The number of wireless public network user is increasing rapidly. Security problem for user authentication has been increased on existing wireless network such as IEEE802.11 based Wireless LAN. As a solution, IEEE802.1x (EAP-MD5, EAP-TLS, EAP-TTLS), X.509, protocol or security system was suggested as a new disposal plan on this problem. In this study, we overview main problem on existing EAP-MD5 authentication mechanism on Wireless LAN and propose a SMS(Short Message Service) based secure authentication and accounting mechanism for providing security enhanced wireless network transactions.

With the growing acceptance of XML technologies, XML will be the most common tool for all data manipulation and data transmission. Meeting security requirements for privacy, confidentiality and integrity is essential in order to move business online and it is important for security to be integrated with XML solutions. Many policies require certain conditions to be satisfied and actions to be performed before or after a decision is made. Binary yes/no decision to an access request is not enough for many applications. These issues were addressed and formalized as provisions and obligations by Betti et Al. In this paper, we propose an authorization model with provisions and obligations in XML. We introduce a formal definition of authorization policy and the issues involving obligation discussed by Betti et Al. We use the formal model as a basis to develop an authorization model in XML. We develop DTDs in XML for main components such as authorization request, authorization policy and authorization decision. We plan to develop an authorization system using the model proposed.

국민의 편의성과 효율성 제고를 위한 온라인 대국민 서비스가 증가함에 따라 보안 사고들이 빈번하게 일어나며, 인적작원을 통해 많은 개인정보가 유출되고 있다. 이에 따라서 정부에서 ISMS와 PIMS 인증제도를 통하여 안정성을 확보하기 위한 제도를 내놓았다. 하지만 두 가지 인증제도의 중복항목으로 담당자들의 업무 부담이 늘며 이를 통합을 발표하였다. 저자는 인증제도의 인력항목을 좀 더 효율적으로 관리 할 수 방안을 제시하고자 한다.

As the number of recent information security incident occurrence increases, more and more workload and liability pressure are given to info-security professionals, which results in decrease of morale level of working groups in the field. In order to solve this problem, Korean government is providing various action plans to improve the morale level of info-security professionals, and also requiring financial companies to submit its own action plan of increasing morale of info-security professionals to Financial Service Agency. For this study, based on the previous studies and relevant professionals' interviews, we selected 16 critical morale increase variables, and performed survey for empirical analysis. As a result, 3 features; role, system, and relationship were presented as the main factor of morale increasement of info-security professionals. This study also suggests a decision making method of utilizing the developed morale measurement model for individual organizations.
