산업제어시스템에 침해사고가 발생하여 서비스 제공이 중단될 경우 사회에 큰 혼란을 야기할 수 있기 때문에 주기적으로 내부 자산의 보안 수준을 관리하는 것은 매우 중요하다. 위 논문은 산업제어시스템 내부 자산의 보안성 확립을 위한 산업제어시스템 자산 유형별 보안성 평가 프로그램을 제안한다. 동일 자산 그룹에 따라 보안조치를 선별적으로 적용하고 신규 취약점을 지속적으로 파악하는 프로세스를 프로그램에 적용하여 제어시스템 보안 수준을 안정적으로 유지하는 사내 프로그램으로 활용될 수 있도록 한다.

The risk analysis's aim is analyze the risk for the asset of organization with asset assessment, vulnerability assessment, threat assessment. existing TTA risk analysis methodology model propose to overall flow, but can not propose to detail behavior or each level. That is, step of risk analysis is insufficient in classification of threat and detail proposal of considered the risk with classified threat. So this paper propose that analysis and evaluate the vulnerability and threat assessment with determinated quantity. this paper consider current national information system and threat of environment and technology. So can estimate the risk with determinated quantity. Finally, analyze the asset risk of organization.

Current situations, such as IMF crisis, WTO agreement and decrease of construction market, demand changes to construction companies. To meet the situation, they focus on the value of the intangible assets to improve their competitive power. In Korea, Various institutes estimate the construction company in accordance with their Purposes. But their estimating method has limitations to know the potential value of the company because they don't much concentrate on characteristics of construction industry and intangible assets. This study was peformed to introduce the methodology of estimating intangible assets of company and to show the state of intangible asset of major construction companies in Korea. Market Capitalization Method(MCM) was used to calculate intangible assets and all data are based on Annual Business Report.

This study aims at establishing the decision-making support system for the highway assets, long-term performance presumption and evaluation of asset value, which are appropriate for Korea, and proposing the methods of the optimal engineering method and the timing decision for the preventive maintenance through the project evaluation, the optimization method and life-cycle analysis related to the highways. In order to supplement the current problem of the near-sighted budget management system, which chooses the maintenance place of the highway, depending on the level of the budget with fixed amount, the long-term required budget prediction system and the economy principle were introduced, so that the pavement agency can predict the level of the required budget, and it was aimed to develop the pavement asset evaluation system to maintain the performance of the highway with the minimum of the cost. In the use of the highway pavement asset evaluation system, to maintain the appropriate level of the pavement evaluation index, when the budget was efficiently established in the reference of the required maintenance budget for the chosen section of the highway in the year concerned, it was possible to analyze the most rational pavement maintenance budget. With this result, it is estimated to prevent the unnecessary waste of budget in advance, and through the development of the decision-making system for the long-term performance presumption and the asset value estimation of the pavement, it is expected to able to analyze the previous evaluation of the project related to the highway and the feasibility of introduction.

카네기멜론 대학의 SEI(Software Engineering Institute)는 개인 의료 정보의 보안을 규정한 HIPP A(Health Insurance Portability and Accountability Act)의 조항을 미 국방부(DoD)가 제청하면서 직면하게 된 보안 준수의 난항을 해결하기 위해서 TATRC(Telemedicine and Advanced Technology Research Center)와 공동으로 자산 식별 및 정보보호 위험평가를 위한 방법론인 OCTAVE를 개발하였다. 이후 조직의 운영 과정에서 발생하는 위험의 내성을 높이기 위한 질적 위험평가 기준이 개발되었으며 이를 통해 조직의 중요한 자산 및 잠재적 위협과 취약점을 식별하는 위험평가 방법으로 발전하였고, 2005년에는 100명이하의 소규모 조직에 적합한 OCTAVE-S가 발표되었다. 오늘날 급변하고 있는 IT 환경에서 기존의 OCTAVE 보다 간소화되고 최적화된 위험평가 프로세스를 제공하기 위해서 2007년에 OCTAVE Allegro 프레임워크가 개발되었다. 본고에서는 기존의 OCTAVE 방법론의 주요 특정을 살펴보고, 정보자산 중심의 OCTAVE Allegro 위험 평가 방법론을 소개한다.

