한 문제점을 극복하기 위해 네트워크 보안 수준에 따라 분리함으로써 계층화된 보안 관리를 통하여 외부에서의 공격을 차단할 수 있음을 계층별 실험을 통해 분류하였다. 연구의 범위는 Edge 라우터의 보안기술 동향을 살펴봄으로 Edge 라우터 기반의 네트워크 공격에 관한 위협으로부터 보호하는 방법과 구현 사례를 제시한다.

국방부는 국방혁신 4.0 계획에 기반한 첨단과학기술군 육성을 위해 AI를 향후 전력 증강의 핵심 기술로 활용할 계획이다. 그러나 AI의 특성에 따른 보안 위협은 AI 기반의 국방정보시스템에 실질적인 위협이 될 수 있다. 이를 해소하기 위해서는 최초 개발 단계에서부터 체계적인 보안 활동의 수행을 통한 보안 내재화가 필요하다. 이에 본 논문에서는 AI 기반 국방정보시스템 개발 시 단계별로 수행해야 하는 보안 활동 수행 방안을 제안한다. 이를 통해 향후 국방 분야에 AI 기술 적용에 따른 보안 위협을 예방하고 국방정보시스템의 안전성과 신뢰성을 확보하는데 기여할 수 있을 것으로 기대한다.

Growing information threats have threatened organization to lose information security controls in these days. Many organizations have accepted the various information security management systems does mention necessity of a continuous evaluation process for the executions of information security management in a theoretical aspect. This study suggests a continuous evaluation process for information security management reflecting the real execution of managers and employees in organizations.

Recently, to use the evaluated firewall is recognized as a solution to achieve the security and reliability for government and organizarions in Korea. Results of firewall evaluation using ITSEC(Information Technology Security Evaluation Criteria) and CCPP(Common Criteria Protection Peofile)have been announced. Because there are problems to apply ITSECor CCPP for the firewall evaluation in korea environment, korea government and korea Information security Agency (KISA) decided to develop our own security dvaluation critrtia fir firewalls.As a result of the efforts, Korea firewall security evaluation criteria has been published on Feb. 1998. In this paper, we introduce Korea security evaluation criteria for firewalls. The ceiteria consists of functional and assurance requirements that are compatible with CC Evaluation Assurance Levels(EALs)

The purpose of this study is to find the continuance intention to use for reCAPTCHA technology which has information security and social contributions (decrypting archives) according to the user's pro-social level. In this research, reCAPTCHA technique generally gives users to information security and decrypting archives. However, as a result of preliminary survey, most users were not even aware of information security and social contributions (decrypting archives) functions. Therefore, in this research, we will measure with two kinds of focus. The first is the assumption that there will be also a difference in the continuance use depending pro-social level of the user of information technology, second we explain only the function of information security to the first group as well as decrypting archives to the second group. Generally, pro-social means that degree of understanding and supporting to the other people's interest, actions, needs, help, and care. In this research, we assume that if users have a low level of others care, they might evaluate that reCAPTCHA technology's social contributions is low. While they have a high level of others care, they recognize reCAPTCHA technology's social contribution is high and then they tend to use this technology continuously. Through this research, we finally find the most efficient way to increase the degree of continuance use of information technology.

This study examines the relationship between the organizational member's information security mind and organizational information security level. The influential relationships among organizational members' information security mind are investigated, and the relationship between organization's information security level and information security mind has been analyzed. As a result, too manager's information security mind is shown to give the biggest influence to other group in the organization. A strong positive correlation exists between organizational member's information security mind and the level of organization's physical, technical, managerial information security. However, there is no significant difference in information security level by types of business. In the future, a more profound study on information security mind is necessary. And alternative methods of information security level estimation need to be studied.

중소기업은 대기업에 비해, 정보기술에 대한 의존도가 높지만, 재정적인 어려움과 한정된 자원 및 노하우의 부족 등의 이유로 인해서 정보기술 및 정보 보안에 투자하는 비용은 크지 않다. 이로 인해서 정보 보안에 취약점이 많으며, 그로 인한 침해 사고도 많아지게 된다. 중소기업의 정보 보안 실무자들은 바이러스 방역 솔루션을 업데이트하고, 방화벽을 운영하며, 정기적인 시스템 패치를 적용하는 것이 정보 보안의 전부라고 생각한다. 하지만 보안 사로를 줄이기 위해서 보안 정책, 정보 유출 방지, 사업 연속성, 접근 제어 및 기타 많은 정보 보안 이슈들이 고려되어야지만 한다. 본 논문에서는 이러한 관점에서 대기업 위주의 보안 대책과 전략들을 중소기업 정보시스템의 안정적 운영에 적합하도록 새롭게 정리하여, 4가지의 관점엥서 정보 보안 고려 사항들을 도출하고, 정보 보안 전략을 제안한다.
