Information technology plays an important role in healthcare. The cloud has several applications in the fields of education, social media and medicine. But the advantage of the cloud for medical reasons is very appropriate, especially given the large volume of data generated by healthcare organizations. As in increasingly health organizations adopting towards electronic health records in the cloud which can be accessed around the world for various health issues regarding references, healthcare educational research and etc. Cloud computing has many advantages, such as "flexibility, cost and energy savings, resource sharing and rapid deployment". However, despite the significant benefits of using the cloud computing for health IT, data security, privacy, reliability, integration and portability are some of the main challenges and obstacles for its implementation. Health data are highly confidential records that should not be made available to unauthorized persons to protect the security of patient information. In this paper, we discuss the privacy and security requirement of EHS as well as privacy and security issues of EHS and also focus on a comprehensive review of the current and existing literature on Electronic health that uses a variety of approaches and procedures to handle security and privacy issues. The strengths and weaknesses of some of these methods were mentioned. The significance of security issues in the cloud computing environment is a challenge.

Now it is not useful the theory about civil-military relationship that have been analysed for power games between military and civilians Korean society is going on governance society managed by cooperating network of government, civilian society and business market These social change require for new context about civil-Military relationship. Military leadership must contribute desirable civil-military relationship This study will suggest the direction about military leadership for desirable civil-military relationship. Now political issues about military intervention to the government are almost settled, but the worry about complications between military and civilians exist in the part of low issues like policy-making. Another important issues is military leadership about the style of social-being. In recent years, social change is very complex and speedy like global networking and diversity, leadership environment also, changed like leadership paradigm shift. Military leadership must be examined from the principle to the context of social integration At the present age, individual soldier is citizen in uniformed. Also military leadership must to seek the principle in the citizen mind like citizenship. Another charactristics of present day military is influence of high technogy. For the high-tech war military need the transition about science and technology from the whole society. In the context of above the development of military leadership are suggested as follows. First, the development of military control leadership must besought to the context of cooperation between government and military. Government must provide the system to strengthen military professionals in the process of policy-making about national security Second, military leadership must embody the important social values through the advanced military making, Third, military leadership must provide the adaptability to the society through the military education of their soldiers Forth, military leadership must be contributed to the social integration and to the growing up individual soldiers like their socialization and their achievement. Five, an important subject of military leadership is the creation of desirable military culture through the harmony of social culture and military culture.

DHCP(Dynamic Host Configuration Protocol) is a protocol which dynamically allocates an IP address and/or host configuration parameters to a host. The DHCP client's address can be changed dynamically any time. For the possible communication with other system, the DHCP client has to inform its address to the DNS system with dynamic update facility. But the DNS dynamic update has a problem related to the security. So we proposed the efficient mechanism for the secure integration of DHCP and DNS by using DNS security extensions. The system also uses the DNS server as the certificate repository for the storing & retrieval of each other's certificate.

신경망은 주로 전체 데이터를 중앙에서 학습시키거나 상황에 따라 데이터나 모델을 나누어 분산학습 방법으로 처리해 왔다. 그러나 데이터의 양의 증가와 보안적 이유로 인해 모든 환경에서 기존의 방법을 쓰기에 어려움이 있다. 본 연구에서는 제한된 데이터만으로 모든 데이터로 학습한 것과 같은 학습 효과를 내기 위한 방법을 제안한다. 데이터의 구성이 다른 두 가지 환경인 V-환경과 H-환경에서 학습한 모델을 어떤 방법으로 통합해야 기존의 성능과 비슷한 성능을 낼 수 있는지 연구한다. 우리는 가중치를 합치는 방법을 avg, max, absmas 3가지 방법으로 실험하였으며, 실험 결과로 V-환경에서는 기존의 성능과 비슷한 성능을 보였으며, H-환경에서는 기존의 성능에는 부족하지만, 의미 있는 성능을 보였다.

Ensuring the security of Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS) is paramount to safeguarding the reliability and safety of critical infrastructure. This paper addresses the significant threat posed by reconnaissance attacks on SCADA/ICS networks and presents an innovative methodology for enhancing their protection. The proposed approach strategically employs imbalance dataset handling techniques, ensemble methods, and feature engineering to enhance the resilience of SCADA/ICS systems. Experimentation and analysis demonstrate the compelling efficacy of our strategy, as evidenced by excellent model performance characterized by good precision, recall, and a commendably low false negative (FN). The practical utility of our approach is underscored through the evaluation of real-world SCADA/ICS datasets, showcasing superior performance compared to existing methods in a comparative analysis. Moreover, the integration of feature augmentation is revealed to significantly enhance detection capabilities. This research contributes to advancing the security posture of SCADA/ICS environments, addressing a critical imperative in the face of evolving cyber threats.

Virtualization technology has been widely applied in the area of computer security research that provides a new method for system protection. It has been a hotspot in system security research at present. Virtualization technology brings new risk as well as progress to computer operating system (OS). A multi-level perception security model using virtualization is proposed to deal with the problems of over-simplification of risk models, unreliable assumption of secure virtual machine monitor (VMM) and insufficient integration with virtualization technology in security design. Adopting the enhanced isolation mechanism of address space, the security perception units can be protected from risk environment. Based on parallel perceiving by the secure domain possessing with the same privilege level as VMM, a mechanism is established to ensure the security of VMM. In addition, a special pathway is set up to strengthen the ability of information interaction in the light of making reverse use of the method of covert channel. The evaluation results show that the proposed model is able to obtain the valuable risk information of system while ensuring the integrity of security perception units, and it can effectively identify the abnormal state of target system without significantly increasing the extra overhead.
