Based On The Research Of Linux Netfilter Under The Framework Of Intelligent Firewall

In recent years, mobile communication technology has developed rapidly, and the mobile network intrusion detection is accompanying me, an important trend has been written in modern communication technologies. Many scholars believe that, by 2015, the mobile terminal of 3S will come standard with embedded video, a large number of audio program and hardware devices, the mobile Internet and intrusion detection chip and market means that business opportunities and great prospect, will bring high economic benefits. In addition, a variety of products to personal media players as the representative of the will become the development direction of personal network intrusion detection digital consumer products.Linux is a complex task can be used to deal with the operating system, and is an open source embedded operating system. Meanwhile the research and application of its own core research and development to increase capacity, reduce dependence on foreign-related software. Usually embedded Linux kernel, root file system, Bootloader, development tool chain, the main system settings, applications, and services nfs and tftp composition Linux software development environment. In these components, the DM320 how to build a suitable platform and embedded Linux kernel Bootloader been achieved in the design of intelligent firewall.NETFILTER use this tool to achieve security and stability on the Linux server, a powerful firewall. It is also widely used at present enterprises and universities a more advanced technology. This paper presents an in NETFILTER(, intelligent firewall) method for embedded Linux applications on the system; re-examined as well as customized embedded Linux operating system, and the second based on the Linux operating system successfully transplanted to NETFILTER equipment, addition addition, this method can also be gradually extended structural design of other consumer electronics products on.Embedded Linux software development environment includes the following parts: Based on Bootloader, the embedded Linux kernel, root file system, development tool chain, the main applications, NFS and TFTP service settings. How to construct the DM320 platform of Bootloader and embedded Linux kernel was implemented in the design of the intelligent firewall.
