During the first decade of the 21^st century, Internet censorship in Belarus has evolved into a government tool used to combat political dissent. State-sponsored denial of service (DoS) attacks against civil society have become a domestic crisis that threatens not only freedom of expression in Belarus, but also the integrity of Internet resources throughout Europe. The ongoing cyber conflict between state and non-state actors in Belarus is analogous to the struggle between the Russian government and its internal adversaries in cyberspace. In this essay, we recount the history of cyber censorship and attacks against Charter '97, a popular Belarusian website, and discuss the effectiveness of countermeasures.
