Mitigating Online Censorship

Ve Sin Filtro
The course will help you understand the various forms of internet censorship, how and when they might occur, and safe methods for circumventing them.
About this course:
As repressive governments fight for ever-increasing control of information flows and access, the ubiquity of the internet as a tool for exercising freedom of speech makes it an all-too-common target for censorship. Some countries like China have institutionalised such censorship with national-scale surveillance infrastructure like the Great Firewall, effectively monitoring and controlling what people can access on the internet, in violation of their basic human rights. In this course, we will explore internet censorship in more detail, using several case studies to demonstrate how you can navigate techniques and tools for circumventing these restrictions.
What do I learn:
By the end of the course, you will be able to: Understand internet censorship, how it works, and when it can occur Build a map of the various forms of internet censorship using country case studies Navigate various forms of censorship using selected tools and techniques
What do I need to know:
The course is designed for people living, working or providing internet freedom and digital safety support to communities in repressive regions.
