A Packet Sniffer CSE Seminar Download is a network analyzer that plugs to computer networks and eavesdrops on the network connection. It is a wiretap device. Sniffing refers to capture the data and information over the network traffic. A sniffer can catch all packet traffic on network block.
With the help of “sniffing” program, a programmer can listen in on computer conversations. Therefore, computer conversations consist of apparently random binary data and the wiretap programs of the network also has a feature known as “protocol analysis” that allows them to “decode” the network traffic and make sense of it.
It was the first device that enables a programmer to sit at their desks and takes the pulse of the wide range of the network. The original sniffers read the message headers of data packets on the network, giving administrators the details about the addresses of senders and receivers, file sizes and other low-level information about those packets, in addition to verifying transmission.
Today, packet sniffer has two broad varieties: the first is a standalone product into a computer that carries to sites and plugs into the network to gather diagnostic data and the second is part of a larger package network hardware and software to keep tabs on LANs, WANs and Web services.
Packet sniffers monitor and capture packet traffic over the wide network, usually an Ethernet and are placed surreptitiously on drives.
They help networks in keeping humming. It can also be used by hackers to hack user names and passwords from data packets that are traveled across public or private WANs. It is a two-fold process: encryption and compartmentalization.
Encrypted communications prevent the capture of passwords if a sniffer attack is underway. Also, if a proficient sniffer can see what kind of data and information can actually be extracted from any particular network traffic.
