Information protection system (Information protection system)-based IT environment built popularity in public agencies and businesses take advantage of the resources for the integration of the information system one essential environment began to recognize, cloud systems (Cloud System), cloud security (Cloud Security), big data (Big Data), big data security (Big Data Security), industrial security (Security Industry), as well as the issue. Due to the influence of these information protection system (Information protection system) in response to my external security threats based on the analysis plan. In this paper, data protection systems (Information protection system), resulting in the introduction, there are a number of security threats and particularly industrial security aspects and internal and external security threats in response by lighting about aspects of the plan is based on knowledge.

The Internet of Things (IoT), which is emerging as a future economic growth engine, has been actively introduced in areas close to our daily lives. However, there are still IoT security threats that need to be resolved. In particular, with the spread of smart homes and smart cities, an explosive amount of closed-circuit televisions (CCTVs) have been installed. The Internet protocol (IP) information and even port numbers assigned to CCTVs are open to the public via search engines of web portals or on social media platforms, such as Facebook and Twitter; even with simple tools these pieces of information can be easily hacked. For this reason, a big-data analytics system is needed, capable of supporting quick responses against data, that can potentially contain risk factors to security or illegal websites that may cause social problems, by assisting in analyzing data collected by search engines and social media platforms, frequently utilized by Internet users, as well as data on illegal websites.

This study is to analyze trends and relational structures in the energy sector related to renewable energy. For this reason, in this study, we focused on big data including SNS data. SNS utilizes the Instagram platform to collect renewable energy hash tags and use them as a word embedding method for big data analysis and social network analysis, and based on the results derived from this research, it will be used for the development of the renewable energy industry. It is expected that it can be utilized.

The information protection systems of company are intended to detect all weak points, intrusion, document drain. All actions of people in company are recorded and can check persistently. On the other hand, what analyze security log generated by these systems becomes more difficult. Most staff who manages the security systems, and analyze log is more incomprehensible than a user or a person of drain for an information distribution process of the work-site operations and the management procedure of the critical information. Such a reality say the serious nature of the internal information leakage that can be brought up more. While the research on the big data proceeds actively recently, the successful cases are being announced in the various areas. This research is going to present the improved big data processing technology and case of the security field.

Currently, the security control market is operating based on AI technology. The reason for using AI is to detect large amounts of logs and big data between security equipment, and to alleviate time and human problems. However, problems are still occurring in the application of AI. The security control market is responding to many problems other than the problems introduced in this paper, and this paper attempts to deal with five problems. We would like to consider problems that arise in applying AI technology to security control environments such as 'AI model selection', 'AI standardization problem', 'Big data accuracy', 'Security Control Big Data Accuracy and AI Reliability', 'responsibility material problem', and 'lack of AI validity.'

최근 급증하고 있는 고도화된 사이버 공격은 많은 피해를 낳고 있다. 이러한 문제를 미연에 방지하기 위해 각종 보안 솔루션의 도입으로 보안 시스템 환경이 복잡하게 변하게 되었다. 보안 관리자는 복잡한 환경으로 인해 보안 시스템 관리의 어려움으로 우수한 보안 솔루션이 있음에도 위협에 제대로 대처하지 못하고 있다. 본 논문에서는 보안시스템을 체계적으로 관리할 수 있고, IT 시스템에서 생성되는 이벤트와 로그를 통합해 늘어나고 있는 보안 위협에 적절한 대응이 가능하도록 도와주는 보안 시스템 관리 솔루션인 SIEM(Security Information and Event Management)에 대해 알아보고자 한다. 고도화되고 있는 사이버 공격과 복잡해진 클라우드 컴퓨팅, 데이터가 대량화됨에 따라 생겨난 빅데이터, 갈수록 강화되고 있는 컴플라이언스 요구사항을 만족할 수 있는 방안을 모색해봄으로써 SIEM이 앞으로 나아가야 할 방향에 대해 알아보고자 한다.

By building an environment that can utilize big data, many companies are interested in the cloud computing technology that has increased its popularity recently. By developing cloud environments from existing virtual environments, in the process, we discovered a variety of security vulnerabilities such as management, virtual machines, hypervisors, hardware etc. The security techniques from administrative aspects in the cloud environment provide the environment which can securely store data by the identification and control of security threats. In this paper, we investigate a list of companies which supports the cloud services and the types of services, and analyze the security threats according to the administrative aspects in the cloud environment. In addition, we suggest the direction for future improvements by investigating accidents or incidents which occurred recently.

Among methods of the big data process, big data process under the cloud environment is becoming a main topic. As part of solving faced problem and strengthening industrial competitiveness in the medical and health industry, discussion on ways to activate big data is actively being conducted. Because the reason is a paradigm shift, saving pressure for increasing health care costs, and increased consumer interest for the level of service. In this paper, we find out the relationship between the cloud and big data. And we are to research and analysis a cloud-based big data case in the medical field. Finally we propose the efficient utilization and future outlook. For the smooth functioning of cloud-based medical big data, we have to solve the problems like infrastructure extension, analysis/application software development, and professional manpower training. In addition, we have to correct insufficient laws maintenance to the Cloud utilization, and improve the security and the recognition to personal information, and solve authority for data centralization.
