In today's world, people's computers are interconnected and interconnected. Small to your Home area network (LAN), the largest one is what we call the Internet. When you manage a networked computer, you are managing one of the most critical components. Because most of the developed applications are network-based, the network connects these key points.That's why w

1. Use omnipeek 1) How to intercept data A. Use arp spoofing to make machines in the same network segment think that the attacker is a gateway and send data to the packet capture machine. The attacker routes the data to the real gateway. B. Use a vswitch or vro for internal port forwarding C. Install software on a real vswitch or vro to capture packets, but this may affect the performance. D. Use the dhcp attack software to attack the d
