This research investigates the impacts of information security (IS) culture and management leadership styles on employee's security behaviors (IS policies compliance, IS participation) in financial institutions. This study use the survey data collected from 236 employees of financial institutions. This research shows that IS culture has a positive effect on both behavioral intentions to comply with IS policies and the intentions to actively participate in information security activities. Transactional leadership has a positive impact on the IS policies compliance intentions and to participate in information security activities. In contrast, transformational leadership has a positive impact on the intentions to participate in information security activities, but not on the IS policies compliance intentions.

Current computer viruses are one of the most serious problems in information age due to their potential demage and impact on use of information systems. To make the problem worse, virus development technology has been advanced rapidly, and use of network systems has expanded widely. Therefore computer viruses are much more complex and use of anti-virus software(AV S/W) is not enough to prrevent virus incidents. It implies that computer viruses as well as other information security matters are not solely a technical problem but also a managerial one. This study emphasized on computer virus controls from managerial perspective of information security and investigated factors influencing the effectiveness of computer virus controls. Organization's comprehensive security policies provide guidelines on how organization or individual can protect themselves from computer viruses. Especially, user's education has positive impact on user's security related characteristics. Based on the analysis of research model using structural equation modeling technique, security policies were influencing security controls and improving user's computer viruses related awareness. Also security controls had positive impact on security effectiveness. However, no significant relationship was found between user's security related characteristics and security effectiveness.

The focus of this paper is comparing relative effects of government policies for upbringing information security industry from the dynamic point of view. For the purpose of simplicity, these policies are classified into three groups, and then the relative effectiveness of these policy groups is examined using System Dynamics. The three policy groups are composed of technology development policies (TDP), human resource development policies (HDP), and direct supporting policies for overseas expansion (DSP). From the result of the analysis, DSP appears to be the most effective and HDP is the second-best group. By the way, for successful carrying into effect of DSP, marketing manpower should be strengthen. However, current HDP has been focusing on the bringing up technical experts. Therefore, overseas marketing manpower should be reared as well as technicians. Also, the existing infrastructure for overseas expansion for other industries should be shared for DSP of information security industry, because this is essential for success of DSP in terms of timing and costing. Finally, in spite of its low effect, TDP should be maintained continuously. The importance of information security technology is increasing and some countries have already considered these technologies as a core of future national defense. Therefore, we should acquire the competitiveness for a few technologies through continuous development of selected technologies at least.

Information securiry is considered important due to the side effect generated from the expansion of information system and rapid increase of the use of internet. Nevertheless, we are getting unconscious of the importance of information security. The purpose of this research is to empirically analyze that the effects of security policies, security awareness and individual characteristics on password security effectiveness. Based on the analysis of research model using structural equation modeling technique, security policies were influencing individual characteristics and improving user's security awareness. Also individual characteristics and security awareness had positive impact on security effectiveness.

This paper addresses the problem of protecting security policies in security mechanisms, such as the detection policy of an Intrusion Detection System. Unauthorized disclosure of such information might reveal the fundamental principles and methods for the protection of the whole network. In order to avoid this risk, we suggest two schemes for protecting security policies in Snort using the symmetric cryptosystem, Triple-DES.

Enterprise security management system proposed to properly manage heterogeneous security products is the security management infrastructure designed to avoid needless duplications of management tasks and inter-operate those security products effectively. In this paper, we propose the model of generalized security policies. It is designed to help security management build invulnerable security policies that can unify various existing management infrastructures of security policies. Its goal is not only to improve security strength and increase the management efficiency and convenience but also to make it possible to include different security management infrastructures while building security policies. In the generalization process of security policies. we first diagnose the security status of monitored networks by analyzing security goals, requirements, and security-related information that security agents collect. Next, we decide the security mechanisms and objects for security policies, and then evaluate the properness of them on the basis of security goals, requirements and a policy list. With the generalization process, it is possible to integrate heterogeneous security policies and guarantee the integrity of them by avoiding conflicts or duplications among security policies. And further, it provides convenience to manage many security products existing in large networks.

Despite the limitations of existing security policies due to technological development, companies are unable to actively respond to changes by maintaining a closed security policy. This study classified information security policy into three types: regulatory type policy, advisory type policy, and informative type policy. For each classified policy type, the effect on the information security policy compliance behavior of organizational members was investigated by applying the extended theory of planned behavior, and the moderating effect of information security stress was investigated. SmartPLS 2.0 and SPSS 21.0, which are structural equation modeling techniques, were used to analyze the relationship affecting each factor. As a result of the study, regulatory type, advisory type, and informative type security policies affected organizational members' information security policy compliance behavior, and security stress had an effect on information security compliance attitudes and subjective norms on information security, which are prerequisites for planned behavior theory. gave. This study suggests that various types of corporate information security policies can be applied and that security stress can affect information security behaviors of members.

In this paper, we propose adaptive convergence security policies and management technologies to improve security assurance in the home networking environment. Many security issues may arise in the home networking environment. Examples of such security issues include the user privacy, the service security, the integrated networking security, the middleware security and the device failure. All these security issues, however, should be fulfilled in phase due to many difficulties including deployment cost and technical complexity. For instance, fundamental security requirements such as authentication, access control and prevention of crime and disaster should be addressed first. Then, supplementary security policies and diverse security management technologies should be fulfilled. In this paper, we classify these requirements into three categories, a service authentication, a user authentication and a device authentication, and propose security policies and management technologies for each requirement. Since the home gateway is responsible for interconnection of many home devices and external network access, a variety of context information could be collected from such devices.

A campus network nowadays adapts the security policies in detail and even in variety, along with firewall based access control. Nevertheless, security threats, such as information hacking, intrusion and DoS, are not decreasing yet. This paper proposes an enabling method of discriminative security policies to enforce an adaptive security for security objects on basis of the security elements. The security level of a security devices is decided based on the mapping between the users and the objects. The proposed security policies could improve the security effect in terms of investment in creative campus environment, and aim to provide fast and stable services to users.
