The main purpose of the study is to analyze the features of ensuring the financial and economic security of the state in an aggressive external environment. The concept of financial and economic security should contain the priority goals and objectives of ensuring security, ways and methods to achieve them, adequately reflecting the role of finance in the socioeconomic development of the state. Its content is designed to coordinate nationwide actions in the field of security at the level of individual citizens, business entities, industries, sectors of the economy, as well as at the regional, national and international levels. The methodology includes a number of scientific and theoretical methods of analysis. Based on the results of the study, the key aspects of the system for ensuring the financial and economic security of the state in an aggressive external environment were identified.

The most important issue in database security is correct concurrency control under the restrictive security policy. The goal of secure transaction management is to keep security and provide many concurrent users with the high availability of database. In this paper, we consider the security environment of multidatabase system with replicated data. The read-from relationship in the existed serializability is improper in security environment. So, we define new read-from relationship and propose new secure 1-copy quasi-seriailzability by utilizing this relationship and display some examples. This security environment requires both the existed local autonomy and the security autonomy as newly defined restriction. To solve covert channel problem is the most difficult issue in developing secure scheduling scheme. The proposed secure 1-copy quasi-serializability is very proper for global transactions in that this serializability not violates security autonomy and prevents covert channel between global transactions.

According to arriving convergence environment which can create new value-added converged between industry and ICT technology, It has made economic growth and improve the quality of life. However this convergence environment provide not only advantage but also various security problems resulting from generating converged security threats. For resolving this security problem, we need to approach to security problem in the integrated view not the fragmentary view which cover only technical approach. So This study developed security governance framework which can manage trustful security governance in multidimensional view which cover strategy, managerial/operational and technical view. Therefore this framework can construct trustful security management system which can help top management team to engage in security management directly and organizational member to perform security activities and have responsibility for themselves as suggesting single standard for security management.

In this paper, we designed the security management system based on IEC 62351-7 in the Smart Grid environment. The scope of IEC 62351-7 focuses on network and system management (NSM) of the information infrastructure as well as end-to-end security through abstract NSM data objects for the power system operational environment. However, it does not exist that security management system based on IEC 62351-7 manages the security of the power system in the Smart Grid environment, because power equipment or SNMP agents providing NSM data do not exist yet. Therefore, we implemented the security management system to manage the information infrastructure as reliably as the power system infrastructure is managed. We expect that this system can perform the security management of IEC 61850 based digital substation and can be a prototype of the security system for the Smart Grid in the future.

Trusted operating systems (OS) provide the basic security mechanisms and services that allow a computer system to protect, distinguish, and separate classified data. Trusted operating systems have been developed since the early 1980s and began to receive National Security Agency (NSA) evaluation in 1984. The researches about trusted OS are proceeding over the world, and new product type using the loadable security kernel module (LSKM) or dynamic link library (DLL) is being developed. This paper proposes a special type of product using LSKM and specific conditions for operational environment should be assumed.

The emerging field of Science of Security (SoS) is a new paradigm that emerged in the field of security as a research field that applied the scientific approach to cyber security. It is a direction to study the formal model and automation field to secure the security of such a network environment in the present that dynamic change of complex, large scale network environment and a lot of protocol and mechanism environment exists. Therefore, this study analyzes the latest cyber security research trends such as SoS and examines the research trends of advanced countries to examine a new approach to cyber security development direction in Korea. We also analyze the current state of domestic scientific research on the scientific security research methods for various cyber security paradigms and present directions for revitalizing domestic cyber security.

The IoT environment is very vulnerable to security threats, and if an intrusion occurs, it can cause great damage. In order to strengthen the security of the IoT environment, a curriculum that considers the characteristics of the IoT environment is needed. In this paper, we propose a curriculum model for cyber incident response in the Internet of Things environment. The proposed curriculum model was designed as a model for security threats in the IoT environment, types of intrusion incidents, and incident response procedures. The proposed curriculum model is expected to contribute to improving security awareness in the IoT environment and fostering cyber incident response experts in the IoT field. The proposed curriculum model strengthens the security of the IoT environment and is expected to be safe through security incident response in the IoT.

Recently, Interest variety of IT services and computing resources are increasing. As a result, the interest in the security of cloud environments is also increasing. Cloud environment is stored that to provide services to a large amount of IT resources on the Cloud. Therefore, Cloud is integrity of the stored data and resources that such as data leakage, forgery, etc. security incidents that the ability to quickly process is required. However, the existing developed various solutions or studies without considering their cloud environment for development and research to graft in a cloud environment because it has been difficult. Therefore, we proposed wire-wireless integrated Security management Model in cloud environment.

This research suggests the security countermeasures for solving technology outflow of small-medium companies in New IT Environment through level comparison of security cognition and security management between small-medium companies and major big companies. According to analysis results, it is poor for small-medium companies' level of security cognition and security management compared with major big companies. Small-medium companies need to manage technology outflow to major big companies' level in New IT Environment. Small-medium companies has started to build New IT Environment recently and it must build the appropriate security system for small-medium companies at the same time. Small-medium company has more problem with budget and proffessionals to maintain the security of technology outflow. Therefore government has to support systematic management for the security of technology outflow to Small-medium companies
