Packet capture is a cybersecurity and digital networking term for intercepting a data packet that is migrating or crossing over a specific computer network. Once a packet is already captured, it is stored temporarily so that it can be analyzed. The packet is observed and investigated to aid in a diagnosis to then solve network related issues and determine whether network security policies are being obeyed. Hackers can also use packet capturing techniques to take data that is being transmitted through a network.

Network directors or SOC managers analyze and are tasked with commanding overall network traffic and performance. To examine and apprehend running packets in real-time over a network, there is a ride-array of packet capture techniques utilized such as forensics, identifying packet loss, troubleshooting, and last but not least, security. A packet capture can be used in one of two ways: legitimately or illegitimately. Through legitimate channels, sniffing seizes the data and then subsequently transmissions the errors to safeguard effective network communication.
