The occurrence of cyber crime is on the rise every year, and the security control center, which should play a crucial role in monitoring and early response against the cyber attacks targeting various information systems, its importance has increased accordingly. Every endeavors to prevent cyber attacks is being attempted by information security personnel of government and financial sector's security control center, threat response Center, cyber terror response center, Cert Team, SOC(Security Operator Center) and else. The ordinary method to monitor cyber attacks consists of utilizing the security system or the network security device. It is anticipated, however, to be insufficient since this is simply one dimensional way of monitoring them based on signatures. There has been considerable improvement of the security control system and researchers also have conducted a number of studies on monitoring methods to prevent threats to security. In accordance with the environment changes from ESM to SIEM, the security control system is able to be provided with more input data as well as generate the correlation analysis which integrates the processed data, by extraction and parsing, into the potential scenarios of attack or threat. This article shows case studies how to detect the threat to security in effective ways, from the initial phase of the security control system to current SIEM circumstances. Furthermore, scenarios based security control systems rather than simple monitoring is introduced, and finally methods of producing the correlation analysis and its verification methods are presented. It is expected that this result contributes to the development of cyber attack monitoring system in other security centers.

All measures related to the safety of the casino facilities guarantee safety of facilities that are targets of security guards, protect lives and properties, minimize risks of artificial and natural disaster and crimes. In summary, plan for responding to safety and accidents should be developed not only for the casino facilities but also for the facilities of annexed buildings, and lives and properties of customers and employees. Determine areas in the casino facilities that are prone to accidents and set around-the-clock guard in the areas or maintain surveillance with CCTV and prevent accidents through continuous patrol. These are the most basic and the most important requirements in safety. In addition, casinos which prompt gambling are causing economic and psychological treats to families. To resolve these social issues, casinos have adopted limited entrance system. To support this system, new forms of machine security systems such as video automatic recognition system of fingerprint pattern recognition system should be adopted too. In addition, security guards in casino facilities need to instill themselves with a sense of ownership as well as a strong sense of mission to do the best for customer security and to protect the company assets and employees and manage accidents that could occur without notice. Security guards should do their best to enable manage accidents that could occur without notice. Security guards should do their best to enable tourists who are on the rise due to increase in advanced country-style tourism and leisurely activities to get the utmost satisfaction from the casinos, and as a leader of private security company, establish the foundation for security based on the characteristics of security in Korea.

According to the recent statistics of Korean National Police which analyze the present status on the rate of the traffic accidents and their effects in Korea, the number of casualties by traffic accidents of 2004 amounted to 6,563, which means that the average number of casualties per 10,000 vehicles is 3.99. The figure of 3.99 is much larger than 1.85 of U.S.A, 1.10 of Japan, 1.14 of U.K., and 1.23 of Germany. The number of registered vehicles of Korea is steeply increasing since 1997 when it reached 10,000,000. Since then, the number of annual increase is estimated at 860,000 except for the year 1998 when the Korean economy was under the control of IMF, and over 14 million vehicles are registered as of the end of the year 2004. With the increase of vehicles, the violations of traffic rules, crimes using vehicles, car thefts, etc have been imposing a lot of serious problems on our society. On this thesis, we are aiming at analyzing some characteristics of traffic accidents reported to the police and suggesting some kinds of the police activities for securing the safety of the transportation.

