네트워크 트래픽 모니터링에 있어서 트래픽을 사용하는 목적을 알아내는 것은 서비스 품질, 방화벽의 동작, 보안 측면에 있어서 중요한 이슈가 되고 있다. 트래픽을 사용하는 목적을 알게 되면 이를 방화벽에서 거부하거나 허용할 수 있고 이는 서비스 품질, 보안적 측면에서 효과적인 운용이 가능해진다. 하지만 수많은 어플리케이션은 보안이나 서비스 측면에서 트래픽을 암호화시키고 있어 효과적인 트래픽 모니터링이 어렵다. 본 논문에서는 암호화된 트래픽을 사용하는 SSH(Secure Shell) 프로토콜을 분석하고 SSH 터널링, SFTP(SSH File Transfer Protocol)와 일반 SSH 트래픽의 차이점을 분석하고 식별할 수 있는 방법을 제시하고 실험을 통해 검증했다.

현재 많은 중앙행정기관 및 지방자치단체, 공공 민간기관들이 사이버 침해사고 대응을 위해 보안관제서비스를 운영하고 있다. 과거와는 달리 서비스 도입보다는 효율적인 운영을 위해 노력하고 있다. 때문에 많은 정책과 방향, 지침들을 수립하고 안정적으로 운영되길 원한다. 하지만 보안관제는 사람이 운영하는 업무이기 때문에 개개인의 능력에 따라 많은 차이를 보이게 된다. 이에 따라 본 논문에서는 보안관제 기술과 방법에 대해 살펴본 후 인적역량에 대한 평가 방법과 예시를 통해 기관의 보안관제 업무 시 인적 관리에 효율적인 운영 방안 및 향후 발전 방향에 대해 모색해 보고자 한다.

According to the current record of Private Security in Korea, more than 110,231 private security guards and around 2,213 security guard associations are engaged in the private security industries. However, there is no a professional license for the private security. In order to be provided a high quality service from private security industries, the security guard should be required his/her professional qualification which can be upgraded by establishing a professional license system. For introducing the license system the government and security guard associations need to support the suitable training program including curriculum and method, and all associations related to the private security have to require people involved in any kinds of private security matters to complete obligatorily some educational training programs. And also, to complete a college should be the minimum requirement.

Consumers who purchase products from foreign countries and deliver them back to Korea are increasing. According to the Korea Fashion & Textile News (2015), overseas direct shopping reported 39% increase compared to 2013. Furthermore, clothes accounted for 19% of product category. Therefore, the service quality of overseas purchase sites is becoming more important, but studies have been limited. this research focuses on investigating the effects of consumers' shopping orientation on service quality and the effects of service quality on trust, satisfaction, and consumer loyalty. The survey was administered to consumers who had experiences in purchasing through overseas direct purchase websites. The results showed that the perception of service quality differed depending on the respondent's shopping orientation. Among the four shopping orientation groups(shopping confidence, shopping enjoyment, trend pursuit, and shopping follower groups), the shopping confidence group showed the highest mean for all service quality factors. All the groups showed the highest scores on product and trust among the factors of service quality. Next, the results revealed that service quality positively influenced consumers' trust on websites that provide overseas direct purchase services, which further improved customer loyalty. Therefore, the study gives managerial suggestions to online retailers that provide oversea shopping service. They need to provide higher site efficiency, security, product reliability, and responsiveness to cultivate international customers' trust and satisfaction. In particular, it will be important for them to offer accurate, reliable product information and various languages for overseas customers.

Internet/Intranet has been continuously enhanced by new emerging IP technologies such as differentiate service(DiffServ), IPSec(IP Security) and MPLS(Multi-protocol Label Switching) traffic engineering. According to the increased demands of various real-time multimedia services, ISP(Internet Service Provider) should provide enhanced end-to-end QoS(quality of service) and security features. Therefore, Internet and Intranet need the management functionality of sophisticated traffic engineering functions. In this paper, we design and implement the performance management functionality for the guaranteed end-to-end QoS provisioning on MPLS-based VPLS(Virtual Private LAN Service). We propose VPLS OAM(Operation, Administration and Maintenance) for efficient performance management. We focus on a scheme of QoS management and measurement of QoS parameters(such as delay, jitter, loss, etc.) using VPLS OAM functions. The proposed performance management system also supports performance tuning to enhance the provided QoS by re-adjusting the bandwidth of LSPs for VPLS. We present the experimental results of performance monitoring and analysis using a network simulator.
