In this paper, we propose an efficient surveillance RADAR(RAdio Detection And Ranging) interface control unit(ICU) design in the naval combat system. The proposed design applied a standardized architecture for modules that can be shared in ship combat system software. An error detection function for each link was implemented to increase the recognition speed of disconnection. Messages that used to be sent periodically for human-computer interaction(HCI) are now only transmitted when there is a change in the datagram. This can reduce the processing load of the console. The proposed design supplements the radar with the waterfall scope and time-limited splash recognition in relation to the hit check and zeroing of the shot when the radar processing ability is low due to the adoption of a low-cost commercial radar in the ship. Therefore, it is easy for the operator to determine whether the shot is hit or not, the probability of wrong recognition can be reduced, and the radar's resources can be obtained more effectively.

The architecture named IDPS is a design concept of web-based integrated platform for heterogeneous naval combat system, which accomplishes efficiency(decreasing complexity) of diagnosis process and reduces time to diagnose system. Each type of surface vessel has its own diagnostic processes and applications, and that means it also requires its own diagnostic engineer(inefficiency in human resource management). In addition, man-based diagnostic causes quality issues such as difference approach of log analysis in accordance with engineer skills. Thus In this paper, we designed integrated diagnostic platform named IDPS with simplified common process regardless of type of surface vessel and we reinforced IDPS with status decision algorithm(SDA) that judges current software status of vessel based on gathered lots of logs. It will enable engineers to diagnose system more efficiently and to use more resources in utilizing SDA-analyzed diagnostic results.

효율적인 인터페이스 정의 및 관리를 위하여 개발된 MDMS (Message Definition and Management System) 는 인터페이스 요구사항명세서(IRS: Interface Requirement Specification)과 인터페이스 설계기술서 (IDD: Interface Design Description), 인터페이스 구현 및 통합의 단계로 이루어진 인터페이스 개발 과정을 통합 관리할 수 있도록 해준다. 이러한 통합관리는 인터페이스 개발에 따른 IRS, IDD, 구현코드에 걸친 일관성 유지를 쉽게 해주며, 소프트웨어 개발 과정에서 가장 문제가 많이 발생하는 단계라고 할 수 있는 소프트웨어 통합에 있어서 인터페이스 불일치로 인한 문제의 대부분을 제거해 준다. MDMS 기반의 인터페이스 관리는 한번의 인터페이스 정의로 IRS, IDD, 송수신 코드까지 생성함으로써 인터페이스 정의 및 개발의 단계를 한단계로 축소하여 각 단계 사이의 불일치 발생이 미연에 방지되며, 일관성 유지 노력이 필요없다. 삼성탈레스에서는 2008 년 이후 10 여개의 함정전투체계 프로젝트의 소프트웨어 개발에 MDMS 를 적용하여 소프트웨어 개발 생산성의 향상을 이루었다. 특히 인터페이스 정의, 설계, 문서 작성, 코드 구현, 형상관리가 통합은 소프트웨어 인터페이스 개발과정에서의 불필요한 중복 작업을 최소화하고, 그에 따른 문서와 코드간의 불일치를 근본적으로 제거할 수 있었다. 또한, 소프트웨어 개발 관리 측면에서도 인터페이스의 복잡도를 평가하여, 향후 유사 시스템의 소프트웨어 아키텍처 구성에 활용할 수 있다.

Recently, various information technologies such as network communication and sensors have begun to be integrated into weapon systems that were previously operated in stand-alone. This helps the operators of the weapon system to make quick and accurate decisions, thereby allowing for effective operation of the weapon system. However, as the involvement of the cyber domain in weapon systems increases, it is expected that the potential for damage from cyber attacks will also increase. To develop a secure weapon system, it is necessary to implement built-in security, which helps considering security from the requirement stage of the software development process. The U.S. Department of Defense is implementing the Risk Management Framework Assessment and Authorization (RMF A&A) process, along with the introduction of the concept of cybersecurity, for the evaluation and acquisition of weapon systems. Similarly, South Korea is also continuously making efforts to implement the Korea Risk Management Framework (K-RMF). However, so far, there are no cases where K-RMF has been applied from the development stage, and most of the data and documents related to the U.S. RMF A&A are not disclosed for confidentiality reasons. In this study, we propose the method for inferring the composition of the K-RMF based on systematic threat analysis method and the publicly released documents and data related to RMF. Furthermore, we demonstrate the effectiveness of our inferring method by applying it to the naval battleship system.
