Recently, network technology has been used in various fields due to development of network technology. However, there has been an increase in the number of attacks targeting public institutions and companies by exploiting the evolving network technology. Meanwhile, the existing network intrusion detection system takes much time to process logs as the amount of network log increases. Therefore, in this paper, we propose a Spark-based network log analysis system that detects unstructured network attack pattern. by using Snort. The proposed system extracts and analyzes the elements required for network attack pattern detection from large amount of network log data. For the analysis, we propose a rule to detect network attack patterns for Port Scanning, Host Scanning, DDoS, and worm activity, and can detect real attack pattern well by applying it to real log data. Finally, we show from our performance evaluation that the proposed Spark-based log analysis system is more than two times better on log data processing performance than the Hadoop-based system.

기업활동에서 IT에 대한 의존도가 증가함에 따라 기업들은 다양한 소프트웨어 및 하드웨어 플랫폼에서 제공되는 서비스들을 운영하고 있다. 서비스들이 보급, 확대되는 과정에서 새로운 보안 취약점들이 나타나고, 이들 취약점을 악용한 기업정보의 유출 및 해킹 등 보안사고의 발생도 비례하여 증가하고 있다[1]. 특히 다양한 유형의 사업을 운영하는 지주회사 또는 대기업 그룹사의 경우, 사업영역별로 운영 중인 IT 인프라의 보안 취약점이 네트워크로 연결된 타 사업용 IT 인프라에 대한 사이버 침해의 통로로 악용될 가능성이 있다. 이 같은 문제의 해결을 위해 기업들은 사업영역 별로 보유한 IT 인프라의 보안 취약점 진단과 대응을 위한 솔루션들을 도입, 운영해 오고 있다. 하지만 기업의 보안 거버넌스 관점에서 보안 취약점 관리도 전사적인 보안 정책과의 연계 강화, 투자 중복의 방지, 효과적인 관리와 통제에 대한 필요성이 대두되기 시작했다. 보안 거버넌스 체계 강화에 대한 기업의 요구변화에 맞춰 보안 취약점의 통합관리를 지원하는 상용 솔루션들이 일부 출시되고 있으나 기업들이 기 운영하고 있는 개별 취약점 진단 솔루션과의 연동, 로그관리 및 기업이 요구하는 특화된 기능 구현 등의 어려움이 도입에 장애가 되고 있다. 따라서, 대기업을 중심으로 개별 보안 취약점 진단 솔루션들을 연동하여 기업보안 거버넌스를 효과적으로 지원할 수 있도록 취약점 관리업무 프로세스의 재설계와 함께 취약점 진단 통합관리 체계를 구축하고 있다[2][3][4]. 본고는 보안 취약점 관리업무의 문제점을 소개하고, 최근 대 기업을 중심으로 활발히 구축이 추진되고 있는 웹 기반의 취약 점 진단 통합관리 체계의 개념, 기능 및 운영 프로세스를 소개한다. 아울러, 기업 IT 인프라에 대한 보안 취약점 진단 데이터를 축적하여 기업 내부의 보안위험 요소를 사전예측하고, 정보보호의 투자 대비 효과(ROSI: Security Return on Investment)를 효과적으로 산정하는 인프라로서 활용 가치를 소개한다.

The globalizing economic processes based on knowledge-based economic systems have changed the environment of competition between corporations fundamentally. As a result, all corporations must carry out their own activities for innovation in order to strengthen their competitiveness continuously. However, it may be difficult for the companies to meet the demand of rapidly changing markets as well as technological changes by themselves. Therefore, most of companies intensify their interdependent collaboration with other corporations for carrying out innovative activities. This is a process of building innovation networks. Innovation networks can provide opportunities to learn latest technologies and at the same time reduce uncertainties for the future. In fact, innovation networks enable not only to provide information about technology, market etc. but also to create learning processes between innovative actors. Thus, innovation networks are the most significant factor to stimulate innovative activities as well as to generate the growth of companies. This paper argues about impacts of innovation networks on the result of innovative activities. Furthermore, this focuses on the analysis of characters of corporations as well as patterns between innovation networks and innovation results.

