Detecting and stopping attacks that could cause massive network damage is a major challenge. Organisations often find it difficult to examine and monitor network traffic. With security being a huge concern, organisations are looking for improvement over conventional packet analysis that only examine packet headers because attackers are getting better at hiding malicious payloads in plain sight.
Deep Packet Inspection (DPI) is an advanced monitoring technique to inspect and vet the payload of packets. The main advantage of DPI is that it provides the most accurate information on bandwidth since it reads the packet. By studying metadata using deep packet inspection (DPI), network specialists can learn how to best optimise servers to reduce overhead, detect hackers, combat malware, and get intimate details about user behavior.
DPI typically entails decoding of packets above OSI Layer 4. It is used to identify the network protocol. It is also used to identify the application.
There are two major DPI applications and Cubro devices can perform both of these functions:
