In March 2017, the State of New York became the first state to implement regulation specific to cybersecurity for financial institutions. Unlike previous regulations regarding information security, it has set a minimum requirements to establish cybersecurity program based on risk assessment results, protect Nonpublic Information, designate of CISO, and report to regulatory entity. This paper presents a need for a new cybersecurity policy in Korea by examining newly adopted cybersecurity regulation in the United States. Finally, the paper identify policy suggestions based on the United States's approach as they have successfully implemented the program.

국내 개발보안 제도는 2012년 12월부터 '소프트웨어 개발보안 제도'를 의무화 하며 시작 되었다. 3년여가 지난 지금 시점에서 소프트웨어 개발보안 제도는 안정화가 되어가고 있지만 보완할 사항도 일부 있다. 이러한 상황에서 본 연구는 제도가 먼저 정착된 미국의 개발보안 제도의 동향과 국내에서 개발보안 제도가 정착되는 과정에서의 변화된 점에 대해서 분석한다. 또한 개발보안 제도를 더욱 활성화하기 위한 개선 방향에 대해서 제시한다.

국제 인터넷주소 할당기관인 IANA(Internet Assigned Numbers Authority)는 2011년 2월 4일 글로벌 IPv4 주소 할당 중지를 선언하였다. 이로 인해 IPv4를 대신할 차세대 인터넷 주소체계인 IPv6로의 전환이 시급한 상황이다. 하지만 IPv4/IPv6 전환 과정에서 IPv4 네트워크와 IPv6 네트워크의 공존으로 인해 인가 되지 않은 터널링과 같은 보안 위협이 발생할 수 있다. 본 논문에서는 IPv6로의 전환을 위해 최근 새롭게 연구되고 있는 전환기술의 보안취약성 및 강화방안에 대해 논의하였다.

최근 개인정보 유출 등으로 인해 정보시스템의 보안약점 및 소스코드 품질에 대한 관심이 높으며, 특히 개인자산과도 관련된 금융 정보 시스템의 경우에는 더욱 높다. 해당 시스템의 보안성 강화를 위해서는 개발단계에서부터 보안취약점과 코드의 품질을 높일 수 있는 정적분석 기반의 진단도구 활용이 중요하다. 많은 분야에서 진단도구의 활용이 이루어지고 있지만 금융 정보시스템의 경우 다른 SW 와 특성이 다르기 때문에 추가적인 진단규칙이 반영된 진단도구의 활용이 필요하다. 본 논문은 여러 진단도구 중 전자정부개발에 사용하고, 비교적 진단규칙 추가가 용이한 PMD 에 추가 진단규칙을 반영한 후 생명보험 정보시스템에 적용하고 이에 대한 PMD 검출 계수를 분석한다.

정보통신기술이 발전함에 따라 미래 해양산업에는 첨단 ICT 기술을 중심으로 두고 패러다임이 변화하고 있다. 해양 선박 분야에서는 현 단계인 스마트 쉽(Smart Ship), 자율운항선박(MASS) 등 육상과 선박간의 통신기술이 필요한 시점에서 사이버 공격 위험으로부터 자유로울 수 없다. 선박 간의 사용자 인증은 선박의 보안을 강화하고 인가된 사용자 만이 선박 시스템에 접근하고 조작할 수 있도록 하는 중요한 요소이다. 보안 요구 사항과 해당 규정에 따라 설계되고 구현되어야 하며, 또한 중요한 측면은 인증 시스템의 안전성과 안정성을 유지하기 위해 주기적인 업데이트와 강화된 보안 대책을 시행하는 것이다. 본 논문에서는 선박 간의 사용자 인증기술에 대해서 알아보고 다양한 방법에 대하여 제안하였다.

As information is recognized as a core competency of organizations, organizations are increasingly investing in policies and technologies for information security(IS). Recently, as information exposure accidents by people have occurred continuously, interest in IS behaviors of organization insiders is increasing. This study aims to confirm the effect of the IS environment and support structure established by the organization on the intention of individuals to comply with IS. We conducted a survey of employees in organizations with IS policies and tested the hypothesis using the structural equation of AMOS 22.0 and Process 3.1 using 421 samples. As a result of the analysis, authentic leadership and justice climate, which are factors that build an IS environment, and communication and feedback, which are factors supporting IS compliance, have a positive effect on employees' compliance intention. In addition, authentic leadership, punishment, communication, and feedback were found to reinforce the positive impact of IS justice climate. As the study suggested the overall structural design direction to be pursued to reinforce insider's IS behavior, and the results help to achieve the IS goal.

We studied smart door lock of triple security system that strengthened the security capability as it is thought that the criminal case by security vulnerability of door lock is serious in modern society. Remote locking/unlocking function, voice recognition function through mobile phone application built on Eclipse App and optical fingerprint recognition function are implemented in the door lock. Finally, it was confirmed that the security of the door lock can be strengthened through evaluation results of the app-based operation test, the voice recognition operation test, and the fingerprint recognition operation test on the experiment-made door lock system.

The purpose of this study was to assess the current status of cyber security at the Busan Port container terminal and derive strengthening factors through exploratory research. In recent years, the maritime industry has actively adopted Fourth Industrial Revolution technologies, resulting in changes in the form of ports, such as automated and smart terminals. While these changes have brought positive improvements in port efficiency, they have also increased the potential for cyber security incidents and threats, including information leakage through cargo handling equipment and ransomware attacks leading to terminal operations disruption. Especially in the case of ports, cyber security threats can have not only local effects within the port but also physical damage and implications for national security. However, despite the growing cyber security threats within ports, research related to domestic port cyber security remains limited. Therefore, this study aimed to identify factors for enhancing cyber security in ports and derive future enhancement strategies. The study conducted an analysis focusing on the Busan Port container terminal, which is one of the leading ports in South Korea actively adopting Fourth Industrial Revolution technologies, and conducted a survey of stakeholders in the Busan Port container terminal. Subsequently, exploratory factor analysis was used to derive strengthening factors. This study holds significance in providing directions for enhancing cyber security in domestic container ports in the future.

Global cyber threats to industrial control systems are increasing. As a result, related research and cooperation are actively underway. However, we are focusing on strengthening security for physical network separation and perimeter. Internal threats are still vulnerable. This is because the easiest and strongest countermeasure is to enhance border security, and solutions for enhancing internal security are not easy to apply due to system availability problems. In particular, there are many vulnerabilities due to the large number of legacy systems remaining throughout industrial control systems. Unless these vulnerable systems are newly built according to the security framework, it is necessary to respond to these vulnerable systems, and therefore, a security solution considering availability has been verified and suggested. Using Sysmon and ELK, security solutions can detect Cyber-threat that are difficult to detect in unstructured ICS.
