As of July 1. 2001, the Law of Information 8t Telecommunication Protection has been compulsory to audit protection status on national information and Telecommunications Infra facilities such as communication, electricity, waterworks, airport, railway, primary facilities of government and the first financial circles. In U.S. institutions, organizations and corporations in each field are trying to prepare for Safe Har-bor agreed on Internet privacy regulation between U.S. and Europe to be effective in 2003. The Safe Harbor was motl-vated by strict European standard. Other countries make privacy and information protection law according to their own interest. Therefore Korean technical experts have to develop the law responding to national interest and public welfare. Besides scientific Held, experts in the field of politic, economy and academy also have to work hard to develop the law.

최근 여기어때, 인터파크 등 전자상거래 기업을 대상으로 발생한 개인정보 해킹사고 사례를 보면, 사람의 취약점을 노리는 지능화지속위협(APT) 공격과 알려진 해킹 기술이 복합적으로 이루어지고 있다. 해킹사고가 발생한 기관은 한국인터넷진흥원(KISA) 정보보호관리체계(ISMS) 의무대상 기관으로써 정보보호관리체계를 유지 관리하고 있었다. 그럼에도 불구하고 대형의 개인정보 유출사고가 발생한 주요 원인은 정보보호관리체계가 적용되지 않았던 정보시스템과 인력을 대상으로 해킹이 이루어졌기 때문이다. 해킹 위협의 변화에 따라 전자상거래 보안 수준도 변화해야 하는데, 개인정보보호 관련 규제 준수도 전자상거래 기업에서는 힘든 상황이다. 고객의 개인정보 유출 사고는 일반인을 매출 기반으로 서비스하고 있는 전자상거래 기업에서는 치명적이다. 안전한 전자상거래 플랫폼 기반에서 고객에게 서비스를 제공하기 위해서는 무엇보다도 중요 자산인 고객의 개인정보보호를 위해 역량을 집중해야 한다. 한정된 예산과 자원으로 안전한 서비스를 제공하기 위해서는 기존에 구축된 정보보호관리체계를 기반으로 IT보안감사체계를 전사적으로 확대하여 지속적으로 모니터링 할 필요가 있다. 이에 본 연구에서는 최신 사이버 보안 위협 동향과 전자상거래 기업 대상으로 발생한 최근 개인정보유출사고 사례를 분석을 통해 시사점을 도출하여 전자상거래 개인정보 보호를 위한 IT보안감사체계를 제시하였다.

Data security is the planning, implementation and implementation of security policies and procedures for the proper audit and authorization of access to and use of data and information assets. In addition, data serviced through internal / external networks, servers, applications, etc. are the core objects of information protection and can be said to focus on the protection of data stored in DB and DB in the category of information security of database and data. This study is a preliminary study to design a proper Data Security Management System (DSMS) model based on the data security certification system and the US Federal Security Management Act (FISMA). And we study the major security certification systems such as ISO27001 and NIST's Cybersecurity Framework, and also study the state of implementation in the data security manager solution that is currently implemented as a security platform for preventing personal data leakage and strengthening corporate security.

Critical information infrastructure designations for cloud service providers continue to spread around the world as energy, financial services, health, telecommunications, and transportation sectors move to the cloud. In addition, in the case of Ukraine, the removal of restrictions on the use of cloud for national critical facilities and the rapid transition of critical data to the cloud enabled the country to effectively respond to cyberattacks targeting Russian infrastructure. In Korea, the ISMS-P is operated to implement a systematic and comprehensive information protection management system and to improve the level of information protection and personal information protection management in organizations. Control items considering the cloud environment have been modified and added to the audit of companies. However, due to the different technical levels of clouds between domestic and global, it is not easy to obtain information on the findings of cloud providers such as Microsoft for the training of domestic certification auditors on hyperscale scale. Therefore, this paper analyzes findings in hyperscale clouds and suggests ways to improve cloud-specific control items by considering the compatibility of hyperscale environments with ISO/IEC 27001 and SOC(System and Organization Control) security international standards.

The main objective of this study was to identify the factors that can maximize the effect of preventing technology leakage by government support. Therefore we used the 2013 small business technology protection capabilities and level of research which is conducted by the Small and Medium Business Administration, and have analyzed the presence of small business technological assets leakage protection eand skills. Multiple logistic regression analysis was performed to identify 1,518 small companies (43 big companies are excluded) which are divided into 155 technological assets leaked small business and non-leaked 1363 small business. The most important factors associated with technology leakage were entrant control system, security audit, employee absence of security activities and important data protection measures. This result shows that if the government can support more for these details, technological asset leakage prevention effect is expected to be maximized.

Globally researchers at medical institutions are actively sharing COHORT data of patients to develop vaccines and treatments to overcome the COVID-19 crisis. OMOP-CDM, a common data model that efficiently shares medical data research independently operated by individual medical institutions has patient personal information (e.g. PII, PHI). Although PII and PHI are managed and shared indistinguishably through de-identification or anonymization in medical institutions they could not be guaranteed at 100% by complete de-identification and anonymization. For this reason the security of the OMOP-CDM database is important but there is no detailed and specific OMOP-CDM security inspection tool so risk mitigation measures are being taken with a general security inspection tool. This study intends to study and present a model for implementing a tool to check the security vulnerability of OMOP-CDM by analyzing the security guidelines for the US database and security controls of the personal information protection of the NIST. Additionally it intends to verify the implementation feasibility by real field demonstration in an actual 3 hospitals environment. As a result of checking the security status of the test server and the CDM database of the three hospitals in operation, most of the database audit and encryption functions were found to be insufficient. Based on these inspection results it was applied to the optimization study of the complex and time-consuming CDM CSF developed in the "Development of Security Framework Required for CDM-based Distributed Research" task of the Korea Health Industry Promotion Agency. According to several recent newspaper articles, Ramsomware attacks on financially large hospitals are intensifying. Organizations that are currently operating or will operate CDM databases need to install database audits(proofing) and encryption (data protection) that are not provided by the OMOP-CDM database template to prevent attackers from compromising.
