| Summary: | 碩士 === 南華大學 === 資訊管理學研究所 === 95 === Because of the raising consciousness of information management in recent years, enterprise for high efficiency of reaching but great input information and network to should be used for and used to raise enterprise''s competitiveness. In order to guarantee information security, ample resources, including equipment and human resources, must be put after the application of information and network. However the security problems come from Intranet are more serious than come form Internet because of the congenital advantage the network bandwidth and privilege.
Firewall, a kind of hardware or the software implementations, is the protection mechanism to ensure the valid information transmission of Internet by suitable policy. Information transmission insides firework is usually weak in security management, therefore it is interesting research topic by using simple implementations to managing the information transmission insides firework.
The virtual private network (VPN), a secure data transmission by using the encrypted tunnel technology, can be used in order to get secure communication between enterprises. The information security and privacy can be guaranteed by using VPN in Internet. Transposition transmission can be adopted in VPN, but it is not suitable for the transmission of some sensitive information. Nowadays there are still many problems of security and implementation in many enterprise applications of VPN.
In this research, we focus on the implementation to enhancing the intranet security without changing construct. Our implementation is designed by VPN in embedded systems and is combined the management of firewall. The implementation is an efficient solution to improve the security in intranet.
