The rapid development of IoT leads new kinds of services which does not existed. And, it requires several changes on existing network. Software Defined Network is one of the future network technology which can deal with problems from these kinds of changes. The strong point of Software Defined Network is flexibility and scalability. However, In some cases, these factors could be the security vulnerabilities. In this paper, we present adaptation of F(I)MEA technique for the security analysis on Software Defined Network Technology for IoT services.

The IoT(Internet of Things) is based on the development of sensor technology and high-speed communication infrastructure, and the number of IoT connected to the network is increasing more than the number of people, and the increase is also very fast. In the field of defense, IoT is being deployed in various fields such as operations, military, base defense, and informatization, and the need is also increasing. Unlike the existing PC/server information protection system, cyber threats are also increasing as IoT sensors, which are vulnerable to information protection, are increasing in the network, so it is necessary to study the platform to protect the defense information and communication network. we investigated the case of connecting wired and wireless IoT to the defense network, and presented an efficient interlocking design method of the IoT integrated independent network with enhanced security by minimizing the contact point with the defense network.

The Internet of Things (IoT) connects all markets and industries, enabling new business models for a variety of services and service providers. The Internet of Medical Things (IoMT) not only accelerates medical advances, but also enables treatment with a more human approach. In addition, it improves treatment methods and quality of precision medical care through data, enables timely treatment, and improves operational productivity of medical institutions through a simplified workflow. However, since the medical field directly affects human health and life, securing security has become an issue above all else, and is a target for hackers trying to exploit it. Therefore, in this study, IoMT technology and security threats and countermeasures in the medical field are analyzed.

IoT which is the core IT of the 4^th industrial revolution, is providing various services from users in the conversion with other industries. The IoT convergence technology is leading the communication paradigm of communication environment in accordance with the increase of convenience for users. However, it is urgently needed to establish the security measures for the rapidly-developing IoT convergence technology. As IoT is closely related to digital ethics and personal information protection, other industries should establish the measures for coping with threatening elements in accordance with the introduction of IoT. In case when security incidents occur, there could be diverse problems such as information leakage, damage to image, monetary loss, and casualty. Thus, this paper suggests a certificate management technique for safe control over access in IoT-based Cloud convergence environment. This thesis designed the device/user registration, message communication protocol, and device renewal/management technique. On top of performing the analysis on safety in accordance with attack technique and vulnerability, in the results of conducting the evaluation of efficiency compared to the existing PKI-based certificate management technique, it showed about 32% decreased value.

Blockchain, which emerged with the development of IT technology, has emerged as a new technology in security in recent years, although it has only been known as a technology associated with digital currencies, such as bitcoin. In particular, various studies have been conducted involving biometric technology and blockchain in the security of the mobile environment, and blockchain-based certifications between different devices are also presented in the IoT base of the wireless mobile environment. In this paper, we want to analyze the trends that are currently being applied to various wireless mobile environments and set up guidelines for future blockchain research.

작년까지 국내에서 대형 침해사고는 2년마다 발생하였으나, 올해 초 대규모 개인정보 유출 사고가 발생하면서 그 암묵적인 2년 룰은 깨졌다. 연이은 침해사고 발생으로 보안의 중요성은 크게 증대되고 있으며, 사이버 공격기술은 대응기술의 발전을 앞질러 빠르게 고도화되고 있고, 그에 대한 피해 또한 가파른 증가세를 보이고 있다. 이에 전 세계적으로 보안시장은 꾸준한 성장세를 보이고 있으며, IoT를 필두로 초연결 시대로 접어드는 시점에서 그 중요성은 날로 증대되고 있다. 전 세계적으로 특히 국내는 연이은 대형 보안사고를 경험해서인지 모르겠으나, 보안은 비용이라는 인식에서 벗어나, 경제적 사회적 비용 측면에서 꼭 필요한 요소라는 인식이 저변에 확대되고 있으며, 다른 분야에 비해 보안 투자는 꾸준히 증대되는 양상을 보이고 있다. 더 나아가 이제는 보안을 차세대 먹거리 산업으로써 육성하려는 정책이 마련되어 추진되고 있으며, 국가 차세대 ICT 신산업 육성 계획을 검토하는 과정에서도 보안이 꼭 고려되어야 하는 요소로 자리매김하고 있다. 이에 본 특집에서는 최근의 사이버 공격 양상과 국내 기술 및 시장 상황을 간략하게 살펴보고, 빅데이터 보안, APT 공격 대응기술, IoT 보안 등 우리가 글로벌 경쟁력을 가질 수 있는 보안 분야와 표준화 이슈에 대하여 살펴보고자 한다.

Recently 5G technology is one of the technologies that has been receiving much positive responses from users as it is integrated with virtual technology. However, 5G's security issues have not been fully resolved and more security is soon required. In this paper, an approach technique is proposed as a probability-based hierarchy to provide personal privacy for 5G-based IoT users more safely. The proposed technique is aimed at not exposing the privacy of IoT users to third parties by using two random keys created personally by IoT users. In order to satisfy both safety and efficiency, the proposed technology divides the privacy of IoT users into two layers. In the first stage, IoT users will control access to intermediate media using anonymous keys generated by IoT users, and in the second stage, information of IoT users registered with servers will be darkened and replicated. The proposed technique has improved the accuracy of the privacy protection of IoT users as they assign weights to layered information after layering users' privacy information on a probabilistic basis.
