In this paper, we propose a secure communication framework for interaction and information sharing between a server and agents in DS-NVSA(Detection System of Network Vulnerability Scan Attacks) proposed in〔1〕. For the scalability and interoperability with other detection systems, we design the proposed IDMEF and IAP that have been drafted by IDWG. We adapt IDMEF and IAP to the proposed framework and provide SKTLS(Symmetric Key based Transport Layer Security Protocol) for the network environment that cannot afford to support public-key infrastructure. Our framework provides the reusability of heterogeneous intrusion detection systems and enables the scope of intrusion detection to be extended. Also it can be used as a framework for ESM(Enterprise Security Management) system.

Many companies and departments are increasingly concerned of searching their business information in correct and faster way as they share the information through the internet. LDAP has been proposed for directory server standards which supports storing, searching and managing the business information, and it has become a global standard. Current LDAP, however, cannot solve problem; such as server overloads and data synchronization. This paper describes the history and characteristics of LDAP, and proposes an architecture for solving those problem;. Since the proposed architecture is designed based on the existing LDAP architecture, it guarantees extensibility and portability of server configuration.

B2B registries provide spaces to register and retrieve information which is necessary to support B2B transactions among business partners or potential business partners. Business process specifications are one of important contents in B2B registries, and there is high complexity of representation due to complex and dynamic characteristics of business processes. Also, currently there exist several competing specification frameworks such as ebXML BPSS, WSBPEL, BPMN, and so on. This paper proposes a metadata schema to register business process specifications which are represented by different specification frameworks. The proposed schema has extensibility to register business process specifications which are represented by various different specification frameworks. Also, it extends reuse level from whole business specification processes to their components. To show the usefulness of the proposed schema, this paper demonstrates metadata extraction from business process specifications which are represented by two representative XML-based business process specification languages, ebXML BPSS and WSBPEL.

As it seems like critical information leakages have been increasing due to industrial espionage and malicious internal users, the importance of introducing audit and log security technology is growing every now and then. In this paper, we suggest the session logging system for the company's internal control to meet the SOX legislation level, by monitoring and analyzing users behaviors connecting to the business-critical Operating System. The system proposed in this paper aims to monitor the user's illegal activities in the Operating System, and to present the clear evidence of purpose of those activities by detailed logs. For this purpose, we modified Operating System by adding multiple services suggested in this paper. These services utilize interfaces provided by the existing Operating System and add functions to control access and get logs. The system saves and manages session logs of users or administrators connected to the server with centralized log storage. And the system supports session log searching and lookup features required by SOX legislation for the company's internal controls with the level of computer forensics and logging technology.

In a situation where the use and introduction of Large Language Models (LLMs) is expanding due to recent developments in generative AI technology, it is difficult to find actual application cases or implementation methods for the use of internal company data in existing studies. Accordingly, this study presents a method of implementing generative AI services using the LLM application architecture using the most widely used LangChain framework. To this end, we reviewed various ways to overcome the problem of lack of information, focusing on the use of LLM, and presented specific solutions. To this end, we analyze methods of fine-tuning or direct use of document information and look in detail at the main steps of information storage and retrieval methods using the retrieval augmented generation (RAG) model to solve these problems. In particular, similar context recommendation and Question-Answering (QA) systems were utilized as a method to store and search information in a vector store using the RAG model. In addition, the specific operation method, major implementation steps and cases, including implementation source and user interface were presented to enhance understanding of generative AI technology. This has meaning and value in enabling LLM to be actively utilized in implementing services within companies.
