Deep Packet Inspection (DPI)September 20, 2021 Off By Tobias
Deep Packet Inspection stands for a method in network technology to monitor and filter data packets. The data part and the header part of the data packet are examined simultaneously for certain features such as protocol violations, computer viruses, spam and other unwanted content.
DPI is currently mostly used in enterprise applications by providers, often on behalf of governments, in a wide variety of application areas. It enables significant protection of information flows, but is also used for data retention, eavesdropping and information gathering, and censorship on the Internet. Critics also fear that DPI technology could be used in the future to restrict the net neutrality of the Internet. In Turkey, DPI is used by providers to redirect the official download pages when downloading popular software such as VLC, WinRAR, Skype, 7-Zip or Opera, and to serve spyware-infected software.
