Recently software security of the smart phone is an important issue in the field of information science and technology due to fast propagation of smart technology in our life. The smart phone as the security critical systems which are utilizing in terminal systems of the banking, ubiquitous home management, airline passengers screening, and so on are related to the risk of costs, risk of loss, risk of availability, and risk by usage. For the security issues, software hazard analysis of smart phone is the key approaching method by use of observed failures. In this paper, we propose an efficient integrative framework for software security analysis of the smart phone using Fault Tree Analysis (FTA) and Failure Mode Effect Analysis (FMEA) to gain a convergence security and reliability analysis technique on hand handle devices. And we discuss about that if a failure mode effect analysis performs simpler, not only for improving security but also reducing failure effects on this smart device, the proposed integrative framework is a key solution.

A established military security tast based on existing manual and off-line needs the change and development to support effective and systematic task performance according to environment change of informational and scientific project in the military. Therefore this study suggests to set up the standard model of the defense integrated security system to automate and informationize major defense security task based on actual and problem in the area of major defense of security task and case analysis of these in America, England and other countries. The standard model consist of unit systems were made up integrated security system, security management system, man entrance system, vehicle entrance system, high-tech guard system, terror prevention system and the security accident analysis system, and this suggested model based on possible technology and system. If this model is apply to each real military unit, we will expect the development of defense security.

최근에 발생한 3.20 사이버테러와 6.25 사이버테러와 같이 특정 방송사와 금융권 전산망을 마비시키고 임직원 시스템을 망가뜨려 못쓰게 만드는 피해 유형이 발생되고 있다. 이런 사이버 공격에 사용되는 악성코드에 대해서 탐지에서 분석 그리고 검증 단계를 통합적으로 모니터링하고 필터를 통해 악성코드를 추출하고 차단하는 시스템 개발이 필요하다. 본 논문에서는 실시간으로 악성코드를 탐지하는 엔진들의 분석 및 검증 현황을 확인하고 실시간 통계 모듈에서 수집한 자료들을 바탕으로 향후 보안 정책 방향 및 미래 예측을 계획할 수 있는 실시간 악성코드 분석 통합 관리 시스템을 제안한다.

The Internet has evolved into the global computer network due to the openness of its protocol, but such evolution brings about new risks and threats. To protect computer networks safely, it is the best way that preventing an attacher from intruding beforehand. However, to provision against all attacks causes the degradation of network performance as well as to prevent unknown attacks is very hard. Secure Combination, the framework which establishes a mutual collaboration and cooperation between the trusted zones, could protect systems from the potential attacks. This frameworks can predict attacks by exchanging security information and cooperating with each zone. It is a dynamic and powerful security architecture that rapidly enables updating security policy and deploying response modules.

This paper describes an Security Manager that integrally manages the Information Service related to RFID middleware, Object Name Service, and Web Service for upper level applications. In order to provide the access control of distributed RFID objects, Single-Sign-On has been implemented by extending existing UCON (Usage Control) model and SAML (Security Assertion Markup Language) assertions. The security technology of distributed RFID systems can be included in middleware and protect RFID information. In the future, it can be also applied to ubiquitous sensor networks.
