It is plugged into an ethernet port of your network and will ensure that all packets are filtered and read. Hardware packet sniffersĪ hardware packet sniffer is a physical device that is plugged into a network. Depending on how the network is configured, multiple packet sniffers may be required in order to get comprehensive coverage throughout all network segments. If not encrypted, sniffers can read its contents and make a log of it before it passes on to its assigned destination or address. This will allow the packets to be intercepted and recorded. On a switched network, packet sniffing will require a workaround such as injecting address resolution protocols (ARPs). Instead, they can be configured to receive every single packet transferred across a network hub. In network hubs, each device connected to the network is capable of receiving any packet being transferred but is programmed to ignore those not intended for them. Packets are constantly flowing across different channels before they reach their destination. Once the packets reach their destination, the network reassembles them and completes the transfer of data to device B. This is done to allow the network to find the most efficient route of transfer. After receiving the data, the network will first break it down into smaller, more manageable parts called packets. Say, for example, device A wants to transfer a chunk of data to device B. The purpose of a network is to provide a basis for the transfer of data between devices. Packet sniffing is used to capture data such as web browsing histories, usernames and passwords, bandwidth usage, and much more.

Network administrators or cyber criminals engage in packet sniffing by using packet sniffers, which are either physical devices or software applications. Packet sniffing is the action of detecting, reading, and recording packets of data being sent across a network. This article will go into detail about what packet sniffing is, how it works, and how it is used. A solid foundational understanding of terms like packet sniffing is necessary to gain a proper foothold in today’s world of cyber security. Both network administrators and cyber criminals may use packet sniffers for legitimate and malicious purposes respectively. Networks are constantly transferring pieces of data as segmented packets.
