An integrated security mechanism is one of the key challenges in the open wireless network architecture because of the diversity of the wireless network in open wireless network and the unique security mechanism used in each one of these networks. In the paper we analysed some elements to guarantee security and privacy preserving in distributed IT applications which provide some kind of support to complex medical domains.

With the development of sensor, wireless mobile communication, embedded system and cloud computing, the technologies of Internet of Things have been widely used in real word. Connecting wireless sensor networks with traditional communication networks or Internet, IoT gateway plays an important role in IoT applications. It facilitates the integration of wireless sensor networks and mobile communication networks or Internet. The IoT gateway is a key component in IoT application systems. But It has lot of security issues. We analyzed the issues of security and privacy.

기존의 바이러스 및 악성 코드 백신의 탐지 기법은 대부분 시그너쳐 기반의 패턴 매칭 기법을 사용하고 있다. 이러한 기법의 단점은 새로운 악성 코드가 발생하면 사용자가 매번 시그너쳐를 업데이트를 해야 탐지가 가능하며, 시그너쳐의 업데이트 없이는 알려지지 않은 바이러스 및 악성 코드를 탐지할 수 없다는 것이다. 따라서 이와 같은 패턴 매칭 기법의 단점을 보완하고자 각각의 악성 코드 종류에 따른 시그너쳐를 이용한 탐지 기법이 아닌 악성 행위별 패턴를 이용하여 탐지를 한다면 기존의 기능을 포함한 알려지지 않은 바이러스 및 악성 코드 등을 탐지할 수 있을 것이다. 본 논문에서는 시스템 모니터링을 통하여 악성 행위별 패턴 분석 및 결과에 대해 기술한다.

Sustainable computing is a rapidly expanding field of research covering the fields of multidisciplinary engineering. With the rapid adoption of Internet of Things (IoT) devices, issues such as security, privacy, efficiency, and green computing infrastructure are increasing day by day. To achieve a sustainable computing ecosystem for future smart cities, it is important to take into account their entire life cycle from design and manufacturing to recycling and disposal as well as their wider impact on humans and the places around them. The energy efficiency aspects of the computing system range from electronic circuits to applications for systems covering small IoT devices up to large data centers. This editorial focuses on the security, privacy, and efficiency of sustainable computing for future smart cities. This issue accepted 17 articles after a rigorous review process.

IDS/IPS and networked computer systems are playing an increasingly important role in our society. They have been the targets of a malicious attacks that actually turn into intrusions. That is why computer security has become an important concern for network administrators. Recently, various Detection/Prevention System schemes have been proposed based on various technologies. However, the techniques, which have been applied in many systems is useful for existing intrusion patterns on standard-only systems. Therefore, probe detection of private clouds using BlockChain has become a major security protection technology to detection potential attacks. In addition, BlockChain and Probe detection need to take into account the relationship between the various factors. We should develop a new probe detection technology that uses BlockChain to fine new pattern detection probes in cloud service security in the end. In this paper, we propose a probe detection using Fuzzy Cognitive Map(FCM) and Self Adaptive Module(SAM) based on service security using BlockChain technology.

This paper presents a new assumptions statement generation method for developing TOE security environment section of PP. We surveyed on guides on the assumption statement in CC scheme, and collected and analyzed hundred of assumption statements which are in 26 certified and published real PPs and CC Toolbox/PKB. The CC Toolbox/PKB is included a class of pre-defined assumption statements. From the result of the survey, we developed a new generic assumption statement list, and proposed a assumption derivation method by using the list.

1980년 후반. MIT에 버너스 리 교수가 인터넷 상에 웹(WWW)을 창시하면서부터 우리의 일상생활은 엄청난 변화를 가져왔다. 시 공간을 초월할 수 있는 인터넷이라는 가상 세계에서는 개인뿐만 아니라 정치 경제 사회등 모든 분야에 걸쳐 인터넷을 통한 쉽고 간편하며 빠른 교류가 이루어짐으로써 이제 더 이상 네트워크를 이용하지 않는 분야는 찾아 볼 수 없을 것이다. 그러나 이러한 현실 속에서 인터넷은 항상 순기능만을 수행하지는 않는다. 특히 악성코드를 이용한 사이버 침해 행위 기술이 인터넷의 발전과 함께 동시에 발전함으로써 이제는 악성코드를 이용한 사이버 침해 행위를 방지하고자하는 노력을 해야할 것이다. 따라서 본 논문에서는 악성코드를 탐지하기 위해 실시간 시스템 모니터링 도구를 이용하여 악성코드가 시스템에 어떠한 침해행위를 행하고, 해당 침해 행위 모니터링 로그 분석을 통해 기존의 알려진 악성코드뿐만 아니라 알려지지 않은 악성코드를 탐지할 수 있는 악성 패턴 분석 및 추출에 초점을 두어 기술하였다.

Recently, there has been a growing interest in threat hunting presented to overcome the limitations of existing security solutions. Threat hunting is generally recognized as a technique for identifying and eliminating threats that exit inside the system. But, the definition is not clear, so there is confusion in terms with penetration testing, intrusion detection, and incident analysis. Therefore, in this paper, compare and analyze the definitions of threat hunting extracted from reports and papers to clarify their implications and compare with defense techniques.