우리나라는 세계 최고 수준의 IT 인프라를 기반으로 네트워크 및 서비스 융합, RFID 등 u-IT 서비스 확산 등을 통해 유비쿼터스 사회로 빠르게 진입하고 있다. 향후 디지털 융합이 가속화됨에 따라 시간과 공간의 제약 없이 원하는 정보의 획득 활용이 증가하고, u-Health, u-learning 등 IT가 타산업과 융합되면서 높은 부가가치를 창출할 것으로 전망 된다. 그러나 정보화의 급속한 진전에 따른 사회 전반의 편의성과 효율성이 향상하였으나, 해킹 바이러스, 개인정보 유출사고, 스팸 등 역기능으로 인한 피해도 확산되고 있다. 최근에는 네트워크 방어체계를 무력화시키는 지능화된 해킹, 대량의 고객정보 유출, 사회공학 기법을 활용한 피싱 등 이용자의 자산과 프라이버시를 침해하는 사이버범죄 증가 등으로 이용자자산과 권리 보호관점에서의 정보보호의 중요성이 부각되고 있다. 향후 시간과 장소에 상관없이 지식정보를 활용하여 편리하고 쾌적한 생활을 누리게 하는 지식정보사회는 예측 불가능한 위험이 곳곳에 산재한 정보위험사회로의 진입을 의미 할 수도 있다. 그러므로 미래사회에서 예상되는 위협을 예측하여 효과적으로 사전에 예방할 수 있는 체계를 마련하는 것은 안전하고 신뢰할 수 있는 지식정보사회를 향유하기 위한 전제조건으로 작용한다. 이에 본고에서는 미래 지식정보사회에 대비한 정보보호 전략으로 안전한 u-사회 청사진 설계 및 환경조성 선도와 국제화, 사이버위협 예방 및 대응체계의 입체적 조화와 융합, 정보보호 기술 제품 산업간 선순환 촉진과 성장 등 3대 전략을 설정하고 실행방안을 제시한다.

각종 사이버 범죄가 증가함에 따라 실시간 모니터링을 통한 사전 탐지 기술뿐만 아니라, 사후 원인 분석을 통한 사고 재발 방지 기술의 중요성이 증가하고 있다. 사후 분석은 시스템에서 생산된 다양한 유형의 대용량 로그를 기반으로 분석가가 보안 위협 과정을 규명하는 것으로 이를 지원하는 다양한 상용 및 오픈 소스 SW 존재하나, 대부분 단일 분석가 PC에서 운용되는 파일 기반 SW로 대용량 데이터에 대한 분석 성능 저하, 다수 분석가 간의 데이터 공유 불가, 통계 연관 분석 한계 및 대화형 점진적 내용 분석 불가 등의 문제점을 해결하지 못하고 있다. 이러한 문제점을 해결하기 위하여 고성능 인메모리 관계형 데이터베이스 시스템을 로그 스토리지로 활용하는 대용량 로그 분석 SW 개발하였다. 특히, 기 확보된 공격자 프로파일을 활용하여 공격의 유무를 확인하는 텍스트 패턴 매칭 연산은 전통적인 관계형 데이터베이스 시스템의 FTS(Full-Text Search) 기능 활용이 가능하나, 대용량 전용 색인 생성에 따른 비현실적인 DB 구축 소요 시간과 최소 3배 이상의 DB 용량 증가로 인한 시스템 리소스 추가 요구 등의 단점이 있다. 본 논문에서는 인메모리 관계형 데이터베이스 시스템 기반 효율적인 텍스트 패턴 매칭 연산을 위하여, 고성능의 대용량 로그 DB 적재 방법과 새로운 유형의 패턴 매칭 방법을 제안하였다.

The Korean real estate transaction makes a contract after the buying and selling person concerned agreed a business condition. As for vendee, business consists of the method that I issue documents before provision and money left over provision and the registration at the same time, and register a contract deposit in vendor. However, it latent for the real estate transaction various accidents such as fraud from a contract day to time to finish a real estate registration transfer, embezzlement, double contract by the breach of trust. Nevertheless vendee comes to match vendor by an asymmetry of the information one-sidedly to the front completing a registration transfer. I may prevent stellionate by the breach of trust of vendor if I use an ESCROW system in such a responsibility blank state.

Abnormal navigating ships affact the ships navigating normal routes seriously. So VTS centers and Korean Coast Guard co-work(cooperate) closely to trace the ships which break the regulations and make accidents. But it is evident that there is limitations to indetify the risk factors caused by men. Unfortunately there is very few of the researches on the identificaton of risk elements by men. This paper is to implement the intelligent system for identifying abnormal navigating ships by using fuzzy inference.
