Introduction

When any data is to be transferred to a computer network, it is divided into units in the sender area called the data packets and reassembled in the recipient space in its original format. A small computer network communication unit. The action of capturing data packets is called the sniffed packet.

Sniffer is a program that listens to network traffic by capturing network information. They work because Ethernet is built around a shared system. Most networks use broadcast technology when one computer message is read by another computer in that network. In fact, all computers other than the targeted message will ignore that message. However, computers can be programmed to receive messages even if they are not intended for them. This is done by sniffing. By using a sniffer, the attacker can capture packets like DNS traffic, web traffic, email, and other types of data traffic. By downloading these packets, the attacker may disclose information such as data, username, and passwords from agreements such as HTTP, SMTP, IMAP, POP, FTP, and Telnet. The sniffing process is done using loose holes. This paper covers the function of the inhalation package, the odor-detected agreements, the tools used for inhalation, the defense strategies against odor attack, and the detection strategies.
