Network sniffing involves using sniffer tools that enable the real-time monitoring and analysis of data packets flowing over computer networks. These network sniffers can be detected by using various techniques such as:

• Ping Method: Identifies if a system on the network is running in promiscuous mode
• DNS Method: Identifies sniffers in the network by analyzing the increase in network traffic
• ARP Method: Sends a non-broadcast ARP to all nodes in the network; a node on the network running in promiscuous mode will cache the local ARP address
