Recently, Interest variety of IT services and computing resources are increasing. As a result, the interest in the security of cloud environments is also increasing. Cloud environment is stored that to provide services to a large amount of IT resources on the Cloud. Therefore, Cloud is integrity of the stored data and resources that such as data leakage, forgery, etc. security incidents that the ability to quickly process is required. However, the existing developed various solutions or studies without considering their cloud environment for development and research to graft in a cloud environment because it has been difficult. Therefore, we proposed wire-wireless integrated Security management Model in cloud environment.

Recently, the introduction of Cloud Managing Security Services System to respond to security threats in cloud computing environments is increasing. Accordingly, it is necessary to analyze the security requirements for the Cloud Managing Security Services System. However, the existing research has a problem that does not reflect the virtual environment of the cloud and the data flow of the Cloud Managing Security Services System in the process of deriving the requirements. To solve this problem, it is necessary to identify the information assets of the Cloud Managing Security Services System in the process of threat modeling analysis, visualize and display detailed components of the cloud virtual environment, and analyze the security threat by reflecting the data flow. Therefore, this paper intends to derive the security requirements of the Cloud Managing Security Services System through threat modeling analysis that is an improved existing research.

Cloud computing-related security incidents have occurred recently are beyond the scope of a enterprise's security incident is expanded to the entire range of customers who use the cloud computing environment. The control technology for the overall integrated security of the cloud data center is required for this purpose. This study research integrated and additional security elements for the cloud data center control to understand the existing control technology. It is a better understanding of the IaaS cloud environment to build the IaaS cloud environment by CloudStack. SW-IaaS cloud structure by combining CloudStack and IaaS cloud model presented by NIST is proposed in this study. This paper derive a security framework to consider in each layer of The SW-IaaS cloud components, which are composed of the Cloud Manager, Cluster Manager, and Computer Manager.

딥러닝을 비롯한 인공기능과 영상처리 분야의 접목은 기존 물리보안의 기술적 한계를 뛰어넘어 새로운 기회의 장을 마련하고 있다. 하지만 딥러닝 기반 영상분석 기술도 지능형 영상감시가 필요한 실제 현장에서는 다양한 환경의 제약사항으로 인해 성능이 저하될 가능성이 높다. 본 논문에서는 실제 CCTV 환경의 영상 데이터를 확보하여 신경망을 이용한 지속적인 학습을 통해 영상분석의 성능을 개선하는 클라우드 기반 지능형 영상보안 플랫폼을 소개한다. 클라우드 기반 지능형 영상보안 플랫폼은 지자체 통합관제센터에서 수집한 CCTV 영상을 학습 데이터로 활용하여, 현장에서 신뢰받을 수 있는 사람 검출, 사람/차량 재식별, 열악 차량번호판 탐지 등의 지능형 영상분석 서비스를 제공할 수 있다.

Recently, the concept of zero trust has been introduced, and it is necessary to strengthen the security elements required for the next-generation security control system. Also, the security paradigm in the era of the 4th industrial revolution is changing. Cloud computing and the cybersecurity problems caused by the dramatic changes in the work environment due to the corona 19 virus continue to occur. And at the same time, new cyber attack techniques are becoming more intelligent and advanced, so a future security control system is needed to strengthen security. Based on the core concept of doubting and trusting everything, Zero Trust Security increases security by monitoring all communications and allowing strict authentication and minimal access rights for access requesters. In this paper, we propose a security enhancement plan in the security control field through a zero trust security model that can understand the problems of the existing security control system and solve them.

This study suggested the mobile intelligent management system based on the cloud service. The mobile intelligent management system are composed of cloud server, middleware and sensor networks. Each modules are controlled on mobile environment and observed operating status of each apparatus for environment. In this pater, the image-based moving detection algorithm applied in order to detect an intruder and average 12.3% are measured in moving detection experiments. it was confirmed the validity of the security device.

In this paper, we propose a reversely using the "Man In The Middle Attack" attack technique as a way to introduce network security without changing the physical structure and configuration of the existing network, a Virtual Network Overlay is formed with only a single Ethernet Interface. Implementing In-line mode to protect the network from external attacks, we propose an integrated control method through a micro network security sensor and cloud service. As a result of the experiment, it was possible to implement a logical In-line mode by forming a Virtual Network Overlay with only a single Ethernet Interface, and to implement Network IDS/IPS, Anti-Virus, Network Access Control, Firewall, etc.,. It was possible to perform integrated monitor and control in the service. The proposed system in this paper is helpful for small and medium-sized enterprises that expect high-performance network security at low cost, and can provide a network security environment with safety and reliability in the field of IoT and embedded systems.

The network separation environment is a network security design system that separates the internal business network from the external Internet network. It separates the internal business network from the external Internet by separating it into a business network that is not connected to the network to which the Internet is connected. The network is separated, and it is a relatively secure network structure compared to Danilman in terms of security. However, there are frequent cases of infecting internal networks by using vulnerabilities in internal systems, network devices, and security devices. In this paper, we analyze the vulnerability of IT security threats in such a network isolation environment and provide technical measures for effective security monitoring.

The use of open source has the advantage that the development environment is convenient and maintenance is easier, but there is a limitation in that it is easy to be exposed to vulnerabilities from a security point of view. In this regard, the LOG4J vulnerability, which is an open source logging library widely used in Apache, was recently discovered. Currently, the risk of this vulnerability is at the 'highest' level, and developers are using it in many systems without being aware of such a problem, so there is a risk that hacking accidents due to the LOG4J vulnerability will continue to occur in the future. In this paper, we analyze the LOG4J vulnerability in detail and propose a SNORT detection policy technology that can detect vulnerabilities more quickly and accurately in the security control system. Through this, it is expected that in the future, security-related beginners, security officers, and companies will be able to efficiently monitor and respond quickly and proactively in preparation for the LOG4J vulnerability.
