Virtualization technology has been widely applied in the area of computer security research that provides a new method for system protection. It has been a hotspot in system security research at present. Virtualization technology brings new risk as well as progress to computer operating system (OS). A multi-level perception security model using virtualization is proposed to deal with the problems of over-simplification of risk models, unreliable assumption of secure virtual machine monitor (VMM) and insufficient integration with virtualization technology in security design. Adopting the enhanced isolation mechanism of address space, the security perception units can be protected from risk environment. Based on parallel perceiving by the secure domain possessing with the same privilege level as VMM, a mechanism is established to ensure the security of VMM. In addition, a special pathway is set up to strengthen the ability of information interaction in the light of making reverse use of the method of covert channel. The evaluation results show that the proposed model is able to obtain the valuable risk information of system while ensuring the integrity of security perception units, and it can effectively identify the abnormal state of target system without significantly increasing the extra overhead.

Computer virus is one of the most common information security problems in the information age. This study investigates the difference of users' perception of security elements between large companies and small-and-medium companies on the subject of computer virus. Based on t-test, no significant difference is found in users' perception on security threat and security risk While users satisfy with the level of security policy, there is a significant difference on the level of security policy recognition between the two sizes of companies. Moreover, there are significant differences on information assets, security vulnerability and security effectiveness, which implies difference in the users' perception on importance of assets, exposure to threats and computer virus prevention efforts between large and small-and-medium companies.

Airport security staff are outsourced workers, whose status is a special security agent under the security service law in Republic of Korea, who are subject to persuing both profitability and public concern at the same time. This paper has chosen the sample of security staff working at Incheon airport. This is because airport security staff is being outsourced, this paper had made an empirical research such areas as the perception of job identity, public service motivation and organizational commitment through job satisfaction. According to statistical research, it was found the perception on job identity by airport security staff had a significant negative effect on both job satisfaction and organizational commitment. The more they have perceived their status as non-permanent status, the less they had job satisfaction and commitment at the same time as a special security agent at airport. Their perception of job identity had a significant effect on such public service motivation factors as 'absorbing public concern' and 'a solicitude'. Lastly, their motivation factors had also significant positive effect on job satisfaction and organizational commitment.

With increasing interest in information security, many studies have been conducted on cultivation and management of information security manpower. The widespread application of information security made the activity of information security professionals more diverse. Therefore, it is essential to analyze the knowledge and skills that are necessary for information security professionals to carry out their job and we also need to take these into considerations for the development and operation of education programs. In this study, for analyzing the perception gaps of information security knowledge and skills level between academia and industry, we have derived 58 knowledge and skills by conducting the literature review and Delphi method and we also conducted a survey of information security knowledge and skills requirements for information security professionals who are now working in industries and educational organizations. As a result, we analyze the perception gaps between two groups of information security professionals and suggest some guidelines for establishing the demand-based curriculum for training information security professionals.

The purpose of this study is to investigate the user's perception of security risk and examine its impact on the usage of Knowledge Management Systems(KMS). The findings of this study are three-fold. First, the overall user's perception of security risk is not high. However, there is a considerably big difference in the perception of security risk among users. This finding means that user's perception of a security risk is not based on the actual security effects but one's individual perception. Another finding is that user's perception of a security risk has a negative impact on the usage of KMS through "trust", which is a mediating variable in our study. This finding corresponds with the existing theory that security risk is oneof the critical sources of trust, and trust is a critical factor of user's acceptance of KMS. Finally, the result of this study reveals that activities devoted to security do not decrease the effectiveness and productivity of KMS. Our long-held cognition that security activity hinders the effectiveness and productivity of an information system is not particularly applied to the KMS.
