최근 IT 제품의 활용의 증가와 함께 소프트웨어는 컴퓨터를 넘어 적용 범위가 더욱 넓어지고 그에 따른 수요 또한 급격히 성장하고 있다. 또한 상용 소프트웨어와 더불어 오픈소스 소프트웨어(Open Source Software)의 수요도 함께 급성장하고 있다. 하지만 오픈소스 소프트웨어는 보안에 대한 전문지식이 없는 개발자에 의해 개발이 이루어진다. 이에 하트블리드(HeartBleed), 쉘쇼크(ShellShock)와 같은 다양한 보안취약점(Security Vulnerabilities)이 발생하고 있으며 공격으로 이어지는 사례도 늘고 있다. 따라서 본 논문에서는 다른 소프트웨어 점검 도구들과 연계하여 발견된 보안취약점이 익스플로잇터블(Exploitable)한 지 검증하는 엔진을 제안한다.

In this paper, we developed an e-loaming contents for C programming language using Linux and open source software, not using commercial integrated development tool like Microsoft's Visual Studio. In most programming language courses, students study or practice the programming language by editing source code compiling and running the executable code by commercial software like Visual Studio which installed on each PC. This way of learning has some difficulties in total cost of purchasing software and using other PCs which donot have proper software installed. To overcome this situation and enable loaming anywhere, with any device, at anytime, we propose a way of utilizing Linux and open source software in Web-based learning environment. In this environment students can input their source code on the form of broweser and get the result instantly from the server.

The spectral radiance received by an infrared (IR) sensor is mainly influenced by the surface temperature of the target itself. Therefore, the precise temperature prediction is important for generating an IR target image. In this paper, we implement the combined three-dimensional surface temperature prediction module against target attitudes, environments and properties of a material for generating a realistic IR signal. In order to verify the calculated surface temperature, we are using the well-known IR signature analysis software, OKTAL-SE and compare the result with that. In addition, IR signal modeling is performed using the result of the surface temperature through coupling with OKTAL-SE.

To use commercial software, most software users purchase the software. Some software users, who do not use the software frequently, regard purchasing the software as undue expense. Software rental service can be an effective substitute. To support the software rental service, charging scheme is necessary. Two categories of charging scheme can be considered. One is charging a fixed amount of fee for a fixed period of time and the other is charging a fee based on the actual usage time. In this paper, the software pay-per-use approach based on the amount of time that the software user has used is proposed. The proposed approach gives the capability to calculate the usage time.

For data such as rainfall and soil moisture, it is important to obtain the values of all points required as geostatistical data. Spatial interpolation is generally performed in this process, and commercial software such as ArcGIS is often used. However, commercial software has fatal drawbacks due to its high expertise and cost. In this study, R, an open source-based environment with ArcGIS, a commercial software, was used to compare the differences according to the processing environment when performing spatial interpolation. The data for spatial interpolation was weather forecast data calculated through Land-Atmosphere Modeling Package (LAMP)-WRF model, and soil moisture data calculated for each cumulative rainfall scenario. There was no difference in the output value in the two environments, but there was a difference in user interface and calculation time. The results of spatial interpolation work in the test bed showed that the average time required for R was 5 hours and 1 minute, and for ArcGIS, the average time required was 4 hours and 40 minutes, respectively, showing a difference of 7.5%. The results of this study are meaningful in that researchers can derive the same results in a commercial software environment and an open source-based environment, and can choose according to the researcher's environment and level.

The 'Open Source' of programing is a method that is not only sharing the source, but also making the S/W by the low cost and easy way. In this study, we made the urban facilities management system(FMS) based on the GeoFOSS of Open Source. This system has the GIS function of the urban facilities management, the u-GIS function using the USN for processing the spatial information. Also, as we use the GeoFOSS of 'Open Source', we can have received many benefits. First, this system has the economic impact, because it is not necessary to buy the commercial GIS software. Second, this system can make most functions of the GIS, the performance does not bad compared to other products. Also, this system strictly conforms to the international standards, it is easy to get a repair, maintenance and interoperability.

This study presents a model and its implementation methodology assessing not only maturity but also applicability in order to increase the practical usage of open source software(OSS). Since this model measures applicability which can not be assessed by the previous models, it is able to support users in many ways when they introduce OSS for the first time, replace commercial software with OSS, and compare OSS with commercial software. For the purpose of design and implementation of this model, we presented a methodology with 7 phases and conducted a survey to evaluate the appropriateness and reliability of the model. In addition, we proved the practical usability of the model by providing a practical example assessing maturity and applicability of OSS in the area of the infra category on the basis of the methodology. In the future, not only general users but also officers in charge of informatization will be able to select optimal OSS by using this model for industrial application. Therefore, the result of this research is expected to greatly contribute to OSS promotion policy.
