Today's Internet of Things (IoT) has had a dramatic increase in the use of various daily aspects. As a consequence, many homes adopt IoT technology to move towards the smart home. So, the home can be called smart when it has a range of smart devices that are united into one network, such as cameras, sensors, etc. While IoT smart home devices bring numerous benefits to human life, there are many security concerns associated with these devices. These security concerns, such as user privacy, can result in an insecure application. In this research, we focused on analyzing the vulnerabilities of IoT smart home cameras. This will be done by designing a new model that follows the STRIDE approach to identify these threats in order to afford an efficient and secure IoT device. Then, apply a number of test cases on a smart home camera in order to verify the usage of the proposed model. Lastly, we present a scheme for mitigation techniques to prevent any vulnerabilities that might occur in IoT devices.

Data and network security for e-Healthcare Systems are a primary concern due to the easiest deployment area accessibility of the sensor devices. Furthermore, they are often interacting closely in cooperation with the physical environment and the surrounding people, where such exposure increases security vulnerabilities in cases of improperly managed security of the information sharing among different healthcare organizations. Hence, healthcare-specific security standards such as authentication, data integrity, system security and internet security are used to ensure security and privacy of patients' information. This paper discusses security threats on e-Healthcare Systems where an attacker can access both data and network using masquerade attack. Moreover, an efficient and cost effective approach for countermeasures is discussed for the delivery of secure services.

Protection activity is divided by the security measures of preventive action and immediately protective reaction in case of emergency situation. The purpose of this study is to emphasis the importance of prevention when providing security for protectees. What I suggested in this thesis is summarized below. Chapter I which sets out purpose, concept, general remarks are followed 3 steps for conducting security action by Chapter II. Chapter III concerns the classification, security technic of preventive action. Classified involving security information, security action, security measures. It is followed site survey, security plan, detailed procedures, coordinative meeting, previous security action, protective action, review meeting by protective technic. Chapter IV consider effective counter plan method of preventive action. Chater V, conclusion.

In recent, Open markets are booming up rapidly. Open markets are one of the online marketplaces which mainly concentrated on spot transactions of commodities, and are differentiated from integrated internet shopping stores with market participants, trading rules and so on. This study investigated on factors affecting satisfaction with and preference on open markets by comparing open markets with integrated internet shopping stores, and aimed to figure out the reasons why open markets are growing up so rapidly and to forecast the future of open markets. To investigate the factors affecting buyers' satisfaction with and preference on internet shopping channel. I extracted several factors through literature reviews. The factors include the pros (cost saving and time saving), the cons (security concerns and privacy concerns), and decision making support suggested by Simon's research as well. Then, I constructed research model and related research hypotheses. To verify research hypotheses, I conducted field survey targeting on online buyers and analyzed research data using structural equation model. According to data analysis result, open markets have competitive advantages over integrated internet shopping stores with respect to cost saving, time saving, and decision making support. However, online buyers are still concerning privacy issues within open markets. In summary, buyers are considering that open markets are cheaper, faster, and more efficient internet shopping channel, compared with integrated internet shopping stores. However, open markets are required to dedicate to lessen buyers' privacy concerns to rebirth as more satisfying and preferable internet shopping channel and to prosper in the future.

Software Defined Networking (SDN) is a novel approach that have accelerated the development of numerous technologies such as policy-based access control, network virtualization, and others. It allows to boost network architectural flexibility and expedite the return on investment. However, this increases the system's complexity, necessitating the expenditure of dollars to assure the system's security. Network Function Virtualization (NFV) opens up new possibilities for network engineers, but it also raises security concerns. A number of Internet service providers and network equipment manufacturers are grappling with the difficulty of developing and characterizing NFVs and related technologies. Through Moodle's efforts to maintain security, this paper presents a detailed review of security-related challenges in software-defined networks and network virtualization services.

RFID technology can help automatically and remotely identify objects, which raises many security concerns. We review and categorize several RFID security and privacy solutions, and conclude that the most promising and low-cost approach currently attracts little academic attention. We therefore concluded that, from a privacy perspective, the user scheme is an important strategy for meeting the consumer's needs. Furthermore, we call for the privacy research community to put more effort into this line of thinking about RFID privacy.

I study on the classification of cyber terror & counterplan against cyber terror The paper, purporting to consider security counterplans, comprise five chapters. Chapter I which introduction is followed by chapter II, dealing largely with the general definition and classification of cyber terror. Chapter III concerns the domestic & foreign cases of damages by cyber terror. Chapter III consider the condition of world nations against cyber terror and its actual condition. It is followed by concluding observation made in chapter V.

In this paper, we analyses of additive crypto-module architecture for a sensor network. Recent research in sensor networks has raised security issues for small embedded devices. Security concerns are motivated by the development of a large number of sensor devices in the field. Limitations in processing power, battery life, communication bandwidth and memoryconstrain devices. A mismatch between wide arithmetic for security and embedded data buscombined with lack of certain operations. Then, we compared the architecture of crypto-module in this paper.

This paper is concerned with the influence in the job satisfaction by the organization, the job specialty and the self-devotion in the special duty of private security. Today's society is required more intensive security in the diversity, the complexity and the uncertainty, but the public security service could not supply enough for what the society requires. In this circumstance more specialized and special trained security services are demanded from private security industry. With the concerns, this study is based on actual survey. The study is telling us that there is much relationship in job satisfaction between each element. Which means that 1) there is some different from personality, 2) there is much influence in self-devotion by job specialty, 3) there some effectiveness in job satisfaction by job specialty, 4) there is some influence in job satisfaction by self-devotion, and 5) job satisfaction is affected by job specialty and self-devotion.
