In the 1980s, private security was established in the framework of institutional framework with the Security Industry Act which was enacted in 1976. The agents who brought in the development of the private sector in 1980 enjoyed a boom in the global economy, affected by its high-flying dollar value, low international interest rate, low oil prices, and the blooming economy. In addition, the semiconductor, computers and communications equipment that was promoted in accordance with the e-Literacy plan were raised. Following the economic development of various events such as Seoul International Trade Fair, "86 Asian Games," and "88 Seoul Olympic Games," private security expenses were enhanced by increasing awareness of civilian expenses. Also, in the 1980s, Korean investment in foreign companies, including Japan's Secom, or Korean technology, brought many changes to the private security. Meanwhile, the cost of security, which has been centered around human expenses, has brought about the era of mechanized spending, or machine security expenses. The purpose of this study is to systematically analyze the social environment surrounding the private security in the 1980s and systematically analyze the important factors that contribute to private security.

This research looks close the effect of security agent's hierarchical leisure constraint on the leisure motivation and participation based on the Jackson's Model of the hierarchical leisure constraints. This research selected 420 people for sampling, designating security agents who work for security companies located in Seoul in 2009 at present as subjects by utilizing purposive sampling method, but the number of sampling used for ultimate analysis is 356. In this research, reliability analysis's and structural equation modeling's Maximum Likelihood method are used to prove the reliability and validity of questionnaire. By using these research method and procedures, the conclusion of this research is as following. First, intra-personal leisure constraint was affected by interpersonal, structural leisure constraint. Second, leisure motivation was affected negatively by leisure constraint. Third, leisure participation was affected positively by leisure motivation. Synthesizing all things referred above, leisure constraint was affected by inter-personal, structural leisure constraint, and in turn, leisure motivation and leisure participation were affected by its effects. It turned out that leisure motivation has a meaningful effect on leisure participation through leisure participation and adjusting process.

This research presents the development of a certain highly efficient model for group security policy negotiation using mobile agents in the IPSec environment. The conventional IP security systems has some problems. A drawback to these systems is that the required policy between each security area is different. Another problem is not possible to guarantee whether a packet is transmitted through the same path by both directions and is protected by the same policy due to the topology of the network. Unlike conventional systems, the model developed herein can be resolved by using a mobile agent technology. If each domain needs a negotiation of security policy, a mobile agent manages the result of the negotiation in the form of a passport and guarantees the authentication and reliability each other by using the passport.

Various terrorism in modern society against nation's dignitaries are constantly existing. They damage severely to the society and the nation's security, and they cause disorganizations of social and national rule orders. In order to provide the key figures' perfect protection, the threatening terroizing environment for primary leaders and the route of terrorism should be intercepted. Effective methods of these are summarized as follow. First, recent terrorism against the primary leaders are mostly assassinations, bomb attacks, and suicide bomb attacks, which terminate in a moment. Therefore, security service agents should keep in mind that protection is the best, and government's anti-terrorism agencies should develop policies and set the directions within a new paradigm to the advance anti-terrorism. Second, advance prevention activities against nation's VIP terrorism should be strengthened, such as strengthening security informational activities, constructing cooperative systems of domestic and international facilities, considering continuous system to prevent terrorism, and intensifying safety counterplans of human and material weak points. Third, international cooperative system should be set to apply economical and political sanctions to nations which support terror organizations in direct or indirect ways, and this system needs to strengthen the punishment against terrorists. Fourth, security systems to protect nation's primary leaders should complement, and developing programs for coping with the terrorism and establishing laws for anti-terrorism should be made. Also, educational training of agents who perform anti-terrorism duties should be strengthened, and scientific techniques and equipment for security should be made to protect primary leaders from terrorism.

