Can someone give me the definition in simple terms when it comes to computers what is meant by "easedropping"? I know it means listening in on someone else's conversation.
A program and/or device that monitors data traveling over a network. Sniffers can be used both for legitimate network management functions and for stealing information off a network. Unauthorized sniffers can be extremely dangerous to a network's security because they are virtually impossible to detect and can be inserted almost anywhere. This makes them a favorite weapon in the hacker's arsenal.
On TCP/IP networks, where they sniff packets, they're often called packet sniffers.
