인터넷을 비롯한 대부분의 패킷스위칭 네트워크는 IP(Internet Protocol)을 기반으로 하고 있다. 그러나, IP는 기본적으로 보안에 취약하게 설계되어 보안이 필요한 통신에 사용하는데는 어려움이 있다. IPSec(IP Security)은 IP 트래픽에 대한 이러한 보안문제를 극복하기 위해 생겨났으며, 방화벽과 결합된 형태로 가장 널리 쓰이고 있는 VPN(Virtual Private Network) 제품의 하나이다. 그러나 IPSec의 문제점이 대두되고, Web-based Service가 영역을 넓혀가면서 기존의 웹보안프로토콜인 SSL이 VPN의 새로운 형식으로 나타나고 있다. 본 고에서는 IPSec VPN과 SSL VPN의 차이점의 분석하여 정리하고자 한다.

Recently the private security industry is showing rapid growth compared with the different types of industry. However, it is not prepared the device for the system to verify the professional qualification of the security guards. To protect individual life and property, body and security guards have to be qualified professionally. For it the role of professional qualification systems is emphasized. The problem of the certification of the qualification about the security guard to play the role to protect a body / life of the individual and property are the part to need necessarily as the quality problem of the individual and the trust of the people. The settlement of the qualification system which is such system can induce the development of the security industry with social trust. The certified security certification is needed and how to control the security quality to get better service to the clients. The professional qualification system to be carrying out with America and Japan is fixed through the cooperation of the business world and steady research for the qualification system plan, these are giving the trial of the qualification system of a security of Korea full of the suggestion. This study will do this to the basis which a necessity about the qualification system of the security man emphasis and considerate professional qualification system concerning the private security development plan around the Bodyguard Qualifying Examination which are carried out at twice by the Korea Security Association and the Korean Institute of Security. In summary to meet the social demand professional qualification for the security guards will be drawn from the analyses of civil security qualification systems.

The objectives of this study is to analyze the curriculum based on the hypothesis of bodyguarding related department and to research the differences of the amongthree groups of public bodyguarding, private bodyguarding and bodyguarding professors with its significance in order to establish the development of direction in education curriculum for bodyguarding related departments at university level,For this purpose, this study categorized the sample group into three kind and surveyed them, Those are public bodyguarding members, private bodyguarding member, and the professors and 121 samples were selected in those three with the help of self-admistrated method, which is one of the sampling methods, First, among the current bodyguarding related theoretical disciplines significant differences among groups was presented by the evaluations on bodyguarding science, traffic safety management, fire extinguishing, secretary science, administration, psychology, sports education, sport physiology, jurisprudence and philosophy, which showed differences among groups through the multiple comparison, But there was no significant difference among the means of the groups concerned with the other curriculum, We could know that more curriculum is needed to facilitate the private bodyguarding in disciplines and system of the current theory in this study. For it is predicted the demand for the private bodyguarding will increase continuously in the future. for which we should prepare. Thus it is required to increase the theoretical curriculum of the private bodyguarding. That is. the models of curriculum like introduction to machinary guarding. introduction to communication. computer theory and so on are required to be established. In addition to that. it must be noticed that the current private bodyguarding is not guaranteed by the legitimate institution. But the private bodyguarding is related to the police service. thus the curriculum of jurisprudence and police science should be studied together.

The purpose of this study is to find the development of the special security business plan based on the problem that guards are now aware of special security service. In order to achieve the objectives of this study, we analyzed the data after expert survey and interview conducted by seven experts engaged in special security services more than 10 years. The guard who perform special security service proposed a development plan of special security services as follows. First, the current education system for new employees' training is required to improve the educational program of 60 hours in subjects related to special security duties by reorganization. Second, the special security service training for guards also appropriate to switch to 9-hour training program for three months through an educational organization controlled by country. Third, the special security guards should be proceeding the practical programs required in the field and quality education in the different section by competent and professional instructors. Fourth, the retirement age for special security guard stipulated in the Security Services Industry Act that needs to be readjusted upward by considering the social environment. Sixth, there needs to be organized the Special Security Association for development associated with the special security service and to protect the rights of special security guards.

