Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

Currently Internet and IT infrastructure of Korea has maintained the world's highest levels. But in another aspect, security incident, especially personal information breaches occur frequently. As personal information leakage happened, the companies will be negatively affected. And to prevent this, they have implemented to use a variety of security solutions from information security vendors. Therefore we set up hypotheses that the companies experienced personal information leakage as well as information security companies providing security solutions will be affected by the leakages. So this paper verify hypotheses about the impact of the value of information security companies, through analysing stock price fluctuation of the companies. We found that the stock price of information security companies has increased as personal information leakage happened. And differences according to leakage volumes and types of business are not statistically significant. But there are significant differences according to business classification of information security companies.

For most organizations, a security infrastructure to protect company's core information and their technology is becoming increasingly important. So various approaches to information security have been made but many security accidents are still taking place. In fact, for many Korean companies, information security is perceived as an expense, not an asset. In order to change this perception, it is very important to recognize the need for information security and to find a rational approach for information security. The purpose of this study is to present a framework for information security strategies of companies. The framework classifies companies into eight types so company can receive help in making decisions for the development of information security strategy depending on the type of company it belongs to. To develope measures to classify the types of companies, 12 information security professionals have done brainstorming, and based on previous studies, among the factors that have been demonstrated to be able to influence the information security of the enterprise, three factors have been selected. Delphi method was applied to 29 security experts in order to determine sub items for each factor, and then final items for evaluation was determined by verifying the content validity and reliability of the components through the SPSS analysis. Then, this study identified characteristics of each type of eight companies from a security perspective by utilizing the developed sub items, and summarized what kind of actual security accidents happened in the past.

In this paper we classify security threat elements of satellite communication into four parts; Level-0(satellite propagation signal), Level-1(satellite control data), Level-2(satellite application data) and ground network security level according to the personality and data of the satellite communication network. And we analyze each security levels. Using analyzed security threat elements, we divide security requirements into signal security level and information security level separately. And then above the existent signal security level countermeasure, we establish the countermeasure on the basis of information security policy such as satellite network security policy, satellite system security policy and satellite data security policy in information security level. In this paper we propose secure satellite communication network through the countermeasure based on information security policy.
