Detect Network Sniffing
Jun 12, 2023
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
