Since 2008, large-scale personal information breach incidents have occurred frequently. Even though national education, policy, and laws have been enacted and implemented to resolve the issue, personal information breaches still occur. Currently, individuals cannot confirm detailed information about what personal information has been affected, and they cannot respond to the breaches. Therefore, it is desirable to develop various methods for preventing and responding to personal information infringement caused by breach and leakage incidents and move to privacy protection behaviors. The purpose of this study is to create understanding of personal information security and information breach, to present services that can prevent breaches of personal information, to investigate the necessity of and analyze the potential public demand for such services, and to provide direction for future privacy-related information services.

The smart grid, a new open platform, is a core application for facilitating a creative economy in the era of the Internet of Things (IoT). Advanced Metering Infrastructure (AMI) is one of the components of the smart grid and a two-way communications infrastructure between the main utility operator and customer. The smart meter records consumption of electrical energy and communicates that information back to the utility for monitoring and billing. This paper investigates the impact of a cybersecurity attack on the smart meter. We analyze the cost to the smart grid in the case of a smart meter attack by authorized users based on a high risk scenario from NESCOR. Our findings could be used by policy makers and utility operators to create investment decision-making models for smart grid security.

Currently, cybersecurity technologies are primarily focused on defenses that detect and prevent cyberattacks. However, it is more important to regularly validate an organization's security posture in order to strengthen its cybersecurity defenses, as the IT environment becomes complex and dynamic. Cyberattack simulation technologies not only enable the discovery of software vulnerabilities but also aid in conducting security assessments of the entire network. They can help defenders maintain a fundamental level of security assurance and gain control over their security posture. The technology is gradually shifting to intelligent and autonomous platforms. This paper examines the trends and prospects of cyberattack simulation technologies that are evolving according to these requirements.

4차 산업혁명 시대가 도래함에 따라 사물인터넷(IoT)이 다양한 산업의 영역에서 활용되고 있다. 특히 IoT 기술 및 서비스를 활용하는 분야 중 하나인 스마트 의료 분야는 최근 소프트웨어 및 네트워크의 연결성이 강화되면서 사이버보안 사고가 급증하고 있다. 따라서 스마트 의료 기기·서비스 개발단계부터 보안을 고려하여 안전하게 개발하는 것이 필요하며, 서비스 제공시에도 보안을 고려하여 안전하게 관리 및 서비스를 제공하는 것이 필요하다. 이에 본 연구에서는 IoT 서비스 활용 분야 중 스마트 의료 분야에서 원격의료 서비스의 개인정보 침해 요인을 도출하고 이를 토대로 어택트리 기반의 시나리오 분석을 수행하고자 한다.
