소프트웨어 정의 네트워크(SDN)의 등장은 학계와 산업계에 큰 영향을 주었다. SDN은 물리적인 장치를 변경하지 않고 네트워크 관리자의 의도대로 대상 네트워크를 관리 할 수 있기 때문에, 능동적이고 유연한 관리환경을 제공한다. 보안측면에서 SDN 기반의 네트워크는 다양한 공격을 탐지하는 데 유용하게 쓰인다. 하지만 대부분의 SDN을 이용한 보안 연구는 네트워크에만 집중되어 있고, 호스트를 고려하지 않고 있다. 이와 더불어 SDN 기반의 보안 애플리케이션을 제작하기 위해서는, SDN을 운용하는 컨트롤러와 다양한 지식이 요구된다. 본 연구에서는 SDN 기반의 호스트와 네트워크를 모두 고려하는 보안 애플리케이션 제작의 어려움을 해결하기 위해, 소프트웨어 정의 네트워크 기반 위협 대응 프레임워크를 제안한다.

The hospital biomedical engineering team is responsible for establishing and regulating the Medical Device Management Program (MEMP) to ensure that medical devices are safe and reliable. As technology advances, medical devices such as artificial intelligence and precision medicine are developing into a form that allows connection between objects anytime, anywhere, and as various technologies converge, internal and external security threats continue to increase. In this paper, we present a study of the Medical Device Management Program (Secure-MEMP) method, considering that the security threat of medical devices continues to increase due to advances in technology.

This paper examines the security threats to enterprise Generative Artificial Intelligence systems and proposes countermeasures. As AI systems handle vast amounts of data to gain a competitive edge, security threats targeting AI systems are rapidly increasing. Since AI security threats have distinct characteristics compared to traditional human-oriented cybersecurity threats, establishing an AI-specific response system is urgent. This study analyzes the importance of AI system security, identifies key threat factors, and suggests technical and managerial countermeasures. Firstly, it proposes strengthening the security of IT infrastructure where AI systems operate and enhancing AI model robustness by utilizing defensive techniques such as adversarial learning and model quantization. Additionally, it presents an AI security system design that detects anomalies in AI query-response processes to identify insider threats. Furthermore, it emphasizes the establishment of change control and audit frameworks to prevent AI model leakage by adopting the cyber kill chain concept. As AI technology evolves rapidly, by focusing on AI model and data security, insider threat detection, and professional workforce development, companies can improve their digital competitiveness through secure and reliable AI utilization.

According to IT development, smart home services is providing remote service, monitoring service and other various services through smart home devices based on network. But, smart home environment exists security threats such as data falsification, illegal authentication and invasion of privacy through a malicious device. Smart home is studying to prevent these security threats, but the studies of smart home environment security are still in early stage of development and the studies of group key management method is lacking in smart home. In this paper, we propose the group key management method for secure device in smart home.

By increasing of the population that uses smartphones, problems such as the leakage of private and confidential information due to portable and easy to store and movement of diverse contents occur for a variety of security threats. In this report, it provides helpful information to customers in order to respond various security threat by implementing and designing an remote administration system with using Mobile Device Management (MDM), technology. As a result, customers themselves can prevent information spill by managing remotely from WEB due to the lost and stolen. It is also possible to use control and monitoring.
