The Native API is a system call which can only be accessed with the authentication of the administrator. It can be used to detect a variety of malicious codes which can only be executed with the administrator's authority. Therefore, much research is being done on detection methods using the characteristics of the Native API. Most of these researches are being done by using supervised learning methods of machine learning. However, the classification standards of Anti-Virus companies do not reflect the characteristics of the Native API. As a result the population data used in the supervised learning methods are not accurate. Therefore, more research is needed on the topic of classification standards using the Native API for detection. This paper proposes a method for re-grouping malicious codes using fuzzy clustering methods with the Native API standard. The accuracy of the proposed re-grouping method uses machine learning to compare detection rates with previous classifying methods for evaluation.

Service environments through laptops, smart devices, and various IoT devices are developing very rapidly. Recent security measures in these Internet environments mainly consist of network application level solutions such as firewall(Intrusion Prevention Systems) and IDS (intrusion detection system). In addition, various security data have recently been used on-site, and issues regarding the management and destruction of such security data have been raised. Products such as DRM(Digital Rights Management) and DLP(Data Loss Prevention) are being used to manage these security data. However despite these security measures, data security measures taken out to be used in the field are operated to the extent that the data is encrypted, delivered, and stored in many environments, and measures for encryption key management or data destruction are insufficient. Based on these issues we aim to propose a SecureOS Module, an OS-based security module. With this module users can manage and operate security data through a consistent interface, addressing the problems mentioned above.

This paper studies desirable form of future e-government in terms of intelligent government research in response to new intelligent cyber security services in the fourth industrial revolution. Also, the strategic planning of the future e-government has been contemplated in terms of the centralization and intellectualization which are significant characteristics of the fourth industrial revolution. The new system construction which is applied with security analysis technology using big data through advanced relationship analysis is suggested in the paper. The establishment of the system, such as SIEM(Security Information & Event Management), which anticipatively detects security threat by using log information through big data analysis is suggested in the paper. Once the suggested system is materialized, it will be possible to expand big data object, allow centralization in terms of e-government security in the fourth industrial revolution, boost data process, speed and follow-up response, which allows the system to function anticipatively.

ICT산업의 발전과 전자상거래의 대중화에 따라 정보시스템에 대한 지능 고도화 된 사이버위협이 증가되고 있고, 개인 및 기업정보 유출의 피해규모가 커짐에 따라 정보보호의 중요성이 한층 더 부각되고 있다. 이미 세계 각국에서는 ISO27001, BS10012 등 정보보호 관리 제도를 구축하여 운영하고 있다. 이에 국내에서도 미래창조과학부 주관 정보보호 관리체계(ISMS:Information Security Management System) 인증제도를 비롯한 정보보호 제도를 구축하여 기업 정보자산의 안전과 신뢰성 향상 등의 목적으로 자율과 의무 대상을 구분하여 운영하고 있다. 하지만 기업의 규모와 환경, 매출 등에 따라 형평성 있게 구분하지 않은 현재의 정보보호 관리체계 인증제도에는 여러 모순이 존재한다. 통제항목을 비롯한 세부점검항목을 인증 기업을 대상으로 모두 공통으로 적용하기 때문이다. 본 논문에서는 정보 보호 관리체계 인증제도와 유사 인증체계를 비교하여 인증기준 항목을 기업의 규모와 특성에 따라 유형별로 구분하여 적용하는 방안을 연구하였다.

As digitalization accelerates, the use of digital information is increasing in public institutions such as schools and libraries, and the demand for print services is also increasing. Among many services, printing service on public PCs should charge fee to printer users, but it is a very difficult task for administrators. Print management solutions have been developed and are now widely used to automate these demanding tasks. In this paper, we analyze the vulnerability of printer management solutions used in public institutions. However, the security awareness of public PC administrators and printer management solution developers seem to be lacking.

In information security and network management, attacks based on vulnerabilities have grown in importance. Malicious attackers break into hosts using a variety of techniques. The most common method is to exploit known vulnerabilities. Although patches have long been available for vulnerabilities, system administrators have generally been reluctant to patch their hosts immediately because they perceive the patches to be annoying and complex. To solve these problems, we propose a security vulnerability evaluation and patch framework called PKG-VUL, which evaluates the software installed on hosts to decide whether the hosts are vulnerable and then applies patches to vulnerable hosts. All these operations are accomplished by the widely used simple network management protocol (SNMP). Therefore, system administrators can easily manage their vulnerable hosts through PKG-VUL included in the SNMP-based network management systems as a module. The evaluation results demonstrate the applicability of PKG-VUL and its performance in terms of devised criteria.

Existing web-based system management software solutions show some limitations in time and space. Moreover, they possess such as shortcomings unreliable error message announcements and difficulties with real-time assistance suppers and emergency measures. In order to solve these deficiencies, Wireless Remote Control System was designed and implemented. Wireless Remote Control System is able to manage and monitor remote systems by using mobile communication devices for instantaneous control. The implementation of Wireless Remote Control System leads to these security Problems as well as solutions to aforementioned issues with existing web-based system management software solutions. Therefore, this paper has focused on the security matters related to Wireless Remote Control System. The designed security functions include mobile device user authentication and target system access control. For security verification of these security functions introduced CPN(Coloured Petri Nets) which is capable of expressing every possible state for each stage. And then in this paper was verified its security through PI(Place Invariant) based on CPN(Coloured Petri Nets). The CPN expression and analysis method of the proposed security function can also be a useful method for analyzing other services in the future.
