Middleeast-IranFor some time, I’ve been keeping an eye on how the Iranian government monitors, mediates, and influences data traffic on public networks. This has seen me write several posts, here and elsewhere, about the government’s usage of deep packet inspection, the implications of Iranian government surveillance, and the challenges posed by Iranian ISPs’ most recent network updates. Last month I was invited to give a talk at the Pacific Centre for Technology and Culture about the usage of deep packet inspection by the Iranian and Tunisian governments.


Faced with growing unrest that is (at least in part) facilitated by digital communications, repressive nation-states have integrated powerful new surveillance systems into the depths of their nations’ communications infrastructures. In this presentation, Christopher Parsons first discusses the capabilities of a technology, deep packet inspection, which is used to survey, analyze, and modify communications in real-time. He then discusses the composition of the Iranian and Tunisian telecommunications infrastructure, outlining how deep packet inspection is used to monitor, block, and subvert encrypted and private communications. The presentation concludes with a brief reflection on how this same technology is deployed in the West, with a focus on how we might identify key actors, motivations, and drivers of the technology in our own network ecologies.
