Deep-Packet, SSL and SSH-Inspection
The “Deep Packet Inspection” (DPI), alternatively “Complete Packet Inspection” or “Information eXtraction” (IX) is a process in network technology that monitors and filters data packs. Here, the data and header part of a data pack are monitored by special features such as protocol violations, viruses, spam and other unwanted content. Unlike classical packet filters that only monitors the header part, DPI also includes the data part. DPI may also be used for the regulation of data streams.
