Despite the recent growth in size and frequency of damages caused by illegal information breaches, current business counter-measures and precautionary systems are greatly limited. Some major companies have developed Information Security Management Systems (ISMS) to safeguard their vital information; however, such measures are largely based on the ISO27001 and lacks in many aspects to grasp the holistic corporate security level and reinforce precautionary measures. The information protection level evaluation model introduced in this paper is a pragmatic evaluative tool that can be utilized to devise effective corporate information security precautionary measures and countermeasures, based on the BSC (Balanced ScoreCard) method for an actual and realistic corporate information security level evaluation possible.

As Ransomware spreads, the target of the attack shifted from a single personal to organizations which lead attackers to be more intelligent and systematic. Thus, Ransomware's threats to domestic infrastructure, including the financial industry, have grown to a level that cannot be ignored. As a measure against these security issues, organizations use ISMS, which is an information protection management system. However, it is difficult for management to make decisions on the loss done by the security issues since amount of the damage done can not be calculated with just ISMS. In this paper, through FAIR-based loss measurement model based on scenario's to identify the extent of damage and calculate the reasonable damages which has been considered to be the problem of the ISMS, we identified losses and risks of Ransomeware on the financial industry and method to reduce the loss by applying the current ISMS and ISO 27001 control items rather than modifying the ISMS.

인터넷이 급속하게 확산되면서 그 동안 오프라인 환경에서만 가능하던 많은 일들을 사이버 상에서도 가능하게 해준 반면에 해킹이나 바이러스 등 새로운 보안위협도 증가하게 되었다. 최근 기업이나 조직에서는 산발적인 보안 관리에서 종합적이고 체계적인 정보보호관리체계가 요구되고 있으며 국내에서도 2001년 7월부터 정보보호관리체계(ISMS) 인증제도가 시행되어, 2009년 12월 현재 77개 업체(기관)가 인증을 받았으며, ISO27001 인증 건수도 100여건에 이르고 있다. 이와 같이 ISMS 인증제도가 국내에 도입된 이래 인증수요는 꾸준히 증가하여 기업경쟁력의 중요한 수단으로 인식되어 가고 있는 추세인 반면 ISMS 인증의 실수요자가 인식하는 인증의 효과성 등의 질적인 측면이 미흡하다는 문제는 끊임없이 제기되어 오고 있다. 본 고에서는 그동안 인증취득기관의 정보보호관리체계(ISMS) 인증 심사과정에서 지적된 결함사례를 분석하고, 국내 중소, 대기업들이 정보보호관리체계를 수립하여 운영하는 과정에서 공통적으로 나타나는 결함사항을 도출함으로써, 향후 기업들이 정보보호관리체계를 수립하는 과정에서 중점적으로 고려해야 할 사항들이 무엇인지 고찰하고자 한다.

Critical information infrastructure designations for cloud service providers continue to spread around the world as energy, financial services, health, telecommunications, and transportation sectors move to the cloud. In addition, in the case of Ukraine, the removal of restrictions on the use of cloud for national critical facilities and the rapid transition of critical data to the cloud enabled the country to effectively respond to cyberattacks targeting Russian infrastructure. In Korea, the ISMS-P is operated to implement a systematic and comprehensive information protection management system and to improve the level of information protection and personal information protection management in organizations. Control items considering the cloud environment have been modified and added to the audit of companies. However, due to the different technical levels of clouds between domestic and global, it is not easy to obtain information on the findings of cloud providers such as Microsoft for the training of domestic certification auditors on hyperscale scale. Therefore, this paper analyzes findings in hyperscale clouds and suggests ways to improve cloud-specific control items by considering the compatibility of hyperscale environments with ISO/IEC 27001 and SOC(System and Organization Control) security international standards.

As Internet usage is rapidly spreading, tasks that were only possible offline are now available in cyber space but at the same time, new security threats such as hacking and viruses have also increased. For that reason, Comprehensive and methodical information security systems are therefore required in enterprises and organizations. Consequently, the Information Security Management System certification system has been in effect in Korea since July 2001. As of December 2012, 130 enterprises have been certified, and more than 120 ISO27001 certifications have been issued. As such, since the introduction of the ISMS certification system in Korea, the demand for the certification has been steadily increasing, and it is now recognized as an integral part of maintaining the competitiveness in an enterprise. However, the qualitative aspects of certification regarding the effectiveness of ISMS have been continuously questioned by actual customers. In order to clarify the situation and remove such doubts, this study will substantiate the fact that development and certification of ISMS positively affect the business performance of enterprises so that they will recognize the effect of obtaining ISMS certification and eventually prevent security accidents and improve their business performance by developing ISMS.
