Network Sniffing (Packet Sniffing)

Network sniffing, also known as packet sniffing or simply sniffing, is a technique used in network management and security to monitor and analyze network traffic. This process involves capturing data packets as they travel across the network, allowing the sniffer to see and record everything being sent over the network, which can include unencrypted passwords, user names, and other sensitive information.

The primary functions of network sniffing include:

Network sniffers can be either hardware or software-based. Software sniffers are programs installed on a computer within the network that have the capability to intercept and log traffic. Hardware sniffers are dedicated devices connected directly to the network with similar capabilities.

While network sniffing is a powerful tool for network management and security analysis, it can also be used for malicious purposes. Unauthorized sniffing can lead to data breaches and is considered illegal in many jurisdictions without proper authorization. To protect against malicious sniffing, organizations often use encryption protocols such as SSL/TLS to secure data transfers over the network.

Proper ethical guidelines and legal compliance are essential when implementing network sniffing to ensure it is used responsibly and effectively for enhancing network security and performance.
