In this article, it has been shown that penises devices such as illumination facilities, heating/cooling systems and security equipment can be controlled even outside premises using UPnP (Universal Plug and Play) applicable to the Internet or cellular phone services. To load UPnP protocol into each device, current manufacturers will be required to port flexible OS (Operating System), that is, Windows or Linux to these premises devices. Furthermore, prospective users want to experience a variety of specific functions based on more standardized and stable network. This study aims to provide application by implementing these functions on the Linux system.

As soon as high-performanced smart phones is rapidly emerging in recent, its security problems come to the front. Especially in case of an open platform, it is easy to be a target of virus. Many security solution industries such as Symantec and Ahnlab are developing a mobile security system, but they have not yet a commercial product. We developed the effective security function of Android system based on SELinux to solve this problem, and verified its performance by applying the user applications developed to S3C6410 board.

Many people use Linux and FreeBSD because it is freeware and excellent performance. The open source code is very important feature but it also has some problem which may be attacked by hackers frequently. This paper describes the SecuROS of secure operating system that is best solution to this problem and introduces user and programmer interface for active use of secure operating system. Developed secure operating system is composed of the access control method MAC and ACL and conforms to the POSIX which is universally used.

Linux server offers various kinds of service including web, FTP, and SSH. The users of these kinds of service are trying to hack by making use of it. That’s why some countermeasures are required for the security of the server. In this thesis, each type of service log of multiple Linux server was analyzed, and a solution was developed to monitor and control the multiple Linux server system not based on Linux but based on Windows.

오늘날, 리눅스의 급속한 활용은 상대적으로 해킹사례의 확산으로 이어지고 있다. 이에 리눅스 시스템의 취약점에 대한 패치 파일들이 개발자들에 의해서 빠르게 보급되고 있지만 리눅스 관리자들의 보안에 대한 무관심과 번거로운 업데이트 작업의 기피로 인해 제대로 보안 패치가 이루어지지 않고 있는 것이 현실이다. 본 논문은 이러한 실질적인 문제점들을 해결하고자 지금까지의 번거로운 소프트웨어 패치 작업을 스마트 업데이트 기능을 지닌 LSUS(Linux Smart Update System)을 통해 취약점을 지닌 소프트웨어를 자동으로 패치 함으로써 안전한 시스템을 운영할 수 있도록 하였다.

Middleware enables different networking devices and protocols to inter-operate in ubiquitous home network environments. The UPnP(Universal Plug and Play) middleware, which runs on a PC and is based on the IPv4 protocol, has attracted much interest in the field of home network research since it has versatility The UPnP, however, cannot be easily accessed via the public Internet since the UPnP devices that provide services and the Control Points that control the devices are configured with non-routable local private or Auto IP networks. The critical question is how to access UPnP network via the public Internet. The purpose of this paper is to deal with the non-routability problem in local private and Auto IP networks by improving the conventional Control Point used in UPnP middleware-based home networks. For this purpose, this paper proposes an improved Control Point for accessing and controlling the home network from remote sites via the public Internet, by adding a web server to the conventional Control Point. The improved Control Point is implemented in an embedded GNU/Linux system running on an ARM9 platform. Also this paper implements the security of the home network system based on the UPnP (Universal Plug and Play), adding VPN (Virtual Private Network) router that uses the IPsec to the home network system which is consisted of the ARM9 and the Embedded Linux.

The growth of incidents on the Internet has reflected growth of the internet itself and growth of the computing power. while in previous years, external attacks tended to originate from those interested trend in exploring the Internet for its own sake and testing their skills, there is an increasing trend towards intrusions motivated by financial, political, and military objectives. so, attacks on the nation's computer infrastructures are becoming an increasingly serious problem. Even though the problem is ubiquitious, government agencies are particularly appealing targets and they tend to be more willing to reveal such events than commercial organizations. The threat of damage made necessity of security's recognition, as a result, many researches have been carried out into security of system actively. Intrusion Detection technology is detection of intrusion using audit data differently from using traditional simple filtering and informs manager of it. It has security manager of system deal with the intrusion more quickly. but, cause current environment of Internet manager can't doing response Intrusion alert immediately. That's why IPS needed. IPS can response automatically the intrusion alert. so, manager is more comfortable and can response quickly.
