Information security companies were established in earnest from the mid-late 1990s to early 2000s, far shorter than other national key industries. Nevertheless, the information security industry has made rapid progress. It is expected that the proportion of the information security industry will increase rapidly with the development of advanced technology along with the 4th industrial revolution. As COVID-19, which occurred at the end of 2019, spreads around the world in 2020, non-face-to-face services and digital transformation are accelerating, and cyber threats to users are also increasing. However, there are limitations in responding to new Cyber Security threats due to the shortage of information protection manpower, insufficient security capabilities of domestic companies, and the narrow domestic information protection market. This study examines the external environmental factors of information security companies such as government information protection system operation, government influence, government support, partnership between information security companies, and internal environmental factors such as top management support, financial status, human resources, organizational capability, This study was conducted using empirical data to analyze whether it affects innovation capability and whether organizational capability and innovation capability affect financial and non-financial performance. The results of this study can be used as basic data to suggest policies and implications for information security, and to strengthen the competitiveness of the information security industry.

The Robot Operating System (ROS) has become a critical platform for developing advanced robotic systems across various fields, including smart homes, autonomous driving, and industrial automation. By modularizing complex robotic systems, ROS enables nodes to cooperate effectively while adopting a structure where each node operates as an independent process, ensuring fault isolation. However, the use of inter-process communication (IPC) introduces performance degradation and resource inefficiencies, particularly in scenarios involving frequent message exchanges or large-scale data processing. To address these challenges, ROS2 introduced the Composition feature, allowing multiple nodes to execute within a single process. While this approach improves communication efficiency by leveraging shared memory, it also raises potential security risks due to the shared address space. Specifically, loose memory access controls between nodes increase the likelihood of security vulnerabilities, which existing mechanisms such as Secure ROS (SROS) struggle to mitigate effectively. This paper proposes a novel method to enhance security and improve memory management in ROS Composition environments. By independently managing the memory segments of each node, the proposed mechanism prevents data interference and ensures secure memory access. Experimental results demonstrate that the method maintains stable performance with a low overhead of 3% to 10%, effectively enhancing the security of ROS Composition environments.

Widespread use of Internet despite numerous positive aspects resulted in increased number of system intrusions and the need for enhanced security mechanisms is urgent. Systematic collection and analysis of log data are essential in intrusion investigation. Unfortunately existing logs are stored in diverse and incompatible format thus making an automated intrusion investigation practically impossible. We examined the types of log data essential in intrusion investigation and implemented a tool to enable systematic collection and efficient analysis of voluminous log data. Our tool based on RBDMS and SQL provides graphical and user-friendly interface. We describe our experience of using the tool in actual intrusion investigation and explain how our tool can be further enhanced.

There are several big data-driven advanced research activities such as meteorological climate information, high energy physics, astronomy research, satellite information data, and genomic research data on KREONET. Since the performance degradation occurs in the environment with the existing network security equipment, methods for preventing the performance degradation on the high-performance research-only network and for high-speed research collaboration are being studied. In addition, the recent issue of quantum computers has been a threat to security using the existing encryption system. In this paper, we construct quantum cryptography-based communication network through environment construction and high-performance transmission test that build physical security through quantum cryptography-based communication network in end-to-end high-speed research network. The purpose of this study is to analyze the effect on network performance when performing physical encryption and to use it as basic data for constructing high-performance research collaboration network.

In recent years, the ROK military is promoting Defense Innovation 4.0 with the goal of fostering strong military based on science and technology equipped with artificial intelligence(AI) to prepare for the upcoming population cliff. In particular, at the present time of increased threats of North Korea, the South Korean military is seeking to deal with a decrease in military service resources through the introduction of a Scientific Guard System using advanced technology. TICN which is a core basic communication system to ensure the integrated combat capability of the ROK military is, however, limited to use as a based network for the emerging Scientific Guard System due to the narrow transmission bandwidth with widely spread poor reception area. To deal with this problem, this paper proposes TVWS-based Scientific Guard Systems with TVWS-based wireless network construction technology that has been available for free in Korea since 2017. The TVWS-based Scientific Guard System proposed in this paper, when compared to the existing wired network-based Scientific Guard Systems, has various advantages in terms of minimizing operational gaps, reducing construction costs, and flexibility in installation and operation.

Future warfare is expected to be multi-domain operations including space, based on the development of advanced information and communication technologies. Advanced space-faring countries such as the United States, Russia, China, and Japan are creating space forces based on advanced space technology to prepare for future space warfare and strengthening cooperation with private companies and other countries. The South Korean military is preparing for space warfare for each type of weapon, but it is still relatively weak in terms of integrated strategy and technology. As not only advanced space countries but also North Korea is increasing its investment in space militarisation, the ROK military needs to develop a comprehensive plan and establish a specialized organisation to prepare for future space warfare. Therefore, this paper examines the current status of the ROK military's space warfare preparedness and proposes space warfare strategies such as establishing a dedicated space warfare and space cybersecurity organization, strengthening domestic and international cooperation, research and development and training of specialized personnel, and reestablishing a training system.
