Providing trading partners with personal information to establish an e-commerce financial transaction is inevitable. Most e-commerce companies keep personal information and transaction data for user's convenience and develop additional services as their applications. However, keeping personal information increases the likelihood of identity theft causing direct or indirect damage while it may simplify repetitive financial transactions. This study introduces risk management methods based on quantitative and qualitative analysis including demand-supply curve model and Gordon & Loeb model to analyze the risks for security management. The empirical analysis with survey results from KISA (Korea Information Security Agency) shows that the root cause of different statistics of personal information leakage incidents according to core business of internet companies is the difference in their Loss Expectancy caused by them. Also we suggest disciplinary compensation and higher standard for personal information protection as a solution to prevent the variation of investment on it between individual companies.

As military service members are fully permitted to use mobile phones for sickness after work, it is time to minimize the direct collection of personal information from telecommunication companies when opening mobile phones to secure the safety of military service personnel's personal information. Prior to introducing the use of mobile phones by soldiers after work, the Ministry of National Defense established a security control system such as blocking the mobile phone shooting function to prevent security accidents and concerns about some adverse functions such as illegal cyber gambling, game addiction, and viewing pornography. come. Mobile telecommunications companies entrust personal information processing tasks, such as opening mobile phones, to telecommunications agencies and carry out management and supervision, such as checking the status of personal information protection measures. When a military service member opens a mobile phone, a personal information management agency is newly established using the right to portability of personal information, and a system for requesting the transmission of personal information from the military service member is proposed.

For social demand and technological development, systematic private information management and security guidance have been enhanced; however, the issue of leakage and invasion of private information is shown in many ways. In the management of such private information, the issue of how to protect such information is one of the sensitive key elements. As a criterion to decide the management policy of each property information consisting of private information, this article suggests Dynamic-Security-Level-Measurement for property information. DSLM adopts the variable characteristics of property information as the element of measurement. By applying this method, it is possible to provide information management functions to cope with the changes of each property information security level of an individual actively. It is expected that this will improve the security of previous information management methods even more and also contribute to the improvement of security in integrated systems such as the integrated ID management system and electronic wallet.

Big Data is strictly positioning one of method to deal with problems faced with mankind, not an icon of revolution in future anymore. Application of Big Data and protection of personal information have contradictoriness. When we weight more to usage of Big Data, someone's privacy is necessarily invaded. otherwise, we care more about keeping safe of individual information, only low-level of research using Big Data can be used to accomplish public purpose. In this study, we propose a method to anonymize Big Data collected in order to investigate the problems of personal information infringement and utilize Big Data and protect personal. This will solve the problem of personal information infringement as well as utilizing Big Data.

Recently, organizational efforts to adopt ISMS(Information Security Management System) have been increasingly mandated and demanded due to the rising threat and the heavier cost of security failure. However there is a serious gap between awareness and investment of information security in a company, hence it is very important for the company to control effectively a variety of information security threats within a tight budget. To phase the ISMS, this study suggests the priorities based on evaluating the Importance of 13 areas for the ISMS by the information security experts and then we attempt to see the difference between importance and investment through the assessment of the actual investment in each area. The research findings show that intrusion incident handling is most important and IT disaster recovery is the area that is invested the most. Then, information security areas with the considerable difference between priorities of importance and investment are cryptography control, information security policies, education and training on information security and personnel security. The study results are expected to be used in making a decision for the effective investment of information security when companies with a limited budget are considering to introduce ISMS or operating it.

정부에서는 내·외부 사이버 보안 위협 고도화에 대한 실질적이고 효과적인 대응을 위해 정보보호관리체계(Information Security Management; 이하 ISMS) 인증에 대한 법령을 시행하고 있다. ISMS 인증은 컨설팅과 인증심사를 분리하여 독립성을 확보하였으며, 현장심사 비중을 높여 기존 문서심사에 치중되었던 인증·평가제도와의 차별화를 통해 실효성을 증진시켰다. 그러나 최근 ISMS 인증을 받은 대상자임에도 불구하고 개인정보 정보유출 사고, 대규모 서비스 장애가 유발됨으로써, 다시금 ISMS 인증의 실효성 문제가 제기되고 있다. 현재 제기되고 있는 문제의 요인은 인증기준에 적합한 최소한의 요구사항만 심사·심의하는 ISMS 인증의 한계점에 기인한다. 본 논문에서는 이와 같은 ISMS 인증의 실효적 한계점을 개선하고 인증취득 대상자의 실질적 보안역량 강화시키기 위하여 성숙도 평가모델에 기반한 ISMS 인증제도 운영 방안을 제언한다.

This study focused on the role of the center for private information, which can manage and share the personal data from data breach incidents. Especially, this study addresses on the importance of establishing information management systems for preventing secondary misappropriation of breached personal data and private information. The database of breached personal data can be used for reducing privacy worries of potential victims of secondary misuse of personal data. Individuals who use the same IDs and passwords on multiple websites may find this service more effective and necessary. The effectiveness of this breached data center on reducing secondary privacy infringement may differ depending on the extend of data being shared and the conditions of data submission. When businesses experienced data breach and submission of data to this center is required by the law, the accuracy and effectiveness of this service can be enhanced. In addition, centralized database with high quality data set can increase matching for private information and control the secondary misappropriation of personal data or private information better.
