As the situations that important evidences or clues are found in digital information devices increase, digital forensic technology is widely applied. In this paper, forensic based audit system is implemented by associating forensic analysis system with agent system which monitors and collects data for analysis in storage devices over distributed network nodes. Forensic audit system implemented in this paper can prevent, audit and trace the computer related crimes in IT infrastructure by real time monitoring and evidence seizure.

Audit system of local self-government has a problem in many sectors, for the development of local autonomy, improvement of these issues is essential. The purpose of this study was to improve the present problems by looking at the problems of local governments audit system. The problem with local governments audit system are as follows. First, the non-efficiency and redundancy of internal and external audit exist. Second, in terms of audit organization and mechanism of local government, independence is deficient. Third, the expertise is lacking in terms of audit personnel. Fourth, it is insufficient effectiveness ensure regarding the processing of the Audit Office at the time and results. Improvement plan of the problems of local governments audit system are as follows. First, the unification of the country and local governments of the audit and there is a need to establish a legal system on the local audit. Second, the establishment of independent internal audit mechanism for ensuring the independence of the internal audit mechanism. Third, introducing a variety of personnel system related to the human resources of audit personnel and there is a need and strengthening of education and training to the audit personnel. Fourth, the public of the audit, community participation, and etc results in the effectiveness and democratic ensuring of audit.

The existing aiming inspection use foreign-made aiming inspection equipment. However, the quantity is insufficient and the difficult to maintain. So it takes a lot of time to inspect the target. This system can reduces the time of aiming inspection and be maintained and distributed smoothly because it is a domestic product. In this paper, we develop a system that can detect targets and monitor shooting results through a target detection deep learning model. The system is capable of real-time detection of targets and has significantly increased the identification rate through several preprocessing of distant targets. In addition, a graphical user interface is configured to facilitate user camera manipulation and storage and management of training result data. Therefore the system can replace the currently used aiming inspection equipment and non-fire training.

Recently, performance auditing system of governmen is carried out as most promising framework of government audit. Performance audit by the Board of Audit and Inspection of Korea involves assessing the causes and effects of government policies, programs, and Institutions with the criteria of economy, efficiency, effectiveness. Performance auditing will contribute to strengthening the values of objective assessments of whether public resources are responsibly and effectively managed to achieve intended results. Nevertheless, there seems to be a problems appears in implementation of audit. That is the problems of tendency return to legitimacy audit which is result from the lack of strong approach and methodology. So, this study purpose to developing stronger audit concepts and methods that add to the process and framework of traditional performance auditing system. First, this study evaluates the limitation of current performance auditing system with the perspective of systems thinking. Second, this study analyzes the process and method of current system and develop the conceptual model of the Dynamics Audit System using the system dynamics methodology, which focused on the appropriate auditing process and framework.

With the spread of COVID-19 infections, the need for next-generation learning management system for undact education is rapidly increasing, and the Ministry of Education is planning future education through the establishment of fourth-generation NEIS. If the fourth-generation NEIS System is well utilized, there are advantages such as providing personalized education services and activating the use of educational data, but a solution to the illegal access problem in an access control environment where strict authorization is difficult due to various user rights. In this paper, we propose a blockchain-based access control audit system for next-generation learning management. Sensitive personal information is encrypted and stored using the proposed system, and when the auditor performs an audit later, a secret key for decryption is issued to ensure auditing. In addition, in order to prevent modification and deletion of stored log information, log information was stored in the blockchain to ensure stability. In this paper, a hierarchical ID-based encryption and a private blockchain are used so that higher-level institutions such as the Ministry of Education can hierarchically manage the access rights of each institution.

RDB나 기존의 ISAM 파일이 검색과 저장의 효율성이 높을지라도 다양한 형태의 자료 저장 능력과 프로그래밍의 효율성 부족에 대한 대안으로 객체지향 프로그래밍과 객체 지향 DB의 활용이 확대되고 있는데 1996년, 미국의 경우 활용기업의 비율이 15%정도에 이르며 증가추세에 있는 것으로 나타났다. 본 연구는 OOP, OODB를 EDP 감사의 관점에서 연구하는 것으로 전통적 EDP 감사도구와 기법을 객체지향모형에 적용가능한지와 적용시에 예상되는 문제점을 검토하려는 것이다. 주요한 EDP 감사도구와 기법중 입출력에 초점을 두 는 Test Data, Integrated Test Data/Facility에는 적용이 비교적 쉽지만 처리과정에 초점을 두는 Embeded Audit Module, GAS 등에는 구현을 위한 메소드의 수정이나 설치상의 문제 가 큰 것으로 보인다. 그러므로 GAS를 구현할 때 감사모듈을 설치하는 절충법이 필요한 것 으로 보인다.

In general, operating system is offering the security function of OS level to support several web services. However, it is true that security side of OS level is weak from many parts. Specially, it is needed to audit/trace function in security kernel level to satisfy security more than B2 level that define in TCSEC(Trusted Computer System Evaluation Criteria). So we need to create audit data at system call invocation for this, and do to create audit data of equal format about almost event and supply information to do traceback late. This Paper Proposes audit/trace system module that use LKM(Loadable Kernel Module) technique. It is applicable without alteration about existing linux kernel to ensure safe evidence. It offers interface that can utilize external audit data such as intrusion detection system, and also offers safe role based system that is divided system administrator and security administrator These data will going to utilize to computer forensics' data that legal confrontation is Possible.

Recently, information technology is considered as a basement of management for industries as well as administrations. Especially, government agencies deal with more high sensitive and Important data than other businesses, so, their security managements should be fair and efficient. At present, most government agencies possess and operate their own information security systems, but apply them for the sake of formality only, even do not adapt an audit system for management polices. This paper presents a design and implementation of an automated audit system which is suitable for the operation environment in government agencies, using the audit system based on the BS7799. The. proposed system aims to objectively, numerically and daily control the ISMS (Information Security Management System) for different level of government agencies. In addition, it permits to design and implement an adaptive audit tool, in order to meet a given condition of audit organization and guard the personal relationship between the auditor and its counterpart.
