EU의 GDPR(General Data Protection Regulation) 발효로 인해 유럽국가의 개인 정보 데이터를 활용하는 다국적 기업들이 규정에 맞는 데이터 보호정책을 수립하고 보안 투자를 강화하고 있다. 그러나 대다수의 기업들은 해커 등에 의한 사이버 보안을 위해서는 천문학적인 투자를 하고 있지만 기업 내 많은 직원들에 의한 실수나 고의에 의한 개인 정보 유출 방지에 대해서는 대처를 하고 있지 않다. 본 논문에서는 디지털 포렌식 기반의 앤드 포인트 실시간 모니터링 및 인간 행위 분석을 통한 앤드 포인트 개인 정보 보호 기능을 제공하여 기존의 사이버 보안에 국한된 통합 보안 관제의 효율성을 높이는 방안을 제안한다.

Inernet of Things(IoT) is interaction with each other, collecting, sharing, and analysing the data. IoT has been noted in combining the fields of medical service in particular. However, the security issue is caused, while IoT is receiving attention. U-Health and medical devices, which deal mainly the personal health information, is required to a high level of privacy and security of health information. This study analyzes cases of leakage of personal medical information, security of IoT, privacy flow, and the response strategies.

Today, the world is evolving into a huge community that can communicate with real-time information sharing and communication based on the rapid advancement of scientific technology and information. Behind this information, the adverse effects of information assets, such as hacking, viruses, information assets, and unauthorized disclosure of information assets, are continually increasing as a serious social problem. Each time an infringement of the invasion and personal information leaks occur, many regulatory policies have been announced, including stricter regulations for protecting the privacy of the government and establishing comprehensive countermeasures. Also, companies are making various efforts to increase awareness of the importance of information security. Nevertheless, information security accidents like the leaks of industrial secrets are continuously occurring and the frequency is not lessening. In this thesis, I proposed a customized security policy methodology that supports users with various business circumstances and service and also enables them to respond to the security threats more confidently and effectively through not a monotonous and technical but user-centered security policy.

모바일 인스턴트 메신저에 적용된 암호기술은 사용자들의 개인정보를 보호하는 역할을 한다. 메신저에 저장된 사용자의 개인정보는 일반적으로 사용자의 패스워드, 사용자 정보 및 기기 정보 기반으로 생성된 암호화 키를 통해 암호화되므로 높은 안전성을 갖는다. 이러한 암호기술의 특성 때문에 국가 법집행기관은 범죄단서 확보 및 사실 증명을 위한 증거 분석과정에 어려움을 겪는다. 그러나, 최근 모바일 인스턴트 메신저를 통해 발생하고 있는 일련의 범죄 사건들을 볼 때 정당한 접근 하에 범죄단서 확보를 위한 암호분석 기술은 활발히 연구될 필요가 있다. 본 논문에서는 10종의 모바일 인스턴트 메신저에 대한 TMTO 및 GAN 모델을 활용한 안전성 분석을 제시한다.

eID는 여러 편의성을 제공하지만, 개인정보보호의 불확실성에 대한 우려로 활성화가 쉽지 않다는 단점이 있다. 이미 선진국에서는 eID의 도입을 추진해 왔으며 특히 EU에서 적극적으로 시도한 바 있다. 안전한 eID 시스템을 위해서는 개인정보보호 뿐 아니라 시스템 자체의 보안에 대한 고려도 동시에 이루어져야 한다. 보안성이 신뢰되지 않는다면, 개인정보보호에 대한 신뢰도 존재할 수 없을 것이다. 본 고에서는 EU에서도 특히 활발한 움직임을 보이고 있는 독일의 eID 현황 및 보안 메커니즘을 살펴본다. 그리고 안전한 eID 시스템 구성을 위한 보안 요구사항을 분석한다.

Currently mobile messenger industry, based on mobile application, is growing. And it has aroused innovative change, offering services in various forms beyond the form simply sharing messengers. Also because messenger securities are becoming personalized and intelligent, the importance of more diverse mobile applications' securities is increasing. This study carries out the empirical study of the causal relationship that the factors of using application services influence on security recognition and security Intention of mobile securities, and consequentially impact upon protection of personal information of users. In order that, we present the research model which prime variables of SDT, which emphasized on natural immanent motivation of human, applied to. To verify the research model of this study empirically, we conducted a survey targeting the public and university students which have ever used mobile messenger applications. With this, we desire to contribute to emphasizing the significance of individual messenger security and playing a positive role to develop security guide for consumers. The path analysis results are as follows. First, perceived autonomy has a positive effect on both security awareness and security intention. Second, perceived competence has a positive effect on security intention. Third, perceived relatedness has a positive effect on both security awareness and security intention. Last, security awareness and security intention. have a positive effect on privacy protection behavior. Through emphasizing the importance of the security of the messenger of individuals and contribute to a positive role for development of the necessary security guidelines to consumers.

Privacy Protection Act of 30 March 2012 was performed. In general, personal information management to enhance security in the DB server has a security system but, PC for the protection of the privacy and security vulnerability analysis is needed to research on self-diagnosis. In this paper, from a PC to search information relating to privacy and enhance security by encrypting and for delete file delete recovery impossible. In pc found vulnerability analysis is Check user accounts, Checking shared folders ,Services firewall check, Screen savers, Automatic patch update Is checked. After the analysis and quantification of the vulnerability checks through the expression, enhanced security by creating a checklist for the show, PC security management, server management by semi-hwahayeo activates. In this paper the PC privacy and PC security enhancements a economic damage and of the and Will contribute to reduce complaints.

The traditional personal information life cycle model, primarily tailored to conventional systems, is inherently unsuitable for comprehending the nuances of personal information flow within artificial intelligence frameworks and for formulating effective protective measures. Therefore, this study endeavors to introduce a personal information life cycle model specifically designed for artificial intelligence (AI). This paper presents a personal information life cycle model suitable for artificial intelligence, which includes the stages of collection, retention, learning, use, and destruction/suspension, along with the re-learning process for destruction/suspension. Subsequently, we compare the performance of these existing models (such aspersonal information impact assessment and the ISMS-P model) with the newly proposed model. This underscores the superiority of our proposed model in comprehensively understanding the personal information flow in AI and establishing robust protective measures.

Recently, network forensic research which analyzes intrusion-related information for tracing of attackers, has been becoming more popular than disk forensic which analyzes remaining evidences in a system. Analysis and correlation of logs from firewall, IDS(Intrusion Detect System) and web server are important part in network forensic procedures. This work suggests integrated graphical user interface of network forensic for private information leakage detection. This paper shows the necessity of various log information for network forensic and a design of graphical user interface for security managers who need to monitor the leakage of private information.
