Although encryption won’t prevent sniffing, it renders any data captured during the sniffing attack useless because hackers can’t interpret the information. The best security defense against a sniffer on the network is encryption. In many cases, span ports are used by network administrators to monitor traffic for legitimate purposes. A switch network has greatly improved throughput and is more secure than a shared network connected via hubs.Īnother way to sniff data through a switch is to use a span port or port mirroring to enable all data sent to a physical switch port to be duplicated to another port.

This enables the switch to segment the network traffic and send traffic only to the correct destination MAC addresses. The switch maintains a MAC table of all the systems and the port numbers to which they’re connected. The switch looks at the data sent to it and tries to forward packets to their intended recipients based on MAC address.

In networks that use hubs or wireless media to connect systems, all hosts on the network can see all traffic therefore, a passive packet sniffer can capture traffic going to and from all hosts connected via the hub. As the names indicate, active sniffing is detectable but passive sniffing is not detectable. Passive sniffing involves listening and capturing traffic, and is useful in a network connected by hubs active sniffing involves launching an Address Resolution Protocol (ARP) spoofing or traffic-flooding attack against a switch in order to capture traffic. There are two different types of sniffing: passive and active. Protocols such as HTTP, POP3, Simple Network Management Protocol (SNMP), and FTP are most commonly captured using a sniffer and viewed by a hacker to gather valuable information such as usernames and passwords.

Not all Windows drivers support promiscuous mode, so when using hacking tools ensure that the driver will support the necessary mode.Īny protocols that don’t encrypt data are susceptible to sniffing. Many of the hacking tools for sniffing include a promiscuous-mode driver to facilitate this process. Promiscuous mode is enabled on a network card with the installation of special driver software. In promiscuous mode, a NIC reads all traffic and sends it to the sniffer for processing. However, many hacking tools change the system’s NIC to promiscuous mode. Normally, a system on the network reads and responds only to traffic sent directly to its MAC address.

Sniffer software works by capturing packets not destined for the sniffer system’s MAC address but rather for a target’s destination MAC address.
