Network Sovereignty - Definition from the Hotspot Shield Glossary
The sovereignty of a network involves a governing body attempting to assert control and a form of law enforcement over a computing infrastructure such as a national internet or national intranet. This works in the same way as sovereign control over a countries border for example.
Network sovereignty has been implemented in several countries, the most notable of which is the “Great firewall of China”, the Roskomnadzor initiative in Russia, and SOPA-PIPA act in the United States. All of these instances are where a government has exercised a level of control over the internet or a public network, or enforced laws with the aim of controlling the public’s behavior on the internet.
