Recently, Internet web services including bulletin board of companies, public intuitions, or governments became the main ways of personal information leakage. However, it is hard to succeed to detect personal information and protect it from leakage manually by system administrators, because the number of web boards and attached files is so huge. Therefore, automatic scanning and filtering methods are needed to protect personal information like resident registration numbers from unexpected exposure. To do this, we developed a novel and advanced web security system for automatic personal information scanning and filtering.

Although online search engine service provide a convenient means to search for information on the World Wide Web, it also poses a risk of disclosing privacy. Regardless of such risk, most of users are neither aware of their personal information being exposed on search results nor how to redress the issue by requesting removal of information. According to the 2015 parliamentary inspection of government offices, many government agencies were criticized for mishandling of personal information and its leakage on online search engine such as Google. Considering the fact that the personal information leakage via online search engine has drawn the attention at the government level, the online search engine and privacy issue needs to be rectified. This paper, by examining current online search engines, studies the degree of personal information exposure on online search results and its underlying issues. Lastly, based on research result, the paper provides a sound policy and direction to the removal of exposed personal information with respect to search engine service provider and user respectively.

The Personal Information Protection Commission was launched in August 2020 as an integrated control tower for personal information protection, but several problems have been pointed out in the personal information protection operation system. First, despite the fact that Korea's personal information protection system has an integrated legal system that regulates both the public and private sectors, it has been pointed out that it is difficult to carry out smooth personal information protection functions due to incomplete integration of protection functions, such as the Financial Services Commission being in charge of personal credit information protection and the Korea Communications Commission being in charge of personal location information protection. Next, despite the increasing number of public sector personal information leakage incidents, there is a lack of personnel with expertise and specialized support organizations to efficiently investigate them, and there is a concern that the lack of an efficient response system to personal information infringement by global IT companies in Korea in the era of digital commerce may weaken the protection of citizens' personal information. In order to solve these problems, I reviewed overseas cases and literature and proposed the following measures. First, it is necessary to centralize the personal information protection supervision function for credit information and location information to the Personal Information Protection Commission. Second, it is necessary to secure expertise by securing specialized personnel and establishing specialized institutions to respond to public sector personal information leakage incidents. Third, it is necessary to revitalize the domestic agency designation system and establish an international cooperation system to protect people's personal information in the digital commerce era. I believe that these measures to develop the personal information protection system will lead to more systematic personal information protection.

Cloud computing technologies are utilized and merged in various domains. Cloud computing technology-based personal cloud service technologies provide mobility and free access by using user centered storages and smart devices such like smart phones and table PCs. Therefore, we should overcome limits on the storage by solving the capacity problems of devices to provide security services in the personal cloud environments It can be addressable to provide the convenience of various security technologies. However, there are some security threats inherited from existing cloud environments and the possibilities of information leakage when devices are lost or stolen. Therefore, we designed a framework for providing secure cloud services by adding objects, such as user authorization, access tokens, set permissions by key generation, and key management assignments, for user management in personal cloud environments. We analyzed the stability of the proposed framework in terms of irreverent use and abuse, access to insiders, and data loss or leakage. And we evaluated the proposed framework in terms of the security with access control requirements in personal cloud environments.

One of the hottest issues of security is information leakage of financial institution. Financial institutions including commercial banks are frequently threatened by attempts of leakage through hacking and vulnerability, and this information is centered on personal information of their clients. Through this study, I found out that security managers of financial institutions are trying to prevent the leaking of private information, but in fact most of them barely know where their personal information is. Even if they know where it is and trace the data, it is often found in unexpected places. Because there is a lot of waste in time and human resources as search is done manually, we have understood that responding to IT Compliance requires a lot of effort. This study is to improve IT Compliance response and protect information leakage through monitoring PC and servers, the main storage of personal information by automated system, periodically.

Because personal information files held by educational institutions include sensitive information such as personal school affairs information or health information, damages resulted from personal information leakage of educational institutions are expected to be serious. In order to respond to this problem, the Ministry of Education has expanded information security education targeting (personal) information security officers in educational institutions. However, a number of personal information leakage cases of public institutions occurred at educational institutions. Thus, this study, targeting information security education centers, through an empirical research, tries to confirm whether information security education supply is being properly provided for (personal) information security officers in educational institutions, and suggest the appropriate balance between education supply and education demand as the implication for the educational direction of information security education centers.

A USB flash drive is a portable storage device. For its promising moderate price, portability and high capacity USB flash drive users are increasing rapidly. Despite these advantages USB flash drives have critical problems as well. Such as personal information data leakage due to easy loss of the portable device. As these personal information leakage incidents increases various security measure solutions are produced and distributed. Despite these security measures and solutions it is not enough to perfectly protect personal data leakage. Hence the necessity of a more concrete, secure, user-friendly security measure solution is required. In this paper we provide you with portable USB flash drive security solution analysis and provide you with the latest secure, user-friendly security measure solutions.

Recently the leak of personal information from in-house and contract-managed companies has been continually increasing, which leads a regular observation on outsourcing companies that perform the personal information management system to prevent dangers from the leakage, stolen and loss of personal information. However, analyzing many numbers of computers in limited time has found few difficulties in some circumstances-such as outsourcing companies that own computers that have personal information system or task continuities that being related to company's profits. For the reason, it is necessary to select an object of examination through identifying a high-risk of personal data leak. In this paper, this study will formulate a proposal for the selection of high-risk subjects, which is based on the user interface, by digital forensic. The study designs the integrated analysis tool and demonstrates the effects of the tool through the test results.

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 digital transformation and remote work environment advanced by Covid-19 become more common, the scale of leakage damage to industrial secrets and personal information caused by information leakage attacks is increasing. Recently, advanced and persistent information leakage attacks have become a serious security threat because they do not quickly leak large amounts of information, but continuously leak small amounts of information over a long period of time. In this study, we propose a framework for detecting advanced and persistent information leakage attacks based on traffic characteristics. The proposed method can effectively detect advanced and persistent information leakage attacks using traffic patterns, packet sizes, and metadata, even if the payload is encrypted.
