SNIFFER Meaning and
Definition
-
A "sniffer" is a noun that typically refers to a device or program that is used for capturing and analyzing network traffic. It is designed to intercept and examine the data packets that are transmitted over a computer network. The primary purpose of a sniffer is to monitor the network and collect information about the data being transmitted.
Sniffers are commonly used by network administrators, security professionals, and hackers to diagnose network issues, identify network vulnerabilities, and analyze the behavior of network applications. By capturing packets, a sniffer can reveal details such as the source and destination IP addresses, protocols in use, and the content of the transmitted messages.
Sniffers can be either hardware-based devices or software programs. Hardware-based sniffers are typically placed in between network devices like routers or switches, allowing them to passively listen to and capture network traffic. Software-based sniffers, on the other hand, are programs that can be installed on a computer system and utilize the network interface to examine the network traffic.
It is important to note that while sniffers have legitimate uses for monitoring and troubleshooting network issues, they can also be misused for malicious activities. In the wrong hands, sniffers can be employed to capture sensitive information, passwords, or other confidential data as they intercept all network traffic on a given network segment. Therefore, the usage of sniffers should be regulated and strictly controlled to maintain network security and privacy.
