향후 사이버전 환경에서는 기존의 인터넷망과 인터넷 서비스에 대한 사이버 공격을 통한 서비스의 마비 뿐만 아니라, 무기체계 자체에 대한 사이버 공격을 통해 군사 지휘통제에 대한 전략적 수단과 군사작전 수행의 마비를 위한 전술적 수단으로써의 다양한 사이버 공격형태들이 발생할 것이 예상된다. 이러한 사이버 공격에 대한 대응 수단으로 무기체계 내장형 소프트웨어에 대한 시큐어 코딩의 적용이 필요하며, 본 논문에서는 무기체계 내장형 소프트웨어에 대한 시큐어 코딩 적용 관련한 그 동안의 연구 동향을 살펴보고 향후 연구 방향을 제안하였다.

Korean military uses 'Tactical information communication network' to exchange information between units. In this study, we developed a media processing board for multi-party voice and video telephony based on open source software. On the other hand, in order to apply open source software for weapon systems and parts that are mounted on weapon systems, appropriate review is required according to the weapon system software development and management manual of the Defense Acquisition Program Administration (DAPA). In this study, the analysis of the requirement items was performed and the appropriate countermeasures were proposed for the open software applied to the media processing board with respect to 'the guidelines for the application of weapon systems to open source software', an appendix to the DAPA's manual.

In this paper, we propose the enhanced Assessment Model of the Embedded Software Process(MND-ESPAM) which is suitable for the development work of weapons in Korea. In 2008. We developed the MND-ESPAM which is the assessment criteria of software process, but this model is inefficient to apply to Korean military area. Therefore, we elicit and analyze the problems of MND-ESPAM through tow methods. One is to research on the actual condition of the domestic defense industry about software process management. And the other is to apply MND-ESPAM to the defense companies acquiring CMMI level. In order to overcome these problems elicited above, we provide solutions to make MND-ESPAM linked with Software Development Process Guide of Defense Acquisition Program Administration(DAPA) and to systematically strengthen testing activities and to reduce the number of process areas. The proposed model was proved by two objective methods such as checking the coverage with CMMI and whether it is satisfied or not by modified requirements ISO/IEC 14598-3. At last, experts in the field of software process confirmed the effect of MND-ESPAM through applying MND-ESPAM to the defense industry company.

Recently, the Ministry of National Defense has included embedded software for weapon systems as targets for the Defense cyber security. The Concept has been extended and evolved from the cyber security area that was previously limited to the information domain. The software is becoming increasingly important in weapon systems, and it is clear that they are subject to cyber threats. Therefore, We would like to suggest a improvement direction by diagnosing problems in terms of cyber security of the weapon systems for the life cycle. In order to improve cyber security of weapon systems, comprehensive policy including the weapon embedded software management should be established and the involved stakeholder should be participated in the activities.

In the case of weapon systems used by the military, defense standards are applied for economical and efficient procurement, management, and maintenance. Defense specifications are documents describing procedures and methods for determining whether technical requirements for products and services are consistent and apply to the production of weapon systems, quality assurance, and configuration management. Software is also subject to defense specifications, and is documented and managed in the same way as other defense specifications. Sometimes it happened to be standardized without some(or all) software. In this case, a competitive contract is impossible and it may affect the quality of weapon systems because the manufacturer arbitrarily changes the software without prior approval. So, software standardization is required, but it is very difficult to verify for firmware installed in hardware. This paper proposed a verification method for g software standardization, and we expect it will contribute to the efficient production and quality assurance of weapon systems.

In the domain of Korean weapon system development, issues about software reliability have become crucial factors when developing a weapon system. There is a process required for weapon system software development and management that includes certain activities required to improve the reliability of software. However, these activities are biased toward static and dynamic analyses of source code and do not include activities necessarily required by the international standard. IEEE std. 1633-2016 defines a process for software reliability engineering and describes software reliability estimation as an essential activity in the process. Software reliability estimation means that collecting defective data during the test and estimating software reliability by using the statistical model. Based on the estimated model, developers could estimate the failure rate and make comparisons with the objective failure rate to determine termination of the test. In this study, we collected defective data and applied reliability estimation models to analyze software reliability in the development of a weapon system. To achieve objective software reliability, we continuously tested our software and quantitatively calculated software reliability. Through the research, we hope that efforts to include activities described by the international standard will be carried out in the domain of Korean weapon system development.

In this paper we design the system test model for the weapon system embedded software based on the Time Factor Method(TFM) considering time factors and suggest the results through the case study. For doing this, we discuss the features, system tests and the object-oriented model based UML notations of the weapon system embedded software. And we give a test method considering time factors, a measuring method to time factors, and a test case selection algorithm as an approach to the TFM for designing the system test model. The TFM based system test model consists of three factors (X, Y, Z) in the weapon system embedded software. With this model, we can extract test cases through the selection algorithm for a maximum time path in 'X', identify the objects related to the Sequence Diagram in 'Y' and measure the execution time of each objects which is identified by the Timing Diagram in 'Z' Also, we present the method of extracting the system test cases by applying the proposed system test model to the 'Multi-function missile defense system'.

Modeling and Simulation techniques are useful to construct executable battlefields and forces on computers, and have been utilized to analyze effectiveness of weapon systems in the computerized war environment. However, most weapon simulations so far have exhibited low reusability and extensibility, since they have been developed for specific simulation objectives with different structures and simulation engines. In this paper, we identify requirements for defense modeling and simulation activities and propose a simulation engine to support the identified requirements. We define the software architecture of the proposed engine, in a way to efficiently provide usability, component-based reusability, interoperability, and reuse-based development.

This study evaluated the process of software quality assurance about the initial product in a weapon system. The software quality assurance of the initial product was insufficient before this study. Therefore, the process of the software quality assurance about the initial product in a weapon system is suggested. The process has three parts. First, the completeness of computer files, such as source code and execute files, were checked. Second, the suitability of the software technical data was checked. Finally, the connectivity of software technical data and the Korean defense specification were assessed. Overall, there is a need to toughen the software quality assurance in the research and development step and achieve early stabilization of mass production by preventing the problems that prevent the production of a product due to the insufficient software technical data.

무기체계에 내장되는 소프트웨어는 국방 자산으로 효율적인 관리가 되지 않는 상태라고 볼 수 있다. 체계적인 소프트웨어 개발관리를 요구하는 명문화된 정부의 규정이 미비한 점과 소프트웨어 개발에 투입된 비용을 적정하게 보전해 주지 못하는 원가계산 방식 등이 국내 방산부분의 소프트웨어 산업 활성화를 저해하는 1차적인 요인으로 지적할 수 있고, 더불어서 표준화된 소프트웨어 개발 프로세스를 구축하여 시행하려는 업체의 기술적인 노력이 부족했었던 점도 방산부분의 소프트웨어 산업이 활성화되지 못한 주요 원인에 포함된다고 할 수 있다.
