Sniffers possess huge potential in monitoring and validating internet traffic. They are essential for efficient working of computer networks in any organization. Sniffer helps to monitor a network as well as capture the passwords used in telnet, login and ftp connections. It examines and sniffs packet travelling through a network without altering them. Sniffer decodes the captured packets and allows network administrators to understand, analyze and recover useful information from packet content. Besides being a boon for organization, hackers also use sniffers for indulging into malicious acts of hacking other users’ account and systems. This paper focuses on the development and implementation of a new sniffer named as Sniflyzer and briefly explores the protocols used in analyzing a packet. Implementation results illustrate that Sniflyzer creates an encrypted database of packet and the front end displays the front end displays the appropriate information as desired by the user.
