Security Evaluation System is a system that evaluates the security of the entire enterprise network domain which consists of various components and that supports a security manager or a Security Management System in making decisions about security management of the enterprise network based on the evaluation. It helps the security manager or the security management system to make a decision about how to change the configuration of the network to prevent the attack due to the security vulnerabilities of the network. Security Evaluation System checks the “current status” of the network, predicts the possible intrusion and supports decision-making about security management to prevent the intrusion in advance. In this paper we analyze the requirements of the Security Evaluation System that automates the security evaluation of the enterprise network which consists of various components and that supports decision-making about security management to prevent the intrusion, and we propose a design for it which satisfies the requirements.

In our current information focused society, information is regarded as a core asset and the leakage of customers' information has emerged as a critical issue, especially in financial companies. It is very likely that the technology that safeguards which is currently in commercial use is not focused at an enterprise level but is fragmented by function or by only guards portions of a customer's personal information. Therefore, It is necessary to study the systems which monitor the indicators of access at an enterprise level in order to preemptively prevent the compromise of such data. This study takes an enterprise perspective on such systems for a financial company. I will focus on examination of the methods of implementation of the monitoring system, the application of pattern analysis and examination of Security Risk Indicators (SRI). A trial of the monitoring system provided security managers and related departments with proper screening capabilities of information. Therefore, it is possible to establish a systemic counter-plans based on detectable patterns.

As new information technology emerges, companies are introducing an Enterprise Security Management system to cope with new security threats, reducing redundant investments and waste of resources and counteracting security threats. Therefore, it is necessary to construct a security evaluation metric based on related standards to demonstrate that the Enterprise Security Management(ESM) System meets security. Therefore, in order to construct a metric for evaluating the security of the ESM, this study analyzed the security quality related requirements of the ESM and constructed a metric for measuring the degree of satisfaction. This metric provides synergies through the unification of security assessments that comply with ISO/IEC 15408 and ISO/IEC 25000 standards. It is expected that the evaluation model of the security quality level of ESM will be established and the evaluation method of ESM will be standardized in the future.

In this study, divide by a private enterprise and army, 2 organizations about observed priority item among administrator, service provider, user viewpoint about the information security item for smartwork activation and in 3 steps hierarchic according to AHP technique analyzed and decided priority for information security observance item. As a result, importance difference could confirm identified by administrator, service provider, user viewpoint period of about information security observance item recognizing in a private enterprise and army.

With the wide usage of internet in many fields, networks are being exposed to many security threats, such as DDoS attack and worm/virus. For enterprise network, prevention failure of network security causes the revealing of commercial information or interruption of network services. In this paper, we propose a method of prevention of DDoS attacks for enterprise network based on traceback and network traffic analysis. The model of traceback implements the detection of IP spoofing attacks by the cooperation of trusted adjacent host, and the method of network traffic analysis implements the detection of DDoS attacks by analyzing the traffic characteristic. Moreover, we present the result of the experiments, and compare the method with other methods. The result demonstrates that the method can effectively detect and block DDoS attacks and IP spoofing attacks.

Corporation's computerization developed by diffusion of internet, and dysfunction of Information is increasing greatly with virus, computing network infringement. Therefore, the today, corporation security is more and more emphasized. Security solution by that importance of security rises so is developing together Security solution is developing to ESM system in existing single system and important thing is function of each security solution and optimizing design of policy. Existent security policy taking a serious view security from external invasion but security of interior the importance rise the today. Accordingly, must construct ESM system of new structure for this. This paper proposes and embodied integration security administration system that solidify interior security utilizing IDS. Experiment external IP and ID access and analyzed the result.

컴퓨터 포렌식절차에서 증거물 획득은 중요한 부분이다. 컴퓨터 포렌식의 여러 원칙 중 신속성의 원칙은 휘발성 정보의 획득유무와 관계가 있다. 기존 통합보안관리시스템(ESM: Enterprise Security Management) 은 보안이벤트중심으로 정보를 수집한다. 컴퓨터 포렌식에서 중요한 휘발성 시스템 포렌식 정보와 네트웍 포렌식 정보는 수집하지 않는다. 본 논문에서는 통합보안관리시스템에 Pre-Forensic 정책을 도입하여 기존 보안경보기능에 포렌식 데이터 수집 대응방안을 추가한 새로운 통합 보안관리시스템 모델을 제안한다. 제안 시스템은 무결성이 보장되는 많은 증거를 수집할 수 있으며 향상된 컴퓨터 포렌식 증거물 획득 방법을 제시한다.

Information-security management systems (ISMSs) are becoming very important, even for micro, small, and medium enterprises (MSMEs). However, implementing an ISMS is not an easy task. Many obstacles must be overcome, e.g., complexity, document tracking, competency management, and even changing cultures. The objective of our study is to provide ISMS application tools, based on ISO 27001:2013 ISM frameworks. The application was developed on the Odoo Open Enterprise Resource Planning platform. To validate its feasibility for future improvement, the application was implemented by an MSME company. For this implementation, information-security-related users gave their feedback through a questionnaire. The distributed feedback questionnaire consists of nine assessment parameters, covering topics from the application's technical aspects to users' experiences. Based on the questionnaire feedback, all users of the application were satisfied with its performance.

There are many information objects and users in a large company. It is important issue how to control users access in order that only authorized user can access information objects, Traditional access control models do not properly reflect the characteristics of enterprise environment. This paper proposes an improved access control model for enterprise environment. The characteristics of access control in an enterprise are examined and a task role-based access control(T-RBAC) model founded on concept of classification of tasks is introduced. T-RBAC deals with each task differently according to its class, and supports task level access control and supervision role hierarchy.

통합보안관리시스템(Enterprise Security Management)은 기업의 보안 정책을 기반으로 다수의 보안시스템을 중앙에서 통합관제, 운영, 관리를 지원하는 시스템이다. 국내의 경우 정보보호시스템에 대한 보안성 평가는 국제공통평가기준을 근거로 평가 및 인증이 이루어지고 있는 반면, SW 품질관점에서의 ESM에 대한 평가 방안에 대한 연구는 미미한 실정이다. 이에 따라 본 논문에서는 SW 품질관점에서 ESM에 대한 평가항목을 제안하고자 한다.