IETF에서 IPSec(Internet Protocol Security)[1]의 구조를 발표한 이래 IPSec을 이용한 많은 VPN(Virtual PrivateNetwork)[2][3]이 구축되어 왔다. 이렇게 구축된 VPN에서 사용되는 CG(CryptoGate) 혹은 SG(Security Gateway)는 각각의 망에서 게이트 역할을 한다. 하지만 이런 기존의 CG나 SG는 IPSec의 정책을 사용자가 선택하는 것이 아닌 망 관리자가 일방적으로 서비스하도록 설계되어있다. 이러한 점은 사용자가 자신의 데이터를 평가하여 자율적으로 그에 맞는 서비스를 이용하는 것이 아니므로 사용자가 사용하는 것을 꺼릴 수도 있다. 또한 게이트웨이에 자신의 키를 백업할 수 있도록 하여서 사용자가 다시 이 망에 접근할 경우 다시 키 협상을 하는 것이 아닌 백업해둔 키를 가지고 연결할 수 있도록 하였다. 본 논문은 VPN에서 이러한 점을 고려하여 CG를 설계함으로써 VPN 사용의 확장성을 해결한다.

The System of communication with wireless devices is experiencing a huge growth. While traditional communication paradigms deal with fixed networks, mobility raises a new set of questions, techniques, and solutions. In order to realize service mobility, there is a need of protocol that can support mobility while nodes are communicating without any disruption of their connection status. This paper proposes a handover authentication protocol for mobility support. Careful considerations must be taken in priority to security issues since many unreliable public and private resources; both networks and devices are involved. The protocol is based on public key cryptography with Diffie-Hellman algorithm which provides security against both leakage-resilience of private keys on untrustworthy devices and forward secrecy.

Thus in order to have a better understanding about the KSA(Korean Security association) and to express opinions on its role and security, this paper introduces and discusses about All Japan Security Service Association(AJSSA), which is the prototype of the KSA. There are several positive aspects to consider the introduction of, when these two associations are compared: the traffic security, a supporting member, ex-high-ranking police executive directors practically run AJSSA. These are to enhance financial ability and to promote better relationship with police. KSA needs to improve such relationship and to diversify activities as well. In addition, not just dismissing their duty by giving them the license, AJSSA provides several educations to revitalize the related people so that they can deal in effective and productive services. In another words, JSA perceives it is indispensable to educate the relevant people in the business. In contrast, it is reality that KSA has not put much emphasis on educations. Concisely, the most prompt issue is it should be more beneficial to its members by strengthening itself. Not simply following the example of foreign cases, but putting diverse efforts, KSA can make it substantial and stabilize future private security market in a long term.

Private specialized institutions differ from public ones in that they mostly act independently. This paper reports a study designed to assess the provision of specialized institutions for children with intellectual disabilities in Saudi Arabia. The approach taken in this study was qualitative, involving a case study strategy that enabled the researcher to gain rich and in-depth information based on the shared experiences of participants comprising institution leaders, educators and families from two specific specialized settings, one public and one private. The study aimed to examine the existing disparities in service delivery so as to develop a clear picture of the service quality provided by public specialized institutions for children with intellectual disabilities in Saudi Arabia. The results suggest that the weak relationship with inpatient and specialized institutions is a consequence of the parents' poor responsiveness, which may result in these institutes developing a negative impression of the parents. Conversely, the lack of active initiative on the part of the public specialized institutions led to a negative parental attitude towards these institutions. A sensible approach to resolving this problem might be to recognize that these institutions have a significant responsibility to encourage parents of children with intellectual disabilities to become involved in their children's learning, to promote positive attitudes.
