![]() However, they can only accomplish this if security vulnerabilities exist in your network or if you use weak credentials for your accounts.įor a better understanding of what packet sniffing is, let’s take a look at the Open Systems Interconnection (OSI) model, which manages the Internet. Interestingly, nefarious actors also employ packet sniffing to steal user data. It also assists in identifying the network’s traffic pattern or how traffic travels from one node to another. ![]() It allows engineers to troubleshoot network latency or speed. Packet sniffing also ensures that a network is functioning correctly. By doing so, they can ensure that the packet contents are not forged or malicious. Through this mechanism, security engineers can analyze and monitor network traffic and determine if the packets are formatted as per Internet standards. Packet sniffing decodes the content of these packets for later inspection, but it cannot change it. A network packet contains information about the user, its source and destination, and its user’s browser version, among others. ![]() Packet sniffing refers to the use of an appliance or program (known as a “packet analyzer”) to capture data packets or data units that cross a network.
