What is Packet Sniffing in Networking?
Networking , Technology & Science / July 13, 2018

In computer networks Packets can be defined as a data encapsulation in a structured format. In Internet all traffic travels in the form of packets. The applications such as file downloads, internet surfing, email, all these Internet applications communicate in the form of packets. In internet terminology, packet is a formatted unit of data. Packets are the base of all data sent on the internet. But sometimes it communicated insecurely. Tampering with live packets and in order to alter packets is an easier way of packet based attack deployment. In this context, packet sniffing is commonly known as packet monitoring. Packet sniffers can be a software based application or it can be hardware device which is installed on the network. Sniffers are  basically used with local area networks (LAN) and used to handle data with the current network (i.e. incoming and outgoing traffic). Basics Overview of Packet Sniffing Packet sniffing is the act of capturing packets of data flowing across a computer network. The software or device used to do this is called a packet sniffer. Packet sniffing is to computer networks what wiretapping is to a telephone network.  Packet sniffing has legitimate uses to monitor network performance or troubleshoot problems with…
