A passive attack refers to a type of network security attack where the attacker monitors or intercepts data being transmitted over a network without altering or affecting the communication or data flow. Unlike active attacks, where an attacker tries to disrupt or manipulate data, passive attacks aim to gather information without being detected. Key characteristics of passive attacks include: 1. **Eavesdropping**: The attacker listens to or captures data packets as they travel across the network. This could involve using tools to sniff network traffic.
