The choice of high-grade complete network security equipment is every successful enterprise essential networking facilities, but in fact there are threats in more networks coming from within the enterprise, so it's not enough to just protect the boundaries of network formation, and building an integrated, multi-level security architecture can provide more thorough and practical protection, To improve the internal security awareness of enterprises is to solve the enterprise network security.

The basics of Cisco PIX Firewalls
Cisco PIX Firewalls can protect various networks. There are pix firewalls for small home networks, as well as PIX firewalls for large parks or corporate networks. In the example of this article, we will set up a PIX type 501 firewall.
1.ASA Security Level
By default, the Cisco PIX firewall applies security levels to each interface. The more secure the network segment, the higher the full level. Security levels range from 0~100, by default, security level 0 is adapted to E0, and its default name is external (outside), and security level 100 is suitable for E1. And its default name is inside. Use the name if to configure any additional interfaces, security levels in the 1~ Between 99

PIX win is the direct3d file attached to the DirectX SDK.ProgramThe debugging and analysis tool is used for d3d applications. If the developer of d3d needs to collect and analyze the call and execution information of the application to the 3dapi, this tool is a good choice. For example, you need to know whether the background rendering target, depth buffer, and template buffer are correctly rendered during a rendering process, alternatively, you can u

The Cisco PIX Firewall installation process is as follows:
1. The PIX will be placed to the rack, after the detection of the power system connected to the power supply, and power on the host.
2. Connect the console port to the PC's serial port and run the HyperTerminal program from the console port into the PIX system; the system prompts pixfirewall>.

To solve this problem, enabling Java filtering can prevent internal systems from downloading Java applets. When port 80 (HTTP) is allowed, Java applets may be downloaded. Some Java applets may contain hidden code, which may damage data in the internal network. The
