Purpose: Natural Disaster has well formed framework more than social disaster, because natural disaster is controlled by one department, such as MOIS, but social disaster is distributed. This study is on the design of the integrated service platform for the social diaster data. and then, apply to the local governments. Method: Firstly, we design DB templates for the incident cases considering the incident investigation reports. For the risk management, life-damage oriented social disaster risk assessment is defined. In case of the real-time incident data from NDMS, AI system provides the prediction information in the life damage and the cause of the incident. Result: We design the structured and unstructured incident data management system, and design the integrated social disaster and safety incident management system. Conclusion: The integrated social disaster and safety incident management system may be used in the local governments

최근 해외 각국에서는 전산망 해킹 등 침해사고를 신속히 처리 및 대응할 수 있는 체계적인 업무시스템의 개발과 운영을 통해 침해사고를 효과적으로 처리하고 지원할 수 있는 체제를 구축하고 있다. 하지만 국내에서는 침해사고를 종합적으로 대응할 수 있는 체제의 미비로 침해사고에 대한 효율적인 대응에 어려움이 많다. 따라서 본 논문에서는 종합적이고, 체계적인 침해사고 대응업무 시스템의 설계와 구현 및 운영을 통해 전산망 침해사고의 신속한 처리와 대응의 기반을 마련하고자 한다.

클라우드 컴퓨팅은 사용자들의 직접적인 인프라 관리 없이 가상 스토리지, 네트워크, 컴퓨팅 리소스 등을 빠르게 고객에게 제공해주는 서비스이다. 클라우드 컴퓨팅은 누구나 외부에서 접근할 수 있으며 운영 담당자가 모든 클라우드 인프라를 직접 관리하기 어렵기 때문에 보안이 기존 인프라 보안과는 차별화된 운영 방법이 필요하다. 또한, 관리자가 온프레미스 기존의 사고 대응 프로세스를 클라우드 인프라에 적용하기에는 리소스 부족, 사고확산방지, 포렌식 등이 논리적, 물리적으로 어려움이 존재하여 클라우드 환경에서 적용가능한 자동화된 IR(Incident Response)의 모델을 설계하여 자동화된 사고대응 프로세스를 새롭게 제안 한다.

Since the September 11, 2001, the United States has shift their national security policy for homeland from preventing or/and reducing foreign threats to ensuring domestic security. We learned from recent incident, 1.25 Internet Disaster, that it is urgent to establish cyber security policy for our nation. In this paper; therefore, I analyze the US homeland security policy, the Homeland Security Act of 2002 establishment, and cyber security-related part in this act.

Today the protection of high-tech is one of the most important requirements to survive in competition between companies or countries. In these circumstances, government's industrial security activities have been transformed into independent activities of the private center. So, Company has introduced a high-tech security system for the sake of Technology protect. But, Several Security Incident have occurred in recent years, and so New security measures became necessary. In this study, I will suggest a new high-technology protection system model Using the social engineering techniques to analyze security threats.

Security quad and cube (SQC) is a network attack analyzer that is capable of aggregating many different events into a single significant incident and visualizing these events in order to identify suspicious or illegitimate behavior. A network administrator recognizes network anomalies by analyzing the traffic data and alert messages generated in the security devices; however, it takes a lot of time to inspect and analyze them because the security devices generate an overwhelming amount of logs and security events. In this paper, we propose SQC, an efficient method for analyzing network security through visualization. The proposed method monitors anomalies occurring in an entire network and displays detailed information of the attacks. In addition, by providing a detailed analysis of network attacks, this method can more precisely detect and distinguish them from normal events.

In the past few years, data leakage of information assets has become prominent issue. According to the NIS in South Korea, they found 375 cases of data leakage from 2003 to 2013, especially 49 of cases have been uncovered in 2013 alone. These criminals are increasing as time passes. Thus, it constitutes a reason for establishment, operation and certification of ISMS, even for private enterprises. The purpose of this study is to examine the factors influencing the certification intention of ISMS using EFA (Exploratory Factor Analysis) and regression analysis. We identified expectation factors for certification of ISMS from 13 elements using EFA (Strengthening practical ability & economic effect factor and Improvement of security level & handling incident factor). Next, we examined that the certification intention of ISMS using regression analysis. As a result of regression analysis, Strengthening practical ability & economic effect factor is not significant for the certification intention of ISMS (p<.05). Also, Improvement of security level & handling incident factor have a significant and positive effect on the certification intention of ISMS (p<.05).

The number of security incidents is increasing as the Internet of Things(IoT) is distributed widely. The security incidents of IoT can cause financial damages. Moreover, It can become direct threats to humans. In order to prevent these problems, the security installation for IoT devices is important. This paper describes the definition of IoT devices, security incident case, architecture, and the security threats that can occur when a device is connected to network without security installation.

With the increasing trend of Cloud migration, security threats in the Cloud computing environment have also experienced a significant increase. Consequently, the importance of efficient incident investigation through log data analysis is being emphasized. In Cloud environments, the diversity of services and ease of resource creation generate a large volume of log data. Difficulties remain in determining which events to investigate when an incident occurs, and examining all the extensive log data requires considerable time and effort. Therefore, a systematic approach for efficient data investigation is necessary. CloudTrail, the Amazon Web Services(AWS) logging service, collects logs of all API call events occurring in an account. However, CloudTrail lacks insights into which logs to analyze in the event of an incident. This paper proposes an automated analysis framework that integrates Cloud Matrix and event information for efficient incident investigation. The framework enables simultaneous examination of user behavior log events, event frequency, and attack information. We believe the proposed framework contributes to Cloud incident investigations by efficiently identifying critical events based on the ATT&CK Framework.

This paper focuses on how the protection of information security incident is effective in via Information security awareness when conducting information security activities of enterprises. Research models have theorized that the information security activity and the information security awareness will reduce the incidence of information security. The general characteristics of analysis targets have been carried out in the frequency analysis, and the reliability of the measuring tool has been utilized to calculate the coefficient of Cronbach's information protection. Evidence has been demonstrated regarding the relationship between information security activities and information security awareness and information security incidents.
