According to the development of information processing technology and mobile communication technology, the utilization of mobile banking systems is drastically increasing in banking system. In the foreseeable future, it is expected to increase rapidly the demands of mobile banking in bank systems with the prevalence of smart devices and technologies. However, the keeping 'security' is very important in banking systems that handles personal information and financial assets. But it is very difficult to improve the security of banking systems only with the vulnerabilities and faults analysis methods of information security. Hence, in this paper, we accomplish the analysis of security risk factor and security vulnerability that occur in mobile banking system. With analyzed results, we propose the information security control and management processes for assessing and improving security based on the mechanisms which composes mobile banking system.

Recently, with the rapid spread of mobile terminals such as smartphones and tablet PCs, social demand for mobile information security is increasing as new security issues that are difficult to predict as well as service evolution and lifestyle changes are raised. Smart terminals include smartphones, smart pads, chromebooks, laptops, etc. that provide various functions such as phone calls, text messages, Internet browsing, social media apps, games, and education. Along with the explosive spread of these smart terminals, they are naturally being used in our daily life and educational environment. In the mobile environment, behind the convenience of portability, there are more various security threats and vulnerabilities than in the general PC environment, and threats such as device loss, information leakage, and malicious codes exist, so it is necessary to take fundamental security measures at a higher level. In this study, we suggest ways to improve security by identifying trends in mobile smart information security and effectively responding to security threats to the mobile environment. In addition, it presents implications for various measures for effective class utilization along with correct security management methods and security measures related to the supply of smart devices that the Office of Education is promoting for schools at each level.

CC (Common Criteria) requires collecting vulnerability information and analyzing them by using penetration testing for evaluating IT security products. Under the time limited circumstance, developers cannot help but apply vulnerability analysis at random to the products. Without the systematic vulnerability analysis, it is inevitable to get the diverse vulnerability analysis results depending on competence in vulnerability analysis of developers. It causes that the security quality of the products are different despite of the same level of security assurance. It is even worse for the other IT products that are not obliged to get the CC evaluation to be applied the vulnerability analysis. This study describes not only how to apply vulnerability taxonomy to IT security vulnerability but also how to manage security quality of IT security products practically.

Although more than 99% of all Korean companies are small and medium-sized enterprises (SMEs), which accounts for a large part of the national economy, they are having difficulties in securing information protection capabilities due to problems such as budget and manpower. On the other hand, as 97% of cyber incidents are concentrated in SMEs, it is urgent to strengthen the information protection management and response capabilities of SMEs. Although the government is promoting company-wide information security consulting for SMEs, the need for supplementing it's procedures and consulting items is being raised. Based on the results of information security consulting supported by the government in 2020, this study attempted to derive improvement plans by interviewing SME workers, information security consultants, and system operators. Through the research results, it is expected to create a basis for SMEs to autonomously check the information security management system and contribute to the reference of related policies.

This is an extended paper, focusing on the cost management for the organizations dealing with the crucial issues of security systems. Information Technology (IT) is an important and irreplaceable need of society and all working sector's success depends on IT to a greater extent; therefore maintaining security features is one of the most important aspects of IT. When security in the IT sector is discussed, Patch Management (P.Mgnt) has to be taken under account. P. Mgnt includes many concerns and areas to be described for IT security such as methods and problems in updating patch, methods of reducing security risks with P.Mgnt, methods of achieving economies of scale by controlling the operational costs and taking decisions in investing as and when necessary. This paper presents a general definition of Patch management, its benefits and management of working cost through theoretical models, also the paper gives methods of feeding techniques for microstrip patch antenna MPA, showing the contracting and non contracting methods.

In the recent IT industry, security has established itself as the factor to be considered the most in the software development. It goes without saying that security is the critical factor for the development of information security products. In the evaluation of the information security products, the security is assured by the security architecture requirement (ADV_ARC). However, the Absence of the systematic software security architecture process makes it difficult to guarantee the security quality consistently even though they are evaluated based on common criteria. In this paper, we propose a way to ensure a consistent security quality applying the software security framework in BSIMM.

Social networking service (SNS) is a service that allows people to share information, manage relationships with others, and express themselves on the Internet. The number of SNS users have increased explosively with the growth of mobile devices such as smartphones. As the influence of SNS has grown extensively, potential threats to privacy have also become pervasive. The purpose of this study is to empirically examine the main factors that affect users' intentions to use security functions provided by their SNS. The main theories for this study include the rational choice theory and the theory of planned behavior. This study has identified the factors that affect intention to use security functions. In addition, security function awareness and information security awareness are found to be important antecedents for intention to use security functions. The results of this study implies that when SNS providers develop security policies, they should consider the ways to improve users information security awareness and security function awareness simultaneously.

Recently, Financial companies implement DLP(Data Leaks Prevention) security products and enforce internal controls to prevent customer information leaks. Accidental data leaks in financial business increase more and more because internal controls are insufficient. Security officials and IT operation staffs struggle to plan countermeasures to respond to all kinds of accidental data leaks. It is difficult to prevent data leaks and to control information flow in business without research applications that handle business and privacy information. Therefore this paper describes business and privacy information flow on applications and how to plan and deploy security container based OS-level and Hypervisor virtualization technology to enforce internal controls for applications. After building security container, it was verified to implement internal controls and to prevent customer information leaks. With security policies additional security functions was implemented in security container and With recycling security container costs and time of response to security vulnerabilities was reduced.

Information security to use information technology(IT) in safety and reliability environment is becoming of great importance. In advanced countries including United States and United Kingdom are consistently expanding budget for information security. Korea also has been a growing interest in information security and Korea government announced plan to develop information security into next-generation growth engine. However, information security budget has increased slightly in recent years, so many national institutions and state governments have budget shortfall to perform information security work. Moreover budget items do not include generic contents about information security and there are confined to some security SW, HW and services. It is necessary to expand information security budget for enhancement national capabilities of information security. In this paper, we analyze the IT and information security budget situation for Korea and United States and propose effective budget expansion and improvement approaches for Korea.