For multiple attacks through large networks e.g., internet, IDS had better be installed over several hosts and collect all the audit data from them with appropriate synthesis. We propose a new distributed intrusion detection system called SPIDER II which is the upgraded version of the previous standalone IDS - SPIDER I. As like the previous version, SPIDER II has been implemented on Linux Accel 6.1 in CNU C. After planting intrusion detection engines over several target hosts as active agents, the administration module of SPIDER II receives all the logs from agents and analyzes hem. For the world-wide standardization on IDS, SPIDER II is compatible with MITRE's CVE(Common Vulnerabilities and Exposures).

The most of intrusion detection methods do not detect intrusion when it happens. To solve the problem, we are studying a real-time intrusion detection. Because a previous intrusion detection system(IDS) is running on the host level, it difficult to port and to extend to other system on the network level that distributed environment. Also IDS provides the confidentiality of messages when it sends each other. This paper proposes a model of real-time intrusion detection using agents. It applies to distributed environment using an extensibility and communication mechanism among agents, supports a portability, an extensibility and a confidentiality of IDS.

This study is to investigate how security organizational mentoring type and mentoring function affects organizatio nal commitment. This study had selected security from 5 different security organizations of 2010 which are located i n capital area. Using judgment sampling method, 198 security were drawn for the final study. The survey used in th is study is composed of 37 questions. To practice frequency analysis, factorial analysis, reliability analysis and regre ssion, a program called SPSSWIN 18.0 was used. The value of Cronbach's ${\alpha}$, which shows the reliability of the stud y, appeared to be over .622. The result is: First, security organizational mentoring type affects mentoring function. T hat is, when a systematic mentoring is activated, friendship protecting function, career managing function and sociopsychological function are promoted. Second, security organizational mentoring type affects organizational commitmen t. That is, when a systematic mentoring is activated, organizational commitment is promoted. Third, security organiz ational mentoring function affects organizational commitment. That is, increased friendship protecting function, career managing function, socio-psychological function and role model function results in increased organizational commitment.

A mobile agent is a program which is capable of migrating autonomously from host to host in the heterogeneous network, to perform some computation on behalf of the user. Mobile agents have many advantages in the distributed computing environment. But they are likely to suffer many attacks on the security due to the mobility. In order to make use of a mobile agent in the real applications, the security issues must be addressed. We deal with the problem which is concerned with protecting a mobile agent in transit and detecting a mobile agent clone. In this paper we propose a trust center based secure mobile agent transfer protocol. This protocol transfers a mobile agent securely from host to host and detects a mobile agent clone. We further show the security of the protocol against many attacks.

The attackers on Internet-connected systems we are seeing today are more serious and technically complex than those in the past. So it is beyond the scope of amy one system to deal with the intrusions. That the multiple IDSes (Intrusion Detection System) coordinate by sharing attacker's information for the effective detection of the intrusion is the effective method for improving the intrusion detection performance. The system which uses BBA (BlackBoard Architecture) for the information sharing can be easily expanded by adding new agents and increasing the number of BB (BlackBoard) levels. Moreover the subdivided levels of blackboard enhance the sensitivity of the intrusion detection. For the simulation, security models are constructed based on the DEVS (Discrete EVent system Specification) formalism. The intrusion detection agent uses the ES (Expert System). The intrusion detection system detects the intrusions using the blackboard and the firewall responses these detection information.

이동 에이전트는 자율적으로 수행이 가능한 능동적인 객체이지만 이동 에이전트 서버에 의해서 수행되기 때문에 서버에 대한 보안상 취약점을 가진다. 이와 관련하여 다양한 연구가 진행되었고 일정한 조건 안에서 안전한 방법들이 제안되었다. 그 중에는 여러 서버를 중첩하지 않고 순회하는 조건에서 안전한 수행 결과를 보장하는 방법이 있다 [10,11]. 이 방법은 신뢰 서버를 기점으로 에이전트가 자유롭게 순회를 하고 그 결과를 체인화하여 저장하는 방법이다. 본 논문에서 중첩된 순회를 가능하게 하며, 중요한 의사 결정을 안전하게 수행할 수 있는 이동 에이전트를 위한 베이스캠프를 제안한다.
