Promiscuous mode is a configuration for a network interface card (NIC) that allows it to pass all network traffic to the CPU for processing, not just the traffic addressed to that NIC. It is commonly used in:

Network sniffing and monitoring

Packet analysis tools like Wireshark

IDS/IPS systems

Module 8: Sniffing
