Since Electronic Security System is introduced in Korea in 1981 by foreign technology, Security market has been increasing considerably during short period, and It performs it's security roles well in place of security guards. As electronic and communication technology is highly developed, Electronic Security System and security market structure is changing naturally. Especially high-tech mobile communication technology will change the method of Electronic Security business. Also the pattens of residence and life style, such as the trend toward nuclear family and single life could effect security market. In recent year, new business models that apply the mobile phone and internet is appeared. Although Electronic Security System is changed by the changes of technology, It is very difficult to change the basic elements, such as sensing, alarm signal transfering, and response. The rate of increase of Electronic Security market is expected to matain it's increase pace for the time being. But the development of new system for new protectes such as childeren, old person, vehicle rather than immovable facility is necessary to prepare for the continuous competition.

The rapid spread of smart phone in recent years changes not only personal life but also work environment of organizations. Moreover, smart phone provoke service combination between industries and transit the digital paradigm in our society because of the character that anyone can develop or use the application of smart phone. Under these circumstances, the government hastens the construction of mobile-government in order to improve national services and communication with people. However, since security threats on smart phone become more critical recently, we should hurry the counter measures against mobile threats or we will face obstacles to the activation of mobile-government. On this article, we suggest the methods of information security and the Mobile-government Information Security Management System(M-ISMS) on the smart phone use environment for building up the secure and convenient mobile system in the national institution.

Network industry is complex combined with various fields of industry, such as communication, broadcast, construction, and home appliances. Moreover, it's fairly lucrative since the growth industry makes lots of added values, interacting with the others. The network industry, usually called 'Ubiquitous', connects some home appliances and makes an integrated system that you can use them with whenever and wherever. A demand for network security, however, has skyrocketed due to the relatively low safety. It's been expected that the market of home security is going to be grown up nearly 30 percent every year. Recently, analog surveilance cameras have been replaced with digital ones, and they will be providing stronger security services taking advantage of mutual interaction with related industies. In this paper, a mobile monitoring system for home security is proposed, which makes it possible to supervise all home appliances wherever you're, using the conventional wired/wireless network infra.

Currently, there are many subscriber access networks: PSTN, ADSL, Cellular Network, IMT200 and so on. To these service providers that provide above network service, it is important that they authenticate and authorize legal subscribers and account for their usage. At present, There exist the several protocols that Support AAA(Authentication, Authorization and Accounting) service : RADIUS, Diameter, TACACS+. Nowadays, RADIUS has used for AAA service widely. It has been extended to support other access network environment. So, we extend RADIUS to support environment of Mobile IPv6. Mobile IPv6 uses IPsec as a security mechanism, basically. But, IPsec is a heavy security technology for small, portable, mobile device. Especially, it is serious at IKE, the subset of IPsec. IKE is a key distribution protocol that distributes the key to the endpoints of IPsec. In t:lis paper, we extend RADIUS to support environment of Mobile IPv6 and simplify the IKE phase of IPsec by AAA system distributing the keys by using its security communication channel. Namely, we propose the key distribution method for IPsec SA establishment between mobile node and home agent. The suggested method was anticipated to be effective at low-power, low computing deyice. Finally, end users feel the faster authentication.

The Sambodana project is a mobile communication security system development project using Hardening Android. The initial idea for this project is that information leakage occurs outside of a communications application with end-to-end cryptographic security. Android hardening prevents unwanted applications and bloatware from being installed, such as unavailable Google Play Store or install restrictions.

Due to rapid development of mobile device technologies, the mobile banking through Internet has become a major service of banking information systems as a security-critical information systems. Recently, lots of mobile banking information systems which handle personal and transaction information have been exposed to security threats in vulnerable security control and management processes, mainly software systems. Therefore, in this paper, we propose a process model for software security improvements in mobile banking information system by application of fault tree analysis(FTA) and failure modes and effects analysis(FMEA) on the most important activities such as 'user authentication' and 'access control' and 'virus detection and control' processes which security control and management of mobile banking information systems are very weak.

The popularity and adoption of smart-phones has greatly stimulated the spread of mobile malware, especially on the popular platforms such as Android. The fluidity of application markets complicate smart-phone security. There is a pressing need to develop effective solutions. Although recent efforts have shed light on particular security issues, there remains little insight into broader security characteristics of smart-phone application. Now, the analytical methods used mainly are the reverse engineering-based analysis and the sandbox-based analysis. Such methods are can be analyzed in detail. but, they take a lot of time and have a one-time payout. In this study, we develop a system to monitor that mobile application permissions at application update. We had to overcome a one-time analysis. This study is a service-based malware analysis, It will be based will be based on the mobile security study.

Recently. smartphones have been popularized rapidly and now located deep in our daily life, providing a variety of services from banking, SNS (Social Network Service), and entertainment to smart-work mobile office through apps. Such smartphone apps can be easily downloaded from what is known as app store which, however, bears many security issues as software developers can just as easily upload to it. Military apps will be exposed to a myriad of security threats if distributed through internet-basis commercial app store. In order to mitigate such security concerns, this paper suggests a security guidelines for establishing a military-excusive app store and security verification system which prevent the security hazards that can occur during the process of development and distribution of military-use mobile apps.
