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.

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.

Recently, as personal information has been used as data, various new industries have been discovered, but cases of personal information leakage and misuse have occurred one after another due to insufficient systematic management system establishment. In addition, services that use personal information anonymously and anonymously have emerged since the enforcement of the Data 3 Act in August 2020, but personal information issues have arisen due to insufficient alias processing, safety measures for alias information processing, and insufficient hate expression. Therefore, this study proposed a new PbD principle that can be applied to the pseudonym information life cycle based on the Privacy by Design (PbD) principle proposed by Ann Cavoukian [1] of Canada to safely utilize personal information. In addition, the significance of the proposed method was confirmed through a survey of 30 experts related to personal information protection.

The information security management system (ISMS) and the personal information management system (PIMS) have been integrated into a personal information & information security management system (ISMS-P) certification scheme in response to requests to reduce the time and cost to prepare certification schemes. Integration of the certification system has made it possible for the system operator to gain the advantage of easy management of the ISMS-P certification system, and the certification target organization can enjoy the advantage of easy acquisition and maintenance of certification. However, ambiguity in the application criteria of the target organization, and ambiguity in the certification criteria control items require the target organization to operate an excessive management system, and the legal basis to be applied to the certification target organization is ambiguous. In order to improve these problems, this paper uses case studies to identify the types of certification bodies that apply the certification criteria, and to change the control items applied during certification audits based on the types of certification bodies. Institutions that wish to obtain only ISMS certification have proposed three solutions, excluding controls covered by the ISMS-P. This paper suggests ways to operate an efficient certification system, and can be used as a basis for improving problems in the ISMS-P certification system.

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.

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.

Many domestic organizations are introducing and operating various information security management systems capable of coping with technical, administrative, and legal issues comprehensively and systematically, in order to prevent various infringement incidents such as personal information disclosure and hacking preemptively and actively. However, empirical analyses regarding the extent to which an information security management system contributes to information security performance have not been fully conducted, even though enterprises and organizations are actively introducing such systems in order to achieve their information security objectives as a part of their organizational management activities in line with their respective business, by investing considerable effort and resources in developing and operating these systems. This approach can be used to apply, develop, and operate the information management system actively within an organization. this study focused on analyzing how each specific phase of the information security management system affects information security performance, compared with previous studies, which generally focus on the information security control item in analyzing information security performance. The information security management system was analyzed empirically to determine how the Security PCDA cycling model affects information security performance.