The value chain is analytically useful for the cultural industry that has the characteristics of both manufacture and service industry, as the focus of value chain analysis moves from manufacturing only to the other stages of activity involved in supplying goods and services to consumers. The aim of paper is to analyse the value chain of the cultural industry in Gyeongbuk, find out the strengths and weaknesses of it, and suggest the ways to enhance the innovation capabilities of cultural industry in Gyeongbuk. First, the firms in advertisement & marketing, and circulation & distribution have low percent in cultural industry and need the low level of human resource, but produce high value-added in value chain; so, we should facilitate the make-up of the firms in advertisement & marketing, and circulation & distribution. Second, we should strengthen inter-firm networks to facilitate the ex-change of the equipment, human resource, information and technology between them. Third, we should construct the system to development human resource with two levels and spread the open atmosphere of firms.

In the phono-sapiens era of the intelligence information society, most business activities are increasingly dependent on networks and information systems. SMEs, which occupy the majority of Korean companies, are increasingly possessing the value and technology of their information assets, and their ability to protect core technologies that are the driving force of corporate growth will be the most important competitiveness of enterprises. Accordingly, the Ministry of Science and ICT and the Korea Internet & Security Agency(KISA) provides a foundation for minimizing the damage from cyber threats such as hacking and information leakage by evaluating the current information protection level of SMEs and enhancing information protection capability by supporting a high level of customized information protection consulting. In this study, we analyze the effectiveness of information protection based on the results of KISA SMEs consulting. In addition, by identifying problems and limitations derived from SMEs information protection consulting results, SMEs should propose measures to improve information security of SMEs that can manage information protection management system more efficiently and effectively.

Since the advent of the internet as representative of the development of information communication technology (ICT), information transfer forms have changed rapidly these days. In the new techno-economic paradigms, I would ultimately consider how spatial structures of a knowledge-based service industry have been altered dynamically. To delve into this background, this study conducts an empirical case study of the internet advertising industry, particularly, among the whole advertising industry. Therefore, the primary objective of this study is to identify dynamic characteristics of spatial networks among actors for knowledge creation in Korea's internet advertising industry. In addition, it also is to analyze the formative elements of spatial networks which would have an influence on constructing the space of new economic activities. There are multilateral approaches. This research is classified into types of actors such as inter-firm, intra-firm, and firm-customer, and categorized according to spatial ranges such as local, regional, global levels. In the meanwhile, formative factors of the spatial networks could draw a conclusion from two aspects: inter-firm networks in the process of business in the internet advertising industry, and individual networks in the nonoccupational aspect. Accordingly, the results of this study suggest that actors' networks of two perspectives would make mutually complementary relationships and create new relational spaces in the digital economy.

Corporate business clusters create a borderless business network through value chains and value creation activities. Clusters in the IT sector are crossing regional boundaries because of their rapid technological development and short product life cycle. To investigate this phenomenon, we examined the value activities of IT companies. As a result, the global expansion of the case companies was limited, but they had business clusters that exceeded the regional boundaries. However, because the order of business clusters is not advanced, value activities are focused on productivity rather than innovation. Given the rapidly evolving nature of IT, it is necessary to evolve into a business cluster that can create new value. Companies must design and implement value-creating processes to develop new technologies or enter new markets, which can lead to cluster growth. Companies must design and implement value-creating processes to develop new technologies or enter new markets, which can lead to cluster growth.

Recently, comics pulication industry is experiencing long-time recess in Korean market. To overcome the difficulties firms are trying to develop various tools which fit new technological environments, but previous research tend to have focused too much on web-base contents such as webtoons, rather than communication effectiveness through social network services. Thus, this study investigated the relationship between the characteristics of postings at social network service and the consumer responsiveness. In the results, we found that posting with visual images and event invitations were positively associated with consumer responsiveness, and the amount of information was negatively associated with the responsiveness. This study shows some implications on how firms can effectively enhance communication with consumers through social network service.
