Network Sniffing

Network sniffing is the process of monitoring and capturing network traffic. It is a powerful tool for network administrators, security analysts, and anyone else who needs to troubleshoot network problems or gather information about network activity.

How Does Network Sniffing Work?

Network sniffing works by using a network interface card (NIC) to capture packets of data that are traveling over a network. The NIC can be configured to capture all traffic, or it can be filtered to only capture specific types of traffic, such as traffic from a particular IP address or port.

Once the packets have been captured, they can be analyzed using a variety of tools. These tools can be used to identify the source and destination of the packets, the type of traffic, and the contents of the packets.
