The interest in SLA in accordance with the development of IT outsourcing has increased due to the rapid development of information systems. Moreover, an awareness and necessity for the Information System Operating Audit has increased while an effective IT service management operations for information systems is needed desperately. However, information system operations and maintenance instructions of the National Information Society Agency operates due to the current information system operation, but the experience and the interpretation of the auditor determine the decision in the field. This paper introduces an operating audit model for the efficient management. This model is derived from the Korea Information Society Agency's operating instructions of the Information Systems Audit and their inspection services. The audit checklists were derived from the areas of service planning, service delivery, service support, and service management. Consequently, the operating audit model was proposed, and the suitability of this model was verified by experts' opinions on the survey.

In recent years, major security data such as research data and confidential documents have been leaked to the outside due to the carelessness of the companies and research institutes performing IT related services such as information technology projects and research and development of financial institutions, companies and public institutions is. Leakage cases are caused by leakage of personal information due to lack of security management of information system maintenance companies, such as unauthorized leakage or storage of related materials in outsourcing service process. In this paper, we analyzed the types and management status of service business through the environmental survey of corporate informatization business and analyzed the problems in development and maintenance using external service companies. Furthermore, in this paper, we provide an information system service that focuses on the business activities based on the items considered, and at the same time, it provides the informatization service for companies that can prevent infiltration of viruses and hacking from the outside. This paper presents a methodology for enhancing security for the system construction.

정보시스템 아웃소싱(outsourcing)의 적용 범위와 그 규모가 증대함에 따라, 아웃 소싱은 정보시스템의 관리에서 근본적인 이슈로 등장하게 되었다. 정보시스템 아웃소싱의 중요성이 인식되었으나, 그에 대한 실증적 연구는 매우 미흡한 설정이다. 본 연구의 주요 목적은 정보시스템 아웃소싱에 있어 고객회사(client firm)와 서비스 제공업자(vendor)간의 관계의 성공 및 실패에 영향을 미치는 요인을 조사하는 것이다. 본 연구의 연구 모델은 관 계적거래이론(relational exchange theory), 커뮤니케이션 행동(communication behavior), 거래비용분석(transaction cost analysis) 등의 조직간관계(interorganizational relationship) 이론에 기반을 두고 작성되었다. 미국의 207개 회사의 정보시스템 아웃소싱 설문조사에 의 하여 다음과 같은 연구결과가 도출되었다. (1) 서비스 제공업자의 능력(vendor capability), 관계결속성(solidarity), 관계지속성(continuity expectation), 유연성(flexibility), 서비스업자의 활동에 대한 모니터링(monitoring of the vendor), 참여도(participation) 등이 아웃소싱 관 계의 성공과 양의 상관관계를 가지고 있으며, (2) 역할연합도(role integrity), 자산특이성 (asset specificity) 등은 아웃소싱 관계의 성공과 음의 관계를 가지고 있는 것으로 나타났 다. 이 결과에 의하면, 비관계적 거래(discrete exchange) 보다는, 관계적 거래(relational exchange)에 기반을 두어 아웃소싱 관계를 운영하는 것이 아웃소싱의 성공적인 구현을 필 수적으로 보여진다. 이 연구 결과를 기초로 하여 아웃소싱 대상 업무의 선택, 서비스 제공 업자의 선택, 그리고 아웃소싱 관계의 지속적인 관리를 위한 지침을 제시하였다.

The purpose of IT Service Level Management(SLM) has recently shifted from being a simple financial contract(SLA contract itself) towards a system(SLA management system) for the management of the customer's expectations and the provider's service. The aim of this paper is to introduce and present the systematic SLM using statistical method. We discuss the service level according to two points of view: statistical method and service level management. First, we go into more detail on the objective service level using statistical method. Second, we give an overview of total service level assessment method. The proposed framework enables to measure total service level as IT outsourcing performance quantitatively from the aspect of business strategy.

This study offers a $3{\times}2$ matrix on the development method pursuant to the level of readiness and necessity for IS of SMEs, and the Delphi method survey through the assistance of a panel of IT experts was employed. Upon analyzing the results, in all rounds, the 1st quadrant and 2nd quadrant resulted in a preference for leasing methods (ASP/SaaS) and the other quadrants resulted in a preference for outsourcing. Quadrants closer to the 1st quadrant showed a preference for leasing methods (ASP/SaaS) and quadrants closer to the 6th quadrant showed a preference for outsourcing. In the case of the IS implementation for the entire company, all three levels of readiness resulted in a preference for outsourcing. The point in which the implementation method changed depending on the level of readiness was when unit systems were implemented, and among the implementation methods, in-house development showed the lowest results.

This paper's object is to study the Advanced Foreign's Third Party Logistics Trend & View at Global Logistics Times. So, I analysed the Advanced Foreign U.S. & EU and the results are as follows: First, a growth in the number of outsourcing relationships has contributed to the development of more flexible organizations, based on core competencies and mutually beneficial longer-term relationships. So, the development of logistics relationships has brought mixed results. Across many industries, logistics outsourcing is a rapidly expanding source of cost savings, competitive advantage, and customer service improvements. Thus, it appears that Third Party Logistics(TPL) concepts could be useful in meeting the goals of the 1ogistics function. Second, the field of logistics and supply chain management is becoming strategically important. At the same time, it is becoming increasingly complex because of the rapid advances in management methods, e-commerce, technology, and enabling information systems. However, Third Party Logistics provider, many a times, lack broad set of skills, integrating technologies, strategies and global reach. So, Fourth Party Logistics(4PL) is the next significant evolution in supply chain outsourcing. 4PL delivers a comprehensive supply chain solution, and delivers value through the ability to impact the entire supply chain. The 4PL industry is likely to grow as more companies use e-commerce at Global Logistics Times.

Internet attack incidents have steadily increased along with the increase in Internet users. To protect systems and networks from these attacks, advanced security systems have been developed. Now that these security systems are operating, their successful management is more important than the purchase and establishment of new information security systems. The acquisition of good systems is ineffective and financially wasteful unless they are managed properly. Adequate management policy has recently become the focus of users. In other words, for companies and educational institutions with their domains, capital expenses are enormous to bear, and good security staffs are difficult to find, for which reasons outsourcing vendors or Managed Security Service Providers (MSSPs) that manage and operate the information security systems of certain domains become very appealing. Today, customers expect ISPs to perform MSSP services that used to be carried out by the security companies. This document presents the role and necessity of ISPs as MSSPs.
