현재의 네트워크 시스템은 보안시스템 및 신규시스템이 추가됨에 따라 복잡함이 증가하고, 그에 따라 관리하기가 어려워져 관리자나 사용자가 이용하기에 불편함이 따른다. 또한 사용자의 잦은 변동과 단말의 이동성으로 인해 네트워크 관리하는데 있어 관리자가 해야할 일들이 많아 졌다. 따라서 앞으로의 네트워크 관리도구는 복잡성을 해결하고, 사용자의 편의성에 중점을 두어야 한다. 이러한 요구사항을 정리하여 본 논문에서는 사용자에게는 보다 쉽게 사용하고, 관리자에게는 최소비용과 관리의 용이성을 위한 보안시스템을 설계하였다. 이 시스템은 신규 사용자의 네트워크 접속후 인증을 받기위한 부분에 있어서 리눅스 시스템과 네트워크 장비를 연동해서 관리자가 정책적용시 자동으로 ACL을 구성해 보안관리를 강화하는데 목적을 두고 설계하였다.

Ubiquitous 시대의 도래와 함께 RFID는 Ubiquitous 기술의 핵심적인 역할을 담당하고 있으며, RFID를 읽고 판독하는 단말기의 개발 역시 매우 중요한 기술개발 분야이다. 본 논문에서는 RFID중 현재 교통카드 등에서 많이 사용되고 있는 RFID 13.56Mhz와 보안회사에서 사용하고 있는 125Khz의 인프라를 그대로 사용할 수 있고, TCP/IP 통신을 통해 위치파악, 출입통제, 보안통제 등의 응용이 가능한 시스템을 모델링하고자 한다. 기존의 로컬 RFID 방식은 기업체 내에 별도의 서버를 두어 운영하기 때문에 관리문제, 기술문제 등의 애로사항이 빈번하게 발생하는 문제점이 있다. 따라서 본 논문에서는 이러한 문제점을 해소할 수 있도록 TCP/IP로 연결된 중앙관리 서버를 사용하여 보안통제가 가능하도록 시스템을 모델링함으로써 RFID 인프라의 설치, 이전 및 관리 등이 용이하도록 보안통제 시스템을 구성하였다.

Today, information security (INFOSEC) as a discipline is gaining more and more importance according to the emergence and extension of the cyberspace. Originated from Joint Doctrine for Information Operation (Joint Pub 3-13) by the U.S. Department of Defense, 'information assurance (IA)' is the concept widely used in the relevant field. Grown from the practice of information security, it encompasses broader and more proactive protection that includes countermeasures and repair, security management throughout an information system (IS)'s life-cycle, and trustworthiness of an IS in the process of risk analysis. In Korea, many industry professionals tend to misunderstand IA, remaining unaware of the conceptual differences between IA and INFOSEC. On this account, the current study attempted to provide a combined definition of IA by reviewing relevant literature. This study showed the validity of the wordings used in the proposed definition phrase by phrase.

Information security is an essential factor that enables terminal to be operated. However, despite of this importance of information security, there has hardly been any research related to this topic. And moreover, current level of information security performance in container terminals has not been analyzed so far. The objective of this study is to evaluate current level of information security in container terminals. Through survey from the four leading container terminal operators in Korea, The results firstly showed that average of information security level of major container terminals was 71.7%. And from the results of data analysis, it revealed that the weak point of information security in Korean container terminals was security management, and in detail, lack of expertise of support group.

The security control is to protect IT system from cyber infringement by deriving valid result values in the process of gathering and analyzing various information. Currently, security control is very effective by using SIEM equipment which enables analysis of systematic and comprehensive viewpoint based on a lot of data, away from analyzing cyber threat information with only fragmentary information. However, It can also be said that cyber attacks are analyzed and coped with the manual work of security personnel. This means that even if there is excellent security equipment, the results will vary depending on the user using. In case of operating a characteristic web service including information provision, This study suggests the basic point of security control through characteristics information analysis, and proposes a model for intensive security control through the type discovery and application which enable a step-wise analysis and an effective filtering. Using this model would effectively detect, analyze and block attacks.

As seen in recent cases of hacking in financial services, attackers are attempting to hacking trustee with poor security management, rather than directly hacking a financial company. As a result, the consignor is strengthening the security check and control of the trustee, but small trustee has difficulties to invest in information security with the lack of computer facilities and the excessive cost of security equipment. In this paper I investigate the vulnerability of personal information processing life cycle standards in order to enhance the security of small consignee that receive personal information form the credit card company. To solve the vulnerability the company should use litigation management system constructed on cloud computing service and install VPN to secure confidentiality and intergrity in data transfer section. Also, to enhance the security of users, it is suggested to protect personal credit information by installing PC firewall and output security on user PC.

As a way for defending against cyber security threats, there has been a research on cybersecurity information exchange between security management domains in order to raise security performance of the whole network. One of the hottest issues in exchanging cybersecurity information between security management domains is that the requirements of those domains on information sharing are different with each other because each is autonomous domain. This paper proposes a mechanism for effective cybersecurity Information exchange between independent security management domains, which can satisfy their requirements on information sharing through sharing policy and sharing policy control protocol, proposed in this paper. In this paper we have developed an integrated security control system that supports the proposed mechanism. Through the system the performance of the proposed mechanism is measured and evaluated.

In general, an information security approach estimates the risk, where the risk is to occur due to an unusual event, and the associated consequences for cloud organization. Information Security and Risk Management (ISRA) practices vary among cloud organizations and disciplines. There are several approaches to compare existing risk management methods for cloud organizations but their scope is limited considering stereo type criteria, rather than developing an agent based task that considers all aspects of the associated risk. It is the lack of considering all existing renowned risk management frameworks, their proper comparison, and agent techniques that motivates this research. This paper proposes Agent Based Information Security Framework for Hybrid Cloud Computing as an all-inclusive method including cloud related methods to review and compare existing different renowned methods for cloud computing risk issues and by adding new tasks from surveyed methods. The concepts of software agent and intelligent agent have been introduced that fetch/collect accurate information used in framework and to develop a decision system that facilitates the organization to take decision against threat agent on the basis of information provided by the security agents. The scope of this research primarily considers risk assessment methods that focus on assets, potential threats, vulnerabilities and their associated measures to calculate consequences. After in-depth comparison of renowned ISRA methods with ABISF, we have found that ISO/IEC 27005:2011 is the most appropriate approach among existing ISRA methods. The proposed framework was implemented using fuzzy inference system based upon fuzzy set theory, and MATLAB(R) fuzzy logic rules were used to test the framework. The fuzzy results confirm that proposed framework could be used for information security in cloud computing environment.

Recently, many biometrics-based user authentication schemes for telecare medicine information systems (TMIS) have been proposed to improve the security problems in user authentication system. In 2014, Mishra et al. proposed an improvement of Awasthi-Srivastava's biometric based authentication for TMIS which is secure against the various attacks and provide mutual authentication, efficient password change. In this paper, we discuss the security of Mishra et al.'s authentication scheme, and we have shown that Mishra et al.'s authentication scheme is still insecure against the various attacks. Also, we proposed the improved scheme to remove these security problems of Mishra et al.'s authentication scheme, even if the secret information stored in the smart card is revealed. As a result, we can see that the improved biometric based authentication scheme is secure against the insider attack, the password guessing attack, the user impersonation attack, the server masquerading attack and provides mutual authentication between the user and the telecare system.
