shard Tap or Hub between the vswitch and the vro or firewall to complete data capture. When analyzing a department or a network segment at a specified point, the network topology is often very complex. During network analysis, we do not need to analyze the entire network, y

following information:The first display is the network card name, common are: ens33 eth0 eth1 em1 em2 p2p2 p3p3, etc.If the network card does not start, the displayed information is usually no IP address. Start the NIC to use ifconfig up.Ifup: Start the specified NIC on the systemIfdown: Stop the network adapter specified on the systemThe above two commands are

image Function Some simple vswitches may not have the image function and cannot monitor and analyze the network through port images. In this case, you can concatenate a shard (Tap) or Hub (Hub) between the vswitch and the router (or firewall) to complete data capture. The installation diagram is as follows. Analyze a department or CIDR block at a specified point In actual situations, the

Introduction to the use and setting of the network security tool software BlackICE)BlackICE won the PC Magazine technical excellence award in year 99. Experts commented on it: "For home users without firewalls, BlackICE is an indispensable line of defense; for enterprise networks, an additional protection measure is provided. Instead of replacing the firewall, it

, Destination MAC, and L2 Path. With OpenFlow, you can send a set of rules to the vswitch or vro of a "configuration" device. Each device then uses the data according to its type. The vswitch updates its MAC address table to forward frames. The vro adds an access list and the firewall updates its rules. What is a software defined network? When organizations migra

, including Ethernet switches and routers. The intermediate layer is composed of controllers. network devices that forward traffic are used to learn enterprise information such as capacity and requirements. They start and stop traffic. The top layer is some applications that use controllers for security, management, and other special functions. "Suppliers must have one to two layers, or even multiple layers," Forster said ." He pointed out that Big Sw

, the desktop security management (including asset management, knowledge Base management), network performance optimization management, network failure can be connected to the firewall, switch, server and telecommunication line, wiring system, server system timely monitoring and so on the most suitable for government industry.
