Many organizations need to comply with ISMS-P for information systems and personal information management for ISMS-P certification. Organizations should safeguard vulnerablities to information systems. However, as the kinds of information systems are diversified and the number of information systems increases, management of such vulnerabilities manually accompanies with many difficulties. SCAP is a protocol to manage the vulnerabilities of information system automatically with security standards. In this paper, for the introduction of SCAP in domestic domains we verify the applicability of server-oriented system which is one of ISMS-P certification targets. For SCAP applicability, For obtaining this goal, we analyze the structures and functions of SCAP. Then we propose schemes to check vulnerabilities of the server-oriented system. Finally, we implement the proposed schemes with SCAP to show the applicability of SCAP for verifying vulnerabilities of the server-oriented system.

Cloud computing is a currently developing revolution in information technology that is disturbing the way that individuals and corporate entities operate while enabling new distributed services that have not existed before. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services. Security is often said to be a major concern of users considering migration to cloud computing. This article examines some of these security concerns and surveys recent research efforts in cryptography to provide new technical mechanisms suitable for the new scenarios of cloud computing. We consider techniques such as homomorphic encryption, searchable encryption, proofs of storage, and proofs of location. These techniques allow cloud computing users to benefit from cloud server processing capabilities while keeping their data encrypted; and to check independently the integrity and location of their data. Overall we are interested in how users may be able to maintain and verify their own security without having to rely on the trust of the cloud provider.

Zen Cart is an open-source online store management system. It is used all over the world because of its stability and safety. Today, Zen Cart's session security mechanism is mainly used to verify user agents and check IP addresses. However, the security in verifying the user agent is lower and checking the IP address can affect the user's experience. This paper, which is based on the idea of session protection as proposed by Ben Adida, takes advantage of the HTML5's sessionStorage property to store the shared keys that are used in HMAC-SHA256 encryption. Moreover, the request path, current timestamp, and parameter are encrypted by using HMAC-SHA256 in the client. The client then submits the result to the web server as per request. Finally, the web server recalculates the HMAC-SHA256 value to validate the request by comparing it with the submitted value. In this way, the Zen Cart's open-source system is reinforced. Owing to the security and integrity of the HMAC-SHA256 algorithm, it can effectively protect the session security. Analysis and experimental results show that this mechanism can effectively protect the session security of Zen Cart without affecting the original performance.

With the rapid development of mobile technology the use of smartphone is spreading. In order to activate mobile banking and market in the future, the most important key is a secure financial transactoin. However, because many apps are developed without security check in proportional to the spread of smartphone, security threat is inevitably high. Current smartphone banking is processed as the way of the existing public certificate or OTP technique in the mobile environment, but many security hole about current technology is pointed out steadily. Therefore, in this paper we are to improve a existing security hole by reinforcing the security through multi-factor authentication and providing a physical non-repudiation.

최근 몇 년 동안 피싱, 파밍, 크라임웨어에 의한 피해 사례 발생이 증가되고 있다. 현재까지의 피싱 관련 솔루션이 대부분 블랙리스트 방식이고 아직까지 피싱 사이트 판단 기준이 없으며 사람들이 이에 대한 인식의 부족으로 인해 이러한 위협을 대처하는데 많은 한계를 가지고 있다. 이에 본 연구에서는 화이트 리스트 기반 웹사이트 보안수준 확인 시스템을 설계하고 이의 파일럿 시스템을 개발하였다. 각 사이트에 대해 피싱 관련 보안수준을 확인하여 신뢰할 수 있는 사이트들을 선별하고 보안수준 정보를 제공함으로써 안전한 인터넷 이용 기반을 제공할 수 있는 방안이 마련될 것으로 기대한다.

The objective of this study is to generally check the present situation of private security industry by analyzing the current situation of private security industry in Korea so as to find which policy base is reflected to amend law by analyzing the amendment process of private security law in order to suggest policy direction of private security industry in Korea. Viewing through amendment process of private security law, enhancing publicity and enterprise are not judged to form any definite policy base. They are merely interpreted to partially reflect enterprise under the strong base of publicity. Such policy base may cause overall stagnation of private security industry. For sound development of private security industry, it is required to get out of the existing policy direction so as to change policy base to the direction of enhancing enterprise of private security industry. The power of police for instruction and supervision should be largely transferred to Korea Security Association so as to cultivate autonomous purifying function of private security industry. Police should strive to develop policy in the level of joint production of security service.

Encryption is a method to convert information to no-sense code in order to prevent data from being lost or altered by use of illegal means. Audit logging creates audit log of users' activities, exceptions, and information security events, and then conserves it for a certain period for investigation and access-control auditing. Our paper suggests that confidentiality and integrity of information should be guaranteed when transmitting and storing important information in encryption. Encryption should consider both one-way encryption and two-way one and that encryption key should assure security. Also, all history related to electronic financial transactions should be logged and kept. And, it should be considered to check the details of application access log and major information. In this paper, we take a real example of encryption and log audit for safe data transmission and periodic check.

NIST in the United States has developed SCAP, a protocol that enables automated inspection and management of security vulnerability using existing standards such as CVE and CPE. SCAP operates by creating a checklist using the XCCDF and OVAL languages and running the prepared checklist with the SCAP tool such as the SCAP Workbench made by OpenSCAP to return the check result. SCAP checklist files for various operating systems are shared through the NCP community, and the checklist files include ID, title, description, and inspection method for each item. However, since the inspection items are simply listed in the order in which they are written, so it is necessary to classify and manage the items by type so that the security manager can systematically manage them using the SCAP checklist file. In this study, we propose a method of extracting the description of each inspection item from the SCAP checklist file written in OVAL language, classifying the categories through a machine learning model, and outputting the SCAP check results for each classified item.

To strengthen the security of autonomous vehicles, this study derived checklists through the analysis of the status of autonomous vehicle security. The analyzed statuses include autonomous vehicle characteristics, security threats, and domestic and foreign security standards. The derived checklists are then applied to the AHP(Analytic Hierarchy Process) model to find their relative importance. Relative importance was ranked as one of cyber security management system establishment and implementation, encryption, risk assessment, etc. The significance of this study is to reduce cyber security incidents that cause human casualties as well improve the level of security management of autonomous vehicles in related companies by deriving the autonomous vehicle security level checklists and demonstrating the model. If the inspection is performed considering the relative importance of the checklists, the security level can be identified early.