본 논문에서는 기존의 기술가치평가모형들을 검토하여 문제점과 한계를 찾아내고, 이를 극복할 뿐만 아니라, 기술의 실제가치에 접근하고자 새로운 시도를 하였다. 먼저 1단계에서는 DCF 모형을 이용하여 사업가치를 계산하고, 2단계에서는 사업가치에서 무형자산이 차지하는 비율이 산업별로 서로 다를 것이라는 가정아래 사업가치 창출에 대한 무형자산의 기여도를 구했다. 그리고 3단계에서는 전체 사업가치 창출에서 기술의 기여가 차지하는 비중을 측정하는 기술의 기여도를 구했다. 이렇게 3단계에 걸쳐 얻은 결과를 동시에 고려하여 기술가치를 산출하였다. 그리고 마지막 4단계에서는 전 단계에서 고려되지 못했던 미래수익 창출의 불확실성을 반영하기 위해 실물옵션모형을 적용하였다. 이와 같이 평가과정을 4단계로 구분하고, 각 단계별로 평가의 특성에 맞는 방법을 채택함으로써, 기존의 평가모형이 가지고 있었던 문제점과 한계를 극복하고, 불확실성이 높은 기술자산의 실제가치에 보다 근접할 수 있었다.

Cyber Mission Impact Assessment is one of the essential tasks which many militaries and industrial major companies should perform to effectively achieve their mission. The unexpected damage to an organization's assets results in damage to the whole system's performance of the organizations. In order to minimize the damage, it is necessary to quantify the available capacity of the mission, which can be achieved only with the remaining assets, and to immediately prepare a new second best plan in a moment. We therefore need to estimate the exact cyber attack's impact to the mission when the unwanted damage occurs by modeling the relationship between the assets and the missions. In this paper, we propose a new model which deals with the dependencies between assets and missions for obtaining the exact impact of a cyber attack. The proposed model distinguishes task management from asset management for an efficient process, and it is implemented to be optimized using a vectorized operation for parallel processing and using a buffer to reduce the computation time.

Because bridges can cause more significant damage than other infrastructure a certain level of safety shall necessarily be secured for users. As most of bridges' service life become 20-30 years there will be a dramatic increase in the maintenance and repair cost but the budget and human resource will be limited. Asset management technique can help the efficiency in maintenance and budget management with the limited resource. For its application, there must be a way to evaluate how bridges provide service to users. The level of service can be quantified by a performance measure. This study introduces performance measures and an evaluation process for the determination of level of service. The evaluation results will be used as a fundamental information in the determination of maintenance/repair/management targets and in the decision making process of the bridge asset management.

The new paradigm of urban regeneration, would promote the comprehensive communal view. Therefore, the community role has become an important and necessary for regeneration of communities. It is necessary for urban regeneration which should be matched with the regional characteristics, to develop an evaluation framework that can objectively and accurately diagnose the status of community; so it can be an integrated prescription. A new alternative, asset-based approach may be an alternative to build the community based on opportunities and strengths, which focuses on community inside and things that community have. In this study, a community asset is defined as the tangible and intangible components in the community. A community asset evaluation system is developed through the content analysis related to previous studies of several researchers who investigated the asset-based approaches. Community assets are classified into seven types: human, social, cultural, natural, physical, economic, and political property. Each type is classified into components and establish as a framework with 3 levels in order to set the indicators which can be measured concretely.

Many of the researchers have tried to enhance the satisfaction of both users and owners of social infrastructures by applying the asset management methodology. This study is to develop more efficient asset management framework for bridge management. Based on various literature review, an asset management procedure for bridge management was suggested, and appropriate practices at each step were given. The suggested procedures include the determination of operation and maintenance strategy, level of service, performance measure, valuation of assets, and decision-makings. In addition, this study suggests an applicable decision-making process for the resource distribution based on the management strategy.
