There are so many study on Heumheum Sinseo as a lawbook. But the study on Heumheum Sinseo as investigation and forensic manual is uncommon. So this study was performed to find the value of Heumheum Sinseo as investigation and forensic manual. In Heumheum Sinseo, we could find the basic ideology of a sense of justice on humanitarianism and rationalism, and democratic thoughts on criminal law such as the presumption of innocence, speedy investigation clause and Limiting the admissibility of the confession. And so many scientific method on crime investigation are described in Heumheum Sinseo. We expect that this study serve as moment for us to be able to find it have 'practical' value to us.

정보저장매체에 저장된 디지털정보로부터 범죄 단서를 찾고, 법정에 증거로 제출하기 위한 일련의 활동을 일컫는 디지털 포렌식의 개념과 기법이 국내 수사기관에 도입되어 활용된 지 10여년의 시간이 흘렀다. 그러나 디지털증거라는 새로운 개념의 탄생은 최근까지 정보의 압수대상 여부 논란 등 수사실무에서의 혼란을 초래하고 있다. 기존 증거와 구별되는 디지털정보의 특성으로 말미암아 증거로 활용함에 있어 필요한 별도의 절차적 기술적 조건이 요구되고 있으나, 과거 규정과 지침만으로는 디지털증거를 취급함에 있어 해석, 처리의 혼선을 가져 왔으며, 아직 명확하고 구체적인 실무 지침과 규정은 마련되지 못하고 있는 실정이다. 디지털증거 확보체계는 이러한 혼선을 최소화하기 위해 디지털증거의 증거능력 유지를 위해 필요한 최소한의 요건을 정의하고, 이를 바탕으로 법정 제출시까지 동일성, 무결성과 이를 증명하기 위한 보관연속성(Chain of Custody) 등을 유지 관리하기 위해 수사기관간에 구축하고 있는 인프라 시스템이다. 본 고에서는 수사기관간의 디지털정보, 디지털증거 처리, 유통, 취급에 있어 문제점을 살펴보고, 이를 보완 개선하기 위한 그간의 노력과 향후 발전방향에 대해 고찰해 보고자 한다.

An area presenting new opportunities for both legitimate business, as well as criminal organizations, is Cloud computing. This work gives a strong background in current digital forensic science, as well as a basic understanding of the goal of Law Enforcement when conducting digital forensic investigations. These concepts are then applied to digital forensic investigation of cloud environments in both theory and practice, and supplemented with current literature on the subject. Finally, legal challenges with digital forensic investigations in cloud environments are discussed.

It is a current situation that a large number of physical and financial damages are increasing due to the growth of intellectual cyber crime and unexpected Internet incidents year by year. In the large scale security incidents, digital forensics techniques for computer crime investigations are essential to secure a place in the field. However, qualified digital forensics investigators who complete with digital security technology are practically insufficient in domestic. In this paper, as one of developing human resources plans regarding to scientific investigation of Internet security incidents, an undergraduate curriculum per stage in digital forensics was proposed. For the effective curriculum per stage, the interviews, group discussion on focused group of existing digital forensics investigators and related research were performed to select curriculum, and then the level of difficulty and practical suitability on each subject designed were analyzed through survey and interview to current investigators and security professionals. After collating the survey, the digital forensic curriculum per level was designed to highly adaptable workforce for the future for working and positive suggestions and proposals are addressed.

Hacking 공격자에 대한 수사실무에서는 Proxy Server를 연동한 해외에서의 우회공격에 대한 기법과 기술을 알아야 MAC address 또는 Real IP에 대한 역추적이 가능하다. 즉 Proxy Server를 여러 번 거치면서 자신의 Real IP를 숨기고 ARP Spoofing 기법을 사용하여 MAC address를 속이기 때문이다. 본 논문에서는 해외에서의 해킹 공격자들이 어떻게 공격자의 Real IP를 숨기고, ARP Spoofing 기법을 응용하여 공격을 시도하는 기법과 기술을 연구한다. 또한 Proxy Server를 통한 우회공격에서 ARP Spoofing 공격을 보안하는 방법을 연구한다. 본 논문 연구가 해외로 부터의 Hacking과 방어를 위한 기술 발전에 기여 할 것 이다.

Recently, police agency and social scientists' interest in the criminal profiling is increasing. Since serial killings had sharply increased during 1960s in U.S. the American law enforcement agency were pushed to solve those criminal incidents. Therefore, they drew various investigative techniques. But there are no study for the criminal profiling of arsonists. So, this paper reviewed prior studies on the arsonist's type and suggested how to apply this kind of basic information for investigating arson cases in Korea.

This study has aimed at establishing of the new administration scheme related to the goal of police like the investigation division through analyses of differences on the role perception of female police officers. In a related matter, work characteristics include ranks, working areas, working priods and the dependent variables of the role perception of female police officers are composed of 3 items like task role, group maintenance role and individual role. As a result, the differences by ranks, working areas, working priods that were analyzed by using one-way ANOVA showed significant differences in the each dependent variables. The results showed that the female police officers whose ranks were higher, who had been employed longer, and whose working areas were places where the cases occurred a lot more showed great point in mean value not only on task role but also on group maintenance role. The result of the study suggests a direction to achieve the best efficacy of police duties such as a criminal investigation, the prevention of crime and presents an useful indication to redefine the role.

This study aimed to compare effectiveness of fluorescent reagents for enhancing blood such as acid yellow 7, rhodamine 6G, eosin Y. AY7 and eosin Y have been introduced in Korea as fluorescent reagents for enhancing blood, but not rhodamine 6G. In this study, researchers photographed when each reagents gave the most effective results. Consequently, rhodamine 6G was superior to the others. Eosin Y enhanced bloody fingermarks weakly compared to AY7 and rhodamine 6G. Furthermore, the more depletion trials were done, the less effectiveness were shown. Therefore, researchers recommended that crime scene investigators try to use rhodamine 6G fluorescent reagents for enhancing blood.

Currently, under being related with confiscation method of digital store medium from the court of justice, "the sorting confiscation method of principle, the exceptional medium confiscation method" from in section3 no.106 of the criminal procedure code disregard the actual fields of investigation. What is more, there are many difficulties to execute cases by observing this for the achievement of confiscation purpose. At this point, I present the problems of the present confiscation search method and the desirable scene confiscation search method and the improvement program under the new technology circumstance.
