What is an alternative to medical information security of medical information more secure preservation and safety of various types of security threats should be taken, starting from the software design. Interspersed with medical information systems medical information to be able to integrate the real-time exchange of medical information must be reliable data communication. The software architecture design of medical information systems and sharing of medical information security issues and communication phase allows the user to identify the requirements reflected in the software design. Software framework design, message standard design, design a web-based inter-process communication procedures, access control algorithm design, architecture, writing descriptions, evaluation of various will procedure the establishing architecture. The initial decision is a software architecture design, development, testing, maintenance, ongoing impact. In addition, the project will be based on the decision in detail. Medical information security method based on the design software architecture of today's medical information security has become an important task of the framework will be able to provide.

In this paper, we propose an architecture design of military operation system utilizing cellular networks. The main contribution of this paper is to provide a cost-effective military operation solution for ground forces, which is based on IT(information technology). By employing the cellular phones of officers' and non-commissioned officers' as the tools of operational communication, the proposed system can be constructed in the minimum duration and be built on the four components: command and control system, gateway, security system, and terminal(cell phone). This system is most effective for the warfare of limited area, but the effectiveness does not decrease under the total war covering the whole land of Korea. For the environmental change of near future, expanded architecture is also provided to utilize the functionalities of smart phones.

Automotive Theft has been an obstinate problem around the world. Design and manufacture of anti-theft systems have become more and more complex due to the rise in complexity of theft in the system. Most of the anti-theft systems available in the market, are the alarm types which audibly deter some thieves away but do not prevent one's car from being stolen and even are not good enough to meet the growing complexity of theft in the country. This paper presents a simple and an efficient anti-theft system which provides improved security by the use of efficient access mechanisms and immobilization systems. This security system can immobilise an automobile and its key auto systems through remote control when it is stolen. It hence deters thieves from committing the theft. It also effectively prevents stealing of key auto systems for reselling by introducing four layers of security features written in the form of firmware and embedded on the Electronic Control Units (ECUs). The particulars of system design and operation are defined in the paper. The experimental outcomes show that this system is practicable and the owner can steadily control his vehicle within a few seconds.

RFID/USN is important infrastructure of the ubiquitous society. And so, It is various and practical research is attempted. These two base technology have physical characteristic and complement relationship. Like this relationship is applied Following example that is system research which manages warehouse stocks and conditions. First, We adhere RFID Tag at the Pallet of the warehouse and do identification goods. And then, It grasps the environment state information of stocks with sensor module which has Zigbee wireless communication function. From like this process RFID Tag information and jop-control command of sensor node also it is exposed to air. Therefore, We control sensor node in USN/RFID environment through the mobile device. And system design for the security Apply of the process is main purpose of this paper's. We propose the condition and function of the mobile device to the secondary. And We define the relation of the sensor node with RFID to be arranged to a warehouse. Finally, This paper is designed to find a trade-off of the following viewpoints. First, We offer suitable sensor-control information to a actual manager. Second, We offer RFID tag security approach to control the action of the sensor. Third, It increases the survivability of sensor node form.

In this paper a design and implementation method of remote control system for automobile is presented. For this, we used the Bluetooth technology for remote and wireless communications and microcontroller for system control. By using these techniques, we can design and implement automobile remote control system to improve data error rate, security and application.

This paper proposes security architecture, security audit framework, and audit check item. These are based on the security requirement that has been researched in the information system audit. The proposed information security architecture is built in a way that it could defend a cyber attack. According to its life cycle, it considers a security service and security control that is required by the information system. It is mapped in a way that it can control the security technology and security environment. As a result, an audit framework of the information system is presented based on the security requirement and security architecture. The standard checkpoints of security audit are of the highest level. It was applied to the system introduction for the next generation of D stock and D life insurance company. Also, it was applied to the human resources information system of K institution and was verified. Before applying to institutions, system developers and administrators were educated about their awareness about security so that they can follow guidelines of a developer security. As a result, the systemic security problems were decreased by more than eighty percent.

This paper proposes a new implementational model based on the security model of Oracle for Web ontology. Recently, several access control models using relational database security model for access control to Web ontology have been developing, and one of the most representative access control model is the RAC model. However, the RAC model is based on the standard security model, and thus it does not provide a implementational model for practical relational database management systems. In this paper, we propose an implementational model based on Oracle which is widely used and providing various security policies. This paper shows the implementation and experimental evaluation. Especially, the proposed model uses the VPD security model of Oracle and support high application and usability.

Recently, various threat and security incident are occurred for unspecified individuals, and this problem increases as the rapid of information sharing through Internet. The using of Information Security System such as IDS, Firewall, VPN etc. makes this problem minimal. However, professional knowledge or skill is needed in that case, normal user can't operate the Information Security System. This paper designs and implements File Access Control Module(FACM) to use easily for normal user against malicious threats and attacks. The FACM can exclude from malicious threats and attacks based on operation system rather than detection of threats and attacks. The FACM is working not only Windows System but also Linux System, and the FACM has effect on access control, integrity and non-repudiation for a file with an access control over files on the each OS that are used by multi-user.

지난 5년간 대표적인 산업제어시스템(Industrial Control System)인 국내 원자력 발전소에 대한 해킹 시도는 총 1,843회로 사이버공격에 대한 위험은 날로 높아지고 있다. 이러한 공격은 사이버전, 테러, 사이버범죄자들에 의해 실행되고 있다. 이러한 위험을 통제하기 위해서는 산업제어시스템이 일반적인 IT시스템과 다른 운영체제, 네트워크 등 시스템 환경을 고려하여야 한다. 본 논문에서는 기존의 IT보안 대책과 산업제어시스템 보안 대책을 비교 분석하고, 국내외에서 발생하고 있는 산업제어시스템에 대한 공격 사례를 비교 분석하여 산업제어시스템 인프라에서 고려하고 통제해야 할 정보보호 요소들을 제언한다.

When computer systems with mandatory access control mechanism are interconnected each other for enforcing the MHS(Message Handling System) security on the multilevel secure distributed network environment, illegal information flow may occurs due to the unexpected cascade vulnerability problem. In this paper, new MHS security policy and security property functions are proposed for preventing the cascade vulnerability.
